2.0 INSTALLATION
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
above the F & E cistern. See section 1.2 Technical Data 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. 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).
The cylinder is very well insulated and no ventilation is normally required to the
cupboard.
A suitable location will be needed for the separate feed and expansion cistern (OV
model) or expansion vessel (SS model). This will often be on top of the appliance
itself or at high level in the cupboard housing the Accolade 2000. The dimensions
and clearances are provided in section 1.2 Technical Data. The location will need
to provide a suitable route for the cold feed/expansion pipe and safety/open vent
pipe for the appliance (OV model) or the connecting pipe to the system expansion
vessel (SS model). A suitable route and discharge position for the warning/overflow
pipe and the ballvalve supply from the mains cold water system will also be required with
the OV model.
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/1Ph
Connection must be made using a double-pole linked isolator with a contact
separation of 3mm in both poles which is located within 1m of the appliance. The
supply must only serve the appliance.
The supply to all the indirect appliances shall be fused at 16 amp.
The on and off peak supplied to all the direct models shall each be fused at 16 amp.
Normally these will be provided from a suitable off peak hot water controller located
adjacent to the appliance.
