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.
4.1.1Control 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 identification label. It is especially important that the supply voltage does not differ more than
•The connection to mains electricity must be carried out by a Qualified 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 Qualified 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 Qualified 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 Qualified 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.
