The performance of the heat exchanger degrades due to a buildup of dirt.
Clean the heat exchanger periodically. The cleaning interval depends on
the installation environment. So, clean the heat exchanger at appropriate
intervals according to the level of dirt built up.
WARNING
High voltage is applied to the heat exchanger of heat pipe
type. Before maintaining the heat exchanger of heat pipe
type, always turn off the power to the CNC.
When opening the cabinet and replacing a heat exchanger
of heat pipe type, be careful not to touch the high−voltage
circuits (marked and fitted with an insulating cover).
Touching the uncovered high−voltage circuits presents an
extremely dangerous electric shock hazard.
