Manual Bypass Operation
In the event of failure of the main electronic controller, the unit can be run
temporarily in mechanical bypass mode. By
changing the position of the two manual bypass switches mounted in the cover of the controller electrical box from ‘0’ to
‘1’, the comp
ressor will run at 100% capacity – controlled by the adjustable LP switch (see page 21). In bypass mode, the
condenser fan will run without fan speed control.
Note: Please ensure the two bypass switches are always at “0” position
while running in electronic controller mode!
