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 ventilator.
See Figure 5.
The drain outlet on the ventilator can be hard piped using 3/4” nominal drain tubing or the provided fitting and 1/2” clear PVC tubing can be used
to drain the ventilator. Always maintain a constant downward slope from the ventilator to the drain and do not allow soft tubing to curl up which
may result in air lock. NOTE: Always use PVC primer and cement when connecting PVC drain line or the provided fitting to the dehumidifier drain
outlet.
Always install the ventilator 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 ventilator as shown in Figure 6. Overflow safety
switches on condensate pumps can be wired to the
Float Switch terminals in a similar fashion.
