Multiport (4 & 6 Way) Valve Operation - Waterco Exotuf E400 Manuel D'installation Et D'utilisation

Plumbing
1. Check that the incoming water pressure is within the filter's recommended working pressure and
ensure that a pressure limiting valve is installed if using mains water or a high pressure pump.
2. Ensure that a foot valve / non return valve is installed if the pump is installed 500mm / 20" above the
water level.
3. If the filter is installed below the water level or connected to mains water, isolation valves should
be installed at the inlet and outlet of the filter. This will prevent water flow during any routine
maintenance.
4. Minimise the length of pipe and the number of fittings to minimise restrictions to water flow.
5. Connect all plumbing to the Multiport Valve taking care that all plumbing connections are glued and
tightened securely to prevent leaking.
6. Ensure solvents are not excessively applied to fittings as this could run into o'rings and create sealing
problems.
7. Do not over tighten fittings or adapters.
Installation of the Multiport Valve
Top Mount Fibreglass Filters are supplied with either a Top Mount screw down Multiport Valve or clamp
down Multiport Valve.
Side Mount Fibreglass Filters are supplied with the option of a Side Mount Multiport Valve with a
plumbing kit designed to be connected to the side ports of the filter.
Each Multiport Valve is supplied three threaded barrel unions.
1. Check that the top of the filter is free from any filter media or debris and if there is a valve o'ring,
please check that the valve o'ring is in place.
2. Check the label of each valve port and position the valve accordingly. Pump port must be plumbed
to the pump discharge, waste port must be plumbed to the waste line and the return port must be
plumbed to the return line
3. Top Mount Screw Down Multiport Valve - Rotate the Multiport Valve into the filter vessel's threaded
connection.
Top Mount Clamp Down Multiport Valve – Align the valve with the top of the tank flange. Place the
clamp half over the valve flange and the tank flange. Insert the clamp screws and nuts in the clamp,
making sure that the nuts are located in the retainer slots on the clamps. Tighten the clamp screws
firmly and check that the valve and clamp are correctly assembled.
Side Mount Multiport Valve – Align the Multiport Valve's plumbing kit with the filter's threaded
connection ports. Screw the plumbing kit's barrel unions onto the filter connection ports and hand
tighten. Do not over tighten the barrel unions as this can lead to damage and void warranty.
4. Screw the Multiport Valve barrel unions onto the threaded connection ports of Multiport Valve and
hand tighten. The barrel union should be firmly threaded into the Multiport Valve and there should be
no play between the thread. Do not over tighten the barrel unions as this can lead to damage and
void warranty.
5. Glue the PVC pipe to the barrel unions and Allow 24 hours for glue (solvent) to set before starting the
filter.
6. Test the filter and check for leaks around the threads.
MULTIPORT (4 & 6 Way) VALVE OPERATION
1. Filter - Position for filtration.
Incoming water from the piping system is automatically directed by the Multiport Valve to the top of
the filter bed. As the water is pumped through the filter bed, dirt and debris are trapped by the filter
bed. The filtered water is returned from the bottom of the filter vessel, through the Multiport Valve and
back through the piping system.
2. Backwash - Position for cleaning the filter media.
Water flow is reversed by the Multiport Valve through the filter bed so that water flow is directed to
the bottom of the filter vessel and up through the filter bed, flushing the previously trapped dirt and
debris out the waste line.
3. Rinse - Position for flushing the filter system.
The water flow is directed by the Multiport Valve through the filter bed and out. This process settles
the filter media bed into place and ensures any dirt or debris is rinsed out of the filter, preventing dirt
or debris returning to the Swimming Pool / Spa.
NOTE: This position is not available on 4-Way Multiport Valves.
4. Waste - Position for bypassing the filter bed to waste.
The water flow is directed by the Multiport Valve straight to the backwash outlet, bypassing the entire
filter bed. This Multiport Valve position is used lower the water level or for vacuuming water with high
dirt loads.
5. Re-circulate - Position for bypassing the filter bed to the Swimming Pool / Spa.
The Mulitport valve recirculates water flow directly back to the Swimming Pool / Spa,
bypassing the filter.
6. Closed – Position for closing all flow to the filter.
The Multiport Valve can be closed to enable servicing of pump without draining the water from the
filter. This position is not to be used with the pump operating.
NOTE: This position is not available on 4-Way Multiport Valves.
!
Operation of the Multiport Valve or mode selection is to be always done with the pump switched off.
