Refrigerant amount
Before shipment, this air conditioner is filled
with the rated amount of refrigerant including
additional amount required for air-purging,
subject to 7.5m piping length. (The rated amount
of refrigerant is indicated on the name plate.)
But when the piping length exceeds 7.5 meters,
additional charge is required according to the
following table.
Example:
In case of 10m long pipe(one-way), the amount
of refrigerant to be replenished is:
(10 - 7.5) x 70 = 175g

Installation of Unit
Preparation of Piping
Main cause of gas leakage is defect in flaring
work. Carry out correct flaring work in the
following procedure.
1. Cut the pipes and the cable.
• Use the accessory piping kit or the pipes
purchased locally.
• Measure the distance between the indoor
and the outdoor unit.
• Cut the pipes a little longer than measured
distance.
•
Cut the cable 1.5m longer than the pipe
length.
2. Burrs removal
• Completely remove all burrs from the cut
cross section of pipe/tube.
•
Put the end of the copper tube/pipe to
downward direction as you remove burrs in
ord
er to avoid to let burrs drop in the tubing.
3. Putting nut on
• Remove flare nuts attached to indoor and
outdoor units, than put them on pipe/tube
having completed burr removal.
(Not possible to put them on after flaring work)
4. Flaring work
•
Carry out flaring work using dedicated
flaring tool for R-22 as shown below.
Firmly hold copper tube in a bar(or die) as
indicated dimension in the table above.
5. Check
• Compare the flared work with figure below.
• If flare is noted to be defective, cut off the
flared section and do flaring work again.

Connection of piping
• Align the center of the pipings and suffciently
tighten the flare nut with fingers.
• Finally, tighten the flare nut with troque
wrench until the wrench clicks.
When tightening the flare nut with troque
wrench, ensure the direction for tightening
follows the arrow on the wrench.
1.
If it is necessary to bend or stretch the
tubing, use the spring which is attached to
the tubing in stead of pipe bender.
• Please make a careful notice to make a
smooth line.
• Hold the tubing with your two hands closely
and then bend or stretch it slowly not to
make any crack.
• Remember that the radius (R) should not
exceed 70mm (Refer to Fig. 1)
2. Do not repeat the bending process to prevent
the tubing from cracking or crushing.
3. Keep in mind that the bending part should
not be cracked and make the radius (R) as
long as possible (Refer to Fig. 2)

Power Supply and Wiring
The unit is completely wired internally at the
factory according to general rule of electrical
technology, but local rules, if they are required,
should be complied with.
1. Power supply
Power source must fulfill the following
conditions:
• The working voltage should be higher than
90% and lower than 110% of the rated
voltage marked on the name plate.
• The starting voltage should be higher than
85% of the rated voltage marked on the
name plate.

• Provide a recognized circuit breaker as
below between power source and unit.
A disconnection device to adequately
disconnect all supply lines must be fitted.
(for service operations)
• The screws which fasten the wiring in the
casing of electrical fittings are liable to
come loose from vibrations to which the
unit is subjected during the course of
transportation. Check them and make sure
that they are all tightly fastened.
(If they are loose, it could give rise to burn-
out of the wires.)
• See to it that the starting voltage is
maintained at more than 90 percent of the
rated voltage marked on the name plate.
• The following troubles would be caused by
voltage drop-down.
Vibration of a magnetic switch, damage on
the contact point there of, fuse breaking,
disturbance to the normal function of a
overload protection device.
2. Wiring

Vacuum Drying of the Connecting Pipes and the Indoor Unit
The air which contains moisture remaining in the refrigeration cycle may cause a malfunction on the
compressor.
1. Confirm that both the liquid side valve and the gas side valve are set to the closed position.
2. After connecting the piping, check the joints for gas leakage with gas leak detector.
3. Remove the service port nut, and connect the gauge manifold and the vacuum pump to the service
port by the charge hose.
4. Vacuum the indoor unit and the connecting pipes until the pressure in them lowers to below -
76cmHg.
5. Remove the valve stem nuts, and fully open the stems of the 2-way and 3-way valves with a hexagon
wrench.
6. Tighten the valve stem nuts of the 2-way valve and 3-way valve.
7. Disconnect the charge hose and fit the nut to the service port.

Form the Piping
1. Wrap the connecting portion of indoor unit
with the insulation material and secure it with
two Plastic Bands. (for the right piping)
• If you connect an additional drain hose,
the end of the drain-outlet should be kept
distance from the ground. (Do not dip it
into water, and fix it on the wall to avoid
swinging in the wind.)
2. Tape the Piping, and Connecting Cable from
down to up.
3. Form the piping gathered by taping along the
exterior wall and fix it onto the wall by saddle
or equivalent.
1. Tape the piping and connecting cable from
down to up.
2. In order to prevent water from entering the
room, form a trap and tape the piping.
3. Fix the piping onto the wall with saddle or
bracket.

Final Check and Test Run
Installation Manual 19
After installing the unit, perform the final check
and running test as follows:
Final check points
Is the unit securely mounted?
Is the installation location adequate?
Is the water piping work adequately and
without leakage?
Are trapped drain lines installed at
condensate drain connections?
Has the refrigeration cooling cycle been
kept sealed?
Is the electrical wiring adequate and are
the screws tightened on terminals?
After the above final checkings, prepare the
running test as follows:
Connect compound gauges to the check
joints at discharge and suction sides of
the compressor.
Turn all switches "OFF".
Turn the main switch "ON".
Running test should be accomplished as follows:
Set operation switch at "FAN" and the fan
will start. Check to ensure that the fan
sounds normal.
Next, set it at "COOL" and the
compressor will start. Check to ensure
that the compressor sounds normal.
Check discharge and suction pressure on
the compound gauges.
Check working voltage, phase balance
and running current.
Check to ensure that the thermistor
functions properly.
Check to ensure that the high pressure
control switch functions correctly.
