FOR COOLERS WITH WATER
MANAGEMENT SYSTEM FITTED
The following is a description of the Prewet
function that occurs when COOL is selected
for the first time by the MagIQtouch Controller.
This ensures the pads are wet before the fan
(blower) starts.
1. Drain Valve Closes.
2. 9 seconds after drain valve closes the inlet
solenoid valve energises allowing water to
enter tank.
3. The cooler electronics will now wait up to 8
minutes for water to reach the probes. If the
water level has not reached the probes in
that time then a fault code (02) is initiated
(tri-coloured LED will flash red twice) and the
cooler will shut-down.
When the probes recognise water, the RED
LED (Right Hand LED on the cooler electronics
Box or “SAL” LED on the ICON Control Box)
will start to flash.
