SAFETY CONSIDERATIONS

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

ment can be hazardous due to system pressures, electrical compo-

nents, and equipment location (root;, elevated structures, etc.).

Only trained, qualified installers and selaTicemechanics 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 per-

formed by trained service personnel.

When working on the equipment, observe precautions in the

literature and on tags, stickers, and labels attached to the equip-

ment.

Follow all safety codes. Wear safety glasses and work gloves.

Keep quenching cloth and fire extinmaisher nearby when brazing.

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

Before installing or servicing system, always turn offmain power

to system and install lockout tag on disconnect. There may be

more than one disconnect switch. Electrical shock can cause

personal injury.

GENERAL

These instructions cover the installation, start-up and sela_ic-

ing of 38BCC/BCQ outdoor and 40BNC/BNQ indoor units cool-

ing only and heat pump duct free systems. See Table 1 for parts

included. See Tables 2 and 3 t\_r Physical Data.

System Requirements

IMPORTANT: The Indoor units & the inter units cable

voltage is 30 VDC.

IMPORTANT: Each refrigerant line must be insulated

Separately. See line sizing requirements in tabel 2.

Consult local building codes and National Electrical Code

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

Max. cable length. Total voltage drop should not exceed 1V.

Therefore max. length:

For #18 AWG 24.3 Feet (7.4 m)

For #16 AWG 37.7 Feet (11.5 m)

For #14 AWG 50.0 Feet (18 m)

Use only type "G" or "C" fuses. Use single length power

cable without extension. Allow sufficient space for airflow

clearance on condensing units for wiring, refrigerant 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

Minimum length of 10 ft. apart.

Maximum line length of 50 ft. and

vertical separation of 30 ft.

Do not install indoor units near a direct source of heat such as

direct sunlight, steam or flame.

Do not bury more than 36 in. of refrigerant pipe in the _ound. If

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 rec-

omlnended length is buried, refrigerant may mira'ate to the cooler

buried section during extended periods of systeln shutdown. This

causes refiiger-ant slugging and could possibly damage the com-

pressor at start-up.

Indoor Units START-UP System Checks 1. Conceal the tubing where possible. To avoid the possibility of electric shock, bet\_re performing any cleaning and maintenance operations, always turn offpower to the system by pressing the ON/OFF button on the remote control and turn off the separate disconnect switch located near the unit. If the indoor unit is on a separate switch, be sure to turn this disconnect off as well. 2. Make sure that the drainage tube slopes downward along its entire length. 3.
