SAFETY CONSIDERATIONS

Installing and servicing air-conditioning equipment can be haz- ardous due to system pressure and electrical components. Only trained and quali®ed service personnel should install or serv- ice air-conditioning equipment.

When working on air-conditioning equipment, observe pre- cautions in literature and on tags and labels attached to unit.

Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for brazing operations. Have ®re extin- guisher available. Read these instructions thoroughly. Con- sult local building codes and National Electrical Code (NEC) for special installation requirements.

WARNING: Before installing or servicing system, al- ways turn off main power to system. There may be more than one disconnect switch. Electrical shock can cause personal injury.

INSTALLATION

The 575A090 unit uses a semi-hermetic compressor. See Table 1 for physical data.

The 575A090 outdoor unit is approved for use only with the 524A-H090 indoor unit. Use only approved indoor unit.

The 575A090 unit is Underwriters' Laboratories (UL) and UL Canada approved for use with the 524A-H090 indoor unit only.

I.COMPLETE PREINSTALLATION CHECKS A. Uncrate Unit (See Fig. 1)

Remove unit packaging except for the top skid assembly and wood bumpers, which should be left in place until after unit is rigged into place.

B. Inspect Shipment

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

C. Consider System Requirements

·Consult local building codes and NEC for special installa- tion requirements.

·Allow sufficient space for air¯ow clearance, wiring, refrig- erant piping, and servicing unit. See Fig. 2.

·Locate unit so that outdoor unit air¯ow is unrestricted on all sides and above. Refer to Fig. 2.

·Unit may be mounted on a level pad directly on base rails or mounted on raised pads at support points. See Fig. 2 for weight distribution based on recommended support points.

·Provide for condensate drainage and defrost water dis- posal beneath unit.

·Areas with high snowfall may need elevated mounting for adequate air¯ow.

NOTE: If vibration isolators are required for a particular in- stallation, use corner weight information in Fig. 2 to make proper selection.
