(5) Refrigerant pipe connection
Pipe connection method:
• To ensure correct efciency, the pipe should be as short as possible.
• Coat refrigerant oil on the connector and the are nut.
• When bending the pipe, the bend diameter should be as large as
possible to prevent the pipe from breaking or kinking.
• When connecting the pipe, center it and thread the nut by hand.
• Then tighten it with the double spanners.
• Don't let any debris such as sand, water etc into the pipe.
Cautions in piping installation:
• When welding the connector use hard solder, charge nitrogen into the pipe to prevent oxidation. If not the oxygen lm in
the pipe will clog the capillary and the expansion valve. May even cause a deadly accident.
• The refrigerant pipe should be clean. If water or any other impurities enter the pipe, charge with nitrogen to clean the
pipe. The nitrogen should ow around the pressure of 72.5PSI(0.5Mpa). When charging the nitrogen, stop up the end of
the pipe by hand to enhance the pressure in the pipe, then move your hand to stop up the other end of the pipe.
• The piping installation should be done while the stop valves are closed.
• Before welding the valve and the pipes, use a wet cloth to cool down the valve and the pipes.
• When the connection pipe and branch pipe need to be shortened, please use special shears. Do not use a saw.
Pipe material and specs selection
1. Please select the refrigerant pipe of the below material.
Material: the phosphoric oxidize seamless copper pipe, model: C1220T1/2H (diameter is over 19.05); C1220T-0 (diameter is below 15.88).
2. Th i c k n e s s a n d s p e c s :
Conrm the pipe thickness and specs according to the pipe selection
method(the unit is with R410A, if the pipe over 19.05 is 0-type, the
pressure preservation will be bad, thus it must be 1/2H type and over
the min. thickness.
3. The branch pipe must be from Haier.
4. When installing the stop valve, refer to the relative operation instruction.
5. The pipe installation should be in the allowable range.
6. The installation of branch pipe and gather pipe should be performed
according to the relative manual.
When fastening and loosing the nut,
operate with double spanners, because
only one spanner cannot execute rmly.

Spanner
If threading the nut as not aiming at
the center, the screw thread will be
damaged, further it will cause leakage.
Drain pipe disposal
• Make sure the drain works properly.
• In regions where buildups of snow can
be expected, the accumulation and
freezing of snow in the space between
the heat exchanger and external plate
may lower operating efciency.
• After punching the knock-out hole, the
application of repair-type paint on the
surface around the edge sections is
recommended to prevent rust.
