Zip Autoboil- Installation & Operating Instructions - 81439 - May 2012 v1.02
Step 3 – Connecting
a) Plumbing
For exposed plumbing connection, connect the cold water inlet pipe from the base
of the heater directly to the 1/2” or 12.7 mm compression fittings.
For concealed plumbing connections, connect the cold water pipe through the rear
of the chassis using a 1/2” or 12.7 mm capillary elbow (# 63 Swivel Elbows).
Cold water pipes must be flushed before connection to the inlet. Any clogging due
to sediment or fines will adversely affect the operation of the heater.
It is recommended that the heater be installed with a stop cock which allows it to
be isolated from the mains supply for servicing.
Water pressure requirements:
Minimum - 100 kPa maximum - 700 kPa.
Warning: If pressure is likely to exceed 700 kPa, a pressure limiting valve must be
installed in the cold water supply line. Zip recommends a valve rated at 350 kPa
for this application.
b) 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
1/2” or 12.7 mm 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.
c) Electrical
For concealed electrical connection, connect a power cable through the rear access
opening of the heater to the terminal block within the heater as shown.
For exposed electrical connection, run your circuit in adequately rated conduit
secured to the wall surface. Electrical access is from the rear left bottom edge of
the heater.
Do not turn the power ON until the heater is filled with water.
Step 4 – Assembling
Place the heater case back on to the heater and secure the top 2 case screws.
Secure two bottom case screws.
Fit the flow restrictor to the outlet spout of the unit by sliding it in until it’s shoulder
makes contact with the spout end. You may now fit the tap assembly.
Step 5 – Commissioning
Check previous steps. Turn water supply ON. Water is now flowing into heater,
check connections for leaks. Wait approximately 5 minutes and check outlet tap
for water. This is acheived by pulling the tap handle forward. Power is only to be
turned on when water is available from this outlet.
Turn power ON. After a short period, boiling water will be available and will be
maintained close to boiling point thereafter. Initial heating periods are shown in
the table on the left. In 25 and 40 Litre models there is a contactor fitted, when
engaging or disengaging the heating cycle you will hear the contacter “kick in”.
