STEP 1:

Carefully remove all components from packaging. DO NOT DISCARD PACKAGING until all

backwash system components and fittings have been located.

STEP 2:

Place unit at desired installation position. Be sure the location is within 15 feet of a drain that is

lower than the control valve and near a non-switched electrical outlet. Also, ensure the tank is

on a level and firm base. Install the unit with at least 10 feet of piping before the water heater

to prevent hot water from backing into the filter. Turn off the main water supply and drain the

system.

STEP 3:

With the backwash filter unit in the upright position, remove the control valve from the

mineral tank being careful to not pull the distributor out of the gravel at the bottom of the tank..

STEP 4:

Cover the top of the distributor tube with the included red cap and, using the included blue

media funnel, pour filter media(s) (purchased separately) into the mineral tank. If using

multiple filter media types, load in the order of heaviest (most dense) to lightest (least dense).

12" – 14" of space MUST be left empty at the top of the mineral tank to allow for media bed

expansion during backwash and to prevent filter media from being discharged through the

drain line.

STEP 5:

Use a garden hose or bucket to fill the media tank with water.

IMPORTANT: Carbon, Filter Ag, Zeolite and Birm must be soaked for at least 2 hours

prior to submitting it to full backwash flow rate to prevent loss of media to drain.

STEP 6:

Clean mineral tank threads to remove any filter media. Remove red cap from distributor tube

and reinstall control valve by threading it securely onto the mineral tank. (O-ring seal; HAND

TIGHTEN ONLY!).

STEP 7:

If not factory installed, use the clips and screws provided and attached the bypass valve to the

inlet/outlet of the control valve. See Figures 2, 3, and 4 below.

pressure tank. Make certain pressure is relieved from complete system by opening nearest

faucet to drain system. SHUT OFF FUEL / ELECTRICAL SUPPLY TO WATER HEATER.
