INSTALLATION

These instructions explain the recommended method of installation of the SA electric cooling unit and associated electrical wiring.

This unit is designed and approved for use as a self- contained air-to-air air conditioning system.

The units are factory equipped with a transformer and blower control for applications without auxiliary heat. Electric heat accessory kits (PHK) can be ordered for field installation of additional heat where required.

These instructions, and any instructions packaged with mating components and/or accessories, should be care-

fully read prior to beginning installation. Note particularly any CAUTIONS or WARNINGS in these instructions and

all labels on the units.

These instructions are intended as a general guide only, for use by qualified personnel and do not supersede any national or local codes in any way. Compliance with all local, state, provincial, or national codes pertaining to this type of equipment should be determined prior to installation.

IMPORTANT:This product has been designed and manufac- tured to meet ENERGY STAR criteria for energy efficiency. However, proper refrigerant charge and proper air flow are critical to achieve rated capacity and efficiency. Installation

of this product should follow the manufacturer’s refrigerant charging and air flow instructions. Failure to confirm proper charge and airflow may reduce energy effi- ciency and shorten equipment life.

Inspection of Shipment

Upon receipt of equipment, carefully inspect it for possible shipping damage. If damage is found, it should be noted on the carrier’s freight bill. Take special care to examine the unit inside the carton if the carton is damaged. File a claim with the transportation company.

If any damages are discovered and reported to the carrier DO NOT INSTALL THE UNIT, as claim may be denied.

Check the unit rating plate to confirm specifications are as ordered.

Limitations

The unit should be installed in accordance with all national and local safety codes.

Limitations of the unit and appropriate accessories must also be observed.

The unit must not be installed with any ductwork in the outdoor air stream. The outdoor fan is not designed to operate against any additional static pressure.

Location

The unit is designed to be located outdoors with sufficient clearance for free entrance to the air inlet and discharge air openings. The location must also allow for adequate service access.

The unit must be installed on a solid foundation that will not settle or shift. Adequate structural support must be pro- vided. Maintain minimum clearances as shown in Figure 1 and Table 1 and install the unit in level position. Isolate the base from the building structure to avoid possible transmis- sion of sound or vibration into the conditioned space.

Sheet Metal

Screw

To avoid possible damage to unit panels from lifting clevis, place packing material between clevis and panels before lifting unit.

Figure 1

Avoid placing the unit near quiet areas such as sleeping quarters or study rooms. Normal operating

sound levels may be objectionable if the unit is placed near certain rooms.

Do not permit overhanging structures or shrubs to obstruct condenser air discharge inlet or outlet.

For improved start-up performance, the indoor coil should be washed with suitable detergent to remove any residue from manufacturing processes.

Exercise care when moving the unit. Do not remove any packaging until the unit is near the place of installation. An accessory lift kit can be purchased to aid in rigging (see

Figure 1). Spreaders whose length exceed the largest dimension across the unit must be used across the top

of the unit. Recommended spreader length: 3 ton and smaller package units – 44", 3.5 ton and larger units – 54".
