GENERAL

The outdoor units are completely piped and wired at the fac-

tory and are shipped ready for immediate installation. Only

the interconnecting liquid and suction lines, sight glasses,

control wiring, and the main power wiring are required to

complete the installation. Every unit is dehydrated, evacu

ated, leak tested and pressure tested at 450 psig before be

ing pressurized with a holding charge of refrigerant-22 for

shipment and/or storage.

To eliminate the costly cabinet deterioration problems usually

associated with outdoor equipment, all sheet metal parts are

constructed of commercial grade (G90) galvanized steel. Af

ter fabrication, each part is thoroughly cleaned to remove

any grease or dirt from its surfaces. The parts that will be

exposed to the weather are then coated with a “desert sand”

powder paint to assure a quality finish for many years. This coating system has passed the 750-hour, salt spray test per

ASTM Standard B117.

Every unit includes 2 heavy-duty scroll compressors, 2 suc

tion line accumulators, 2 4-way reversing valves with a 24

volt solenoid, 2 outdoor fan motors with inherent protection,

and a copper tube/aluminum fin coil that is positioned verti

cally for better drainage of the water that will condense on it

during the heating cycle.

They also include 2 filter driers, 2 expansion valves and dis

tributors that are only used during the heating cycle plus a

check valve to provide the proper flow of refrigerant through

the unit during both the cooling and heating cycles.

All controls are located in the front of the unit and are readily accessible for maintenance, adjustment and service. All wir-

ing (Power and Control) can be made through the front of

the unit.

INSPECTION

As soon as a unit is received, it should be inspected for pos

sible damage during transit. If damage is evident, the extent of the damage should be noted on the carrier's freight bill. A separate request for inspection by the carrier's agent should

be made in writing.

LOCATION

Use the following guidelines to select a suitable location for

GROUND LEVEL LOCATIONS

The units must be installed on a substantial base that will not settle. Any strain on the refrigerant lines may cause a refriger antleak. Aone-piececoncrete slabwith footersthat extendbe low the frost line is recommended. The slab should not be tied tothe buildingfoundation becausenoise and vibrationwill tele graph.

A unit can also be supported by concrete piers. These piers should:(1) extend below the frostline, (2) be located underthe unit's four corners and (3) be sized to carry the entire unit weight. Refer to Figure 1 and Table 2 for the center of gravity and unit weight.

Agravel bed or some other means of handling the condensate thatwill drop fromthe underside ofthe unit coil duringthe heat ing and defrost cycles may have to be provided.

The unit must be mounted on solid level supports. The sup ports can be channel iron beams or wooden beams treated to reduce deterioration.

Aminimum of two (2) beams are required to support each unit. The beams should: (1) Be positioned perpendicular to the roof

RIGGING AND HANDLING

Exercise care when moving the unit. Do not remove any pack aging until the unit is near the place of installation.

CAUTION: LENGTH OF FORKS MUST BE A MINIMUM OF

54" (when lifting from the compressor end of the unit)and a MINIMUMOF 42"(when lifting fromthe front or rear of the unit).

Remove the nesting brackets from the four corners on top of the unit. All screws that are removed to take these brackets off must be replaced on the unit.

CLEARANCES

5 ft.

MIN

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 air discharge.

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

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 com

pressor is not running providing the unit disconnect switch is

closed.

Eight hours of crankcase heat are re quired to drive the liquid refrigerant out of the compressor bef ore the compressor can be started.

POWER AND CONTROL WIRING

Install electrical wiring in accordance with the latest National Electrical Code (NFPAStandard No. 70) and/or local regulations. 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

disconnect 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 re

quire 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 terminal

block TB2 of the unit control box through this access open

ing to the indoor unit and to the room thermostat. Refer to

Figure 3 for typical field wiring.

The room thermostat should be mounted about 5 feet above

the floor and located where it will be exposed to normal room

air circulation. Do not locate it on an outside wall, near a

supply air grille, or where it may be affected by sunlight
