SELECTING THE MOUNTING
POSITION
INSTALLATION DIAGRAM OF
INDOOR AND OUTDOOR UNITS
Decide the mounting position with the customer as follows:
1. INDOOR UNIT
(1) Install the indoor unit level on a strong wall which is not subject
to vibration.
(2) The inlet and outlet ports should not be obstructed : the air should
be able to blow all over the room.
(3) Install the unit near an electric outlet or special branch circuit.
(4) Do not install the unit where it will be exposed to direct sunlight.
(5) Install the unit where connection to the outdoor unit is easy.
(6) Install the unit where the drain pipe can be easily installed.
(7) Take servicing, etc. into consideration and leave the spaces shown
in (Fig. 7). Also install the unit where the filter can be removed.
2. OUTDOOR UNIT
(1) If possible, do not install the unit where it will be exposed to di-
rect sunlight. (If necessary, install a blind that does not interfere
with the air flow.)
(2) Do not install the unit where a strong wind blows or where it is
very dusty.
(3) Do not install the unit where people pass.
(4) Take your neighbors into consideration so that they are not dis-
turbed by air blowing into their windows or by noise.
(5) Provide the space shown in Fig. 7 so that the air flow is not blocked.
Also for efficient operation, leave open three of the four direc-
tions front, rear, and both sides.
WARNING
Install at a place that can withstand the weight of the
indoor and outdoor units and install positively so that
the units will not topple or fall.
CAUTION
(1) Do not install where there is the danger of com-
bustible gas leakage.
(2) Do not install near heat sources.
(3) If children under 10 years old may approach the
unit, take preventive measures so that they can-
not reach the unit.

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 connectin the outdoor unit to the indoor
unit and insulation material is available for purchase locally.
When you purchase them, please specify the following.
A. Deoxidized annealed copper pipe for refrigerant piping as:

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.)

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.
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

NOTE:
In places where the outdoor temperature drops
to 32°F or lower, the drain water may freeze and
may stop up the drain or cause other outdoor
unit trouble. Therefore take measures so that
the drain water will not freeze and clog the
drain.

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.

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.
