SLOWLY pour the support gravel into the tank. See the System Specification on page 1 for
the proper amount for your model.

Fill the tank with water, if possible.

Verify that there is a large tank O-ring on the control valve adapter base.

Thread the control valve onto the tank. Make sure that the distributor slides easily into the
riser O-ring and does not bind or cut the O-ring.
12.
Tighten down the control valve and verify that the orientation is correct to install the
plumbing.
13.
Connect the facility plumbing to the control valve inlet following all local codes. Temporarily
run the control valve outlet to drain at this time.
NOTE:
Be sure all piping is free of thread chips and other foreign matter.
14.
Pipe a drain line from the backwash flow control assembly to the drain. Use a minimum of
elbows and increase or decrease the pipe size to connect to the backwash flow control
assembly. Install a union near the backwash flow control assembly to facilitate cleaning, if
required.
DO NOT
install a valve in this line or use pipe smaller than listed in the Specification Table on
page 1.
DO NOT
make a direct connection to the drain. Provide an air gap of at least four times the
diameter of the drain pipe to conform to sanitation codes and to permit the observation of
the drain flow.
