there will be frost formed on the heat exchanger, when
indoor heat exchanger temperature decreased below 0 C,
the indoor unit micro-computer will stop compressor running
and protect the unit.

Principle:

1. Air conditioner absorbs heat from the outdoor and transmit
to indoor and evaporated, so that indoor temperature
increased. Its heating capacity will decrease by the
decrease of outdoor ambient temperature.

2. If outdoor temperature got lower, please operate with

other heating ventilating equipments.

o

EG

Defrosting:

1. When outdoor temperature is low but high humidity, after a

long while running, frost will form on outdoor unit, that will
effect the heating effect. At this time, the auto defrosting
function will act, and the heat running will stop for 8-10
minutes.

2. During the auto defrosting function, both the fan motors of
indoor unit and outdoor unit will stop operate.

3. During the defrosting function, the indoor indicator flashes
and the outdoor unit may emit vapor. This is due to the
defrosting, it is not malfunction.

4. After defrosting finished, the heating will recover

automatically.

Cold Draft Prevention:

In "HEAT" mode, the indoor blower will no act at the
following 3 status, while the heat exchanger haven't achieve
the certain temperature. This is to prevent cool air blowing.
(Within 2 minutes).

10.2 Refrigerant Tubing

10.2.1 Use of The Flaring Method

Many of the conventional split system air
conditioners employ the flaring method to
connect refrigerant tubes which run between
indoor and outdoor units. In this method, the
copper tubes are flared at each end and
connected with flares nuts.

10.2.2 Flaring Procedure With A Flare
Tool

•

Cut the copper tube to the required length
with a tube cutter. It is recommended to
cut approx. 30 - 50 cm longer than the
tubing length you estimate.

•

Remove burrs at the end of the copper
tube with a reamer or file. This procedure
is important and should be done carefully
to make a good flare. (Fig.25)

NOTE

When reaming, hold the tube end
downward and be sure that no
copper scraps fall into the tube.
(Fig.26)

•

Remove the flare nut from the unit and be
sure to mount it on the copper tube.

•

Make a flare at the end of copper tube with
a flare tool.* (Fig.27)
(*Use "GRID" or equivalent.)

NOTE

10.2.3 Caution Before Connecting Tubes
Tightly

•

Be sure to apply a sealing cap or water­ proof tape to prevent dust or water from
getting into the tubes before they are used.

•

Be sure to apply refrigerant lubricant to the
matching surfaces of the flare and union
before connecting them together. This is
effective for reducing gas leaks. (Fig.28)

•

For proper connection, align the union tube
and flare tube straight with each other, then
screw in the flare nut lightly at first to obtain
a smooth match. (Fig.29)

A good flare should have the
following charactcteristics:

- inside surface is glossy and
smooth.

- edge is smooth.

- tapered sides are of uniform
length.

IMPORTANT

To prevent heat loss and wet floors due to dripping
of condensation, both tubes must be well
insulated with a proper insulation material. The
thickness of the insulation should be a min. 8 mm.
(Fig. 31, 32)

CAUTION

After a tube has been insulated, never try to bend
it into a narrow curve, as this may cause to break
or crack.

10.2.6 Taping the Tubes

•

At this time, the 2 refrigerant tubes (and
electrical wire if codes permit) should be taped
together with armoring tape. The drain hose
may also be taped together as 1 bundle with
the tubing.

•

Wrap the armoring tape from the bottom of the
outdoor to the top of tubing where it enters the
wall. As you wrap the tubing, overlap half of
each previous tape turn. (Fig. 33)

Clamp tubing bundle to wall, using 1 clamp

clear of the unit and the tubing.

10.2.7 Finish the Installation

After finishing insulating and taping over the
tubing, use sealing putty to seal off the hole in
the wall to prevent rain and draft from entering.

10.3 Air Purging

Air and moisture remaining in the refrigerant
system have undersirable effects as indicated
below. Therefore, they must be purged
completely.

• Pressure in the system rises

• Operating current rises

• Cooling (or heating) efficiency drops

• Moisture in the air may freeze and block
capillary tubing.

• Water may lead to corrosion of parts in the
refrigerant system.

AIR PURGING WITH A VACUUM PUMP
(FOR TEST RUN)

1. Check that each tube (both narrow and wide
tubes) between the indoor and outdoor units
have been properly connected and all wiring
for the test run has been completed. Noted
that both narrow and wide tube service valves
on the outdoor unit are kept closed at this
stage.

Outdoor unit

Manifold valve

2. Using a adjustable wrench or box wrench,
remove the valve caps from the service on
both narrow and wide tubes.

3. Connect a vacuum pump and a manifold
valve (with pressure gauges) to the service
port on the wide tube service valve. (Fig.35)

CAUTION

Be sure to use a manifold valve for air
purging. If it is not available, use a stop valve
for this pupose. The "Hi" knob of the
manifold valve must always be kept closed.

4. With the "Lo" knob of the manifold valve open,
run the vacuum pump. The operation time for
the vacuum pump varies with tubing length
and the capacity of the pump. The following

5. With the vacuum pump still running, close
the "Low" knob of the manifold valve. Then
stop the vacuum pump.

6. With the accessory hex wrench, turn the
valve stem on the narrow tube service valve
counter-clockwise by 90 degrees (1/4 turn)
for 10 seconds, and then turn the stem
clockwise to close it again. (Fig.36)

CAUTION

Be sure completely insert the hex
wrench before attempting to turn
the valve.

7. Leak test all joints at tubing (both indoor and
outdoor) with liquid soap. Bubbles indicate a
leak. Be sure to wipe off the soap with a
clean cloth.

8. WIth the hex wrench, turn the wide tube
service valve stem counter-clockwise to fully
open the valve.

10. Loosen the vacuum hose connected to the
wide tube service port slightly to release the
pressure. Then, remove the hose.

CAUTION

This may cause the refrigerant gas
to leak. In order to avoid this, take
off the hose quickly.

11. Fasten the valve cap on the wide tube
service port securely with an adjustable
wrench or box wrench. Next, mount the
valve cap on the service valve and
tightened it to 200 kg-cm with a torque
wrench. This process is very important to
prevent gas leaking from the system.

12. Test run the air conditioner. (See page 34)

15. Wipe off the soap on the tubing.

13. While the air conditioner is running, apply
liquid soap to check for any gas leaks
around the service valves or caps.

14. If there is no leakage, stop the air
conditioner.

This completes air purging with a
vacuum pump and the air conditioner is
ready for actual operation.

11. PUMP DOWN

11.1 What is Pump Down?

Pump down means collecting all refrigerant gas
in system back into the outdoor unit without
losing any of gas. Pump down is used when the
unit is to be moved or before serving the
refrigerant circuit.

11.2 Pump Down Procedure

Indoor unit

NOTE

1. Connect the Lo side charging hose of the
manifold valve to the service port on the wide
tube service valve. (Fig 39)

2. Using a hex wrench, turn the narrow tube
service valve clockwise all the way to close
the service valve (Fig 40). (Be sure to confirm
that the wide tube service valve is fully open.)

3. Press the ON / OFF button and start cooling
operation.

4. When the low pressure gauge reading falls
from 1 to 0.5 kg/cm
