Cooler Operation:
(cont.)
Wash Service
When the Networker is turned OFF, at the end of use, or the pump and fan have
been OFF for more than 60 minutes, the ServoSeal closes (Contours) and the drain
valve lowers to drain the tank water.
Following the ServoSeal closing, the Cooler will automatically perform a tank washing
action, after the time delay allowed for closing the ServoSeal ServoTime (20
seconds).
A further 45 second delay (WashWaitTime) allows time for the tank to be drained
completely, and initially wash out any sediment from the tank.
With the drain valve still in the lowered position, the water inlet solenoid is opened for
30 seconds (WashTime), allowing clean water to further flush sediments from the
tank base.
On completion of the wash, an additional 45 second delay applies, before any other
(new) operation can be performed i.e. Networker turned back ON again.
The Cooler then remains idle until the Networker is turned ON again, and calls for
cooling.
