Care must be taken to avoid secondary damage due to over-
drying.
2.3 Universal Use Set-Up
When conditions warrant the use of a desiccant dehumidifier,
use the set-up shown below (Fig. 3). This universal set-up will
produce efficient drying, while avoiding secondary damage.
The Quest PowerDry 385D Pro has been designed with the
goal of being easy to use every time.
The Quest PowerDry 385D Pro comes complete and can be
plugged in and turned on. Connected this way, the Quest
PowerDry 385D Pro will run continuously.
Note: Check for airflow at all inlets and outlets. DO NOT run unit if no airflow is
detected.
2.4 Location
Note the following precautions when locating the Quest PowerDry 385D Pro:
• It is designed to be used INDOORS ONLY.
• If used on a water loss work site, plug it into GROUND FAULT CIRCUIT INTERRUPT (GFCI) OUTLETS
• The air inlet on top and the side outlet must be at least
1 foot from walls and other air flow obstructions.
• If the humid area is very large, dehumidification can be improved by adding an outlet duct to circulate process air to
stagnant areas.
• DO NOT use the Quest PowerDry 385D Pro as a bench or table.
2.5 Electrical Requirements
When used on a water loss work site, ground fault circuit interrupter (GFCI) outlets are required.
Your Quest PowerDry 385D Pro requires a total of 22 amps, 115VAC. In order to run at all, this machine must be
plugged into two separate circuits each with a minimum of 11 amps dedicated capacity available.
The PowerDry 385D Pro has two separate power cords, each cord must be plugged into its own 15 amp circuit. If both
cords are plugged into the same 15 amp circuit this circuit will trip when the unit is turned on.
Another situation to avoid is that one or both of the circuits which the PowerDry 385D Pro is using can be tripped by
other appliances drawing power from either circuit. This can happen well after a job site has been set-up as in the case
with a freezer compressor turning on.
Care must be taken to insure that the PowerDry 385D Pro always has sufficient power available to run without tripping
breakers or blowing fuses.
