Applicable to Systems in Non-Surface Water
Applications Only:
Connect the inlet and outlet fitting assemblies to the 3/4"
MNPT ends of the new plumbing with the supplied stainless
steel flex hoses.
Applicable to Systems Equipped with the Surface Water
Option Kit Only:
Select a location on an adjacent wall, with adequate support
(e.g. wall studs), between the stainless steel flex hose of the
inlet fitting assembly and the inlet line of the new plumbing.
Follow the instructions described under the Surface Water
Option Kit Installation section in this manual to install the
external prefilter. Connect the stainless steel flex hose on the
inlet fitting assembly to the external prefilter. Once finished,
connect the external prefilter to the 3/4" MNPT end of the new
inlet plumbing.

the system base.

To level the system, insert the supplied shims beneath the feet
of the system base. Check with a level. Once leveled, fasten
the system to the floor with the supplied 1/4" x 2-1/2" anchors
(for concrete floor) or use screws (not supplied) for wood floors.
NOTE:
If the system is being installed on a heated floor, use a
2' x 2' patio stone, that is securely anchored to the floor, for a
base. Do not drill the floor.

Apply plumber tape to the 1/4" threads on the air relief
valve. Using a hex key, remove the plug that is located at
the top of the system cap. Thread the air relief valve into the
opening. Do not use tools to tighten the air relief valve to the
system cap as it may cause damage. Loosen the black cap of
the air relief valve 1-1/2 turns to allow for proper venting. Do
not use pliers to take out plugs.
Inlet Fitting Assembly:
Follow the instructions in the Pipe Assembly and Installation
section to assemble the inlet fitting assembly. If the surface
water option kit is installed, rotate the inlet solenoid valve
right-side-up.
Final Plumbing Assembly

Fasten a drain hose to the nylon elbow of the drain
solenoid valve. Run the drain hose to a floor drain, sink or
dedicated drain that can accommodate the pressure and flow
created during a flush/drain cycle. The drain hose must be free
of kinks and leaks. Fasten the hose to the floor or wall and
direct the hose into the drain with an elbow or clamp. Ensure
that the drain hose can withstand the pressure of the home’s
water supply.
Drain hose must be
anchored down to the
floor or wall and
directed down into the
drain
The local plumbing
code may require
an air gap to be
installed at the
drain line.

All systems will have a pressurized flush sequence during the
cleaning cycle. Depending on the controller program selected,
the system may also have a draining sequence. Refer to the
Setting the Controller section for detailed information on
flushing and draining cycles. The following are recommended
drain line discharge set-ups for the systems.
NOTE:
Drain configuration must comply with the local
plumbing codes.
