Information on servicing

1. Checking the area
   • Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system.
2. Work procedure
   • Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or vapor being present while the work is being performed.
3. General work area
   • All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the conditions within the area have been made safe by control of flammable material.
4. Checking for presence of refrigerant
   • The area should be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
5. Presence of a fire extinguisher
   • If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area.
6. No ignition sources
   • No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and disposal, during which flammable refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. No Smoking signs shall be displayed.

(Continued)

⚠️ WARNING (For using R290/R32 refrigerant only)

7. Ventilated area

• Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.

8. Checks to the refrigeration equipment

• Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer's maintenance and service guidelines shall be followed. If in doubt consult the manufacturer's technical department for assistance.
• The following checks shall be applied to installations using flammable refrigerants:
  • The charge size is in accordance with the room size within which the refrigerant containing parts are installed.
  • The ventilation machinery and outlets are operating adequately and are not obstructed.
  • If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant.
  • Marking to the equipment continues to be visible and legible. Markings and signs that are illegible should be corrected.
  • Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded.

9. Checks to electrical devices

• Repair and maintenance to electrical components should include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution should be used. This should be reported to the owner of the equipment, so all parties are advised.
• Initial safety checks should include:
  • That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking.
  • That there are no live electrical components and wiring exposed while charging, recovering or purging the system.
  • That there is continuity of earth bonding.

10. Repairs to sealed components

• During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
• Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected. This shall include damage to cables, excessive number of connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.

(Continued)

⚠️ WARNING (For using R290/R32 refrigerant only)

• Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts should be in accordance with the manufacturer's specifications.

NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components do not have to be isolated prior to working on them.

11. Repair to intrinsically safe components

• Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use. Intrinsically safe components are the only types that can be worked on while live in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating.
• Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.

12. Cabling

• Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.

13. Detection of flammable refrigerants

• Under no circumstances, should potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) should not be used.

14. Leak detection methods

• The following leak detection methods are deemed acceptable for systems containing flammable refrigerants. Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need re-calibration. (Detection equipment should be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment should be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25% maximum) is confirmed.
• Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipework.
• If a leak is suspected, all naked flames should be removed/extinguished. If a leakage of refrigerant is found which requires brazing, all of the refrigerant should be recovered from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak. Oxygen free nitrogen (OFN) should then be purged through the system both before and during the brazing process.

(Continued)

⚠️ WARNING (For using R290/R32 refrigerant only)

15. Removal and evacuation

• When breaking into the refrigerant circuit to make repairs or for any other purpose, conventional procedures shall be used. However, it is important that best practice is followed since flammability is a consideration. Opening of the refrigeration systems should not be done by brazing.
• The following procedure shall be adhered to:
  • Remove refrigerant
  • Purge the circuit with inert gas
  • Evacuate
  • Purge again with inert gas
  • Open the circuit by cutting or brazing.
• The refrigerant charge should be recovered into the correct recovery cylinders. The system should be flushed with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used for this task.
• Flushing should be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system.
• When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipework are to take place.
• Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available.

16. Charging procedures

• In addition to conventional charging procedures, the following requirements should be followed. Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines should be as short as possible to minimize the amount of refrigerant contained in them.
• Cylinders should be kept upright.
• Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
• Label the system when charging is complete (if not already).
• Extreme care should be taken not to overfill the refrigeration system.
• Prior to recharging the system, it should be pressure tested with OFN. The system should be leak tested on completion of charging but prior to commissioning. A follow up leak test should be carried out prior to leaving the site.

