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.

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.

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.

Operating Procedures

Tap Operation

Boiling water

Zenith Autoboil is fitted with a two-way tap for filtered instant boiling water.

For instant boiling water, gently pull the top of the tap forward.

Boiling water will flow until the tap handle is released.

This operation gives fingertip flow control for safe filling of cups and mugs.

To fill larger vessels such as teapots and saucepans, rotate the tap 180 degrees and depress it until it locks into a horizontal position.

Boiling water will flow until the tap is returned to its normal vertical position. This operation allows the vessel to be filled without holding your hand where it may be affected by steam.
