6.2 – MAINTENANCE
It is recommended that a evaporative cooler is regularly maintained. The frequency of maintenance
is dependent upon the quality of water, the cleanliness of the air and the frequency of use. In normal
conditions a 6 monthly service will maintain the reliability, efficiency and hygienic operation of the
cooler.
6.2.1 Preparing the cooler for maintenance
1. Ensure the cooler is fully drained by switching the cooler on in vent mode. Any water will then be
automatically drained.
2. Electrically isolate the cooler by using the external switch mounted on the underside of the cooler.
3. Remove the side panels by first removing the securing screws and then, by lifting the frame slightly
and moving it outwards, the side frame holding the pad can be removed. Take care not to damage
the top surface of the pad.
6.2.2 Cleaning the cooler
1. Clean all surfaces to remove any deposits.
2. Remove the water distributors and clean thoroughly
3. Remove the water pump and clean the impellor area
4. Clean water probes carefully
5. Clean the pads using low pressure water
Note on salinity setting: If there is evidence of scaling then the bleed rate should be
increased.
6.2.3 Pad
inspection
The pads should be replaced if
1. They are mechanically damaged
2. They are contaminated by airborne products so badly they cannot be cleaned using a low
pressure water pipe
3. They have salt or scale build up
4. Their efficiency has reduced to an unacceptable point
6.2.4 Pad replacement
1. Remove pad by lifting out of the side support frames.
2. Clean side frame thoroughly
3. Place new pad in side frame with distribution layer to the top.