(Continued)

⚠️ WARNING (For using R290/R32 refrigerant only)

17. Decommissioning

• Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample should be taken in case analysis is required prior to re-use of reclaimed refrigerant. It is essential that electrical power is available before the task is commenced.
• Become familiar with the equipment and its operation.
• Isolate the system electrically.
• Before attempting the procedure ensure that:
  • When breaking into the refrigerant circuit to make repairs or for any other purpose, conventional procedures should be used.
  • Mechanical handling equipment is available, if required, for handling refrigerant cylinders.
  • Personal protective equipment is available and being used correctly.
  • The recovery process is supervised at all times by a competent person.
  • Recovery equipment and cylinders conform to the appropriate standards.
• Pump down refrigerant system, if possible.
• If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
• Make sure that cylinder is situated on the scales before recovery takes place.
• Start the recovery machine and operate in accordance with manufacturer's instructions. Do not overfill cylinders. (No more than 80% volume liquid charge).
• Do not exceed the maximum working pressure of the cylinder, even temporarily.
• When the cylinders have been filled correctly and the process is completed, make sure that the cylinders and the equipment are removed from the site promptly and all isolation valves on the equipment are closed off.
• Recovered refrigerant should not be charged into another refrigeration system unless it has been cleaned and checked.

(Continued)

⚠️ WARNING (For using R290/R32 refrigerant only)

18. Labelling

• Equipment should be labelled stating that it has been de-commissioned and emptied of refrigerant. The label should be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.

19. Recovery

• When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely.
• When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge is available. All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.
• The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of flammable refrigerants. In addition, a set of calibrated weighing scales shall be available and in good working order.
• Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult manufacturer if in doubt.
• The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and especially not in cylinders. If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the compressor to the suppliers. Only electric heating to the compressor body should be employed to accelerate this process. When oil is drained from a system, it should be carried out safely.

Removing the Collected Water

There are three ways to remove collected water:

1. Using the Bucket

• If the unit is OFF, and the bucket is full, the FULL indicator light will illuminate.
• If the unit is ON, and the bucket is full, the compressor and fan will turn off. Then, the full indicator light will illuminate and the LED display will show code P2.

Empty and Reinsert the Bucket...

• Grip the left and right bucket handles securely, and carefully pull out straight so water does not spill. Do not place the bucket on the floor because the bottom of the bucket is uneven and the water may spill. Code EB will show on the display panel when the bucket is removed. Empty the water from the bucket into a drain.
• The bucket must be replaced carefully and securely for the dehumidifier to operate. The code EB will disappear from the display panel, and the unit will re-start with the last used settings after the bucket is returned to its correct position.

NOTE: For 3PFDP50 model only, before reinserting the bucket, the pump arm on the right-side of the bucket area will need to be lifted back up into position.

1. Partially remove the bucket.
2. Hold both sides of the bucket with even strength, and completely remove from the unit and pour out the water.

3PFDP50 MODELS ONLY:

Pump arm needs to be pushed back up into place before reinserting the bucket.

[Diagram showing the bucket being removed and a note for the 3PFDP50 pump arm.]

• When you remove the bucket, do not touch any parts inside the unit. Doing so may damage the product.
• Be sure to push the bucket gently all the way into the unit. Banging the bucket against anything or failing to push it in securely may cause the unit not to operate.
• If the pump hose drops when you remove the bucket, you must reinstall the pump hose properly to the unit before replacing the bucket into the unit.
• If there is some water in the unit after you remove the bucket, you must dry it.
• If the bucket is removed while the unit is running, the compressor and the fan will turn off, the unit will beep 8 times, and the digital display will show P2.
• If the bucket is removed while the unit is turned off, the unit will beep 8 times, and the digital display will show P2.

2. Continuous Draining

Continuous drainage uses gravity to pull the water out of the unit through a hose. A white screw cap covers the continuous drain outlet; unscrew it to attach the continuous drain hose. The drainage outlet hose must be sealed with the provided cap when not in use. Failure to tightly seal the cap if the drain is not in use will cause leaking water.

• A small water pan inside of the unit is already installed on the optional angle to route water out as soon as the unit creates it. Dehumidifiers are designed to be used on leveled floors. If the unit is placed on an unleveled or even slightly forward angle, the water will run into the bucket as a backup.
• Basement floors will always have a slight downward slope towards the floor drain. Place the unit so the back panel is facing the floor drain.
• The continuous drain hose must be placed in a downward angle at all times. A maximum 6ft length will prevent backups on days of extra humidity. Any upward angles or sharp bends will cause the water to either become stuck inside the hose or backup into the unit.
• A maximum 6ft length garden hose (ID ≥ Ф5/16", not included) with a female threaded end (ID:M=1", not included) can be used for the continuous drainage option. The unit is not designed to secure a vinyl hose and can cause leaking water.

