3 - INSTALLATION INSTRUCTIONS

Install the unit in a chosen place on a flat firm surface.
During cold weather, it is recommended to bring the valve back to room temperature before
operating.
All plumbing for water inlet, distribution and drain lines should be done correctly in accordance with
legislation in force at the time of installation. Install without tension or bending stresses.
The distribution tube should be cut flush with the top of the tank. Slightly bevel the ridge in order to
avoid deterioration of the seal whilst fitting the valve (View sketch below).
Lubricate the distribution tube joint and the joint with a 100% Silicon lubricant. Never use other types
of greases that may damage the valve.
All soldering on main plumbing and to the drain line should be done before fitting the valve. Failing to
do so can generate irreversible damages.
Use Teflon® tape if necessary in order to seal between the drain fitting and the outlet flow control.
On units with by-pass, place in by-pass position. Turn on the main water supply. Open a cold soft
water tap nearby and let run a few minutes or until the system is free from foreign material (usually
solder) that may have resulted from the installation. Once clean, close the water tap.
Place the by-pass in service position and let water flow into the mineral tank. When water flow stops,
slowly open a cold water tap nearby and let run until the air is purged from the unit.
Plug the valve to a power source. Once plugged the valve may do a cycle on its own in order to go
to service position.
Fill approximately 25mm of water above the grid plate, (if used). Otherwise, fill to the top of the air
check in the brine tank. Do not add salt to the brine tank at this time.
Initiate a manual regeneration, bring the valve into « brine draw and slow rinse position » in order to
draw water from the until the blockage of the anti air valve; the water level will be approximatively in
the middle of the air check.
Open a cold water tap and let the water run in order to drain the air out of the circuit.
Bring the valve in brine refill position and let it get back to service position automatically.
Now you can add salt to the brine tank, the valve will operate automatically.
