Rinsing and Replacing the TAC Cartridge
(VZN-441H-T5 ONLY)
NOTE: Do not perform this procedure with a new Carbon
Element installed.
1. Turn off water to the system by closing the Inlet Ball
Valve and then close the Outlet Ball Valve.
2. Press the FLUSH button to initiate the flush cycle.
Repeat several times to ensure the permeate tank is
empty.
3. Press and hold the Red Pressure Relief Button on the
top of the TAC Housing (Figure 11) to lower the water
level inside the housing by 2 to 3 inches.
4. Remove the TAC Housing (Figure 10).
5. Empty any water into a drain and discard the old TAC
Cartridge (Figure 11).
6. Inspect the O-ring on the TAC Housing. Replace the
O-ring if it is cracked, twisted, or missing.
7. Lubricate the O-ring with an approved food grade
lubricant and install into the TAC Housing.
8. Install the new TAC Cartridge into the TAC Housing with
the arrow on the cartridge pointing up.
NOTE: Make sure the End Seal gaskets are in place in
the recessed grooves on both ends of the TAC Cartridge
(Figure 12).
9. Screw the TAC Housing (containing the TAC Cartridge)
into place on the TAC Head. The Housing will come
to a hard stop at the end of the thread. Use a Filter
Wrench if necessary.
10. Direct water from the Rinse Ball Valve to drain.
NOTE: It is important to direct the Rinse Ball Valve to a
drain as the water resulting from the flush should NOT be
used.
11. Turn on the water to the system by slowly opening the
Inlet Ball Valve and allow water to flow through the TAC
Cartridge and Housing to clear out trapped air and any
carbon fines that may be present.
12. To help remove trapped air from the TAC Housing,
press the Red Pressure Relief button on the top of the
Housing until water just begins to come out.
13. Rinse the TAC Cartridge for at least 5 minutes.
NOTE: Do NOT consume the water used for rinsing the
TAC Cartridge.
14. When the TAC Cartridge rinsing is complete, close the
Rinse Ball Valve and open the Outlet Ball Valve.
15. Reconnect the water to service. The system is now
ready for use.
