Read These Warnings First

Please read all installation requirements, installation procedures and
precautions before installing any Autoboil instant boiling water heater.

Never attempt to install any 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 Autoboil may become a problem, consideration should be
given to the maintenance required. A suitable form of water treatment may be
necessary.

All plumbing connections must be made in accordance with local authority
requirements.

The 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.

If the installation site is located more than 1000 meters above sea level, the
installer should contact The Zenith Heaters Limited service dept. to obtain
alternate PCB settings.

If the power supply cable is damaged it must be replaced by a Authorised
Service Provider 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 safeguard does not offer the same protection to the
connecting pipework and fittings.

The ambient temperatures this unit should operate with 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.

Before installing, ensure that the following are available:

a) Sufficient space to position the heater so there is at least 150 mm

clearance above the heater for service access, 65 mm to its left and
20 mm to its right – the tap outlet usually should be positioned at least
200 mm above a draining board or drip tray.

b) For units with 2.4 Kw element (15 ltr) standard 10 amp 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. For units with 3.6 Kw element (25 ltr) or multi element units (40
ltr) an isolating switch in the fixed wiring and attached to a secure surface
is required. This switch must provide all-pole disconnection and a contact
separation of at least 3 mm installed in accordance with wiring rules.

Installation Requirements

Page 4 of 12 Autoboil - Installation & Operating Instructions - 81355 - May 2012 v1.01

c) Cold water supply with a minimum working pressure of 100 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) In all installation instances the walls of the heater must be vertical and the

base horizontal, there can be no exceptions to this rule.

Note: 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.

Before you begin

Locate the paper mounting-hole template packed with the heater.

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 a superior
appearance.

If the heater is used for filling cups, then insert the flow restrictor into the
outlet pipe before securing tap assembly.

Step 1 - Positioning

Position the heater so the tap will drain onto the draining board or drip tray.

Position the base of the tap to be not less than 200 mm above the draining
board. ( height should be increased only if it is essential to accommodate larger
vessels.)

Minimum clearances for service are 150 mm top, 120 mm left and 20 mm
right.

Mark corner position on wall so to position mounting-hole template.

Step 2 - Fastening

Position mounting-hole template on the wall and drill mounting holes where
shown.

Drill holes for water inlet, vent outlet and wiring if it is intended to install the
heater with concealed electrical and plumbing connections.

Remove cover fastening screws and lift cover away from chassis.

Install plumbing and wiring, and prepare pipe ends for connection as shown in
step 3.

Screw heater chassis to wall using screws or bolts suited to the wall surface.
Screws/bolts must be able to support the following weights when filled.
