Information on Servicing:

1. Checking the area: Prior to working on systems with flammable refrigerants, conduct safety checks to minimize ignition risk. Follow precautions before working on the refrigerating system.
2. Work procedure: Undertake work under a controlled procedure to minimize the risk of flammable gas or vapor.
3. General work area: Instruct all staff on the nature of the work. Avoid confined spaces. Section off the workspace and ensure the area is made safe by controlling flammable material.
4. Checking for presence of refrigerant: Use an appropriate refrigerant detector to check for flammable atmospheres. Ensure leak detection equipment is suitable for flammable refrigerants (non-sparking, sealed, or intrinsically safe).
5. Presence of a fire extinguisher: Have a dry powder or CO2 fire extinguisher available for hot work on refrigeration equipment.
6. No ignition sources: Do not use ignition sources when working on refrigeration systems containing flammable refrigerants. Keep all ignition sources, including smoking, far from the work site. Survey the area for flammable hazards or ignition risks and display "No Smoking" signs.

Ventilated Area and Equipment Checks:

• Ventilated area: Ensure the area is open or adequately ventilated before breaking into the system or conducting hot work. Ventilation should continue during work to disperse released refrigerant.
• Checks to the refrigeration equipment: Electrical components must be fit for purpose and to specification. Follow manufacturer's maintenance and service guidelines. Consult the manufacturer's technical department if in doubt. Checks for flammable refrigerant installations include: charge size relative to room size, ventilation machinery operation, secondary circuit checks (if indirect), legible markings, and protection of components from corrosive substances.

Electrical Device Checks and Sealed Component Repairs:

• Checks to electrical devices: Initial safety checks and component inspection are required for repairs. If a fault compromises safety, do not connect power until resolved. Temporary solutions must be reported to the owner. Initial checks include discharging capacitors safely, ensuring no exposed live components during charging/recovering/purging, and checking earth bonding continuity.
• Repairs to sealed components: Disconnect all electrical supplies before opening sealed covers. If electrical supply is necessary during servicing, use a permanently operating leak detector. Ensure casing is not altered in a way that affects protection (e.g., cable damage, excessive connections, incorrect seals/glands).

Intrinsically Safe Components, Cabling, and Leak Detection:

• Seals and materials: Ensure seals and sealing materials are not degraded and prevent ingress of flammable atmospheres. Use manufacturer-specified replacement parts. Note: Silicon sealant may inhibit leak detection. Intrinsically safe components can be worked on live.
• Repair to intrinsically safe components: Do not apply permanent inductive or capacitance loads that exceed equipment limits. Intrinsically safe components are the only ones that can be worked on live in a flammable atmosphere. Test apparatus must be correctly rated. Replace components only with manufacturer-specified parts.
• Cabling: Check cabling for wear, corrosion, pressure, vibration, sharp edges, or other adverse effects, including aging and vibration from compressors/fans.
• Detection of flammable refrigerants: Do not use ignition sources (e.g., halide torch) for leak detection.
• Leak detection methods: Acceptable methods include electronic leak detectors (ensure calibration and suitability for refrigerant). Leak detection fluids are suitable, but avoid those with chlorine. If a leak is suspected, extinguish all naked flames. For brazing, recover all refrigerant or isolate the area. Purge with oxygen-free nitrogen (OFN) before and during brazing.

The LED display shows the current relative humidity level (35%-85%), auto start/stop settings (0.0-24), or desired humidity level. Accuracy is ±5% for humidity levels between 30% and 90%.

Other Features:

• BUCKET FULL LIGHT: Illuminates when the bucket is full or not properly seated.
• AUTO DEFROST: Automatically enters defrost mode when frost/ice builds up on evaporator coils. Compressor cycles off, fan continues to run until frost disappears. Auto Defrost indicator light illuminates.
• AUTO SHUT OFF: Shuts off when the bucket is full, removed, or not replaced correctly. Compressor also shuts off when desired humidity is reached. Fan runs for an additional 3 minutes. 3PFDP50 models activate the water pump when the bucket is full.
• AUTO-RESTART: Unit restarts with previous settings after an unexpected power interruption.

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 illuminates.
• If the unit is ON and the bucket is full, the compressor and fan turn off. The FULL indicator light illuminates, and the LED display shows code P2.

