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.
The example of the method of choosing capacity number:
1) If the unit is in high-speed operation, needing take outer static pressure is 180Pa in capacity air volume 34m
condition 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
condition point, according to Figure II “The characteristic chart of air volume”, the capacity number of fan controller is No. 4.
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.
