Remove cover from distributor tube and brush any beads of resin out of
the threads in the neck of the vessel.
Unpack valve and skip down over the distributor tube. Screw the valve in to
the resin vessel, taking care not to cross the threads. Excessive force
should not be needed as the valve is running in to the vessel. Finally
tighten to approximately 20 ft/lbs torque. Adjust position of vessel to line
up piepwork connections, not the position of the valve on the vessel.
Position the brine tank and connect brine line to the bulkhead
connector above the overflow (3/8”). Ensure that a brass insert is placed
inside the brine line before connecting.
Connect inlet and outlet pipework to the valve (1” BSP 90 deg or straight
male threaded elbows at rear of valve) using flexibles where possible or rigid
high pressure pipe and socket unions. Some felxible pipework is
advisable to prevent stress on the vessel as it cycles during service, since
it will expand and contract longitudinally.
Connect drain line to the drain outlet (3/4” male threaded elbow on top of
valve). Ensure that there is an air break in the drain line at the same height as
the valves to prevent negative pressure on the vessel.
Connect brine line to the brine connection on the valve. Again ensure that a
brass insert is placed inside the brine line before connecting.
Connect power supply to valve and commission.
5.2 Options
5.2.1 No Hard Water Bypass
All Clack valves are fitted with Bypass pistons, they will pass regeneration
water to service if there is a demand during regeneration. If this is a potential
problem then it can be resolved by fitting a Motorised Alterating Valve (MAV)
with one port block or a No Hard Water Bypass Valve (NHWBV) on the outlet
of the valve. The two pin connector from the MAV or NHWBV has to be
connected to the ALTERNATOR DRIVE pin of the Clack valve and step 3CS
in the OEM programming level has to be set to nHbP. The MAV or NHWBV
will be driven to close before the first regeneration cycle that is not FILL or
SOFTENING or FILTERING and be driven open after the last regeneration
cycle that is not FILL.
