Read These Warnings First
Please read all installation requirements, installation procedures and
precautions before installing any Zenith Autoboil instant boiling water
heater.
Never attempt to install any Zenith Autoboil instant boiling water heater
without reading all of the applicable instructions.
In some hard water areas where mineral scale accumulation in the boiling
chamber of the Zenith Autoboil may become a problem, consideration
should be given to the maintenance required. A suitable form of water
treatment may be necessary.
The cold water supply to this appliance must be potable and fall within your
local authority’s guidelines.
All plumbing connections must be made in accordance with local
regulations.
The Zenith Autoboil instant boiling water heater is not intended for use by
young children or infirm people without supervision.
Young children should be prevented from having access to ensure that they
are not able to use or play with the heater.
This appliance must be earthed. If the power supply cord is damaged it
must be replaced by a Zenith authorised agent or a qualified electrician.
Do not remove the cover of the heater under any circumstances without first
isolating the heater from the power supply.
Do not use strong, corrosive or abrasive cleaners to clean the case of the
heater.
Frost protection: If this heater is located where ambient air temperature
could fall below 5ºC when the heater is not in use, do not turn off the
appliance electrically. This safeguide does not offer the same protection to
the connecting pipework and fittings.
The ambient temperatures this unit must operate within is 5ºC - 50ºC.
This heater is intended only for indoor use and should never be installed
outdoors or be exposed to the elements of nature.
This unit must not be positioned in an area that may be cleaned by a water
jet. This unit must not be cleaned by a water jet.
Installation Requirements
Before installing, ensure that the following are available:
a) Sufficient space to position the heater so there is at least 100 mm
clearance above the heater for service access, 150 mm to its left and
20 mm to its right – the tap outlet must be positioned at least
300 mm above a draining board or drip tray.
b) Standard 220- 240 volt power cable positioned as shown on the paper
mounting template for connection from the rear of the heater to the
terminal block within the heater, OR a standard 10 amp 220- 240 volt
power outlet on the wall within 1500 mm of the heater. This switch must
provide all-pole disconnection and a contact separation of at least 3 mm
installed in accordance with wiring rules, see Step 3 - 3.3).
c) Cold water supply with a minimum working pressure of 70 kPa and a
maximum working pressure of 700 kPa connected via an isolation valve.
d) Outlet drainage to a sink draining board or to a drip tray.

e) Access to drainage from a vent situated at the base of the heater.
f) If the water pressure is likely to exceed 700 kPa, a 350 kPa pressure
reducing valve must be installed in the cold water supply line.
f) In all installation instances the walls of the heater must be vertical and
the base horizontal, there can be no exceptions to this rule.
Installation Procedures
Before You Begin
Refer to the mounting-hole template on page 17.
Read the installation and operating instructions completely.
Decide whether to install with concealed or exposed plumbing and/or
electrical connections. Concealed connections are preferred for superior
appearance.
Step 1 – Positioning
Position the heater so the tap will drain on to a draining board or drip tray.
Position the base of the tap to be not less than 300 mm above the
draining board (height should be increased only if essential for filling larger
vessels).
Provide clearance for service access of not less than 100 mm top, 150 mm
left, 20 mm right.
Mark corner positions for the heater on the wall so as to position the paper
mounting-hole template.
Step 2 – Fastening
Position mounting-hole template on wall and drill holes where shown.
Remove cover fastening screws from heater and lift whole cover off heater.
Remove filter guide as shown in picture above.
Install plumbing and wiring and prepare pipe ends and wiring ends as
shown.
Screw heater chassis to the wall using screws or bolts suited to the wall.
Screws or bolts must be capable of supporting the heater weight when
filled.

Warning: If pressure is likely
to exceed 700 kPa, a pressure
limiting valve must be installed
in the cold water supply line.
Zenith recommends a valve
rated at 350 kPa for this application.

Remove Filter Guard
Step 3 – Connecting
THE FOLLOWING PROCEDURE IS TO BE DONE BY AN AUTHORISED
INSTALLER ONLY.
3.1 Plumbing
For exposed plumbing connection, connect the cold water inlet pipe from the
base of the heater directly to the 12.7 mm compression fittings.
For concealed plumbing connections, connect the cold water pipe through
the rear of the chassis using a 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 - 70 kPa maximum - 700 kPa.
3.2 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 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 visibly discharges to a waste
water drain.
Alternatively attach a tundish to the wall as shown and plumb away to
waste.
Vent line

Visible Tundish
Note: when routing the plumbing for the vent / tundish installed and mains
inlet line, ensure you do not obstruct filter access for filter replacement.
Installation Procedures
3.3 Electrical
Warning: Do not turn on the power until instructed. Water must first be available from the tap
outlet to prevent damage.
This unit is designed for connection to a 220-240 volt AC
power supply via either a concealed electrical connection or
an exposed electrical connection.
For an exposed electrical connection, the pre-fitted flex
and plug cable is plugged into the PCB as shown. Use a
standard 10 amp, 220-240 volt power outlet within 1500
mm from the heater with adequate power for the unit.
For a concealed electrical connection, disconnect the
pre-fitted flex and plug cable at the PCB connector and
discard. Connect the Live (Active) and Neutral wires of the
concealed power cable through the rear access opening to
the green terminal block on the PCB. Crimp a 6.3 mm QC
female spade connector to the earth wire of the concealed
power cable and attach to the chassis earth male terminal.
For a concealed electrical connection, an isolation switch
should be installed.
Check that the earth is connected through the PCB to the
chassis with an ohm meter.
Warning: Do not connect both options. It is essential that the flex and plug cable is removed
from the PCB if the concealed connection is used. Otherwise the GPO plug will become live.
Step 4 – Installing Filter Guide
Assemble the lter guide provided with the unit, make sure it is locked in position, then put the cover back on.
1. Push the lter guide upwards 2. Rotate clockwise until locked
Step 5 – Installing Tap

4. Use the spanner supplied to tighten the lock nut
anti-clockwise.
Step 6 – Installing Filter
To install a lter, insert the lter into the base of the unit as shown and turn 90° until a click or stop point is reached, see
images below. There should be approximately 20mm of the lter protuding when installed.

1. Insert the lter
2. Turn the lter through 90° until
fully engaged
NOTE: For safe operation, the filter cartridge should be replaced every 6-12 months, or earlier if you notice a
persistent reduction in water pressure from the appliance or an unpleasant taste or odour in the water. Refer to
Filter Replacement section on page 21 for instructions of changing lter.
Step 7 – Commissioning - Filter Flush & Calibrate
Warning: Do not turn on the power until instructed.
Water must first be available from the tap outlet to
prevent damage.
1. The filter flush valve switch is located on the left side of the
unit. Check that it is in the correct position to perform a filter
