SAFETY CONSIDERATIONS

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

can be hazardous due to system pressures, electrical components,

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 perform basic maintenance functions 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.

Read these instructions thoroughly and follow all warnings or

cautions included in literature and attached to the unit. Consult

local building codes and current editions of the National Electrical

Code ( NEC ) NFPA 70. In Canada, refer to current editions of the

Canadian electrical code CSA 22.1.

Recognize safety information. This is the safety--alert symbol

When you see this symbol on the unit and in instructions or

manuals, be alert to the potential for personal injury.Understand

these signal words: DANGER, WARNING, and CAUTION.

These words are used with the safety--alert symbol. DANGER

identifies the most serious hazards which will result in severe

personal injury or death. WARNING signifies hazards which

could result in personal injury or death. CAUTION is used to

identify unsafe practices which may result in minor personal injury

or product and property damage. NOTE is used to highlight

suggestions which will result in enhanced installation, reliability, or

operation.

WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal

injury or death.

Before installing, modifying, or servicing system, main

electrical disconnect switch must be in the OFF

position. There may be more than 1 disconnect switch.

Lock out and tag switch with a suitable warning label.

CAUTION

EQUIPMENT DAMAGE HAZARD

Failure to follow this caution may result in equipment

damage or improper operation.

Do not bury more than 36 in. (914 mm) of refrigerant pipe

in the ground. If any section of pipe is buried, there must be

a 6 in. (152 mm) 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 shutdown. This causes

refrigerant slugging and could possibly damage the

compressor at start--up.

GENERAL

These instructions cover the installation, start--up and servicing of

the 38GVM outdoor unit connected to up to four 40GVM indoor

high wall units. For approved combinations, please refer to the

Product Data.

SYSTEM REQUIREMENTS

Allow sufficient space for airflow and servicing unit. See Fig. 7

through 9 for minimum required clearances.

Piping

IMPORTANT: Both refrigerant lines must be insulated

separately.

Minimum refrigerant line length between the indoor and outdoor

units is 10 ft. (3 m).
