5. The dedicated branch circuit must be used, and leakage protector with sufficient capacity must be installed.
• Qualification Requirements of Installer
Relevant qualification certificate must be obtained as per national laws and regulations.
• Indoor Unit I
nstallation
1. Fixation of wall panel and piping layout
In case of left/right water pipe connection for the indoor unit, or in case the evaporator interface of the indoor
unit and the horn mouth of the connecting piping cannot be extended to the outdoor side for installation, the
connector pipes shall be connected to the evaporator piping interface of the indoor unit in the process of horn
mouth.
2. Piping layout
During layout of connecting pipes, drain hose and connector wires, the drain hose and connecting wire shall
be placed at the bottom and top respectively. The power line cannot be twined with the connector wire. The drain
pipes (especially inside the room and mac
hine) must be ventilated with thermal insulation materials.
3. Nitrogen charging for pressure maintaining and leak detection
After the evaporator of the indoor unit is connected to the connector pipe (after welding), nitrogen more than
4.0MPa shall be charged inside the evaporator and the piping connected to evaporator with a nitrogen cylinder
(adjusted by a reducing valve). Afterwards, the valve of the nitrogen cylinder shall be closed, for leak detection
with soapy water or leak detecting solution. The pressure shall be maintained for more than 5 minutes, and then
whether the system pressure is reduced or not shall be observed. In case the pressure is reduced, leakage can be
identif
ied. After the leak point is handled, the steps above shall be repeated.
After the evaporator of the indoor unit is connected to connecting piping, nitrogen shall be charged for
pressure maintaining and leak detection. Afterwards, the evaporator shall be connected to the two-way stop valve
and three-way stop valve of the outdoor unit. After the copper cap of the connecting piping is fastened, nitrogen
more than 4.0MPa shall be charged at the access hole of the three-way stop valve with a charging hose. The valve
of the nitrogen cylinder shall be closed, for leak detection with soapy water or leak detecting solution. The
ssure shall be maintained for more than 5 minutes, and then whether the system pressure is reduced or not shall
pre
be observed. In case the pressure is reduced, leakage can be identified. After the leak point is handled, the steps
above shall be repeated.
The operation above can also be completed after the indoor unit is connected to the connecting pipelines and
the two-way stop valve and three-way stop valve of the outdoor unit, after the access hole of the outdoor unit is
connected to the nitrogen cylinder and pressure gauge and after more than 4.0MPa nitrogen is charged. No leak
points are identified in the leak detection at the joint/welding junction of the indoor unit and at the joi
nt of
connecting pipelines of the two-way stop valve and three-way stop valve of the outdoor unit. It must be
guaranteed that each joint is available for leak detection during installation.
The next step (vacuumizing with a vacuum pump) can only be continued after the installation steps (nitrogen
charging for pressure maintaining and leak detection normal) are completed.
