Maintenance and repair works may only be done by qualified personnel. Set main
and emergency switch to „0“ and protect against switching on. Keep off hot parts
– danger of burning. Maintenance and repair works may only be carried out by
qualified staff.
11.1 High pressure pump
Change the pumplubrication oil at intervals of approx. 200 operating hours, but at the
latest, after 3 months of operation. For lubrication use branded oils of SAE 90 quality only.
When changing the oil, remove the draining screw, drain the oil and dispose it properly.
Then put the oil draining screw back into place and refill new oil through the funnel until the
upper mark on the dipstick is reached. Between oil changes check the oil level regulary;
the oil level.
11.2 Deliming
If no soft or softened water is used, lime deposits will settle down in the heating coil.
Depending on the local water hardness, the heating coil must be delimed in regular
intervals to protect the unit from damages. Do not wait until the pressure is too high and
the safety valve responds or the protective motor switch cuts off the machine.
Deliming is carried out as folows.
Set motor switch to position „0“. Loosen elbow joint of the suction hose on the water inlet
tank and connect to deliming hose (which is a ½“ hose featuring a filter basket at one and
straight hose sleeve with ¾“ external thread at the other end) and direct out-side.
Turn the knob of the dosing valve to position „0“. Fully close the thermostat hand-wheel.
Fill 16 litres of hot water into a tank and add 2 litres of deliming compound SP.
Caution! The deliming agent is corrosive. Wear safety clothing.
In case of skin contact, rinse with water immediately.
Insert deliming hose into the tank, unscrew spray nozzle from the spray lance and place
lance into the tank. The deliming hose filter must always be situated below the liquid level
within the tank. Turn on the machine. The deliming process is completed when the liquid
has stopped foaming. Turn off the machine.
Empty tank, properly dispose of the deliming liquid. Fill 16 litres clear, cold water into the
tank and add 0,5 litres alcaline cleaning agent. Reinsert deliming hose and spray lance into
the tank.
Turn on the machine and flush heating coil using the alcaline solution for 5 minutes. Turn
off the machine, set motor switch to position „0“. Reconnect suction hose to the water inlet
tank, clean and reassemble spray nozzle. Mount and lock hood.
