WARNING:
This appliance must be earthed. This appliance
must be wired in accordance with these instructions. Any fault
arising from incorrect wiring cannot be put right under the terms
of the Saunier Duval guarantee.
All system components must be of an approved type.
Do not interrupt the mains supply with a time switch or
programmer.
Connection of the whole electrical system and any heating
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 3mm 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.
IMPORTANT:
If a replacement mains supply cable is required
it must be purchased. Part Number S1008600.
