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.

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.

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.

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 tun dish to the wall as shown and plumb away to

waste.

Note: when routing the plumbing for the vent / tundish installed and

mains inletline, ensure you do not obstruct filter access for filter

replacement.

Remove Filter Guard

Vent line

Installation Procedures

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 ap-

plication.

Page 6 of 24 Zenith Autoboil - Installation & Operating Instructions - 804545NZ - 03.17 v1.00

3.3 Electrical

Warning: Do not turn on the power until instructed. Water must first

be available from the tap outlet to prevent damage.

For an exposed electrical connection, the pre-fitted flex and plug cable

is plugged into the PCB as shown. Use a standard GPO 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

concealed power cable through the rear access opening to the green

terminal block on the PCB.

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.

Problem Solving

Warning: this appliance must be earthed.

Following remedial service the earthing continuity of the heater must

be checked by a qualified technician using an appliance tester, or

continuity tester of accuracy Class 5 or better. Class 5 denotes an

accuracy of 5% full scale deflection.

1. Isolate power supply.

2. Set meter to 0 ohm with leads connected together.

3. Connect one test lead to the earth pin on the three pin plug.

4. Connect the other test lead to a bare patch of metal (preferably on

the edge) of the top of the cover, then to the front cover of the unit,

and then to the tap.

Warning- the water may be boiling - show extra care.

5. Test that in every instance the electrical resistance does not exceed

1 ohm.

Earthing Continuity Verification

If required, an earth continuity

test can be performed by testing

between the earth pin on the

products lead and a exposed

piece of metal on the case and

the tap body.

Symptom Possible Cause Solution

Fails to dispense water.

Incorrect filter flush valve setting.

Incorrect filter insertion.
