Cartridge Conditioning

The activated carbon, reverse osmosis, and polishing filter cartridges must be conditioned as follows
prior to installation into the Culligan Water Tower™ drinking water system. Your Culligan Man™ can
do these important procedures at the time of purchase.
Activated Pre-Carbon Filter Cartridge - 2 gallon flush to remove carbon dust
RO Membrane Cartridge - 24 hour flush to remove preservative solution
Activated Post-Carbon (Polishing) Filter Cartridge - 2 gallon flush to remove carbon dust
Tubing Connectors
The Culligan Water Tower drinking water system features easy-to-use push-in tubing connectors
(Figure 3). Fittings consist of two parts: a body and a colored collet. Collet color corresponds to tub-
ing color to be used at that connection (Figure 3A).
1. To install a tube, lubricate the tubing end with water (only) and push it through collet until it
seats firmly at bottom of fitting (Figure 3B). You should feel the tubing pass the O-rings. Cut
ends must be square. Be sure the tubing is smooth and free of abrasions, otherwise a leak may
result. Cut tubing only with a new razor blade.
2. To remove a tube, push and hold the collet against the fitting body and pull the tube from the
fitting. (Figure 3C).

Cartridge Replacement, Cleaning and Sanitizing Procedure
1. Mix a mild cleaning solution of dish soap and clean potable water in plastic bowl.
2. Empty storage tank and relieve system pressure. Verify tank valve is open. Close feed water sup-
ply valve and open product water faucet.
Note: Additional point-of-use devices (i.e. icemakers) may use filters along their supply line.
Remove any filter or treatment device installed between module and delivery device before pre -
ceding.
Icemaker: Transfer ice cubes from bin/tray to clean freezer container for storage until procedure
is done.
3. Check product water storage tank air pre-charge using low-pressure gauge (PN 34002024). Air
valve is located on tank base. Pre-charge should be 55 kPa (8 psig) with tank empty and tank
valve open.
