MAINTENANCE WARNING! Do not operate the unit without the filter or with a less effective filter. The heat exchange coils inside the unit could become clogged and require disassembly to clean. Filter non-compliance invalidates the product warranty. 6.1 STANDARD AIR FILTER The Quest 506 Dehumidifier ships with a standard MERV 13 efficient pleated fabric filter. This filter should be checked every six months. Operating the unit with a dirty filter will reduce dehumidifier capacity and efficiency and may cause the compressor to cycle off and on unnecessarily on the defrost control. To access the air filter, the filter should be readily visible and can be removed by pulling it straight out of the Quest 506 Dehumidifier. We recommend changing the filter every 3-6 months, or in growing environments, at least with every grow cycle. 7. SERVICE WARNING! Servicing the Quest 506 with its high pressure refrigerant system and high voltage circuitry presents a health hazard which could result in death, serious bodily injury, and/or property damage. Only qualified service people should service this unit. 7.1 WARRANTY A warranty certificate has been enclosed with this unit; read it before any repair is initiated. If a warranty repair is required, call the factory first at 1-877-420-1330 for warranty claim authorization and technical assistance. 7.2 TECHNICAL DESCRIPTION (NON STANDARD PATENTED) The Quest 506 Dehumidifier uses a refrigeration system similar to an air conditioner's to remove heat and moisture from incoming air, and add heat to the air that is discharged. Hot, high-pressure refrigerant gas is routed from the compressor to the condenser coil. The refrigerant is cooled and condensed by giving up its heat to the air that is about to be discharged from the unit. The refrigerant liquid then passes through a filter/drier and expansion drier which causes the refrigerant pressure and temperature to drop. It next enters the evaporator coil where the cool refrigerant absorbs heat from the incoming air and evaporates. The compressor evacuates the cool refrigerant vapor from the evaporator and compresses it to a high pressure and temperature to repeat the process. 7.3 SERVICE PERSONNEL Only qualified HVAC or electrical contractors are allowed to conduct maintenance, service and/or repair operations on Quest 506 machines. Examples include but are not limited to breaking into the refrigerating circuit, opening of sealed components, and/or opening of ventilated enclosures. Prior to beginning work on the Quest 506 machine, safety checks are necessary to ensure that the risk of ignition is minimized. » For repair to the REFRIGERATING SYSTEM, a qualified contractor should first establish a controlled procedure so as to minimize the risk of a flammable gas or vapor being present while the work is being performed. (877) 420-1330 11 QUESTCLIMATE.COM QUEST 506 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS » 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 shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe. » If any hot work is to be conducted on the refrigerating 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 » No person carrying out work in relation to a REFRIGERATING SYSTEM which involves exposing any pipe work 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 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. » 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. The following checks shall be applied to installations using FLAMMABLE REFRIGERANTS: » Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times Therma-Stor's maintenance and service guidelines shall be followed. If in doubt, consult Therma-Stor's technical department for assistance. » The actual REFRIGERANT CHARGE 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. » Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected. » Dehumidifiers 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. 7.4 CHECKS TO ELECTRICAL DEVICES Repair and maintenance to electrical components shall 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 shall be used. This shall be reported to the owner of the equipment so all parties are advised. Initial safety checks shall include: · that capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking. · that no live electrical components and wiring are exposed while charging, recovering or purging the system. · that there is continuity of earth bonding. (877) 420-1330 12 QUESTCLIMATE.COM QUEST 506 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS 7.5 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. » Ensure that the equipment is mounted securely. » Ensure that seals or sealing materials have not degraded to the point that they no longer serve the purpose of preventing the ingress of flammable atmospheres » Replacement parts shall be in accordance with Therma-Stor specifications. 7.6 REPAIRS 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 Therma-Stor. Other parts may result in the ignition of refrigerant in the atmosphere from a leak. » NOTE The use of silicon sealant can inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components do not have to be isolated prior to working on them. » 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. 7.7 DETECTION OF FLAMMABLE REFRIGERANTS » Under no circumstances shall 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) shall not be used. » The following leak detection methods are deemed acceptable for all refrigerant systems: · Electronic leak detectors may be used to detect refrigerant leaks but, in the case of FLAMMABLE REFRIGERANTS, the sensitivity may not be adequate, or may need recalibration. (Detection equipment shall 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 shall be set at 25% LFL of the refrigerant and shall be calibrated to 454B. · Leak detection fluids are also 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 pipe. NOTE EXAMPLES OF LEAK DETECTION FLUIDS ARE: · bubble method · fluorescent method agents CONTINUES ON NEXT PAGE (877) 420-1330 13 QUESTCLIMATE.COM QUEST 506 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS » If a leak is suspected, all open flames shall be removed/extinguished. » If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak. Removal of refrigerant shall be according to Clause DD.9 of 60335-2-40. 7.8 REFRIGERANT REMOVAL AND EVACUATION When breaking into the refrigerant circuit to make repairs or for any other purpose conventional procedures shall be used. However, for FLAMMABLE REFRIGERANTS it is important that best practice is followed since flammability is a consideration. The following procedure shall be adhered to: · remove refrigerant · purge the circuit with inert gas (optional for A2L) · evacuate (optional for A2L) · purge with inert gas (optional for A2L) · open the circuit by cutting or brazing · The REFRIGERANT CHARGE shall be recovered into the correct recovery cylinders. Compressed air or oxygen shall not be used for purging refrigerant systems. · Ensure that the outlet for the vacuum pump is not close to any POTENTIAL IGNITION SOURCES and that ventilation is available. 7.9 CHARGING PROCEDURES In addition to conventional charging procedures, the following requirements shall be followed: » Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them. » Cylinders shall be kept in an appropriate position according to the instructions. » Ensure that the REFRIGERATING SYSTEM is grounded prior to charging the system with refrigerant. » Label the system when charging is complete (if not already). » Extreme care shall be taken not to overfill the REFRIGERATING SYSTEM. » Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall be leak-tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site. 7.10 TROUBLESHOOTING Neither fan nor compressor running. Dehumidification is being called for. No fan call. 1.

DECOMMISSIONING Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its details. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of recovered refrigerant. It is essential that electrical power is available before the task commences. 1. Become familiar with the equipment and its operation. 2. Isolate system electrically. 3. Before attempting the procedure, ensure that: · mechanical handling equipment is available, if required, for handling refrigerant cylinders; · all 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. 4. Pump down refrigerant system, if possible. 5. If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system. 6. Make sure that cylinder is situated on the scales before recovery takes place. 7. Start the recovery machine and operate in accordance with instructions. 8. Do not overfill cylinders (no more than 80 % volume liquid charge). 9. Do not exceed the maximum working pressure of the cylinder, even temporarily. 10. When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off. 11. Recovered refrigerant shall not be charged into another REFRIGERATING SYSTEM unless it has been cleaned and checked. 8.1 LABELING DECOMMISSIONED MACHINES Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. For appliances containing FLAMMABLE REFRIGERANTS, ensure that there are labels on the equipment stating the equipment contains FLAMMABLE REFRIGERANT. 8.2 REFRIGERANT 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 labelledfor 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. (877) 420-1330 16 QUESTCLIMATE.COM QUEST 506 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS » 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 all appropriate refrigerants including, when applicable, 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 shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.
