Use the main control knob (Figure 2) on the outside of the unit
to set the dehumidifier dryness setting. Start with a “NORMAL”
setting for most installations. Moving the knob clockwise to
“MORE” will make conditions drier. Moving the knob toward
“LESS” allows for higher moisture levels.
Based on the indoor temperature, use the following table to
determine the control knob setting to reach the desired RH value.
The dehumidifier will work to achieve these values.
EXAMPLE: At an indoor temperature of
75°F with a dehumidifier control knob
setting of 3, the dehumidifier will work to
achieve an RH value of 53%.
NOTES:
1. %RH values are ±5% and are to be
used as a GUIDE ONLY for initial
set-up.
2. Indoor Temperature is measured at the
inlet to the dehumidifier.
1. Install the drain line
NOTE: The provided condensate trap must be installed to the dehumidifier.

IMPORTANT: The bottom of the trap outlet must be at least
1

dehumidifier to ensure a proper drainage slope (see Figure 1).

/2 inch I.D. drain hose.
Route the hose to the nearest drain.
IMPORTANT: To prevent a pressure lock within the drain line, the tube MUST be installed with a
constant downward slope.
Prime the drain system by filling the drip pan in the dehumidifier with water until flow is completed to
the drain.
2. Plug the dehumidifier directly into an outlet – DO NOT USE AN EXTENSION CORD.
NOTE: A 15 amp circuit is required for proper operation.
3. Turn the ON/OFF switch to ON.
