(1) The function of main control

1. Time delay Safety Control

• 3min.; The compressor operation is delayed for 3 minutes to balance the pressure of cycle.
(Protection of compressor)

• 5sec.;

The indoor fan is delayed for 5 seconds, when operating initially, to prevent noises occurred by the vertical
louver and wind.

• 2min.; The reversing valve is delayed for 2 minutes to prevent the refrigerant-gas for abnormal noise when the
heating operation is OFF or switched to the other operation mode while compressor is off.
While compressor is running, it takes 3~5 seconds to switch.

2. Chaos Swing Mode

• By the Chaos Swing key input, the upper/lower vane automatically operates with the Chaos Swing or they are

fixed to the desired direction.

• While in Chaos Swing mode, the angles of cooling and heating cycle operations are different.

3) How to fix installation plate

The wall you select should be strong and solid enough to
prevent vibration

1. Mount the installation plate on the wall with four
type A screws. If mounting the unit on a concrete
wall, use anchor bolts.

■ Mount the installation plate horizontally by aligning the
centerline using a level.

2. Measure the wall and mark the centerline. It is also
important to use caution concerning the location of
the installation plate-routing of the wiring to power
outlets is through the walls typically. Drilling the
hole through the wall for piping connections must
be done safely.

■ For right rear piping and left rear piping, draw a line in the
direction of the arrow marked "A". The meeting point of the
two lines is the center of the hole.

• The position of the center of the hole.

4) Drill a hole in the wall

(3) Flaring work and connection

of piping

1) Flaring work

Main cause for gas leakage is due to defect in flaring
work. Carry out correct flaring work in the following pro­cedure.

1. Cut the pipes and the cable.

■ Use the piping kit accessory 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(4.9ft) 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 in a downward
direction as you remove burrs in order to avoid dropping
burrs into the tubing.

3. Putting nut on

■ Remove flare nuts attached to indoor and outdoor unit,
then 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 flaring tool as shown below.

Firmly hold copper pipe in a die in the dimension shown 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.

(5) Checking the Drainage and

forming the pipings

1) Checking the drainage

1. To remove the front panel from the indoor unit,
remove the front panel from the indoor unit cabinet.

■ Set the air direction louvers up-and-down to the posi­tion(horizontally) by hand.

■

Remove the securing screws that retain the front panel.
Pull the lower left and right sides of the grille toward you
and lift it off. (9K Btu models: 2EA,12K Btu models: 3EA)

2. To check the drainage.

■ Pour a glass of water on the evaporator.

■ Ensure the water flows through the drain hose of the

indoor unit without any leakage and goes out the drain
exit.

3. Drain piping

■ The drain hose should point downward for easy drain
flow.

■ Do not make drain piping.

2) Form the piping

1. Form the piping by wrapping the connecting por­tion of the indoor unit with insulation material and
secure it with two kinds of vinyl tapes.

■ If you want to connect an additional drain hose, the end
of the drain outlet should be routed above the ground.
Secure the drain hose appropriately.

2. In cases where the outdoor unit is installed below
the indoor unit perform the following.

■ Tape the piping, drain hose and connecting cable from
down to up.

■ Secure the tapped piping along the exterior wall using
saddle or equivalent

3. In cases where the Outdoor unit is installed above
the Indoor unit perform the following.

■ Tape the piping and connecting cable from down to up.

■ Secure the taped piping along the exterior wall. Form a

trap to prevent water entering the room.

■ Fix the piping onto the wall by saddle or equivalent.

(6) Air Purging

Air and moisture remaining in the refrigerant system have
undesirable effects as indicated below.

• Pressure in the system rises.

• Operating current rises.

• Cooling(or heating) efficiency drops.

• Moisture in the refrigerant circuit may freeze and block

capillary tubing.

• Water may lead to corrossion of parts in the refrigeration
system.

Therefore, the indoor unit and tubing between the indoor and
outdoor unit must be leak tested and evacuated to remove
any noncondensables and moisture from the system.

Air Purging with a Vacuum Pump

■ Preparation

Check that each tube(both liquid and gas side tubes)
between the indoor and outdoor units has been properly
connected and all wiring for the test run has been com­pleted. Remove the valve caps from both the gas and the
liquid side service valves on the outdoor unit. Note that
both liquid and gas side service valves on the outdoor unit
are kept closed at this stage.

■ Leak test

1. Connect the manifold valve(with pressure gauges)
and dry nitrogen gas cylinder to this service port
with charge hoses.

CAUTION: Be sure to use a manifold valve for air purg-

ing. If it is not available, use a stop valve for
this purpose. The "Hi" knob of the manifold
valve must always be kept close.

