GENERAL

These condensing units are designed for outdoor installation on a roof or at ground level. Every unit is completely piped and wired at the factory and is shipped ready for immediate installation. Only the liquid and suction lines to the evaporator coil, the control wiring and the main power wiring are required to complete the installation. Each 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.

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.

Refer to Table 7 for condenser cooling capacities and power requirements.

REFERENCE

This instruction covers the installation and operation of the basic condensing unit. For information on the installation and operation of the evaporator blower units, please refer to the matching air handler installation manual.

INSTALLATION

LIMITATIONS

These units must be installed in accordance with all national and local safety codes. If no local codes apply, installation must conform with the appropriate national codes. See Table 1 for Unit Application Data. Units are designed to meet National Safety Code Standards. If components are to be added to a unit to meet local codes, they are to be installed at the dealer's and/or the customer's expense.

2These units can operate at an ambient temperature of 120°F providing the wet bulb temperature of the air entering the evaporator coil does not exceed 67°F.

NOTE: Refer to page 7 for refrigerant piping limitations.

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

1.The condensing unit is designed for outdoor installation only. The condenser fans are the propeller type and are not suitable for use with duct work.

2.The condensing unit and the evaporator blower should be installed as close together as possible and with a minimum number of bends in the refrigerant piping. Refer to “REFRIGERANT PIPING” for additional information.

3.The condensing unit should not be installed where normal operating sounds may be objectionable. 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 condensing 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 Center of Gravity and Point Load Figures and Physical Data Table for load distribution and weights.

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 one-piece level concrete slab with a minimum thickness of 4 inches. The length and width should be at least 6 inches greater than the units overall base dimensions. Refer to Figure 4.

Footers under the slab that extend below the frost line is recommended. Any strain on the refrigerant lines may cause a refrigerant leak. The slab should not be tied to the building foundation because noise and vibration will telegraph into your structure.

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.

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.

FIG. 1 - CENTER OF GRAVITY

Rig the unit by attaching nylon straps with hooks to the lifting holes provided in the base rails. Spreaders, whose length exceeds the largest dimension across the unit, MUST be used across the top of the unit if the rigging height above the top of the unit is less than 5 feet. See Figure 2.

WARNING:Do not use straps under the unit or through the fork lift slots for lifting purposes. Sharp metal edges can damage the straps and could result in personal injury or equipment damage.

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

Units may also be moved or lifted with a fork-lift. Slotted openings in the base rails are provided for this purpose. The 7-1/2 ton unit may be lifted from either the LH or RH side - under the unit.

LENGTH OF FORKS MUSTBE AMINIMUM OF 42" for 7-1/2 ton units or a MINIMUM OF 54" for 10 ton units when lifting across the long dimension.

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.

FIG. 2 - TYPICAL RIGGING (7-1/2 Ton Shown)

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 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 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 on Table 3.

NOTE: Copper conductors must be installed between the disconnect switch and the unit.

TABLE 2 - PHYSICAL DATA

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 (18 AWG min.) 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.

The room thermostat should be located on an inside wall approximately 56" 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 factoryadjusted and ready for operation.

CAUTION: Do Not loosen compressor mounting bolts.

COMPRESSOR CRANKCASE HEATER (7-1/2 & 10 ton units only)

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.

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