5.11 Ventilating the pump
Immersion pumps are self cooling. Ventilating the pump is not necessary.
ADVICE:
During the initial start up of the chiller, the pipes and the laser modules
will begin filling with water. This will cause the water level to fall.
Make sure, that water according item 5.6 is available so that you can
refill the tank when necessary.
The water level inside the tank will be controlled by level indicators. If the
water level is too low, the chiller will be switched off.
