Current Device (RCD) with rated earth leakage operation not excee-
ding 30mA must be fitted upstream on the supply line. The circuit
breaker must have a contact opening distance of at least 3 mm.
Be careful to connect the heater to a supply line protected by 16 A
fuses not quick-acting type.
The heaters should always be installed horizontally only using the
•
mounting brackets provided. This ensures correct positioning and
adequate clearance.
A minimum air gap of 40 cm should always be allowed between
•
the top of the heater and a ceiling or roof. The appliance should be
60 cm far from the walls (fig.1).
A safety distance of not less than 100 cm should always be left in
•
front of the IRIS heaters or too near.
This unit should be mounted at a minimum of 180 cm above ground
•
level (fig.1). If installed in a toilet, the height should be 225 cm in
zone 1 and zone 2; in zone 3 the minimum above ground level is
180 cm, according with the rules of each Country.
Be sure that the heater is not facing the ceiling or inflammable
•
substances.
The appliance must not be located neither directly below, nor in
•
front of a socket-outlet.
The heater must be installed so as to prevent that the switches can
•
be touched from those who are in the shower.
Ensure that there is no possibility of inflammable material, com-
•
bustible material or curtains coming into contact with the heater,
or lie near the heater.
Heaters should not be installed in areas where hazardous vapours
•
may be present. Defined in BS5345.
The heaters are fitted with safety guards. These are intended only
•
to stop large objects from hitting the emitters. On no account
should the heater be operated with the guard removed.
For consumer use the heaters are fitted with high temperaure sili-
•
cone rubber flexible cable (H05 RN-F) conforming to BS 6500.
The models for professional use, that are marked with a "P" in the
•
code, do not have the power cord and the switch. For professional
installation, cabling of the same specification should be selected.
