Frank FH 711 TS Operating Instructions Manual page 28

5.5.2 Electrical supply
The unit comes with a supply cable with mains plug.
Insert plug into a properly earthed socket. The electrical supply with socket must
conform to the latest issue of the applicable ICE standards and installed by a quali-
fied electrician. The socket must be secured with 16 A.
We recommend to equip the electrical supply of the unit with a fault current monitor, breaking
the circuit when the leakage current to the ground exceeds 30 mA for a period of 30 ms.
When using an extension cable, this cable must conform to HO7RN-F quality and
have a grounded lead wire properly connected to the plug-in connections. The
lead wires of the extension cable must have a minimum cross section of 2,5 mm².
The plug-in connections must be splash-proof and must not be placed on
wet ground.
ATTENTION:
Too long extension cables will cause a voltage drop and thus operating troubles and start-up
problems.
5.5.3 High-pressure hoses and spray lance systems
Tightly screw-fasten the high-pressure hose to the high-pressure supply of the machine and
the spray gun so that it is pressure sealed. Tightly fasten the screw fitting of the spray lance
in a way that is sealed against pressure.
The high-pressure hose and spray lance, which are both part of the machine eqipment, are
made of high-quality material, adapted to the operating conditions of the machine, and have
been marked in accordance with the regulations.
In case spare parts are needed, only those parts may be used which have been approved
and marked by the manufacturer. High-pressure hose and spray lance must be connected
in a way that they are sealed against the pressure. The high-pressure hose must not be run
over, excessively tugged at or twisted.
5.5.4 Water supply
The machine must be connected to the water supply using a 1/2" hose with an inner dia. of
13 mm suitable for the supply pressure. A minimum supply corresponding tothe maximum
flow rate of the applicable machine type must be ensured. Flow pressure must be at least 2
bar. Static pressure must not exceed 10 bar.
The water inlet tank of the machine must be filled by opening the tap.
