Always select the size that corresponds to the capacity of the breaker to
the size of 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.)

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.
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
3. OPERATING RANGE

ADDITIONAL CHARGE
Refrigerant suitable for a piping length of 49 ft (15 m) is charged in
the outdoor unit at the factory.
When the piping is longer than 49 ft (15 m), additional charging is necessary.
For the additional amount, see the table below.
Between 49 ft (15 m) and 66 ft (20 m), when using a connection pipe
other than that in the table, charge additional refrigerant with 0.2 oz/
ft (20g/1 m) as the criteria.

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 66 ft (20 m).
If the units are further apart than this, correct
operation can not be guaranteed.
