ALTERNATIVE BLEED SYSTEM
During operation, the bleed system will drain
small amounts of water. This ensures fresh
water is continually added to dilute salt
accumulation in the water caused through
evaporation. This helps keep the air cooler in
good condition and ensure optimum
performance. The bleed rate will depend on
local operating conditions and will be set by
the installer.

Draining water from your air cooler at the
end of the summer season is not required if
your cooler is fitted with an automatic drain
valve. However, it is advisable to check the
