12.5 Connecting Pipe Preparation
12.51 Pipe Preparation
Pipe & Electrical Wire Cutting
1. Use cutting tools easily found in the market.
2. Measure precisely both outer & inter pipes.
3. The length of the pipe should be a little longer
than the actual measured value.
4. The wire should be 1.5m longer than the
refrigerant tube
Reaming
1. Clean the inside of the inner refrigerant tube.
2. While reaming, the tube end must be on the top of
the reamer to prevent any dust going back into the
tube.
Flaring the Pipe End
Flare both ends of the pipe with flaring kits by
fitting the flare nut on the pipe before flaring. Set the die
on the pipe in the way that the pipe end is 0.5mm above
the top of the die. Then, check if the pipe end is even and
perfectly round or not.

12.5.2 Refrigerant Piping work
The refrigerant is R410A for" " series outdoor units,
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 5m, 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.

12.5.3 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
units
1. 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.
2. Remove the nut at the service port.
3. Connect a gauge into the service port and a vacuum pump.
Remove the gauge and tighten up the nut at the service port.
4. Use a hexagonal wrench to open both high pressure and low pressure valves to the end (counter
clockwise).
5. Tighten the blank cap of the three-way valve.
Gap Leakage Check
1. Check if it leaks or not by applying soapsuds on every
joint and then inspect carefully. After the check, wipe
them off completely.
2. Cover the indoor unit joint with pipe insulation and
four plastic bands to prevent condensing at joints.
