WARNING
• Make sure ice has not formed inside the pump, hoses and tank if the appliance is used in
very low temperatures.
• The routine maintenance checks must be carried out, particularly those concerning the
oil.
4.1.1 Control and connection to mains electricity
CAUTION
• A Skilled Technician must check that the electrical supply complies with the data indicated
on the electric motor’s identication label. It is especially important that the supply voltage
does not differ more than +-5% from that indicated on the label.
• The connection to mains electricity must be carried out by a Qualied Electrician according
to IEC 364 regulations or the equivalent standard in the country where the appliance is to
be used. It is especially important that the current outlet where the appliance is connected
is provided with an earth conductor, a suitable fuse, and it must be protected by a magneto-
thermal differential circuit breaker, whose sensitivity is not in excess of 30 mA. It must be
possible to insulate the appliance from the mains electricity with a universal switch with 3
mm minimum opening between its contacts.
• If the appliance is not to be connected permanently to the electric supply and the power
cable is not provided with a plug, contact a Qualied Electrician for the installation of a
plug according to the current regulations in the country where the appliance is to be used.
• If the appliance is to be connected permanently to the electric supply, it must be installed
by a Qualied Electrician according to IEC 364 regulations or the equivalent standard in
the country where the appliance is to be used. It is especially important that regulations
are followed concerning its connection to earth, protection by a suitable fuse and magneto-
thermal differential circuit breaker, whose sensitivity is not in excess of 30 mA, and the
insulation of the appliance from the mains electricity with a universal switch with 3 mm
minimum opening between its contacts.
Note: to facilitate the reader, these operating and maintenance instructions always assume
that the appliance is connected to the electrical supply with a plug.
If the appliance is connected permanently to the electrical supply, it is presumed that:
- when the universal circuit breaker is in the off position (‘0’ position) it is equivalent to the
plug being disconnected from the current outlet.
- when the universal circuit breaker is in the on position (‘1’ position) it is equivalent to the
plug being inserted in the current outlet.
• If the power supply cable is too short, an extension cord can be used provided it is no longer
than 50 m /164 ft, the section of the wires is at least 1.5mm² and the plug and the socket are
waterproof. Contact a Qualied Electrician to ensure all these requirements are met.
• The use of unsuitable extension cords can be dangerous.
• Do not use adaptors between the electric plug and the current outlet.
