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.

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 10. Overflow
safety switches on condensate pumps can be wired
to the Float Switch terminals in a similar fashion.
