CLEARANCES

All units require certain minimum clearances for proper opera-
tion and service. Refer to Figure 4 for these clearances.

WARNING: Do not permit overhanging structures or shrubs to

obstruct condenser air discharge.

Additional height may be required for snow clearance if winter
operation is expected.

POWER AND CONTROL WIRING

Install electrical wiring in accordance with the applicable na-
tional, local and municipal codes. The unit should be grounded
in accordance with these codes.

POWER WIRING

Check the voltage of the power supply against the data on the
unit nameplate. Check the size of the power wire, the discon-
nect switch and the fuses against the data in Table 3.

NOTE: Copper conductors must be installed between the dis-

connect switch and the unit.

Refer to Figure 4 for the location of the power wire access
opening through the front of the unit. This opening will require a
field-supplied conduit fitting.

The field-supplied disconnect switch must be suitable for an
outdoor location. Although it should be installed near the unit,
do NOT secure it to the unit cabinet.

Refer to Figure 3 for typical field wiring.

CONTROL WIRING

Refer to Figure 4 for the location of the control wire access
opening through the front of the unit.

Route the necessary low voltage control wires from the TB1
terminal block inside of the unit control box through this access
opening to the room thermostat and to the evaporator blower
motor controller. Wires #18 AWG (1.0mm

2

) should be used.

The room thermostat should be located on an inside wall ap-
proximately 56" (1420mm) above the floor where it will not be
subject to drafts, sun exposure or heat from electrical fixtures
or appliances. Follow manufacturer's instructions enclosed
with thermostat for general installation procedure.

Refer to Figure 3 for typical field wiring.

COMPRESSOR

Units are shipped with compressor mountings factory-adjusted
and ready for operation.

CAUTION: Do Not loosen compressor mounting bolts.

COMPRESSOR CRANKCASE HEATER

The compressor is equipped with a crankcase heater to pre-
vent refrigerant from mixing with crankcase oil during the
“OFF” cycle. The heaters will be energized when the compres-
sor is not running providing the unit disconnect switch is
closed.

CAUTION: Do not attempt to start the compressor without at

least eight hours of crankcase heat or compressor
damage will occur.

If a unit has just been installed or the unit disconnect switch has
been open for a long period of time, move the system switch on
the room thermostat to the “OFF” position before closing the
unit disconnect switch. Eight hours of crankcase heat are re-
quired to drive the liquid refrigerant out of the compressor bef-
ore the compressor can be started.
