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 connectin the outdoor unit to the indoor
unit and insulation material is available for purchase locally.
When you purchase them, please specify the following.

ELECTRICAL REQUIREMENT
Always make the air conditioner power supply a special branch cir-
cuit and provide a special switch and receptacle. Do not extend the
power cord.
The following items are necessary to install this air conditioner. (The
items are not included with the air conditioner and must be purchased
separately.)

(TIME DELAY FUSE OR HACR TYPE CIRCUIT BREAKER)
Cut each pipe to the appropriate 12” (30 cm)
to16” (40 cm) to dampen vibration between units.
B. 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).
C. Use insulated copper wire for field wiring.
CAUTION
Check local electrical codes and regulations
before obtaining wire. Also, check any specified
instructions or limitations.
ADDITIONAL CHARGE
Refrigerant suitable for a piping length of 25 ft (7.5 m) is charged in
the outdoor unit at the factory.
When the piping is longer than 25 ft (7.5 m), additional charging is necessary.
For the additional amount, see the table below.

Between 25 ft (7.5 m) and 49 ft (15 m), when using a connection pipe
other than that in the table, charge additional refrigerant with 0.7 OZ/
3.3 ft (20g/1 m) as the criteria.
49 ft (15 m)
5.3 oz (150 g)
CAUTION
(1) When adding refrigerant, add the refrigerant from
the charging port at the completion of work.
(2) The maximum length of the piping is 15 m. If the
units are further apart than this, correct opera-
tion can not be guaranteed.
2. ADDITIONAL MATERIALS REQUIRED FOR INSTALLATION
A. Refrigeration (armored) tape
B. Insulated staples or clamps for connecting wire
(See your local electrical codes.)
C. Putty
D. Refrigeration lubricant
E. Clamps or saddles to secure refrigerant piping
