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 9
.
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.
CONDENSATE PAN, CONDENSATE PUMP
AND FLOAT SWITCH
Always install the dehumidifier in a condensate pan when
locating in or above a finished space. 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
10
. Overflow safety switches on condensate pumps can
be wired to the Float Switch terminals in a similar fashion.

Suspended Installation
If hanging the unit, use 1/4" (minimum) threaded rod and
two unistruts to support the base, just inside the leveling
feet. It is recommended that vibration isolators be placed
between the unistruts and dehumidifier base. See
Figure
8
. Do not position threaded rods over filter access doors.
Allow 3" between the unit and threaded rods on the service
access to remove the side panel if service is required. There
must be a minimum clearance of 12" on one side of the
unit to allow for removal of the filter.
