5.3.2 Piping connection
5.3.2.1 Connecting Of Refrigerant Pipe
a) Only the correctly installing of indoor and outdoor unit done, can the refrigerant
pipe be connected.
b) The cut-off valves are completely close before ex-work. Before connecting the
refrigerant pipe, be careful to check whether the valves are completely close.
c) The connecting procedure of refrigerant pipe: first, unscrew the two valves on the
outdoor unit and the pipe-jointing nut on the indoor unit(please keep them
carefully). Please connect the refrigerant pipe according to the manual, the
pipe-jointing nut should be screw tightly and no leakage. Note: you need two
wrenches to make balance.
d) When the connecting of refrigerant pipe is finished, before power on the system,
you should vacuum the indoor unit through the maintenance port on the cut-off
valves, or open the high-pressure valve, and exhaust the air through the
maintenance port on the low-pressure valve(closed). It will take about ten
seconds. Then screw tightly the maintenance port. (When supplement the
refrigerant, fill through the maintenance port of the low-pressure valves on the
outdoor unit).
e) Open all the valves completely before power on the system, or it will be sick for
low efficiency.
f) Gas leak check. Make sure no gas from connections with leak detector or soap
water.
5.3.2.2 Pipe Connecting Procedures
Completely shut the cut-off valves of the outdoor unit (as ex-work status). Unscrew the
nuts on the cut-off valves and immediately connect the reamer joint (in 5 minutes). If it last
too long, dust, vapor and other obstacles may enter the pipe and cause trouble later on.
Before connecting the pipe, the air in the pipe should be removed in advance by releasing
refrigerant R-410A.
Notes for the bendable pipe
a. The bendable pipe should be used on the indoor side;
b. Bend angel may not exceed 90 degrees;
c. The bend location should be made on the center of the pipe if possible, as for bend
radius, the bigger the better;
Page 18
15
d. The bendable pipe may not be bent for more than 3 times.
Bend the thin pipe
a. While bending, expose the pipe by cutting the concave gap on the bending
heat-insulation pipe(roll it with soft band after bent).
b. To avoid pipe deformation, the radius is the bigger the better.
c. Use a pipe-bending device to make the compact bending pipe.
5.3.2.3 Using bronze pipe selling in market
Completely shut the cut-off valves of the outdoor unit (as ex-work status). After t
he refrigerant pipe has been connected with both the indoor and outdoor unit, let th
e air exhaust out from the maintenance gap on he low-pressure cut-off valves of
the outdoor unit. Screw the nuts tightly on the maintenance gap after the air has
been drained.
5.3.2.4 To make the refrigerant pipe unblocked completely
You should keep the cut-off valves of the outdoor unit completely open after you
have finished the above steps (5.3.2.2 or 5.3.2.3)
Note:
1.Before screwing the reamer nut, smear the pipe and the connecting surface with r
efrigerant oil;
2.Check and make sure there is no leakage by soap-water or leakage-checker after
connecting;
3.Be sure the connecting joint on the indoor side is insulated.
4.Use two wrenches to connecting the pipes.

5.3.3 Installation for the first time
Air and moisture in the refrigerant system have undesirable effects as below:
● Pressure in the system rises.
● Operating current rises.
● Cooling or heating efficiency drops.
● Moisture in the refrigerant circuit may freeze and block capillary tubing.
● Water may lead to corrosion of parts in the refrigerant system.
Therefore, the indoor units and the pipes between indoor and outdoor units must be
leak tested and evacuated to remove gas and moisture from the system.
Gas leak check (Soap water method):
Apply soap water or a liquid neutral detergent on the indoor unit connections or
outdoor unit connections by a soft brush to check for leakage of the connecting points of
the piping. If bubbles come out, the pipes have leakage.
