Introduction; Important Notes; Basic Operation Of The Electromax - Heatrae Sadia ELECTROMAX Installation & Servicing Instructions Manual

1.0 Introduction

1.1 Important Notes

The Electromax must be installed in
accordance with the manufacturer's
instructions and all relevant regulations
in force at the time of installation.
This appliance is not intended for use
by persons (including children) with
reduced physical, sensory or mental
capabilities, or lack of knowledge
and experience, unless they have
been given supervision or instruction
concerning the use of the appliance by
a person responsible for their safety.
The Electromax Domestic Hot Water
Cylinder is of the UNVENTED type.
Its installation is subject to Building
Regulation G3 (England and Wales),
Technical Standard P3 (Scotland) or
Building Regulation P5 (Northern Ireland).
Installation must be carried out by a
competent person.
The Electromax should be installed and
maintained by a competent person. Please
read and understand these instructions
before installing the Electromax. Following
installation and commissioning the
operation of the Electromax, the central
heating system and associated controls
should be explained to the customer and
these instructions left with them for future
reference.
The Electromax electric heating boiler must
be installed into a sealed (pressurized)
primary system. Following installation of
the primary system the system should be
flushed in accordance with BS 7593 and
an inhibitor added.
The Electromax Domestic Hot Water
cylinder is directly heated by means of
electric immersion heaters. The electric
central heating boiler although housed
in the same casing operates completely
independently to the cylinder. It is strongly
recommended that the water heating is
done by means of an Off-Peak electrical
supply.
The use of an Off-Peak tariff that provides
at least three off peak electricity periods,
such as Economy 10, is recommended.
Where possible the central heating
"on" periods should be programmed
to coincide with the off peak electricity
periods available during the day. This
will ensure maximum economy of the
system. Refer to Table 2, Page 19 "Tariff
Guide" for information on the off peak
periods available from various electricity
providers.
The Electromax does not contain any
substances harmful to health; it does not
contain any asbestos. Small quantities
of adhesives and sealants used in the
manufacture of the product are cured and
present no known hazards.

1.2 Basic operation of the Electromax

The Electromax is an integrated electric flow
boiler and direct electrically heated unvented
domestic water heating cylinder.
The domestic hot water is preferentially
heated by an Off Peak electricity supply via an
immersion heater that is specially designed to
heat virtually the complete cylinder capacity.
A "Boost" immersion heater is also provided
to allow a smaller quantity of water to be
heated should the stored hot water be fully
used during the day. The cylinder is factory
insulated with a low heat loss expanded
polyurethane foam.
