3 Instructions for use
3.1 Introduction
Your Vaillant uniSTOR unvented hot water cylinder and
Vaillant boiler, together provide you with a modern,
efficient, high performance heating and hot water
system.
Because your uniSTOR hot water cylinder is supplied
with water directly from the mains, you get the benefit
of mains pressure hot water at your hot taps, without
the need for storage tanks in the loft and without a hot
water pump. The uniSTOR is made from high quality
stainless steel within an easy clean casing. The cylinder
is fully insulated using environmental friendly EPS
insulation to help keep your hot water running costs at a
minimum, and protect the environment!
Your uniSTOR cylinder is tailor made to accompany a
Vaillant boiler as well as any other UK standard boiler.
All Vaillant boilers are equipped with 'built-in' energy
saving technology, such as burner modulation, anti
cycling control and high efficiency heat exchangers.
Please read these instructions carefully to ensure that
you get the very best out of your Vaillant heating and
hot water system.
3.2 Liability
Warning!
We can accept no liability whatsoever for damage or
injury resulting from failure to observe these
instructions.
Specified use
Vaillant uniSTOR unvented cylinders are made to fulfil
the latest technical specification and official safety
regulations. These cylinders are designed for use with
UK standard boilers for use in hot water supply systems.
The term 'specified use' also covers observance of the
operating and installation instructions, along with
adherence to the servicing schedules. At the rear of this
manual you will find a Benchmark Cylinder Commissioning
Checklist which should be completed by the installer
and/or commissioning engineer and handed to the user.
All CORGI registered installers carry a CORGI ID card and
have a registration number. Both should be recorded in
your Cylinder Commissioning Checklist. You can check
your installer by calling CORGI direct on 01256 372300.
Note!
Your uniSTOR unvented hot water cylinder must
be installed by a competent person in
accordance with current Building Regulations.
Do not remove or adjust any component part of
this cylinder. In the unlikely event that your
uniSTOR develops a fault, such as a flow of hot
water from the discharge pipe, switch the boiler
and immersion heater off and contact Vaillant
Ltd or your installer.
Note!
If the uniSTOR is installed in a cupboard used
for airing purposes please ensure that clothing
or other articles are not placed on the cylinder
or its associated controls.
Note!
Access should always be maintained to allow
operation of the domestic hot water thermostat
control.
3.3 How to use your uniSTOR hot water cylinder
Your boiler and uniSTOR unvented hot water cylinder
will provide both central heating and mains pressure hot
water.
Check that the boiler is operational as detailed in the
instructions for use supplied with the boiler.
The domestic hot water thermostat on the uniSTOR can
be set from 20 °C to 65 °C. The desired temprature will
be set by the installer while commissioning the uniSTOR
(normally a setting of 60 °C is adequate).
Note!
In hard water areas the DHW temperature
selected should not exceed this setting to avoid
possible scale build-up.
If a programmer has been fitted to control the central
heating and hot water, check that this is set to the
desired on and off periods.
The boiler will then operate automatically to heat the
cylinder contents at the desired times to the
temperature selected. When domestic hot water is used,
the boiler will operate to re-heat the cylinder as
required.
