Table of Contents

Note: The ScaleGard LP Reverse Osmosis Water Filtration System requires a minimum 50 psi inlet water

pressure. If inlet water pressure is less than 50 psi, a water booster pump may be required. Refer to Figure 1

for proper tubing connections.

All connections are made with "Push-In" connectors. Refer to Figure 2 on the use of "Push-In" plastic fittings. Use

care in routing the tubing to ensure that there are no bends or kinks.

1) Shut off water supply and water booster pump (if applicable).

2) Insert the 1/4" x 1/4" Stem X Barb Adapter (See Figure 1) into Inlet Water Valve. Run a 1/4" I.D. hose from the

Water Supply or Booster Pump to the Inlet Water Valve.

3) Insert one end of the 3/8" blue tubing (included) into one end of the outlet tee on the RO system and the other end

to one side of the Water Sample Valve Assembly. See Figure 1.

4) Insert the 3/8" x 1/4" Stem x Barb adapter into the open 3/8" port of the sample valve assembly. Run a 1/4" I.D.

hose from the water sample valve assembly to the inlet of the Foodservice Equipment. See Figure 1.

5) Remove the white plug from the bottom port of the RO Module.

6) Remove the red cap from the RO module and moisten the o-rings with water. Insert the cartridge into the filter

head. Be sure the ears on the cartridge line up with the spaces in the head. Then turn the cartridge 1/4 turn to the

right.

7) Connect the 1/4" red tube from the "Brine In" side of the permeate pump to bottom port of the RO Module. (See

Figure 3).

8) Run the separate 1/4" red tubing (included) from the "Brine Out" port of the permeate pump to the drain.
