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 identiﬁcation 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 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.

a) Unroll the delivery hose (1) completely.

b) Check that the adjuster (24) for the lance (13) is turned completely towards “S” so that

the lever (26) can be put in the “OFF” position. Put the tap lever (41), if any, in the “OFF”

position.

c) Check that there is no pressure in the delivery hose as follows:

turn the knob (29) on the adjustment valve anti-clockwise as far as it will go; this is only

necessary for MC16 as it does not have lever (30).

operate lever (30) and put it into the “BY-PASS” position.

d) Start up the appliance so it can prime. If the appliance is ﬁtted with an electric motor, operate

both the universal circuit breaker on the socket that the appliance is connected to, and the

switch on the electric motor, if any, by putting them both in position “1” (please remember

to take into account the recommendations regarding three-phase motors in the “Controls

and connection to mains electricity” section). For appliances ﬁtted with a combustion

engine, follow the instructions for the start up of the same in its operating and maintenance

instructions.

e) Bring the appliance up to pressure as follows:

operate lever (30) putting it in position “PRESS”.

turn the knob (29) until the required pressure is reached (turn clockwise to increase

g) Operate the lever (26) on the lance (13) to achieve the required spraying angle (from an

empty cone to a needle-point jet). The adjuster (24) can be used to ﬁx the preferred position

for spraying. We recommend this is done while spraying with the lance into the tank to avoid

wasting chemicals.

h) The ﬂow rate of the sprayed liquid depends on the operating pressure, the nozzle (27) used

(the 1.5 mm Ø nozzle is supplied as standard with the appliance) and the adjustment of the

spray angle. Refer to the table below for information on which nozzle to use for a job (note

that the maximum ﬂow is indicated, i.e. corresponding to a needle-point spray angle).
