9. TIMING & COOLER FUNCTIONS
9.1 START UP
Brivis Cooler with Dump Valve fitted will have a 15 second delay on start up.
On start up, the Brivis C Series ServoSeal damper will also open before any other function�
If the Cooler has been OFF for longer than 60 minutes the tank will require refilling. Allow approximately 3-5
minutes depending on the water pressure�
9.2 PRE-WET
The Cooler has been pre-programmed to automatically saturate the filter pads when the pump is turned ON.
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�
Pump Off Time
Pre-wet Time
Less Than 2 minutes
No Pre-wet
Between 2 and 10 minutes
Pre-wet 1 minute
Longer than 10 minutes
Pre-wet 4 minutes
Longer than 60 minutes
Tank has to be filled, therefore total time
including Pre-wet is 5 to 7 minutes
9.3 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 previously) when the pump is turned ON again, forcing the fan to turn OFF for that period�
9.4 TANK WATER QUALITY AND REPLENISHMENT DURING OPERATION
During the Cooler’s operation with the pump operating, the Cooler will be evaporating water from the tank and
automatically refilling itself.
Brivis Advance and Brivis Promina Series models will periodically, after a specified number of tank refills, flush out
the tank (discharging water from the drain outlet for approximately 1 minute) without stopping the Cooler�
How frequently this flush occurs will vary according to local water conditions and the rate of evaporation.
NOTE
Brivis Contour Series will not flush as often, as they are fitted with an AquaSave.
9.5 SHUT-DOWN TIMES
When the Cooler is turned OFF at the end of use, the controls are programmed to wait 60 minutes before
commencing Shut-down�
This Shut-down procedure starts with draining the tank (approximately 60 seconds)� Brivis Contour Series models
will also close the ServoSeal damper at the start of the Shut-down procedure� Then a wash cycle is performed to
clean the tank for approximately 30 seconds�
