Cartridge Replacement Instructions - ONE CW-840-1 Installation Instructions & Owner's Manual

CARTRIDGE REPLACEMENT INSTRUCTIONS FOR CW-840-1
1. Turn off water supply to vessel using bypass inlet and outlet lines.
See page 4 for bypass diagrams.
2. Release pressure on system by opening bottom drain for a moment, then close. If bottom
drain is not installed, turn off water to inlet side of filter and open an outlet line to the
filter.
3. Disconnect bypass from valve assembly using the nuts at the inlet and outlet head
assembly (see Fig. 1). Be careful not to disconnect the nuts at the plumbing lines as these
are under pressure.
4. Remove retaining ring which holds top cap in place (see Fig. 2). Push down on top cap
equally to unseat the ring. To remove, pull on retaining ring handle by pulling inward and
then upward. This will release ring from grooved seal.
CAUTION: Do not remove retaining ring without relieving pressure from system.
5. Remove top cap by pulling upward on head assembly.
6. Carefully remove old cartridge from system (see Fig. 3). The cartridge will contain water
and will splash or drip. Place used cartridge into a 5 gallon bucket to protect area from
water damage.
7. Remove new cartridge filter from box and remove plastic covering. Locate product
description tag and keep for future use.
8.
Lubricate O-ring in valve assembly to ensure proper sealing (see Fig. 4).
Do not use pipe dope, Vaseline, oils or other unacceptable lubricants on O-rings.
Food grade silicone lubricant is recommended.
9. Place cartridge into filter housing with "distributor riser" at the top of the tank
(see Fig. 5).
10. Carefully replace top cap assembly making sure that the adaptor slips into the
top cap assembly. Push down on head assembly firmly. This will make room for
replacement of ring assembly (see Fig. 6).
11. Attach product description tag to retaining ring for future reference (see
Fig. 7). Insert retaining ring into ring groove, starting at the end opposite of the
handle. Gently push retaining ring into groove until the entire ring is in place
and both ends meet in the groove section. To ensure proper engagement, hold
retaining ring by handle and slightly rotate around the inner diameter of the
cartridge tank.
12. Reconnect cartridge tank to bypass valve by securing nuts.
13. Open a treated water line and turn bypass valve to the service position
(Fig. 1 on page 4) and allow water to fill tank slowly. Once water is flowing to
treated water faucet, observe tank for any leaks.
14. Shut treated water line off to check for leaks and ensure system integrity.
