Installation, Operation and Maintenance Instructions Safety Precautions Read the installation, operation and maintenance instructions carefully before installing and operating this device. Proper adherence to these instructions is essential to obtain maximum benefit from your Quest 110 Dual indoor air quality system. • The device is designed to be installed INDOORS IN A SPACE THAT IS PROTECTED FROM RAIN AND FLOODING. • Install the unit with space to access the back or side panels for maintenance and service. DO NOT INSTALL UNIT WITH THE SERVICE PANELS INACCESSIBLE. • Avoid directing the discharge...

Installation, Operation and Maintenance Instructions 1. Intended Application for Quest 110 Dual The Quest 110 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 110 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...

Installation, Operation and Maintenance Instructions 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 110 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. The Quest 110 Dual can...

Installation, Operation and Maintenance Instructions 4.3 Electrical Requirements The Quest 110 Dual plugs into a common grounded outlet on a 110-120 VAC 15-Amp circuit. While operating, it draws less than 7.2 amps @ 80°F, 60% RH and less than 6.8 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...

Installation, Operation and Maintenance Instructions 4.5 Condensate Water Removal The Quest 110 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 110 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...

Installation, Operation and Maintenance Instructions 5. Ducting 5.1 Duct Kit (P/N 4033039) A factory designed outlet duct kit can be purchased to accept 10” ducting to both outlets of the Quest 110 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...

Installation, Operation and Maintenance Instructions The Quest 110 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 110 Dual with its high pressure refrigerant system and high...

Installation, Operation and Maintenance Instructions 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) If none of the above, call dealer or 1-800-533-7533. FOR THE HVAC PROFESSIONAL: No dehumidification. Neither blower, nor compressor run with fan switch AUTO. 1. Unit unplugged or no power to outlet, circuit breaker tripped. 2. Humidity...
