1.5.2 Coil(s)
The cooling coils and optional hot water reheating coils have aluminum finned and copper tube construction.
The coils are leak tested and cleaned before installation at the factory.
1.5.3 Blower
The unit is equipped with a centrifugal blower with forward curved blades. The blower is contained in a
double-width, double-inlet housing. The blower is dynamically and statically balanced to minimize vibration.
The blower motor is ODP industrial duty and utilizes permanently lubricated ball bearings.
Smaller CeilAir units—models OHS012/040—use direct drive blowers (except H-series models configured
for horizontal discharge). Larger units (models OHS048/120) and horizontal discharge units (models
OHS012/040H), use a belt-driven blower. The belt-driven blower motor is mounted on an adjustable base
for belt tensioning and is furnished with an adjustable pitch sheave to adjust blower speed (see Figure 23 in
section 2.10.5.1).
1.5.4 Temperature Sensor
As a standard for systems utilizing a wall mounted ATech thermostat, the temperature sensor is built into the
thermostat for room air control. The sensor monitors the room air conditions and provides input signal(s) to
the thermostat.
The thermostat manages the operation of the A/C unit consistent with the setpoints entered.
As an option, the temperature sensor may be shipped loose for field installation in the room to be conditioned.
Refer to the electrical drawing supplied with your unit for details specific to your system.
