13. BRIVIS AD TIMING & COOLER FUNCTIONS
13.1 START - UP - BRIVIS AD MODEL WITH DUMP VALVE
The Cooler has been pre-programmed to automatically saturate the filter pads when the pump is turned ON (Pre-
Wet). The cooler will delay this Pre-Wet operation for a period of 4 minutes to allow the tank to fill with water (Fill-
Time)� This delay will only occur where the pump has been OFF for longer than 45 minutes�
13.2 PRE - WET
Pre-wet is the process of running the pump and wetting the pads without the fan operating, ensuring full pad
saturation and optimum cooling potential when the fan starts�
13.3 PROGRAMMABLE WALL CONTROL MODELS IN AUTO MODE
These models operate similar to Brivis Networker and Manual wall control models but in auto mode the Pre-wet
operates slightly differently.
If the Cooler has been OFF for longer than 15 minutes it will begin with a 2 minute Pre-wet, then turn OFF the
pump and start the fan�
Depending on the room conditions and the wall control setting the Cooler may perform another Pre-Wet (as
described above) when the pump is turned ON again, forcing the fan to turn OFF for that period�
13.4 SHUT - DOWN TIMES ( DUMP VALVE )
When the Cooler is turned OFF at the end of use the controls are programmed to wait 45 minutes before draining
the tank�
