CARE AND MAINTENANCE.
ATTENTION
• ALWAYS DISCONNECT THE APPLIANCE FROM
ELECTRIC POWER SUPPLY AND ENSURE THAT
THE SYSTEM IS NOT PRESSURISED.
• You can arrange a regular safety inspection or a mainte-
nance contract with your dealer.
• The first and most important oil change must be made
after the first 20 working hours.
8.1 Weekly
• Check the oil level.
If the oil is milky (water in the oil) contact customer service
immediately.
• Clean the water inlet filter.
8.2 Monthly
• Clean the filter on the detergent suction hose.
• OPERATION TO BE CARRIED OUT BY THE MAIN-
TENANCE SERVICE ONLY Clean and adjust the electro-
des and if necessary replace them, following the attached
mounting diagram. (See chap. 15).
8.3 Annually or after 500 working hours or when re-
quired
• Change the oil.
• Unscrew the oil drain plug and dispose of the oil through
an authorized collecting point, (protection of environ-
ment).
When the oil has completely drained, screw the oil drain
plug back and slowly pour in oil up to the level correspon-
ding to the indicator located on the crankcase itself. (Ensure
the air bubbles are eliminated).
• See technical data chap. 1 for oil type and quantities.
8.4 Cleaning soot from heating coil
• If the heating coil becomes sooted within a short time, you
should have the burner setting checked by the authorized
customer service. If the burner setting is incorrect, the fuel
consumption will be increased, polluting the environment
unnecessarily
8.5 Decalcifying the heating coil
• If the appliance continually switches on and off at max.
operating pressure, or if the pressure on the pressure gauge
increases to more than 10 bar without the high pressure
hose being connected at the maximum water flow, internal
deposits/calcification are the probable cause.
• We recommend you to contact the authorized customer
service to carry out decalcification and check the dosage
of descale liquid.
8.6 Cleaning the fuel tank
• Dispose of the remaining fuel in proper tanks (protection
of environment).
• Rinse the tank carefully. If you rinse with water, let the
tank dry completely.
• Replace (if necessary) the fuel filter.
8.7 High pressure hoses
• Carefully check H.P. hoses.
• All H.P. hoses must comply with the safety rules and must
be marked with their working pressure and the name of
manufacturer.
• H.P. hoses must not be bent, twisted, crushed or damaged
in any way.
• Damaged H.P. hoses are dangerous and must be replaced
immediately.
• H.P. hoses with a lower pressure capacity or inexpertly
repaired might be dangerous.
You should only use H.P. hoses marked and tested. (original
H.P. hoses meet all the safety requirements).
8.8 Connecting cable
• OPERATION TO BE CARRIED OUT BY THE MAIN-
TENANCE SERVICE ONLY The connecting cable must
not be damaged (danger of electric shock). A damaged
connecting cable must be replaced immediately by autho-
rized customer service/electrical engineer.
8.9 Anti-freezing protection
• If water has not been completely drained, frost damages
the appliance. During winter the appliance should be kept
in a warm room, otherwise it is recommended to empty the
appliance or rinse it thoroughly with anti-freeze.
• Draining the appliance :
- Unscrew the water intake hose and high pressure hose
from the appliance.
- Unscrew the supply line from the base of the boiler and
allow the heating coil to drain: Allow the appliance to run
for a max. of 1 minute until the pump and the lines have
drained.
• Anti-freeze
During extended time of non operation, it is recommended
to pump an anti-freeze through the appliance. This also
protects the appliance from corrosion to a certain degree.
8.10 Use after a long storage period
• If the unit has been stored for a long time, there is the
possibility of calcium deposits build-up. This could make
instant starting difficult and harmful. In this case, to avoid
the consequences of electrical overcharging, before you
plug the unit, we suggest to turn the motor shaft with the
key supplied.
• By performing the above, you will also avoid damaging
the unit, were it frozen or blocked due to scaling.
