Pipe Preparation
11.5.1 Pipe Preparation
1. Pipe & Electrical Wire Cutting
♦♦ Use cutting tools easily found in the market.
♦♦ Measure precisely both outer & inter pipes.
♦♦ The length of the pipe should be a little longer
♦♦ than the actual measured value.
♦♦ The wire should be 1.5m longer than the refrigerant
tube.
Fig.56
2. Reaming
♦♦ Clean the inside of the inner refrigerant tube.
♦♦ While reaming, the tube end must be on the top of the
reamer to prevent any dust going back into the tube.
Fig.57
3. Loosen two hanger bracket setting bolts (M8) on earth
side for less than 10mm. Remove two hanger bracket fixing
bolts (M6) on the rear side. Detach the hanger bracket by
pulling it backward (See Fig 14.5)
Fig.58
4. Wire Connecting and Taping
♦♦ (See the figure on right)

11.5.2 Refrigerant Piping work
The refrigerant is R410A£¬GWP=2020 ODP=0.
The standard pipe length is 5m. When the length (L) of the connecting pipe is less than or equals 7m, there
is no need to add refrigerant. If the connecting pipe is longer than 7m, it is required to add refrigerant. In the
below table, the amounts of refrigerant to be added for different models are listed for each additional meter of
pipe length.
Select copper pipes for gas and liquid as informed in specific table (see the pipe table below).For dust and
moisture protection, before assembly of the pipe and its insulation, both ends of the pipe must be covered.

Avoid pipe bending as much as possible, if it is necessary, the bending radius must be more than 3 or 4 cm.
Connection between an Indoor unit and an Outdoor Unit:
①Unscrew the flare nut for releasing pressure gas in the indoor unit. If there is no high pressure gas
blowing out, it is the signal of leakage for the indoor unit.
②Fit the flare nut to the liquid pipe. Flare the pipe’s end with flare tools.
③Tighten both flare nuts into gas pipe and liquid pipe at the indoor unit with two spanners.
11.5.3 Air Purging
The purpose of the air purging is to get rid of moisture and air in the system, otherwise moisture and air may
cause ineffectiveness of the compressor which directly affects the cooling capacity.
Purging by Using Vacuum
After tightening the flared nuts between the indoor and the outdoor unit
♦♦ Remove the blank cap of a three-way valve by using a torque wrench,
and then check if both high pressure and low pressure valves are in closed
condition or not.
♦♦ Remove the nut at the service port.
♦♦ Connect a gauge into the service port and a vacuum pump.
♦♦ Remove the gauge and tighten up the nut at the service port.
♦♦ Use a hexagonal wrench to open both high pressure and low pressure
valves to the end (counter clockwise).
♦♦ Tighten the blank cap of the three-way valve.
Fig.61
Gap Leakage Check
♦♦ Check if it leaks or not by applying soapsuds on every joint and then
inspect carefully. After the check, wipe them off completely.
♦♦ Cover the indoor unit joint with pipe insulation and four plastic bands
to prevent condensing at joints.

11.5.4 Liquid Pipe and Drain Pipe
If the outdoor unit is installed lower than the indoor unit (See Fig.63).
♦♦ A drain pipe should be above ground and the end of the pipe does not
dip into water. All pipes must be restrained to the wall by saddles.
♦♦ Taping pipes must be done from bottom to top.
♦♦ All pipes are bound together by tape and restrained to wall by saddles.
Fig.63
If the outdoor unit is installed higher than the indoor unit (See Fig.64).
♦♦ Taping should be done from lower to the upper part.
♦♦ All pipes are bound and taped together and also should be trapped to
prevent water from returning to the room (See Fig.64)
♦♦ Restraint all pipes to the wall with saddles.
Fig.64
CAUTION: make sure the drain flows out.
Drain pipe
●● The drain pipe outlet direction can be chosen from either the right rear or right.
●● The diameter of the drain pipe should be equal to or greater than the diameter of the connecting pipe.
(Vinyl tube: pipe size:20 mm, outer dimension: 26mm).
●● Keep the drain pipe as short as possible and incline downwards at a gradient of at least 1/100 to prevent
air pockets (See Fig.65)
●● Use the drain hose and clamp . Insert the drain hose completely into the drain socket, and tighten the
clamp within the range of the gray tape unit the screw head is less than 4mm above the hose (See Fig.66,67)
●● Insulate the clamp and drain hose by wrapping the sealing pad over them.
●● No folding of the drain hose is allowed in the indoor unit. (See Fig.68)
●● Confirm that smooth drainage is achieved after the pipe working.
●● Inject 600cc water into the drain pan from the air outlet to see if the drainage goes well or not. (See
Fig.69)
