Check that all connections are water tight.
IMPORTANT NOTE:
Before operating the product, it is strongly rec-
ommended to ush the pipe work to remove
any residues or debris remaining after instal-
lation. A purge kit is available for this purpose.
See below
A purging kit - A4556AA (not included) designed to ush out debris from the pipe-work after installation
is available from Customer Care (see section 18)
Sensor and solenoids must be connected and be operational before purging (see sections 7 & 8)
The following procedure should be used to ush the pipe work:
1.Unscrew and slide back shrouds, close both isolating valves.
2.Remove both maintenance carriers as described in section 13.1.
3.Screw the purge kit bodies into both sides of product. Screw elbows onto the ends of the purge kit
bodies.
4.Open isolating valves then place a hand in the sensor detection zone (to operate the valve).
Allow water to discharge into a receiving vessel.
Note: suitable tubing can be push tted onto elbows if required.
5.Once system has been purged, reverse this procedure.
