 The Building Standards Regulations, 1981
For others countries the follow appropriate local rules should be observed:
 Building regulations and fire prevention provisions
 Current safety regulations
 Electrical supply company provisions
 Current electrical regulations
 Fire authority provisions.
Preliminary steps
Remove the appliance from the packaging, ensure that it is intact and, if in doubt, do not use it but
contact professionally qualified personnel. The packaging materials are compliant with environmental
safety regulations. They can be stored without risk, or else should be disposed of in accordance with
current national regulations, particularly those regarding the nylon bag and the polystyrene.
After verifying that the appliance is in good conditions, the protective film may be removed. Clean
the external parts of the appliance carefully with warm water and detergent, using a cloth to remove
all remaining residues and then dry it with a soft cloth. If there are still traces of glue, these can be
removed using a suitable solvent (e.g. acetone). Under no circumstances should abrasive substances
be used. After the installation the appliance should be levelled by lowering or raising the adjustable
legs.
Electric connection
Before connecting the appliance, it is necessary to check that the voltage of the power supply
available corresponds to the voltage the appliance has been set for. In the event that they do not
correspond, it is necessary to modify the connection as shown in the electric diagram, if voltage
change is provided for. The terminal blocks are situated behind the instrument board and they can
be removed unscrewing the 2 screws that fix the support. Before connecting the cable to the
terminal blocks, it is necessary to let it pass through the cable gland. If the supply cord is
damaged, it must be replaced by the service agent or similarly qualified persons in order to
avoid a hazard.
Furthermore, the efficiency of the earth connection must be checked, and also that the earth
conductor on the connecting side is longer than the other conductors, and that the connecting cable
has a wire bunch adequate for the power absorbed by the appliance and is at least type H07 RN-F.
As in international provisions, before installing the appliance a unipolar device must be
installed with a contacts opening of at least 3mm which must not interrupt the YELLOW-
GREEN earth wire. The device must be installed near the appliance, it must be approved and have
adequate capacity for the absorption of the appliance (see technical features).
The appliance must be connected to the EQUIPOTENTIAL system. The connector is situated near
the end of the electric cable and is identified by a label with the symbol shown on figure 6 (page. 3).
When using a safety switch for fault currents, the following should be observed:
- According to current legislation, this kind of appliances can have a leakage current of 1mA
per kW of rated power input with no maximum. It should also be noted that all fault current
protection switches available on the market have a current tolerance of less than 50%;
therefore, a suitable switch should be chosen.
- Connect only one single appliance to each switch.
In some cases, after long periods of inactivity or with a new installation, it is possible that the
appliance trips the safety switch when it is turned on. The reason for this is usually moisture in the
insulation. The problem can be solved by a short pre-heating that bypasses the safety thermostat.
