INTRODUCTION

Your new water boiler is designed to give years of trouble free service provided
that the instructions contained in this manual are followed carefully.

Your new boiler is energy efficient, simple to operate and easy to service.
It is recommended that the installation is carried out by a properly qualified fitter.

CHECK LIST

Before starting installation, check that you have the following parts:

1. Boiler Unit

2. Case

3. Mounting Template

4. Fitting Kit

5. Tap Kit (WB5E Only)

INSTALLATION

POSITIONING THE UNIT

The heater should be positioned in a convenient place on a wall that is capable
of supporting it safely. Use the mounting template and fitting kit provided.

Position the boiler so that the tap is about 400mm above a draining board.
Leave sufficient space around the unit to enable access for servicing, paying
particular attention to the position of the top centre fixing screw that holds the
cover in place.

Screw in the top two screws leaving about 6mm protruding and hang the
machine using the keyhole slots provided. Once the machine is positioned,
tighten the top screws and insert the bottom screw.

ELECTRICAL CONNECTION ALL MACHINES

Supply – 220/240V 50Hz – 3kW. The circuit should be protected by its own
13amp double pole connection unit with flex outlet to BS5733, alternatively the
circuit should have means of disconnection incorporated in fixed wiring, having
a contact separation of at least 3mm in all poles. Minimum cable size is 1.5mm2.
The use of an ELCB is recommended.

Electrical installation should conform to current I.E.E. wiring regulations.
When using fixed wiring, the bare section of earth wire must be sleeved to

within 8mm of the end.
Only a qualified electrician should carry out this work.

WATER CONNECTION

NOTE: Although it will not harm the boiler, it should not be operated with
the water supply turned off.

The water supply must have a pressure not exceeding 7 Bar (700kpa) and no
lower than 1 Bar (200kpa). If the mains water pressure is below1 Bar a fault

situation could arise as described in section; “Temperature Control and
Safety cut-outs”.In addition the water inlet valve may not seat properly
and can cause overflowing

If your water pressure exceeds 7 Bar, a suitable pressure reduction valve will
need to be fitted to the water supply to bring it to a level that the machine can
cope with. Failure to do this could result in the boiler overfilling .

The manufacturers cannot be held responsible for any machine malfunction if
the water pressure exceeds that stated. If in doubt, consult your water supply
company.

The boiler has a type B air gap in compliance with water bylaws and has both
WRAS and KIWA approval.

Please note that washing machine hoses are not suitable for drinking
water and will cause a very bad taste to the water.

A 15mm stop valve should be fitted between the water supply and the boiler so
that the machine can be isolated. Water purification filters are available to
ensure fresh tasting water. Please contact the service department for details on
01704 502911. In hard water areas scale can cause problems. Fitting a scale
reducer will help minimise scale.

We regret that the manufacturers cannot be held responsible for scale problems
even if a scale reducer has been installed.
