(877) 420-1330 7 QUESTCLIMATE.COM QUEST 225 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS DUCTING TO HVAC OPTIONS A. HVAC SUPPLY TO SUPPLY CAUTION! To avoid the dehumidifier cycling in and out of DEFROST, it is recommended that the leaving air temperature of the A/C coil is not below 55°F. Also, this install is not recommended for climates where the heating system will run during the spring and fall times of year, as this could diminish the water removal capability of the dehumidifier. If the Check Damper is not used, it is important to have the HVAC system fan ON when the dehumidifier is ON to prevent backflow of air. WARNING! Due to pressure resistance it is not recommended to use the optional outdoor air intake when installing the dehumidifier supply to supply. B. DEDICATED RETURN TO SUPPLY (877) 420-1330 8 QUESTCLIMATE.COM QUEST 225 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS CAUTION! PLEASE NOTE: Return to Return installs are to be considered last resort options and are not recommended. The dehumidifier will heat the AC cooling coils which diminishes the amount of water the AC system will remove when operating. If this installation is chosen, the dehumidifier must activate the HVAC blower and AC calls need to lock out the dehumidifier from running. Please check your local codes prior to installing. C. DEDICATED QUEST RETURN TO HVAC RETURN Quest 225 Indoor Air Return Create a separate return for the Quest 225 Dehumidifierin a central area of the building. Installing the supply air from the Quest 225 Dehumidifier to the return of the HVAC system requires the HVAC fan to run when the Quest Dehumidifier is operating. D. HVAC RETURN TO HVAC RETURN NOTE: If Check Damper is not in place, the HVAC fan must ON when the dehumidifier is in operation. (877) 420-1330 9 QUESTCLIMATE.COM QUEST 225 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS E. HVAC RETURN TO HVAC SUPPLY Check damper should be in place between the Return and Supply connections of the dehumidifier. If the Check Damper is not in place, the HVAC fan must be ON when the dehumidifier is in operation. Anything greater than 0.4" of static requires HI fan setting. Anything greater than 0.7" of static requires HI override (99). Anything greater than 0.9" is not recommended. F. NO EXISTING DUCTWORK INSTALLATION When installing the Quest 225 Dehumidifier in a structure that does not have a forced-air HVAC system, a single return for the dehumidifier should be installed in a central location. The supply air should be ducted back into the space you want to dry. Proper air distribution is important for optimal performance of the dehumidifier. Install a 6" insulated duct from outside, teeing into the 14" return duct of the Quest 225 Dehumidifier to provide outdoor air ventilation (optional). A 14" diameter duct is recommended for branches to larger areas.

Servicing the Quest 225 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 The Quest 225 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 expanion device which causes the refrigerant pressure and temperature to drop. It next enters the evaporator coil where it absorbs heat from the incoming air and evaporates. The evaporator operates in a flooded condition, which means that all the evaporator tubes contain liquid refrigerant during normal operation. A flooded evaporator should maintain nearly constant pressure and temperature across the entire coil, from inlet to outlet. The compressor collects the cool refrigerant gas 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 225 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 225 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 » 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. (877) 420-1330 17 QUESTCLIMATE.COM QUEST 225 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS » 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. 7.3A 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. 7.3B 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. CONTINUES ON NEXT PAGE (877) 420-1330 18 QUESTCLIMATE.COM QUEST 225 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS » 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. 7.3C 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. 7.3D 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 re-calibration. (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. » If a leak is suspected, all open flames shall be removed/extinguished.

