13.2 Maintenance
WARNING
Disconnect the 4 pin pump connector from the cabinet when servicing or
whenever the cooling circuit is opened to prevent accidental power-up of
the pump with the controller.
Make sure that the controller cabinet is powered off and unplugged from the
power source. Follow lockout / tagout procedures.
13.2.1 Drain the Coolant
CAUTION
Make sure that the E-Multi injection unit is flushed and completely purged of
water.
Disconnect the pump before you empty the reservoir. Failure to do so will
damage the pump if it runs dry.
CAUTION
1. Blow the compressed air into the supply hose of the E-Multi and drain the
coolant into the reservoir.
2.
Unscrew the drain plug as shown in the figure below and drain the coolant
from the reservoir.
