During the connection of the indoor unit and BU module to the refrigerant pipe, never pull any joints of the
indoor unit and the BU module by force; otherwise the capillary pipe or other pipe may crack, which then
would result in leakage.
The refrigerant pipe should be supported by brackets, that is, don’t let the unit withstand the weight of it.
For the Super Free Match system, each pipe should be labeled to tell which system it belongs to avoid
mistaken inaccurate piping.

Leak Test
1)
Please make sure that the stop valves of the outdoor unit are closed during the operation.
2)
The leak test should be made by pressurizing nitrogen gas.
3)
Open the pressure reducing valve, pressurize the connection pipes to 1.0 MPa (10 bar) slowly, wait ten
minutes, and make sure that the pressure will not drop.
4)
Rise the pressure to 4.0 MPa (40 bar) slowly, wait 24 hours, and make sure the pressure will not drop.
5)
If the pressure does not decrease, the pipes have passed the test. Otherwise, look for where the gas leaks
from.
