NOTE: Filter racks need a 26" minimum clearance at front of unit
for removal of filters. See chart below if unit is going to be placed
near combustible construction or materials.
While minimum
clearances
are acceptable
for safety reasons,
they may not allow adequate
air circulation
around the unit for
proper operation in the cooling mode. Whenever
possible, it is desirable to allow additional
clearance,
especially
around the condenser inlet and discharge

4. Gas Supply and Piping
Because there are many types of liquefied petroleum
(LP) gases,
the term LP as used in this manual refers to propane gas. If you
intend to use any type of LP gas, proper precautions
MUST be
used in the handling, piping, and use ofsuch gas. NOTE: In Canada, LP installations
MUST be performed
by licensed LP installers.
The Rating Plate located on the side panel on the unit contains the
model number, type of gas and gas input rating, and other important information.

Gas Piping
The gas supply line MUST be of adequate
size to handle the Btu/
hr requirements
and length of the run for the unit being installed.
Determine
the minimum pipe size for natural gas from the table in
Figure 8 & Figure 9. Base the length of the run from the gas meter
or source to the unit.

Btu ratings of all other gas appliances
MUST be considered

and in Canada the

Make certain the unit is equipped to operate on the type
of gas available. Models designated as natural gas are
to be used with natural gas only. Models designated for
use with liquefied petroleum (LP) gas are shipped with
orifices sized for commercially pure propane gas. They
MUST not be used with butane or a mixture of butane
and propane unless properly sized orifices are installed
by a licensed LP installer.

The economizer
is controlled
by a logic module which field connects to the unit controls through a plug harness. The logic module also controls the compressor
staging based on the thermostat
input.
The minimum

is field

economizers
or on the actuator motor of three-position
economizers.
The enthalpy
sensor is factory installed on the fresh air dampers
of the economizer.
The enthalpy change-over
point is adjustable
on the logic module.
A discharge
air sensor is field installed in the blower inlet. The discharge air sensor keeps the discharge
air above 56°F (13.3°C).
A positive pressure is created when the fresh air dampers open
and the return dampers close. This pressure
must be vented or
the air will not circulate properly. This is the function of the barometric relief dampers. A positive pressure forces the passive exhaust dampers
to swing open.

Controls

and Features

High and low pressure switches are provided on these units which
will shut down the system when high pressures exceed 420 psi
and low system pressures fall below 27 psi. The switches automatically reset after a fault. They are accessed through the compressor compartment access panel.

Fan Cycle Pressure Switch Port (optional)
If your unit will be operated in low ambient conditions

Cooling Time Delay Relay (Not All Models)

Freeze Protection Thermostat (Not All Models)

A cooling time delay relay is used on the evaporator blower motor
to increase efficiency (SEER). On a call for cooling, the blower
motor starting is delayed for 30 seconds. Also, after the thermostat is satisfied, the blower motor continues to run for 30 seconds
after the condenser fan motor and compressor have shut off.

The freeze protection thermostat
