11. Refrigerant pipe
[The air side pipe, liquid side pipe must be faithfully heat insulated, if no heat insulation, it may cause water leakage.]
The outdoor unit has been charged with refrigerant.
When connect the pipe to the unit or dismantling the pipe from the unit, please follow the figure shown,use spanner
and torque spanner together.
When connect cone nut, the inner side and outside of cone nut should paste with refrigerant oil. Use hand to twist 3-4
rings, then fasten with spanner.
Referring to Table I to confirm the fasten torque. (too tight may damage nut leading to leakage)
Check if the connection pipe leaks, then do heat insulation treatment, as below figure shown.
Only use seal cushion to bind the joint part of air pipe and heat insulation parts.
10. The operation method of fan controller
Through the fan controller switch in the electric box, the air volume of this unit can be continuously adjusted.
It is unnecessary to adjust air volume through the duct side wind level (unit outside static adjustment).
The air volume set should be in the operation air volume range.
Figure I shows the position of fan controller in the electric box and operation method.
After finishing the electric work, perform test run. According to the main points in Figure II making the chosen switch No.
accordant. And confirm if it reaches the needed air volume.
Note:
1) When operating the fan controller, it is possible to touch the electric charging part, so do cut off the power supply.
2) Do not set the dial at the position less than 1.
3) The figure circled in Figure II indicate the capacity number of fan controller. The non-listed capacity number may exceed
the permitted operation capacity range, so it is impossible to operate.
4) When delivering from factory, the capacity number of fan controller is set at No.5.
Rotate this switch
(capacity number
setting:
No. 1 ~ No. 8)
Once the fan controller
has trouble, this linker
can perform emergency
assistant control. When
this linker is connected
to the linker from the
PCB, it can operate with
total load.
When this linker is
connected to the linker
from the PCB, through
the fan speed adjustment
panel to adjust speed.

point, according to Figure II The characteristic chart of air volume, the capacity numberof fan controller is No. 2.
2) If the unit is in low speed operation, needing take outer static pressure is 60Pa in capacity air volume 32m
