The electrical mains supply needs to be
230V/50Hz.
Connections must be made using suitable
double-pole linked isolator switches which
are located within 2m of the appliance. The
supplies must only serve the appliance.
The minimum breaking capacity of the main
isolation switch and cable sizes/lengths at
230V shall follow the recommendations in the
table below.
The low current signal supply cable should be
1.0mm² flat twin and earth terminating in a
suitable isolator switch fused at 2 amps.
The location of the appliance will need to
provide a suitable route and termination point
for the discharge pipe from the CA Valve/PRV.
2.0 INSTALLATION
2.1 SITE REQUIREMENTS
The appliance is designed to be installed in an airing/cylinder cupboard and the
relevant minimum dimensions are provided in section 1.2 Technical Data.
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 fitted 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/floor.
Installation and maintenance access is needed to the front of the appliance and
the separate expansion vessel. See Technical Data section for further details.
The minimum dimensions contained in section 1.2 Technical Data 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 floor of the cupboard needs to be level and even and capable of supporting the
weight of the appliance when full. If the ElectraMate 2000 is located on a platform
above the floor this must provide continuous support to the whole back area and
be made of a material which will not deteriorate if exposed to moisture. Details of
the weight when full is provided in section 1.2 Technical Data.
The appliance is designed to operate as quietly as practicable. However, some noise
(from pumps etc) is inevitable in any heating system. This will be most noticeable
in cupboards formed on bulkheads, or at the mid span of a suspended floor. In these
cases the situation can be improved by placing the appliance on a suitable sound
deadening material (i.e. carpet underlay or similar).
Cupboard temperatures will normally be 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.
A suitable location will be needed for the separate expansion vessel. This will often
be at high level in the cupboard housing the ElectraMate 2000 but can be at a remote
position if required. The dimensions and clearances are provided in section 1.2
Technical Data. The location will need to provide a suitable route for the expansion
pipe from the vessel to the appliance.
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.
All Electrical work must comply with the IEE Requirements for Electrical Installations (BS 7671). It is the responsiblity of
the competent Electrical Installer to use the details below in conjunction with the latest British Standards
