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.
