It may decrease the system’s performance or cause compressor failure.
24/141
 Indoor unit - Refrigerant pipe connection
1. Purging the unit
- Indoor unit is supplied with a pre-charge of nitrogen gas. (insert gas)
- Purge the nitrogen gas before connect the refrigerant pipe
2. Connect the refrigerant pipe
- A smaller one for the liquid refrigerant
- A larger one for the gas refrigerant
- The inside of copper pipe must be clean & has no dust
25/141
 Outdoor unit - Branch Pipe Installation
Use the attached reducer properly according to the selected pipe size.
* Branch pipe for Gas pipe and Liquid pipe have different shape
<Liquid Pipe>
<high pressure gas Pipe>
<Gas Pipe>
< Reducer Mounting>
If the pipe is inserted deep into the reducer,
it can cause refrigerant noises
26/141
 Outdoor unit - Pipe connection
1. Remove the cover from unit.
2. Separate the knock-out hole to use.
If the hole is open, small animals such as squirrels and rats may get into the unit

Caution for connecting the pipe
 Use a flame proofing cloth to protect the unit from a welding fire or flame, otherwise the unit may get damaged by flame.
 Make sure not to damage the ambient temperature sensor located on the left side.
 Wrap the pipe before the service valve with a wet cloth and weld it as shown below.
To prevent the O-ring and Teflon packing inside service valve damaged by a welding fire.
 The connecting pipes of liquid side and gas side should not contact each other.
Vibration may cause a damage to the pipes
28/141
* Refrigerant pipes must be connected in parallel with the unit
29/141
For gas pipe only
30/141
 Brazing
- To prevent oxide while brazing, must carry out nitrogen replacement for oxygen free
* Oxide may form inside the pipe. It can cause the damage of the compressor, valves etc.
* Adjust the flow rate of the Nitrogen gas with a pressure regulator to maintain 0.05m 3/h or less.(0.02～0.05Mpa)
OK
Without Nitrogen blowing
Filter clinginess
Good Case
Bad Case
Nitrogen is not available to stay in the pipe
31/141
 Brazing
- Make sure that there is no moisture inside the pipe.
The stopper area of socket
should be spread with welding
material
- Make sure that there are no foreign materials and impurities in the pipe.
- Use Socket or Expending of pipe when brazing to connect pipes
- Direction of the pipe when brazing
: Performing the brazing of the pipe should be headed downward or horizontally
32/141
 Air Tight Test
- Perform the air Tight Test to check leakage with Nitrogen gas
* Pinching and Brazing end of each pipe → Connect Pressure Gage → Nitrogen gas pressurization → Check
◆ Test Pressure
- R-410A : 38kgf/cm2 = 4.12Mpa = 594.6psi
- R-22 : 28kgf/cm2 = 2.84Mpa
Nitrogen pressurization
1. Maintains 4.1MPa for 24 hours. If no leakage, then pressure down to 1MPa.
2. If there is pressure drop then find leak point and
3. Maintain 1MPa(145psi) until connecting the outdoor/indoor units to prevent corrosion in the copper pipes.
Maintain a pressure of 4.1MPa
Mark on the gage(wait for 24hours)
33/141
Maintain a pressure of 1.0MPa
 Insulation work for pipe
1) Insulate the refrigerant pipe pipe by referring to the thickness of insulator for each pipe size.
The standard condition is 30 °C & less than humidity 85%. (If the condition is in high humidity, use one grade thicker)

- All the refrigerant pipe & Drainpipe should be insulated to prevent dewing on the pipe.
Case 1
①EPDM length
should be longer
then pipe length.
Do not extend
EPDM by force
②Put the pipe in
EPDM insulation
carefully so that
the pipe will not
get damaged with
EPDM.
③Apply bond on
both side of cut
surface. Make
sure to use the
correct type of
bond for EPDM
④Dry it until it
becomes thick,
sticky and does
not get detached.
Case 2
Use the original uncut
insulation material.
Only in special case is the
vertical cutting of the
insulation allowed.
Apply bond both sides of
the surface of EPDM and
press them together for
long lasting bonding.
Dry it until it becomes thick
and sticky.
Case 3
Bring face to face the each
end of EPDM on fitting
connection part.
Make fitting cover to fit the
EPDM insulation. Fitting
cover should be overlapped
with insulation min
1inch(2.5m).
35/141
Bond the both cutting sides
of fitting cover.
- Refrigerant pipe before EEV kit and MCU or without EEV kit and MCU
You can contact the gas side and liquid side pipes but the pipes should not be pressed.
When contacting the gas side and gas side pipe, use 1 grade thicker insulator.
- Refrigerant pipe after EEV kit and MCU
After EEV kit or MC, expensed refrigerant for cooling or hot gas for heating will flow
through the refrigerant pipe. To prevent energy loss leave 10mm space between gas and
liquid pipe.
When contacting the gas side and liquid side pipe, use 1 grade thicker insulator.
36/141
 Insulation work for Branch pipe
1) Attach the insulation provided with a branch joint
2) Wrap the connected part with an insulation (purchased in the market) of a thickness of at least 10mm.
3) Use an insulation that should be able to handle the interior temperature over 120°C.
4) Wrap the branch joint with an insulation of a thickness of at least 10mm.
37/141
 Insulation for indoor units
1. Insulation
- Once you have checked that there are no leaks in the system, you can insulate the piping and hose.
- To avoid condensation problems, place T13.0 or thicker Acrylonitrile Butadiene Rubber separately to Gas & Liquid pipe.
- Wind insulating tape around the pipes and drain hose avoiding to compress the insulation too much.

- Correct : Use flaring tool or socket to connect each pipe
Butt brazing
Wrong size
42/141
 Bad case study
- Wrong : Use cooling water right after brazing to cool down the temperature quickly  It may cause crack or leakage
- Correct : Cool it down naturally or Wait for 3~5mins and then wipe the pipe on a wet tower to cool it down
Wait 3~5 mins before use wet towel
43/141
 Bad case study
- Wrong : Refrigerant Pipe is dented  pressure drop increase  bad refrigerant distribution
- Correct : Diameter of the pipe shouldn’t get any smaller or have any dents
44/141
 Bad case study
- Wrong : T shaped pipe used for liquid & Gas pipe  bad distribution of refrigerant & oil  compressor malfunction
- Correct : Use proper Y-joint
45/141
 Bad case study
- Wrong : Exposed insulator is decayed by sunlight  dewing on the surface
- Correct : Install cover on the refrigerant pipe
46/141
 Bad case study
- Wrong : No insulator on the flare  dewing  water drop
- Correct : Insulate all pipe.
47/141
 Bad case study
- Wrong : No additional insulator on the pipe  Pressred insulator  damaged & dewing on it
- Correct : Use additional insulator to secure certain thickness
48/141
 Bad case study
- Wrong : Vacuum pump
The oil in the vacuum pump flowed into the system
Use Vacuum pump solenoid adapter
by pressure difference while pump is stopped and
Or stop valve to avoid oil back flow
it can cause compressor damage
49/141
 Bad case study
- Wrong : Pressure gauge Mixed usage for R22 & R410A
- Correct : Use pressure gauge dedicated R410A
R410A
1. Pressure gauge can be burst because of high pressure.
2. Compressor failure
- If you use R22 gauge, remaining oil inside can generate wax type material
which definitely badly affect POE oil of R410A system, possibly clogging refrigerant passage or causing compressor failure
50/141
 Bad case study
- Wrong : Piping direction is wrong  bad distribution of refrigerant & oil  malfunction of the system
- Correct : Change the direction of piping
51/141
 Bad case study
- Wrong : Others
