Maintenance
 
Filter Changes 
NOTE: Filter life is 1500 
gallons or 12 months, 
whichever comes first. With 
higher usage, filter life may 
need to be replaced sooner. 
See your water dealer for 
more information. 
 
Step 1: 
Remove the top lid of the 
cooler. Unscrew the 3 
Phillips screws that hold 
down the internal lid and lift it out of place. This will expose the filter area. 
 
Step 2: 
Pull the filter out enough to unscrew the cartridge from the head. When the cartridge is free, 
move the head aside, pull the cartridge out and lower a new one in its place, screwing it firmly 
into the head. Lower the filter back into its place.  
Step 3:
The new filter cartridge must be purged before it is used. Shut off the inlet water supply and 
see Step 8 under the Installation section for instructions on how to safely do this. 
 
Step 4: 
Turn on the inlet water supply. Dispense water; check for leaks. Replace the covers 
removed in Step 1. 
 
Step 5: 
Note the date of filter change on the filter replacement sticker on the back of the unit.
