How To Use “Push-In” Fittings (Collet)
CAUTION
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Ensure all tubing and fittings are secure and free of leaks.
• Do not install unit if collet is missing. Contact 3M Purification if collets are missing from any fittings.
This product is outfitted with user friendly Push-In connectors. Proper use of the connectors is shown in Figure 4. It is most
important that the tubing selected for use with these connectors be of high quality, exact size and roundness, and with no surface
nicks or scratches. If it is necessary to cut the tubing, use a plastic tubing cutter or sharp razor knife. Make a clean square cut.
Should a leak occur at a Push-In connector, the cause is usually defective tubing.
To
Fix:
1. Relieve pressure
2. Release tubing
3. Cut off at least 1/4” from end
4. Reattach tubing
5. Confirm connection is leak free
Installation of Filter Cartridges
Pre-filter Cartridge
A pre-filter cartridge that reduces chlorine from the feed water is required for proper operation of the TFS450 RO filtration system.
If installing the TFS450 RO filtration system without a pre-filter, pre-filter choices are listed in the table below. Select a pre-filter
that matches the anticipated maximum water volume that will be processed in no less than twelve months. The pre-filter must be
removed and replaced at that time. The TFS450 RO filtration system supplied with both pre-filter and final (post) filter includes the
HF-95 pre-filter cartridge listed in the table.
• Remove the red cap from the pre-filter cartridge.
• Align the tabs on the cartridge to the openings in the pre-filter head on the left side of the filtration system and push up to
insert the filter.
• Turn the pre-filter ¼ turn to the right until a click is heard, indicating that the filter is properly seated.

to downstream equipment and the second for installation on the tank line – and 15 ft (4.6 m) of ½” (OD) tubing to connect the membrane module to
the external storage tank. If the kit is not purchased, these components must be provided by the installer.
