SAFETY CONSIDERATIONS
Installing, starting up, and servicing air-conditioning equip-
ment can be hazardous due to system pressures, electrical
components, and equipment location (roofs, elevated struc-
tures, etc.).
Only trained, qualified installers and service mechanics
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
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.
GENERAL
System Requirements
• Consult local building codes and National Electrical
Code (NEC, U.S.A.) for special installation requirements.
• 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, 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
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.
Before installing or servicing system, always turn off main
power to system and install lockout tag on disconnect.
There may be more than one disconnect switch. Electrical
shock can cause personal injury.
IMPORTANT:
The Indoor unit & the inter units cable voltage
is 30 VDC
IMPORTANT:
Each
refrigerant line must be insulated
separately.
See line sizing requirements in table 2.
Do not bury more than 36 in. of refrigerant pipe in the
ground. 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 recommended length is buried,
refrigerant may migrate to the cooler buried section during
extended periods of system shutdown. This causes refriger-
ant slugging and could possibly damage the compressor at
start-up.