2. Pressurize the system to no more than 150 P.S.I.G
with dry nitrogen gas and close the cylinder valve
when the gauge reading reached 150 P.S.I.G. Next,
test for leaks with liquid soap.

CAUTION: To avoid nitrogen entering the refrigerant sys-

tem in a liquid state, the top of the cylinder
must be higher than its bottom when you pres­surize the system. Usually, the cylinder is
used in a vertial standing position.

3. Do a leak test of all joints of the tubing(both indoor
and outdoor) and both gas and liquid side service
valves. Bubbles indicate a leak. Be sure to wipe off
the soap with a clean cloth.

4. After the system is found to be free of leaks, relieve
the nitrogen pressure by loosening the charge
hose connnector at the nitrogen cylinder. When the
system pressure is reduced to normal, disconnect
the hose from the cylinder.

■ Evacuation

1. Connect the charge hose end described in the pre­ceding steps to the vacuum pump to evacuate the
tubing and indoor unit.
Confirm the "Lo" knob of the manifold valve is
open. Then, run the vacuum pump.
The operation time for evacuation varied with the
tubing length and capacity of the pump. The follow­ing table shows the amount of time for evacuation.
Allow the pump to operate until the system has
been evacuated down to 300 microns. Allow the
pump to continue running for an additional 15 min­utes. Turn off the pump and leave the connections
secured to the two service valves. After 5 minutes,
if the system fails to hold 500 microns or less,
check all connections for tight fit and repeat the
evacuation procedure.

2. When the desired vacuum is reached, close the
"Lo" knob of the manifold valve and stop the vacu­um pump.

■ Finishing the job

1. With a service valve wrench, turn the valve stem of
liquid side valve counter-clockwise to fully open
the valve.

2. Turn the valve stem of gas side valve counter­clockwise to fully open the valve.

3. Loosen the charge hose connected to the gas side
service port slightly to release the pressure, then
remove the hose.

4. Replace the flare nut and its bonnet on the gas side
service port and fasten the flare nut securely with
an adjustable wrench. This process is very impor­tant to prevent gas leakage from the system.

5. Replace the vlave caps at both gas and liquid side
service valves and fasten them securely tight.

This complete air purging with a vacuum pump. The air
conditoner is now ready to test run.

(7) Test running

1. Check that all tubing and wiring have been properly
connected.

2. Check that the gas and liquid side service valves are
fully open.

1. Prepare remote control

Remove the battery cover by pulling it according to the
arrow direction.

Insert new batteries making sure that the (+) and (–) of
battery are installed correctly.

Reattach the cover by pushing it back into position.

NOTE:

• Use 2 AAA(1.5volt) batteries. Do not use rechargeable

batteries.

• Remove the batteries from the remote control if the sys-

tem is not going to be used for a long time.

2. Settlement of outdoor unit

■ Anchor the outdoor unit with a bolt and
nut(ø10mm:0.39") tightly and horizontally on a concrete
or rigid mount.

■ When installing on the wall, roof or rooftop, anchor the
mounting base securely with a nail or wire assuming the
influence of wind and earthquake.

■ In the case when the vibration of the unit is conveyed to
the hose, secure the unit with an anti-vibration rubber.

3. Evaluation of the performance

Operate unit for 15~20 minutes, then check the system
refrigerant charge:

1. Measure the pressure of the gas side service valve.

2.

Measure the temperature of the intake and discharge of air.

3. Ensure the difference between the intake temperature
and the discharge is more than 8°C(46˚F) (Cooling) or
reversely (Heating).

4. For reference; the gas side pressure of optimum condi­tion is as below. (Cooling)

NOTE:

• If the actual pressure are higher than shown, the system

is most likely over-charged, and charge should be
removed. If the actual pressure are lower than shown,
the system is most likely undercharged, and charge
should be added.

• The air conditioner is now ready for use.

- 37 -

This is performed when the unit is to be relocated or the
refrigerant circuit is serviced.

Pump Down means collecting all refrigerant in the outdoor unit
without loss in refrigerant gas.

CAUTION:

Be sure to perform Pump Down procedure with the unit cooling
mode.

Pump Down Procedure

1. Connect a low-pressure gauge manifold hose to the charge port
on the gas side service valve.

2. Open the gas side service valve halfway and purge the air from
the manifold hose using the refrigerant gas.

3. Close the liquid side service valve(all the way in).

4. Turn on the unit's operating switch and start the cooling operation.

5. When the low-pressure gauge reading becomes 1 to 0.5kg/cm

2

G(14.2 to 7.1 P.S.I.G.), fully close the gas side valve stem and
then quickly turn off the unit. At that time, Pump Down has been
completed and all refrigerant gas will have been collected in the
outdoor unit.
