CAUTION
The probes must not touch the mounting surface.
Failure to adhere to this may result in improper
operation of equipment.
2.4.5.4 Cable Type Water Detector
Lay the cable water detector across the surface where
water could collect.
When water is
present, current will
flow between the two
wires.
2.5 Air Distribution Connection
2.5.1 Spot Cooler (See Figure 2)
For units that are not ducted, the air conditioner should
be mounted above the ceiling grid, leaving sufficient
space for the air grilles to rest on the ceiling T-bar.
NOTE
Placement of the grilles is important. The hinged
filter grille goes on the return air side of the unit.
The 3-way directional grille goes on the condi-
tioned air discharge side of the air conditioner.
Gasketing is factory supplied for an air seal be-
tween the bottom flange of the air conditioner
and the grille. After mounting the air conditioner,
lower the air conditioner until the gasket meets
the grille.
