humidity of the space. In most cases, the humidistat and/or dehumidistat should be located near the common
return air grille. Mount the humidistat and dehumidistat at least 18 in from an outside wall and approximately
5 ft above the floor.
Controls may be installed either on a flush switch box or on a surface switch box. Follow the steps below for
mounting. Instructions for wiring the unit are provided in Figures 1622 and section 2.7.6.2.

2.4.7 Spot Water Detector
The spot water detector is normally placed on the floor or in a field-supplied auxiliary drain pan located
beneath the unit.
It may be attached using double sided tape or with the mounting
holes provided in the flanges (one on each side). Once it is in place,
loosen the screws provided on the mounting legs to adjust the
height of the sensing probes. When water is present, current will
flow between the two probes.
CAUTION
The probes must not touch the mounting surface. Failure to
adhere to this may result in improper operation of equipment.