[Diagram showing the Continuous Drain Outlet on the back of the unit and the connection of a hose.]

3. Pump Drainage (3PFDP50 ONLY)

Water pumps provide much more flexibility for drainage options. It can pump water vertically (straight up) a maximum height of 16FT and as far as 40FT length; this is ideal for routing water out a window, to a distant floor drain, or into a sink so the unit can stay on a secure floor. The pump turns on when the water bucket is completely full and will expel 32oz of water, about half of the bucket, before stopping.

• A maximum 40FT length hose (OD=1/4", included) can be used for the pump option.
• To install the hose, make sure it is pushed into the pump drain outlet to a depth of at least 1/2 inch (approx. 15 mm). Once the hose is installed to the proper depth, the holder will lock it in place. The other end of the hose is placed in a floor drain or the location water will drain.
• Then, press the PUMP button on the display panel to turn on the water pump feature. The pump will activate only when the pump light indicator on the display is on and the water bucket is full. It will expel 32oz of water, about half the bucket, and then turn off. Recommend to completely empty the water bucket and clean it every week to prevent stagnant water and mold growth.
• The hose should always be removed when the pump feature is not being used. To remove the hose, firmly press on the plastic ring around the pump hose outlet and gently pull on the hose. Do NOT force the hose to detach from the holder by only pulling on it; this will cause permanent damage to the unit. Be aware, residual water may expel from the unit when removing the hose.

CAUTION: Do not use this operation when the outdoor temperature is equal to or less than 32°F (0°C), otherwise water will freeze inside the hose resulting in unit failure.

NOTE: The pump may make a noticeable sound for 3~5 minutes on startup. It is a normal phenomenon.

CAUTION: The pump operation light will blink at 1Hz if there is an operational failure of the pump. Please turn off the unit and unplug the power.

Check the Following Things:

• Remove the bucket from the unit, take down the pump arm and clean the pump arm mesh filter.
• Check that the pump drain hose is not kinked or blocked.
• Empty the water of the bucket.
• Reinstall the pump hose if it is disconnected from the unit and properly reinstall the bucket.
• Turn on the unit. If the error repeats, call for service.

Care and Maintenance

Turn the dehumidifier off and unplug it from the wall outlet before cleaning.

• Use water and a mild detergent. Do not use bleach or abrasives.
• Do not splash water directly onto the main unit. Doing so may cause an electrical shock, cause the insulation to deteriorate, or cause the unit to rust.
• The air intake and outlet grilles get soiled easily; use a vacuum attachment or brush to clean.

NOTE: Do not use a dishwasher to clean the bucket. After cleaning, the bucket must be replaced and securely seated for the dehumidifier to operate.

• Every week, clean the bucket to prevent growth of mold, mildew and bacteria.
• Partially fill the bucket with clean water and add a little mild detergent.
• Swish it around in the bucket.
• Empty and wipe down the inside of the bucket with a soft cloth.
• Rinse.

Cleaning the Air Filter

• THE FILTER IS INTEGRATED WITH THE BACK PANEL OF THE UNIT AND NOT A SEPARATE ITEM.
• Clean the filter every two weeks based on normal operating conditions.
• To remove the filter, pull filter outwards.
• Wash the filter with clean water then dry.
• Re-install the filter, replace bucket.

[Diagram indicating the air filter is part of the back panel.]

CAUTION: Do not operate the dehumidifier without a filter because dirt and lint will clog it and reduce performance.

Preparing for Storage

• When not using the unit for long time periods:
• After turning off the unit, wait one day before emptying the bucket.
• Clean the main unit, water bucket, and air filter.
• Allow the entire assembly to air dry.
• Wrap the cord onto the power cord handle.
• Cover the unit with a plastic bag.
• Store the unit upright in a dry, well-ventilated place.
