MOUNTING

1) Remove the mounting bracket template from this manual. Tape it to the wall where the mounting bracket is to be
installed.

2) Install mounting screws (not included) into each of the keyhole locations on the template. Be sure to leave a 1/8”
to 1/4” space between the bottom of the screw head and the wall so that the bracket can be hung. NOTE:

Mounting hardware must be capable of supporting a minimum of 50 lbs (22.7 kg).

3) Hang the Bracket/Tank Assembly from the mounting screws.

4) Once the bracket is hung, tighten the mounting screws so that the bracket is snug between the screw and
the wall. Note: Make sure that the bracket is securely mounted to a wall stud or other appropriate wall

structure.

PLUMBING CONNECTIONS

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.
