MAINTENANCE 

1. Once a month during cooling season, inspect your cooler for leaks, blocked water lines and excessive residue build-up 

on the pads. 

2. At the end of the season, drain the reservoir.  Remove the drainpipe and let water and dirt pass through the drain fitting. 
3. Lime build-up can occur in the water reservoir and on louvers.  Clean this off at least once per season.  If any rust or 

bare metal spots occur on the cabinet or louver, the metal should be sanded, primed and painted with a good quality 
paint. 

4. If freezing weather occurs in your area, it is best to shut off the water supply at the source and drain the supply line to 

the cooler. 

5. A canvas cooler cover is recommended to prevent rain and weather from damaging your cooler. 
 

DO NOT GET WATER ON MOTOR OR PUMP MOTOR 

NOTE: 

Depending on the mineral content of the water or the amount of airborne dust in your area, you may need to 

replace filter pads during the season. 

It is best to replace filter pads again at the end of the season. 
Old filter pads soak up lime and salts, which can rust the louvers and the cabinet during the winter months. 

 
TO REPLACE PADS 

1.  Remove louver (U) from cooler

 

2.  Unhook pad holders (V) at the sides of the louver.  Unhook pad holders  

above and below side pads inside cooler. 

3.  Remove old pads (W) and discard. 
4.  Tuck in rear pad to make sure hot air can not by-pass filter. 
5.  Place pad holders over new pad and hook into place. 
6.  For the side pads, center pad over louver openings in cabinet, hook pad 

holder below pad, tilt into place and hook at top.
