b) Filtration
Fasten filter head assembly to an under-sink internal cupboard wall
as closely as possible to directly beneath the heater.
The filter should be positioned where it can be accessed readily for cartridge
changing. Allow 300 mm clearance beneath the filter for ease of access.
Fit an isolating valve (not supplied) to the water supply and connect to the
double-non-return valve (supplied).
Trim a length of quarter-inch flexible tube (supplied) to connect the outlet on
the double-non-return valve to the inlet on the filter head assembly. If
necessary fasten the tube to the wall with cleats provided.
Unpack the filter cartridge and write the date where shown on the label.
Avoid handling cartridge top whilst inserting into head.
Align cartridge tabs with the slots on the under-side of the filter head.
Slide cartridge up into head and rotate left to right one quarter turn until it
stops.
Fit the balance of the quarter-inch tube (supplied) to the outlet of the filter. To
purge air from the filter cartridge, run the tube to drain in the sink. Open the
isolating valve, and run water through the filter (into the sink) for 2 minutes or
until water flows freely.
Note:
Freshly installed filters may cause water to appear milky. Water should
clear after running a few litres through the filter.
Turn isolating valve OFF and remove quarter-inch tube from the sink drain.
For superior appearance, fix a chrome plated tube between the sink top and
heater underside as a conduit for the flexible tube.
Trim the quarter-inch tube (supplied) to connect from the outlet of the filter
head assembly to the inlet of the 15 mm-to-quarter-inch reducing bush on
heater inlet. Fasten tube to wall using cleats provided.
Purging procedure
To purge air from a new filter cartridge, disconnect the quarter inch tube from
the outlet of the filter head, connect a temporary tube to drain into the sink,
and use the isolating valve to run water through the filter for two minutes or
until the water runs clear. Disconnect temporary tube and reconnect.
c) Venting
A vent at the base of the heater must be plumbed to a safe visible location as,
under certain conditions, it may discharge cold or boiling water and/or steam.
For exposed vent plumbing, connect vent outlet from the base of heater to a
15 mm or half inch OD pipe which has a continuous fall, is no more than 3
metres long, has no more than 3 right angle bends, and discharges to a waste
water drain.
For concealed vent plumbing, connect plumbing to the vent outlet from the
heater rear using a capillary elbow protruding 45 mm from the wall.
Alternatively attach a tun dish to the wall as shown and plumb away to waste.
