GENERAL

The outdoor units are completely piped and wired at the factory 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, evacuated, leak tested and pressure tested at 450 psig before being 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. After 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 suction 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 vertically 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 distributors 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 wiring (Power and Control) can be made through the front of the unit.

2Below 0 °F, the control circuit will lock out the compressor and allow the electric heat accessory to cycle at its standby capacity.

These beams can usually be set directly on the roof. Flashing is not required.

NOTE: On bonded roofs, check for special installation requirements.

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 refrigerant leak. Aone-piece concrete slab with footers that extend below the frost line is recommended. The slab should not be tied to the building foundation because noise and vibration will telegraph.

A unit can also be supported by concrete piers. These piers should: (1) extend below the frost line, (2) be located under the 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.

A gravel bed or some other means of handling the condensate that will drop from the underside of the unit coil during the heating and defrost cycles may have to be provided.

LOCATION

Use the following guidelines to select a suitable location for these units.

1.The outdoor units must be installed outside the building. The outdoor fans are the propeller type and are not suitable for use with duct work.

	20 Ton	16	38

WARNING: The outdoor unit should not be installed in an area where mud and/or ice could cause personal injury. Remember that condensate will drip from the underside of the unit coils during heat and defrost cycles and that this condensate will freeze when the temperature of the outdoor air is below 32°F.

4.All units require certain clearances for proper operation and service.

On either rooftop or ground level installations, rubber padding can be applied between the base rails and their supports to lessen any transmission of vibration.

ROOF-TOP LOCATIONS

Be careful not to damage the roof. Consult the building contractor or architect if the roof is bonded. Choose a location with adequate structural strength to support the unit.

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

A minimum of two (2) beams are required to support each unit. The beams should: (1) Be positioned perpendicular to the roof joists. (2) Extend beyond the dimensions of the unit to distribute the load on the roof, (3) Be capable of adequately supporting the entire unit weight. Refer to Figure 1 and Table 2 for load distribution and weights.

FIG. 1 - CENTER OF GRAVITY

CAUTION: Care should be taken to protect the unit from tampering and unauthorized persons from injury. Screws on access panels will prevent casual tampering. Additional safety precautions such as fences around the unit or locking devices on the panels may be advisable. Check local authorities for safety regulations.

RIGGING AND HANDLING

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

Rig the unit by attaching chain or cable slings with hooks to the round lifting holes provided in the base rails.

CAUTION: Spreaders, longer than the largest dimension across the unit, MUST be used across the top of the unit. See Figure 2.

WARNING: BEFORE LIFTING A UNIT, MAKE SURE THAT ITS WEIGHT IS DISTRIBUTED EQUALLY ON THE CABLES SO THAT IT WILL LIFT EVENLY.

Units may also be moved or lifted with a fork-lift from the front, rear or the compressor end only through the slotted openings provided in the base rails.

035-16192-001-A-1001

CAUTION: LENGTH OF FORKS MUST BE A MINIMUM OF 54" (when lifting from the compressor end of the unit) and a MINIMUM OF 42" (when lifting from the 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

All units require certain minimum clearances for proper operation 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 prevent refrigerant from mixing with crankcase oil during the “OFF” cycle. The heaters will be energized when the compressor is not running providing the unit disconnect switch is closed.

FIG. 2 - TYPICAL RIGGING

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 required to drive the liquid refrigerant out of the compressor before the compressor can be started.

POWER AND CONTROL WIRING

Install electrical wiring in accordance with the latest National Electrical Code (NFPA Standard 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 disconnect 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 terminal block TB2 of the unit control box through this access opening 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
