Step 8

Assemble and attach bypass valve to the control valve. See Figure 3 if needed. Next locate
and assemble the 1” NPT connection fi ttings before attaching them to the bypass valve.
Use the appropriate method of connection to ensure a permanent connection. Please refer
to fi gure 5 to correctly assemble the connection fi ttings. Install the fi tting into the bypass
valve, attach the plumbing to the 1” NPT male connection fi ttings, hand tighten the fi ttings
nuts only. Make certain the water enters inlet and discharges through the outlet side of the
bypass valve. Arrows can be viewed on the bypass valve to confi rm the correct fl ow path. At
this time make certain the bypass valve is in the bypass position and leave in that position
until instructed to place in the service position. Refer to Figure 3 for proper operation.

CAUTION

To reduce the risk associated with property damage due to water leakage:

•

Do not

use a torch or other high temperature sources near fi lter system, cartridges, plastic fi ttings or plastic plumbing;

• On plastic fi ttings, never use pipe sealant or pipe dope.

Use PTFE thread tape only,

pipe dope properties may deteriorate plastic;

• Take care when using pliers or pipe wrenches to tighten plastic fi ttings, as damage may occur if over tightening occurs.

Fitting Installation Instructions
1) The installation fi ttings are designed to accommodate minor plumbing line and fi ttings.
2) Thread tape is the only type of thread sealant allowed to be used; the use of paste of any kind

will void the factory warranty. Do not let the connection fi ttings support the plumbing, properly
support the plumbing as required.

3) Slide the nut on fi rst (closed and against the threads), then slip ring onto the fi tting, ensuring it

set correctly in groove, then the O-ring last. Use Silicone lubricant to allow for easier insertion of
parts into one another.

4) Hand tighten the nut only, the use of pliers or wrenches of any type will void the factory warranty

and may cause damage to fi ttings and water will leak in your home or facility.

Use customer supplied fi ttings to adapt the drain line to the control valve. Support of the drain line is required to prevent damage to the drain line elbow which could
lead to a water leak in the dwelling. Suitable drain line material can be Copper, PVC or CPVC pipe or PE tubing can be used to adapt to the ¾ NPT threads on the drain
elbow for long or high drain lines. Use only thread sealing tape to seal the threads, hand tighten the threaded joint. To utilize polyethylene tubing as a drain line, remove
the supplied nut and fi nd the insert that was shipped in the parts kit box. Slide the nut over the polyethylene tubing and insert the sleeve into the tubing. Slide the end of
the tubing into the elbow, using your hand thread the nut onto the elbow and hand tighten only. No thread tape is required to seal the threads with compression fi ttings.
