Installation Instructions

5. COMPLETE PLUMBING TO AND FROM

THE SYSTEM

Using the “Typical Installation Illustrations” on the

previous page as a guide, observe all of the following

instructions while you connect inlet and outlet plumb-

ing:

=

Be sure incoming, untreated water is directed to

the “UPFLOW INLET” port. It may be necessary to

plumb a crossover if the water pipe’s flow is from

right to left.

=

Be sure to install bypass valve(s).

=

If making a soldered copper installation, do all

sweat soldering before connecting pipes to the

included plastic adapters. Torch heat will damage

plastic parts.

=

Use pipe joint compound on all external pipe

threads.

=

When turning threaded pipe fittings onto plastic

fittings, use care not to cross-thread.

=

Support inlet and outlet plumbing in some manner

(use pipe hangers) to keep the weight off of the

system.

6. FLUSH PIPES AND TEST FOR LEAKS

IMPORTANT: To avoid water or air pressure damage

to system inner parts, be sure to do the

following steps exactly as listed:

a. Fully open two treated water faucets, one cold and

one hot, nearby the system.

b. Place bypass valve(s) into BYPASS position. On a

single valve, turn both handles perpendicular to

water flow (See Fig. 5). On a 3 valve system, close

the inlet and outlet valves, and open the bypass

valve (See Fig. 4).

c. Fully open the house main water pipe shutoff

valve. Observe a steady flow from both opened

faucets.

d. Close both faucets.

e. Check your plumbing work for leaks and, if any are

found, fix right away. Be sure to observe all instruc-

tions in the previous section, “Complete Plumbing

to and from the System”.

f. Turn on the gas or electric supply to the water

heater. Light the pilot, if applicable.

7. START UP PROCEDURE

a. Place bypass valve(s) into SERVICE position,

EXACTLY as follows:

=

Single Bypass Valve: Turn the outlet (marked

downflow inlet on head) handle parallel to water

flow. Slowly turn the upflow inlet handle parallel

to water flow, pausing several times to allow the

system to pressurize slowly.

=

3 Valve Bypass: Fully close the bypass valve

and open the outlet valve. Slowly open the inlet

valve, pausing several times to allow the system

to pressurize slowly.

b. Check all connections for leaks.

c. Fully open a cold water faucet, downstream from

the system, and allow 50 gallons (190 liters) of

water to pass through the system. This should take

at least 20 minutes. Close the faucet.

d. Snap the top cover back in place on top of the rim.
