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" 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� Test all joints to
ensure they are leak free before completing the installation�
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 7�
CONDENSATE PAN, CONDENSATE PUMP AND FLOAT SWITCH
A condensate pan is recommended when suspending
the dehumidifier over finished areas or product� 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 8� Overflow safety
switches on condensate pumps can be wired to the
Float Switch terminals in a similar fashion�
