LEVELING
The feet can be adjusted to level the unit, and if required,
to accommodate drain ttings and a secondary condensate
pan. Leveling is required to ensure proper drainage from
the dehumidier. See Figure 9.
Drain Installation
The drain outlet on the dehumidier can be hard piped
using a 3/4" PVC Slip x 3/4" MNPT tting and 3/4" nominal
drain tubing or the provided 3/4" MNPT x 3/4" hose barb
tting and 3/4" clear PVC tubing can be used to drain
the dehumidier. Always maintain a constant downward
slope from the dehumidier 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 t
connection.
CONDENSATE PAN, CONDENSATE PUMP
AND FLOAT SWITCH
Always install the dehumidier in a condensate pan when
locating in or above a nished 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 overow safety switch (i.e. oat switch)
in the condensate pan, remove the factory installed jumper
wire between the Float Switch terminals on the control and
wire the oat switch to the dehumidier as shown in Figure
10. Overow 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 dehumidier base. See Figure
8. Do not position threaded rods over lter 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 lter.
