2.3 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. -

3.1 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. -
