I IMPORTANT: Both refiigerant lines must be insu- I

lated separately.

• Consult local building codes and National Electrical

Code (NEC, U.S.A.) for special installation requirements.

• Control wiring should be 18 gage.

• Use only type "G" or"C" fuses.

• Use single length power cable without extension.

• Allow sufficient space for airflow clearance on condens-

ing units for wiring, refiigerant piping, and servicing

unit. See Fig. 1 and 2 for minimum required distances

between unit and walls or ceilings.

• Indoor and outdoor units should be installed at a mini-

mum of 10 It apart. Maximum line length is 130 It, and

vertical separation is 66 It.

• Do not install indoor units near a direct source of heat

such as direct sunlight, steam or flame.

SAFETY CONSIDERATIONS

Installing, starting up, and servicing air-conditioning equip-

ment can be haz_udous due to system pressures, electrical com-

ponents, and equipment location (roofs, elevated structures, etc.).

Only trained, qualified installers and service mechanics

should install, start-up, and service this equipment.

Untrained personnel can pet-form 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 zdlsafety codes. We_u safety glasses and work gloves.

Keep quenching cloth and fire extinguisher ne_uby when braz-

ing. Use care in handling, rigging, and setting bulky equipment.

Before installing or servicing system, _dways turn off main

power to system and inst_dl lockout tag on disconnect.

There may be more than one disconnect switch. Electric_d

shock can cause personal injury.

GENERAL

These instructions cover the installation, st_u-t-upand set-,de-

ing of 38BNB,BNE036 outdoor and 40BNB,BNE036 indoor

units cooling only and heat pump duct fi'ee systems. See Table 1

for paris included. See Tables 2 and 3 for Physical Data.

System Requirements

I IMPORTANT: See line sizing requirements in Tables 2

and 3.

Do not bury more than 36 in. of refi'igerant pipe in the

ground, ff any section of pipe is buried, there must be a

6 in. vertical rise to the valve connections on the outdoor

units. If more than the recommended length is buried,

refrigerant may migrate to the cooler buried section during

extended periods of system shut down. This causes refrig-

erant slugging and could possibly &image the compressor

at start-up.
