SAFETY CONSIDERATIONS

Installing, starting up, and servicing air-conditioning equip- ment can be hazardous due to system pressures, electrical components, and equipment location (roofs, elevated struc- tures, etc.).

Only trained, qualified installers and service mechanics should install, start-up, and service this equipment. Untrained personnel can perform basic maintenance func- tions such as cleaning coils. All other operations should be performed by trained service personnel.

When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment.

Follow all safety codes. Wear safety glasses and work gloves. Keep quenching cloth and fire extinguisher nearby when brazing. Use care in handling, rigging, and setting bulky equipment.

WARNING: Before installing or servicing system, always turn off main power to system and install lock- out tag on disconnect. There may be more than one dis- connect switch. Electrical shock can cause personal injury.

GENERAL

The split system heat pump units described in this book are designed for use with the 524A-H indoor packaged air handler sections only.

INSTALLATION

I. COMPLETE PRE-INSTALLATION CHECKS

A. Uncrate Unit

Remove unit packaging except for the top skid assembly, which should be left in place until after the unit is rigged into its final location.

B. Inspect Shipment

File claim with shipping company if shipment is damaged or incomplete.

C. Consider System Requirements

•Consult local building codes and National Electrical Code (NEC) for special installation requirements.

•Allow sufficient space for airflow clearance, wiring, refrig- erant piping, and servicing unit. See Fig. 1-3 for unit dimensions. Figure 4 shows typical component locations for 541A180 units.

•Locate unit so that outdoor coil airflow is unrestricted on all sides and above.

•Unit may be mounted on a level pad directly on the base channels or mounted on raised pads at support points. See Table 1 for unit operating weights.

II.RIG AND MOUNT UNIT

CAUTION: Be sure unit panels are securely in place prior to rigging. Be careful rigging, handling, and installing unit. Improper unit location can cause sys- tem malfunction and material damage. Inspect base rails for any shipping damage and make sure they are fastened securely to unit before rigging.

A. Rigging

These units are designed for overhead rigging. Refer to rig- ging label for preferred rigging method. Spreader bars are not required if top crating is left on unit. All panels must be in place when rigging. As further protection for coil faces, plywood sheets may be placed against sides of unit, behind cables. Run cables to a central suspension point so that angle from the horizontal is not less than 45 degrees. Raise and set unit down carefully.

If it is necessary to roll the unit into position, mount the unit on field-supplied rails placed lengthwise under the unit, using a minimum of 3 rollers. Apply force to the rails, not the unit. If the unit is to be skidded into position, place it on a large pad and drag it by the pad. Do not apply any force to the unit.

Raise from above to lift unit from the rails or pad when unit is in final position.

After unit in position, remove all shipping materials and top crating.
