ELECTRICAL CONNECTION
Warning. This boiler must be earthed
All system components must be of an approved type.
Connection of the whole electrical system and any heat-
ing system controls to the electrical supply must be
through a common isolator.
Isolation should preferably be by a double pole switched
fused spur box having a minimum contact separation
of 3 mm on each pole. The fused spur box should be
readily accessible and preferably adjacent to the boiler.
It should be identified as to its use.
A fused three pin plug and shuttered socket outlet may
be used instead of a fused spur box provided that:
a)
They are not used in a room containing a fixed bath
or shower.
b)
Both the plug and socket comply with the current
issue of BS1363.
The mains electrical supply must be maintained at all
times in order to provide domestic hot water.
Do not interrupt the mains supply with a time switch
or programmer.
WARNING: ON NO ACCOUNT MUST ANY EXTER-
NAL VOLTAGE BE APPLIED TO ANY OF THE TER-
MINALS ON THE HEATING CONTROLS CONNEC-
TION PLUG.
Warning
: This appliance must be wired in accordance
with these instructions. Any fault arising from incor-
rect wiring cannot be put right under the terms of the
Saunier Duval
guarantee.
External controls
The ISOFAST boiler is designed to operate at maximum
efficiency at all times, but will be most efficient and eco-
nomical when connected to a room thermostat.
A suitable room thermostat is available as an accessory,
Saunier Duval part number 40011
. Please contact your
supplier.
The boiler will work for heating without a room ther-
mostat being connected provided that the wire link fit-
ted between the two terminals of the connector (E) is
left in place, see diagram 17.
Alternatively, a 230V room thermostat can be used but
do not make any connection to the compensating resis-
tor, see diagram 17.
ON NO ACCOUNT
must any electrical voltage be ap-
plied to any of the terminals of the external controls
plug.
Note: For further information, see the building
regulations 1991 - Conservation of Fuel and Power
- 1995 edition - appendix G, Table 4b.
