A level surface is required to ensure proper drainage from the dehumidifier.
The drain outlet on the dehumidifier can be hard piped using 3/4” nominal drain tubing or the provided fittings and 1/2” 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.
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 4
. Overflow safety switches
on condensate pumps can be wired to the Float Switch terminals in
a similar fashion.
