A. Location
The system should be installed over a sink draining
board or over a bench top equipped with a portable
or plumbed drip tray. Tap outlet clearance to sink
should be no more than 200 mm unless pot lling
requires greater. Service access clearances must be
at least 150 mm above, 65 mm to left, 20 mm to right.
The vent within the case must discharge to a safe
visible position as, under certain conditions, the vent
may discharge cold water, boiling water, and/or steam.
The vent pipe outlet must be connected via a tun
dish to a 12.7 mm OD copper vent pipe which has a
continuous fall, is no more than 3 metres long, and has
no more than 3 right angle bends.
B. Electrical
The system should be plugged to a 10 amp GPO
delivering 220–240 V AC 50 Hz within 1500 mm.
For a neat concealed electrical connection, you can
connect cable from the rear directly to the internal
terminal block. Installation must comply with current
AS/NZS 3350 wiring regulations.
C. Plumbing
The system must be installed by a qualied
tradesperson and in accordance with the instructions
supplied with the system and AS/NZ 3500 plumbing
regulations. The water supply must be potable
(drinkable) and deliver at least 2 litres per minute
at a minimum dynamic pressure of 100 kPa.
A 350 kPa pressure reducing valve must be installed
if water pressure is likely to exceed 700 kPa.
An isolating valve must be installed between the water
supply and the system. For a concealed plumbing
connection, connect inlet and vent pipes from the
rear via 12.7 mm capillary elbows as shown.
For an exposed plumbing connection, connect inlet
and vent pipes from the base of the case directly
to 12.7 mm compression ttings.
Installation is as simple as A-B-C
