(4)
(5)
Before starting work, check that power is not being
supplied to the outdoor unit.
Match the terminal board numbers and connection
cord colors with those of the outdoor unit.
Erroneous wiring may cause burning of the electric
parts.
Connect the connection cord firmly to the terminal
board. Imperfect installation may cause a fire.
Always fasten the outside covering of the connec-
tion cord with the cord clamp. (If the insulator is
chafed, electric leakage may occur.)
Always connect the ground wire.
CAUTION
When the voltage is low and the air conditioner is diffi-
cult to start, contact the power company the voltage
raised.
CAUTION
(1)
(2)
Check that the indoor unit correctly receives the signal
from the remote control unit, then install the remote
control unit holder.
Select the remote control unit holder selection site by
paying careful attention to the following:
Avoid places in direct sunlight.
Select a place that will not be affected by the heat
from a stove, etc.

The rated voltage of this product is 220-240V AC
50Hz.
Before turning on verify that the voltage is within the
198V to 264V range.
Always use a special branch circuit and install a special
receptacle to supply power to the air conditioner.
Use a special branch circuit breaker and receptacle
matched to the capacity of the air conditioner.
(Fuse/Breaker capacity : 30 A)
The special branch circuit breaker is installed in the per-
manent wiring. Always use a circuit that can trip all the
poles of the wiring and has an isolation distance of at
least 3mm between the contacts of each pole.
Perform wiring work in accordance with standards so
that the air conditioner can be operated safely and
positively.
Install a leakage special branch circuit breaker in
accordance with the related laws and regulations
and electric company standards.

GAS LEAKAGE INSPECTION
INSTALLING THE COUPLER HEAT
INSULATION
After checking for gas leaks, insulate by wrapping insulation around the
two parts (large and small) of the indoor unit coupling, using the coupler
heat insulation.
After installing the coupler heat insulation, wrap both ends with vinyl
tape so that there is no gap.
Secure both ends of the heat insulation material using nylon fasteners.
Fig. 29
When using an auxiliary pipe, make sure that the fastener
used is insulated in the same way.
DRAIN PIPING
Install the drain pipe with downward gradient (1/50 to 1/100) and so
there are no rises or traps in the pipe.
Use general hard polyvinyl chloride pipe (VP25) [outside diameter 38
mm].
During installation of the drain pipe, be careful to avoid applying
pressure to the drain port of the indoor unit.
When the pipe is long, install supporters (Fig. 30).
Do not perform air bleeding.
Always heat insulate (8mm or over thick) the indoor side of the drain
pipe.
Fig. 30
Install insulation for the drain pipe. (See Figs. 31 and 32.)
Cut the included insulation material to an appropriate size and
adhere it to the pipe.

HOW TO CONNECT WIRING TO THE TERMINALS
A. For solid core wiring (or F-cable)
Cut the wire and with a wire cutter or wire-cutting pliers,
then strip the insulation to about 15/16” (25 mm) of
expose the solid wire.
Using a screwdriver, remove the terminal screw(s) on
the terminal board.
Using pliers, bend the solid wire to form a loop suitable
for the terminal screw.
Shape the loop wire properly, place it on the terminal
board and tighten securely with the terminal screw
using a screwdriver.
B. For strand wiring
Cut the wire and with a wire cutter or wire-cutting
pliers, then strip the insulation to about 3/8” (10 mm) of
expose the strand wiring.
Using a screwdriver, remove the terminal screw(s) on
the terminal board.
Using a round terminal fastener or pliers, securely
clamp a round terminal to each stripped wire end.
Position the round terminal wire, and replace and
tighten the terminal screw using a screwdriver.

Install the filter guide.
Install the intake grills.
Install side covers A and B (if the unit is installed in a half-
concealed orientation, only install side cover A).
Install the air filters.

When moving and installing the air conditioner, do not
mix gas other than the specified refrigerant (R22)
inside the refrigerant cycle.
When adding refrigerant, add the refrigerant from the
charging valve at the completion of work.
If the units are further apart than the maximum pipe
length, correct operation can not be guaranteed.

CAUTION
AIR PURGE
1. AIR PURGE
Remove the cap, and connect the gauge manifold and the vacuum
pump to the charging valve by the service hoses.
Vacuum the indoor unit and the connecting pipes until the pres-
sure in them lowers to below 1.5 mmHg.
Disconnect the service hoses and fit the cap to the charging valve
(Tightening torque : 70 to 90 kgf • cm).
Remove the blank caps, and fully open the spindles of the 2-way
and 3-way valves with a hexagon wrench (Torque : 2-way valve:
70 to 90 kgf • cm, 3-way valve: 100 to 120 kgf • cm).
Tighten the blank caps of the 2-way valve and 3-way valve to the
specified torque (200 to 250 kgf • cm).

2. ADDITIONAL CHARGE
Refrigerant suitable for a piping length of 5 m is charged in the outdoor
unit at the factory.
When the piping is longer than 5 m, additional charging is necessary.
For the additional amount, see the table below.
Between 5 m and 30 m, when using a connection pipe other than that in
the table, charge additional refrigerant with 1.8 oz (40 g) / 3.3 ft (1 m) (Re-
verse cycle model), 0.6 oz (17 g) / 3.3 ft (1 m) (Cooling model) as the cri-
teria.
