SAFETY CONSIDERATIONS

Installing and servicing air-conditioning equipment can be haz-

ardous due to system pressure and electrical components. Only

trained and qualiﬁed 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 ﬁre extin-

guisher available. Read these instructions thoroughly. Con-

sult local building codes and National Electrical Code (NEC)

for special installation requirements.

Before installing or servicing system, al-

ways turn off main power to system. There may be more

wood bumpers, which should be left in place until after unit

is rigged into place.

B. Inspect Shipment

incomplete.

C. Consider System Requirements

• Consult local building codes and NEC for special installa-

tion requirements.

• Allow sufficient space for airﬂow clearance, wiring, refrig-

erant piping, and servicing unit. See Fig. 2.

• Locate unit so that outdoor unit airﬂow 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 airﬂow.

NOTE: If vibration isolators are required for a particular in-

stallation, use corner weight information in Fig. 2 to make

proper selection.
