1. Intended Application for Quest 150 Dual The Quest 150 Dual is intended for use in light commercial structures: however, the unit can be placed in almost any setting where dehumidification is desired. Use in highly corrosive applications and pool areas may void warranty. The Quest 150 Dual works most effectively between 56° and 95°. In order to efficiently control humidity levels, the area in which the dehumidifier is to be operated must be free of water intrusion or excessive fresh (outside) air infiltration. Before installing the Quest 150 Dual, water intrusion and air infiltration problems should be addressed.

4. Installation CAUTION! Remove compressor shipping tie from the unit. Failure to remove shipping tie will cause excess vibration to be transmitted to the frame. 4.1 Remove Compressor Shipping Support The Quest 150 Dual uses a compressor to power the refrigeration system. To protect the compressor and refrigeration system during shipping a plastic tie wrap secures it to the units frame. Remove the tie wrap by cutting the tie wrap and pulling from the unit as shown. After removing tie wrap, insert plastic plugs provided into the holes. 4.2 Location The Quest 150 Dual can be installed in a variety of locations to meet the owner’s needs; other considerations include: 1. Providing access to a 115 VAC power outlet (10’ power cord is provided). 2. Locating near a floor or other suitable drain. 3. Mount at least 4” above drain. (P-trap recommended - See pg. 8) 4. Do not install the Quest 110 Dual with the exhaust of the unit within 1’ of a wall or obstruction. Do not place the unit near open water. 5. Duct work not recommended for gardening (DO NOT duct heat out). 6. Hanging not required - Floor install is ok
4.2A How to hang dehumidifier A. Attach brackets (PN 4036568) with feet. Tighten with 5/8” wrench. B. Attach chain or SunGrip to bracket. Ensure materials have adequate weight rating
4.3 Electrical Requirements The Quest 150 Dual plugs into a common grounded outlet on a 110-120 VAC 15-Amp circuit. While operating, it draws 11.0 amps @ 80°F, 60% RH and 10 amps @ 75°F, 50% RH. Use of a ground fault circuit interrupter (GFCI) protected circuit is recommended. The unit should not be used in areas prone to flooding. CAUTION! For proper drainage, the unit must be mounted so the drain outlet is at least 4” above the floor drain, and must be fully supported under the base. 4.4 Installing Feet Included with your Quest 150 Dual are four leveling feet. It is important to level the unit for proper draining. Installing Leveling Feet
See Figure 2 for installing leveling feet. 1. Lay down a protective pad (pillow, blanket, etc.). 2. Carefully turn unit onto side opposite drain port. 3. Align leveling foot shaft with one of the four threaded hole locations as shown in Figure 2. 4. Screw each leveling foot in ten revolutions. 5. Carefully bring unit to upright position. 6. Level unit for proper water drainage. 7. Wait 10 minutes before operating. CAUTION! Note: Operating the unit immediately after bringing it to an upright position can possibly damage the compressor. A short amount of time is needed (10 minutes) to allow the oil to return to it’s reservoir for lubrication.
4.5 Condensate Water Removal The Quest 150 Dual drains via gravity, therefore, it does not have the ability to push condensate (water) uphill. The drain hose must run downhill toward the drain location. Condensate can be drained by using the 5/8” clear vinyl hose and the 3/4” threaded adapter provided. Ensure the threaded adapter is threaded in tightly. CAUTION! The Quest 150 Dual drains via gravity, therefore, it does not have the ability to push condensate (water) upwards. The drain hose must run down towards the drain location. Condensate can be drained by using the 5/8” clear vinyl hose and the 3/4” threaded adapter provided. Ensure the threaded adapter is threaded in tightly. CAUTION! The Quest 150 Dual requires a drain trap. Creating a drain trap allows a small amount of water to build up in the trap area of the clear hose. This prevents air from back flowing through the hose and into the dehumidifier; essentially causing the unit to backflow water out of the corners of the machine. Position the trap in the hose approximately 8”-10” from the dehumidifier and make sure the highest point of the trap is still at least 2”below the black drain port adapter on the dehumidifier. If the highest point of the trap is above the drain port, water will back flow into the dehumidifier. Check the hose regularly to ensure water is draining properly. Several trap options include: Use care to keep the hose as flat to the floor as possible after your trap is in place. Be sure the hose is not kinked or otherwise restricted so water can pass through the hose freely. Improper installation of the drain hose may result in water leakage. If the Quest 150 Dual is located too far from the floor drain and the provided hose does not reach, you may use a 1/2” PVC rigid pipe to extend the drain. Rigid PVC tubing is readily available from your local hardware store. Be sure the extension is at a down-word slope to the drain.
5. Ducting 5.1 Duct Kit Factory designed duct kits can be purchased to accept 10” ducting to all outlets of the Quest 150 Dual. Contact your dealer or order online. 6. Operation 6.1 Humidity Control Adjustment The humidity control is an adjustable switch that closes when the relative humidity of the air in which it is located rises to the dial set point. It opens when the RH drops 4 to 6% below the set point. Approximate Humidity Levels Per Setting: “Drier” 20% to 30% Relative Humidity “Normal” 45% to 55% Relative Humidity (Recommended) “Humid” 80% to 90% Relative Humidity The dehumidifier will run until the relative humidity (RH) is reduced to the humidity control dial setting. Quality humidity meters are available from the factory and are recommended to accurately monitor humidity levels. Refer to the options and accessories table in this document. 6.2 Fan Switch Turning the impeller switch to “FAN ON” will cause the unit’s internal impeller to run continuously, whether the unit is dehumidifying or not. This function is desirable if the unit is used for air circulation. Turning the fan switch to “FAN AUTO” will cause the unit’s internal blower to run only while the unit is dehumidifying. 7. Maintenance CAUTION! NOTE: 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.
Quest 150 Dual Installation, Operation and Maintenance Instructions 9 www.QuestClimate.com info@QuestClimatecom 7.1 Air Filter The Quest 150 Dual ships with a standard MERV 8 pleated fabric filter. This should be checked every six months. The pleated fabric filter can generally be vacuumed clean several times before needing replacement. Operating the unit with a dirty filter will reduce dehumidifier capacity and efficiency and may cause the compressor to cycle on and off unnecessarily. Replacement filters can be ordered from your dealer or by calling 1-800-533-7533. 8. Service WARNING! Servicing the Quest 150 Dual 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. CAUTION: If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified person in order to avoid a hazard. 8.1 Technical Description The Quest 150 Dual 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 capillary tubing which cause the refrigerant pressure and temperature to drop. It next enters the evaporator coil where it absorbs heat from the incoming air and evaporates.
8.2 Troubleshooting FOR THE USER: If the unit does not work properly, please check the following: — Is the unit unplugged? — Is power to outlet on? (check switch, if applicable) — Is circuit breaker tripped? — Is humidity control set? (turn to “ON”) — Is air flow restricted? (check air filters and grill)
