Mounting
CeilAir TR-OHS systems are designed for ceiling mounting
in a suspended ceiling grid (spot cooler) or above the
Figure 6.
Typical installation
Notes: Do not install the A/C system directly above
electronic equipment that may hinder
serviceability. Equipment must be level to
operate properly.
Indoor Equipment
CeilAir TR-OHS systems have a frame and panel
construction for unit rigidity and full service accessibility
while the unit is mounted in place. The unit is lifted from
underneath and secured into place using all-thread rods
passing through rubber grommets or a 4 in. x 4 in.
neoprene cork pad in the mounting arms on the sides of
the unit. Threaded rods, nuts and washers (field supplied
by others) must be secured so they do not loosen. (See
Figure 6, p.
13.)
Before mounting the unit, ensure the mounting structure
is able to support the weight of the equipment. Refer to the
weight table provided on the installation drawing. Secure
the unit via the pre-drilled mounting bolt holes with
suitable hardware for the application. An auxiliary drain
pan is recommended and can be mounted directly under
the cabinet (only on ducted models; see
Outdoor Equipment
Install remote condensers/condensing units in a secure
location where the unit cannot be tampered with and the
power service switch cannot be inadvertently turned off.
Locate the remote condenser/condensing unit where the
fan is not likely to draw dirt and debris into the coil fins.
There should be at least one equipment-width of clearance
around the condenser to ensure adequate airflow to the
coil. Secure the condenser/condensing unit so the system
will not move during operation. Refer to the installation
drawing for the non-charged system weight. It is

recommended that the remote condenser/condensing
unit be mounted with vibration mounts to reduce the
amount of vibration transmitted to the mounting surface.
Controls
Note: Thermostats and control sensors should not be
located near a doorway, supply air register or area
where they would be exposed to direct sunlight or
other external heat sources.
A-Tech Programmable Thermostats
Mount the thermostat upright on an inside wall within the
conditioned room at a location that best represents the
average room temperature. In most cases, the thermostat
should be located near the common return air grille and
kept away from direct sunlight. Mount the thermostat at
least 18 in. from an outside wall and approximately 5 ft
above the floor. Follow the steps below for mounting.
Instructions for wiring the thermostat are found in Section
"A-Tech 1.1 Programmable Thermostat," p. 22
1.2 Programmable Thermostat," p.
1. Open the case with a flathead screwdriver. Place blade
in slot and gently pry forward at the numbered
locations shown in the below figure.
