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. At extremely high loads, a 20 Amp circuit may be required.
If an extension cord is required, it must have a minimum of 12 gauge conductors if 25 feet long or less and 10 gauge
conductors if greater than 25 feet long.
2.4 Condensate Removal
The Quest CDG 174 is equipped with an internal condensate pump to remove the water that is condensed during
dehumidification. This allows the condensate to be pumped 30’ with the attached hose. If the condensate must be
pumped more than 20 feet above the unit, a second pump must be added to relay the condensate.
2.5 Ducting
A detachable rectangular exhaust collar is supplied that will allow 10” round lay-flat duct to be attached to the Quest
CDG 174 outlet.
To attach ducting to a collar, put the plastic duct end through the collar center and roll the duct end outward so that it
overlaps the outside of the collar. The duct and collar may then be quickly attached to the Quest CDG 174 by snapping
the collar over the four screws at the blower outlet.
2.6 Power Button
Press the POWER button to turn the dehumidifier on or off. When starting the dehumidifier the display will show the
accumulated hours. Press the POWER button again to turn the dehumidifier off. The display will also power off.
2.7 Pump Purge Button
During normal operation the pump automatically cycles every four minutes. Press the PURGE button to remove
condensate manually from the reservoir. There are several ways to manually remove water from the reservoir:
1. Press the PURGE button once and the pump will run for 20 seconds
2. Press and hold the PURGE button and the pump will run for up to 30 seconds
3. Press the PURGE button while the dehumidifier is powered off and the pump will run for 30 seconds.
Always manually purge the water reservoir before transport or storage. Turn off the power and allow the plugged in dehu-
midifier to rest 15 minutes before the final purge.
2.8 Humidistat
Adjust the humidistat to the desired conditioned humidity. The humidistat has a range of 20% to 70% RH. “ON” will
operate the unit continuously regardless of humidity.
2.9 Hours Button
Pressing the HOURS button displays the hour meter when the unit is turned off but plugged into power. To reset job
hours, press and hold the HOURS button for 5 seconds when the unit is operating.
