INSTALLATION
The appliance is designed to be installed in an airing/cylinder cupboard and the
relevant minimum dimensions are provided in the Technical Data section of this
manual.
Because of the ease of installation we recommend that the cupboard construction is
completed and painted before installation of the appliance. The cupboard door can
be fi tted after installation.
If the unit needs to be stored prior to installation it should be stored upright in a dry
environment and on a level base/fl oor.
Installation and maintenance access is needed to the front of the appliance and above
the Top up cistern. See the Technical Data section of this manual for further details.
The minimum dimensions contained in the Technical Data section of this manual
allow for the passage/connection of pipes to the appliance from any direction as long
as the appliance is installed on the installation base provided. If the installation base
is not used extra space may be needed to allow connection to the pipework and the
whole of the base area should be continuously supported on a material which will
not easily deteriorate if exposed to moisture.
The fl oor of the cupboard needs to be level and even and capable of supporting the
weight of the appliance when full. Details of the weight when full is provided in the
Technical Data section of this manual.
The appliance is designed to operate as quietly as practicable. However, some
noise (from pumps etc) is inevitable when hot water is being used. This will be most
noticeable if the cupboards are located adjacent to bedrooms, on bulkheads, or at
the mid span of a suspended fl oor. Some noise may also be experienced from the
immersion heaters as the store approaches its design temperature.
Cupboard temperatures will normally be slightly higher than in a conventional
system and the design of the cupboard and door will need to take this into account.
No ventilation is normally required to the cupboard.
The separate Top up cistern will need to be located on top of the appliance or at high
level in the cupboard housing the PulsaCoil A-Class. The dimensions and clearances
are provided in the Technical Data section of this manual. The location will need to
provide a suitable route for the cold feed expansion pipe as well as the open safety
vent pipe. The location will also need to provide a suitable route and discharge position
for the warning/overfl ow pipe and the ballvalve supply from the mains cold water
system (if provided) if these have been ordered as an optional extra.
Note: The standard appliance is supplied with a cistern without a ballvalve/
overfl ow for fi lling manually.
An electrical supply must be available which is correctly earthed, polarized and in
accordance with the latest edition of the IEE requirements for electrical Installations
BS 7671.
The electrical mains supply needs to be 230V/50Hz.
The sizes/types of electrical supplies must be as detailed in System Details section
of this manual. A means for disconnection from the supply mains having a contact
separation in all poles that provides full disconnection under over voltage category
III conditions must be incorporated in the fi xed wiring in accordance with the wiring
rules. This shall be located within 1m of the appliance and only serve the appliance.
The hot and cold water ‘fi rst fi x’ pipework should be terminated 50mm above the
fi nished fl oor level in accordance with the dimensions provided in the Technical Data
section of this manual.