Test each component for continuity. See the appropriate section if a defect is suspected. 3. Unplug the unit and then disconnect the connector from the side of the compressor. Using an ohmmeter, check continuity between the points listed below. 4. Compressor terminals C and S: No continuity indicates an open start winding. The compressor must be replaced. Normal start winding resistance is 3 to 7 ohms. 5. Compressor terminals C and R: No continuity indicates an open run winding. The compresor must be replaced. Normal run winding resistance is .5 to 2 ohms. 6. Compressor terminal C and compressor case: Continuity indicates a grounded motor. The compressor must be replaced. 7. Disconnect the wires from the run capacitor. The capacitor is shorted and must be replaced if continuity exists between any terminal and ground. 8. Using capacitor or MFD setting on meter test between both capacitor terminals. Compare reading to capacitor spec on capacitor. 9. If the above test pass but the compressor does not work, the compressor has an internal mechanical defect and must be replaced. (877) 420-1330 23 QUESTCLIMATE.COM QUEST 225 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS 7.7B REPLACING A BURNT COMPRESSOR The refrigerant and oil mixture in a compressor is chemically very stable under normal operating conditions. However, when an electrical short occurs in the compressor motor, the resulting high temperature arc causes a portion of the refrigerant oil mixture to break down into carbonaceous sludge, a very corrosive acid, and water. These contaminants must be carefully removed otherwise even small residues will attack replacement compressor motors and cause failures. The following procedure is effective only if the system is monitored after replacing the compressor to insure that the clean up was complete. 1. This procedure assumes that the previously listed compressor motor circuit tests revealed a shorted or open winding. 2. Remove and properly dispose of the system charge. DO NOT vent the refrigerant or allow it to contact your eyes or skin. 3. Remove the burned out compressor. Use rubber gloves if there is any possibility of contacting the oil or sludge. 4. To facilitate subsequent steps, determine the type of burn out that occurred. If the discharge line shows no evidence of sludge and the suction line is also clean or perhaps has some light carbon deposits, the burn out occurred while the compressor was not rotating. Contaminants are therefore largely confined to the compressor housing. A single installation of liquid and suction line filter/driers will probably clean up the system. If sludge is evident in the discharge line, it will likely be found in the suction line. This indicates the compressor burned out will running. Sludge and acid have been pumped throughout the system. Several changes of the liquid and suction filter/driers will probably be necessary to cleanse the system. 5. Correct the system fault that caused the burn out. Consult the factory for advice. 6. Install the replacement compressor with a new capacitor and an oversized liquid line filter. In a running burn out, install an oversized suction line filter/drier between the accumulator and compressor. Thoroughly flush the accumulator with refrigerant to remove all trapped sludge and to prevent the oil hole from becoming plugged. A standing burn out does not require a suction line filter/drier. 7. Evacuate the system with a good vacuum pump and accurate vacuum gauge. Leave the pump on the system for at least an hour. 8. Operate the system for a short period of time, monitoring the suction pressure to determine that the suction filter is not becoming plugged. Replace the suction filter/drier if pressure drop occurs. If a severe running burn out has occurred, several filter/driers may have to be replaced to remove all of the acid and moisture. NOTE: NEVER USE THE COMPRESSOR TO EVACUATE THE SYSTEM OR ANY PART OF IT. 7.7C REPLACING A COMPRESSOR, NON BURN OUT Remove the refrigerant from the system. Replace the compressor and liquid line filter/drier. Charge the system to 50 PSIG and check for leaks. Remove the charge and weigh in the refrigerant quantity listed on the nameplate. Operate the system to verify performance. (877) 420-1330 24 QUESTCLIMATE.COM QUEST 225 INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS 7.8 REMOTE CONTROLS The Quest 225 dehumidifier is controlled by devices mounted on a panel that is remote from the unit. You may or may not have the devices listed below depending on the model of the remote hygrostat you purchased. If the Quest 225 dehumidifier fails to operate as desired, always check the settings of the controls to ensure that they are correct. Check that the controls are receiving 24VAC from the Quest 225 Dehumidifier. Check the connections between the Quest 225 dehumidifier, the hygrostat, and the field control wiring. 7.8A HUMIDITY CONTROL The humidity control is an adjustable switch that closes when the relative humidity of the air in which it is located rises to the set point. It opens when the RH drops 4 to 6% below the set point. If the Quest 225 dehumidifier does not run, try turning the humidity control Down using arrow on control pad. If it then runs, the humidity control is out of calibration or the RH is below setpoint. 7.9 DEFROST SYSTEM The Quest 225 Dehumidifier is equipped with an automatic defrost mechanism. If the Quest 225 Dehumidifier operates in conditions that develop frost on the evaporator, it will sense the frost build-up and automatically defrost the evaporator. The Quest 225 Dehumidifier may not appear to be operating correctly during the defrost sequence, but once the defrost sequence is completed, the Quest 225 Dehumidifier will resume dehumidifying. The evaporator temperature sensor is installed into the center of the evaporator coil. It will automatically shut the compressor off if the temperature drops due to excessive frost formation on the evaporator coil. The impeller fan will continue to run, causing air to flow through the evaporator coil and melt the ice. When the ice has melted, the evaporator temperature will rise, and the control will restart the compressor. 7.10 CONDENSATE PUMP KIT An optional condensate pump kit is available from the factory for use with the Quest 225 Dehumidifier. Condensate is automatically pumped to a remote location when the water level in the pump's reservoir rises to close the float switch. The pump also contains a safety float switch. The white leads from this switch extend from beneath the pump cover. These leads should be extended to the FLOAT terminals on the terminal block and the factory float jumper removed. If the pump fails, the safety switch opens causing the compressor to stop and water production to cease before the reservoir overflows. E4 will be displayed on the control panel. The Quest 225 Dehumidifier will not dehumidify until this switch closes.
