Page 4: Intended Application
Quest CDG 174 Installation, Operation and Maintenance Instructions 1. Intended Application for Quest Dual Dehumidifier The Quest Dual Dehumidifier is designed to operate in temperatures between 56° and 95°F. 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. -
Page 5: Transporting
4.3 Electrical Requirements The Quest CDG 174 can be plugged into a grounded 15 Amp circuit. At 80°F, 60% RH, it draws 10 Amps. Due to the high percentage of a 15 Amp circuit’s capacity that the unit uses, the circuit should be dedicated to running it only. Amp draw decreases at lower loads and increases at higher loads. -

The DEFROST light turns on when the unit is in defrost mode indicating when the compressor is off. DRYING TIP: Air’s ability to absorb moisture from wet surroundings and the Quest CDG 174’s ability to remove moisture from that air is greatly improved at higher temperatures. We recommend that the area to be dried be heated to over 70°F if possible. -
Page 7: Maintenance
5.1 Air Filter The Quest CDG 174 is equipped with a pleated fabric air filter that must be checked regularly. The standard filter is a MERV-11 high efficiency filter. Operating the unit with a dirty filter will reduce the dehumidifier’s capacity and efficiency and may cause the compressor to cycle off and on unnecessarily on the defrost control. -
