ELECTRICAL REQUIREMENT
GENERAL
This INSTALLATION INSTRUCTION SHEET 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 pur-
chase locally. When you purchase them, please speci-
fy 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.

(1) Limit the height difference between
the indoor and outdoor units to
within 26 ft. (8 m).
(2) The maximum length of the piping
is 66 ft. (20 m). If the units are fur-
ther apart than this, correct opera-
tion can not be guaranteed.
