Instruction Manual
DRAIN INSTALLATION
The drain outlet on the dehumidifier can be hard piped using a 3/4" PVC Slip x 3/4" MNPT fitting and 3/4" nominal drain tubing or the provided 3/4" 
MNPT x 3/4" hose barb fitting and 3/4" clear PVC tubing can be used to drain the dehumidifier. Always maintain a constant downward slope from the 
dehumidifier to the drain and do not allow soft tubing to curl up which may result in air lock. NOTE: PTFE thread seal tape is recommended for the 
threaded connection and hand tighten only. If hard pipe is used, PVC primer and cement is recommended for the slip fit connection.
LEVELING
The feet can be adjusted to level the unit, and if 
required, to accommodate drain fittings and a 
secondary condensate pan. Leveling is required to 
ensure proper drainage from the dehumidifier. See 
FIGURE 5.
CONDENSATE PAN, CONDENSATE PUMP AND FLOAT SWITCH
A condensate pan is recommended when suspending 
the dehumidifier over the canopy. Adhere to local 
codes regarding draining of the condensate pan. If a 
condensate pump is needed, install it in the condensate 
pan as well. 
Install a condensate overflow safety switch (i.e. float 
switch) in the condensate pan, remove the factory 
installed jumper wire between the Float Switch 
terminals on the control and wire the float switch to the 
dehumidifier as shown in FIGURE 6. Overflow safety 
switches on condensate pumps can be wired to the 
Float Switch terminals in a similar fashion.
