ELECTRICAL REQUIREMENT
GENERAL
This INSTALLATION MANUAL briefly outlines where
and how to install the air conditioning system. Please
read over the entire set of instructions for the indoor
and outdoor units and make sure all accessory parts
listed are with the system before beginning.
1. TYPE OF COPPER PIPE AND INSULATION
MATERIAL
Copper tubing for connecting the outdoor unit to the indoor
unit and insulation material is available for purchase locally.
When you purchase them, please specify the following.
(1) Deoxidized annealed copper pipe for refrigerant piping as:
2. ADDITIONAL MATERIALS REQUIRED FOR
INSTALLATION
(1) Refrigeration (armored) tape
(2) Insulated staples or clamps for connecting wire
(See your local electrical codes.)
(3) Putty
(4) Refrigeration lubricant
(5) Clamps or saddles to secure refrigerant piping
Always make the air conditioner power supply a spe-
cial branch circuit and provide a special switch and
receptacle. Do not extend the power cord.
3. OPERATING RANGE
Cut each pipe to the appropriate 12” (30 cm)
to 16” (40 cm) to dampen vibration between units.
(2) Foamed polyethylene insulation for copper pipes as
required to precise length of piping. Wall thickness of
the insulation should not be less than 5/16” (8 mm).
(3) Use insulated copper wire for field wiring.
