Connection of Refrigerant Tubing

Connection the Unit with Flaring
Procedure

Flaring (If tubing is procured or cut
at the site).

1. Cut the copper tube to the
required length with a tube cutter.
It is recommended to cut approx.
30 cm-50 cm (12” to 20”) longer
than the tubing length you estimate.

2. Hold each tube downward when
cutting, remove burrs at the end of
the copper tube with a tube reamer
or file. This process is important
and should be done carefully to
make a good flare (Figure 2 and
Figure 3).

Copper tubing

Reamer

Figure 2

A good flare should have the
following characteristics:

-Inside surface is glossy and smooth.

- Edge is smooth.

-Tapered sides are of uniform length.

Cautions Before Connecting
Tubes Tightly

1. 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.

2. 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
(Figure 5).

Apply refrigerant lubricant here

4. Tighten the flare nut to the specified
tightening torque with torque
wrench and adjustable wrench
(Figure 7).

5. Repeat the process above for
the remaining line.

20-30 cm longer than the tube
length you estimate and put in the
straight line while cutting.

2. After cutting, remove burrs at the
end of copper tube with a tube
reamer. Hold the end downward
and be sure that no copper scraps
fall into the tube (Figure 2).

3. There are 2 methods to connect
copper tube

- Use tube connector between

4. Clean copper tube surfaces
both inside and outside before
connection, expansion, or brazing.

5. Insulate the entire gas line.

6. Do not allow uninsulated liquid line
to come in direct contact with bare
gas line.

7. Precautions should be taken to
avoid heat damage to the pressure
tap valve core during brazing. It is
recommended that a wet rag be
wrapped around the valve body.

8. It is recommended to use braze
shield, soak pad in water and place
over suction and liquid lines to
protect unit finish.

9. To braze the copper tube, before
brazing a copper tube to a solder
coupling or a copper tube to an
expanded tube, do not forget to
keep them tight as shown in
figure 10.

Gas Leakage Inspection

Gas Leakage Inspection

After charging with refrigerant,
it is necessary to check gas leakage.
Inspecting gas leakage should be
done with special precaution. If there
is any leakage that we are unable to
find, afterwards the system would be
damage. For example, if R22
refrigerant loses, cooling coil will be
frozen. There are so many methods to
inspect leakage, but the easiest and
the most economical way is to use
nitrogen gas detector and bubble of
powder detergent per the following
steps:-

•Prepare nitrogen tube with pressure
regulator and pressure gauge or
manifold gauge.

• Open service valve cover (at the
suction side).

• Connect gauge line to the nitrogen
tank, but do not open nitrogen
valve at the nitrogen tank.

• Check out brazing track and all
valves such as flare union.

• Connect the other tails of gauge
line to the service valve (at the
suction side).

•Slowly open nitrogen valve,
let pressure gradually increase until
250 pound/square inches, then put
bubble of powder detergent around
all connected joints, notice any
leakage. Fix the leakage, if any.
If there is no leakage, leave 1-2 hours
to check whether the pressure stays
the same. If the pressure is still
reducing, we need to check leakage
again. Finally, release nitrogen gas
in order to make refrigerant system
to be under vacuum.

Caution

• Do not fully open nitrogen valve to
250 psig because valve may be
damage.

• Do not forget to check the leakage
at the access valve both at the
liquid line and at the suction line.

WTK-SVN001-EN

Air Evacuation
and Refrigerant Charge

Evacuation

Air and humidity are the enemy of
the air-conditioning system because
humidity will react with R22 refrigerant
and turns into acid, which will corrode
the wire coil and reduce the
compressor oil’s efficiency. Evacuation
is a must to prevent refrigerant system
from air and humidity.

Evacuation Procedure

Connect the middle hose of service
gauge to the vacuum pump, then
connect the hose at the low side to
“service valve” of air-conditioning
at suction line. Connect the hose at
the high side to “service valve” at
liquid line (figure 13).

Fill up R22 refrigerant into the
system

To fill up R22 refrigerant is the final
step of installation. After leakage
check and power wiring, fill up R22
refrigerant to the system.

How to fill up R22 refrigerant

Normally, this needs to be done
immediately after air evacuation per
the following steps (figure 13)

•Fill up the refrigerant via valve at
liquid line until pressure of the
liquid line is around 120-150 psig
(Don’t forget to evacuate air from
liquid line before)

•Turn on evaporator and condensing
unit.

•Fill up the refrigerant into suction
line at the proper quantity while the
unit is working.

• Let machine run for at least 20
minutes. Read pressure from
pressure gauge “at both high and
low side”, and read current
from amp-meter. Usually, suction
line pressure should be around
65-70 psig , and liquid line pressure
should be around 250-275 psig.

If the pressure readings of both liquid
line and suction line are in the range
stated above and electric current
reading is at full load ampere of
condensing unit, it indicates that
refrigerant’s volume is sufficient.

• But if suction pressure is lower than
normal and electric current is far
below full load ampere, it indicates
that refrigerant is inadequate.
You need to add more refrigerant.

• If suction pressure is higher than
normal and electric current is over
the full load ampere, and you notice
some water spray holds on the
compressor, it indicates over cooling
system. You need to release some
refrigerant.

Remark: When the interconnecting
line is longer than 7.5 m, additional
charging is necessary. For the additional
amount, follow the table belows.

Wiring and System Inspection before
Test Run and Condenser Cleaning

Electric wire and ground wire must
comply with each country’s or regional’s
regulation.

1. Wiring

Importance

- Check the unit nameplate for
electrical rating. Make sure that
the wiring is according to local
codes and wiring system diagram.

-A separate power supply
disconnect and a circuit breaker
for overcurrent protection should
be provided in the external power
supply line.

-Always connect ground wire to
condensing unit every time to
prevent an electric shock in case
of an electric leakage.

-Electric wires shall not contact
to refrigerant pipes, compressor,
motor and the other moving parts.

- Manufacturer assumes no liability
for the problems caused by
unauthorized change in the
internal wiring.

- Should tighten up wire connection.

-Electric conductor parts must be
copper only.

To inspect system before test run.

After finished installing
air-conditioning, all system shall be
inspected before starting.

• Check that all brazings are correctly
made.

• Check that units are correctly
installed and there are no other
tools near or on top of the unit.

• Check the tubing and connections
for leak.

• Check that unit has a proper
ground wiring.

• Check for proper voltage and fuse
size.

• Check electrical wire size used is
as specified.

• Check all field wiring for tight
connection.

• Make sure that electrical wires
inside the unit do not contact to
refrigerant pipes.

•Turn on the unit, check the system
carefully.

Condenser Cleaning

After air-conditioning works for
a while, it may cause scales at the
surface of pipe in the condensing unit,
which may cause by cooling water
or rust inside cooling tower. Installer
can notice from the reduction of water
velocity, or the reduction of difference
of water temperature in and out,
or condensing temperature is higher
than normal.

Therefore, to maintain efficiency of
condenser, installer must clean up the
pipe’s inside surface of condenser to
prevent scales.

To clean up condenser with chemical

To clean up condenser with chemical
is one of the methods to wipe out
scales. To select proper chemical,
installer need to consult the water
treatment expert.

2. Electric Wire Connection

- See wiring diagram on page 12

-Slipover electric wire at the end

-After connect electric wire,
check whether all screws are
firmly tightened

The electric wire connection between
outdoor and indoor unit should be
according to the wiring diagram.