Empty and Reinsert the Bucket:

• Grip the bucket handles securely and pull out straight to avoid spilling water. Do not place the bucket on the floor as it may be uneven.
• Code EB shows on the display when the bucket is removed. Empty the water into a drain.
• The bucket must be replaced carefully and securely for the dehumidifier to operate. Code EB disappears, and the unit restarts with last used settings after correct replacement.

For 3PFDP50 model only: Before reinserting the bucket, the pump arm on the right-side of the bucket area must be lifted back into position.

[Diagram description: Illustration shows partially removing the bucket, then fully removing it.]

[Diagram description: For 3PFDP50 models, an illustration shows the pump arm needing to be pushed back up before reinserting the bucket. It also shows the pump hose drops and how to reinstall the pump hose properly.]

Notes on Bucket Handling:

• Do not touch internal parts when removing the bucket, as this may damage the product.
• Push the bucket gently all the way into the unit. Banging or insecure insertion may prevent operation.
• If the pump hose drops when removing the bucket, reinstall it properly before replacing the bucket.
• If water remains in the unit after bucket removal, dry it.
• If the bucket is removed while running, the unit beeps 8 times and displays P2. The same occurs if removed while off.

2. Continuous Draining:

Continuous drainage uses gravity to remove water through a hose. Unscrew the white screw cap covering the continuous drain outlet to attach the hose. Seal the outlet with the cap when not in use to prevent leaks.

• A small water pan is installed to route water out as it's created. Dehumidifiers are designed for level floors. If the unit is on an unleveled or slightly forward angle, water will run into the bucket as a backup.
• Basement floors typically slope towards the floor drain. Position the unit so the back panel faces the floor drain.
• The continuous drain hose must always be placed at a downward angle. A maximum 6ft length is recommended to prevent backups. Upward angles or sharp bends can cause water to get stuck or back up into the unit.
• A maximum 6ft garden hose (ID≥5/16", not included) with a female threaded end (ID:M=1", not included) can be used. The unit is not designed to secure a vinyl hose, which can cause leaks.

[Diagram description: Illustration shows the rear of the unit with labels for "Continuous Drain Outlet" and "Drain Hose".]

3. Pump Drainage (3PFDP50 ONLY):

Water pumps offer flexibility, allowing water to be pumped vertically up to 16FT and horizontally up to 40FT. This is useful for draining to a window, distant floor drain, or sink.

• The pump activates when the water bucket is completely full and expels approximately 32oz of water (half the bucket) before stopping.
• A maximum 40FT length hose (OD=1/4", included) can be used.
• To install the hose, push it into the pump drain outlet to a depth of at least 1/2 inch (approx. 15 mm). The holder will lock it in place. Place the other end in a floor drain or desired drainage location.
• Press the PUMP button on the display panel to activate the pump feature. The pump light indicator must be on, and the bucket must be full.
• It is recommended to empty and clean the water bucket weekly to prevent stagnant water and mold growth.
• Remove the hose when the pump feature is not in use. To remove, press the plastic ring around the pump hose outlet and gently pull. Do not force detachment by only pulling the hose, as this can damage the unit. Residual water may expel when removing the hose.

[Diagram description: Illustration shows the rear of the unit with labels for "Continuous Drain Port/Cover", "Pump Drain Hose", and "Pump Drain Port".]

Pump Operation Notes:

[Diagram description: Close-up of hands pushing in on the edge of the pump inlet and simultaneously pulling out the hose.]

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.

The pump may make a noticeable sound for 3-5 minutes on startup; this is normal.

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

Troubleshooting Pump Issues:

• Remove the bucket, 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 from the bucket.
• Reinstall the pump hose if it was disconnected 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, as this may cause electrical shock, deteriorate insulation, or cause rust.
• The air intake and outlet grilles soil easily; use a vacuum attachment or brush to clean them.

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 mold, mildew, and bacteria growth. Partially fill with clean water and a little mild detergent, swish, empty, and wipe dry with a soft cloth. Rinse.

Cleaning the Air Filter:

• The filter is integrated with the back panel of the unit and is not a separate item.
• Clean the filter every two weeks based on normal operating conditions.
• To remove the filter, pull it outwards.
• Wash the filter with clean water, then dry it.
• Re-install the filter and replace the bucket.

[Diagram description: An illustration shows the back of the dehumidifier with an arrow pointing to the air filter location.]

Do not operate the dehumidifier without a filter, as dirt and lint will clog it and reduce performance.

Preparing for Storage:

• When not using the unit for long 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.
