TURNING OFF
To turn the water cleaner off, you must:
• if the burner is still on:
• rotate anticlock wise the thermostat knob (3) up to the end,
• let the machine operate for at least 2 minutes to cool down and
rinse the hydraulic circuit,
• press the burner switch (2) to "0" position
• press the red key "0" of the magneto-thermal switch (1).
HINTS FOR FREEZING
During winter season the water cleaner must not be kept in the
cold except for normal operation; after use, turn off the burner but ,
before stopping completely the machine, close the water mains cock
and let the water cleaner operate until the water in the hydraulic circuit
is expelled.
In case of long breaks at low temperatures it's advisable to use an
antifreeze product. Empty the hydraulic circuit thens witch on the water
cleaner letting it suck the antifreeze through the water suction pipe and
through the detergent suction pipe to fill up completely the hydraulic
circuit.
WATER SANDBLASTING DEVICE (OPTIONAL FOR EVERY MO-
DEL)
Connecting the water sandblasting device to the water cleaner
could result useful to wash and clean rusty or covered with hard scales
or painting surfaces.
It's easy to connect (see picture below): just replace the washing
lance with the sandblasting one (1) and introduce the sand suction pipe
(2) into the container (3), using dry, quality sand suitable for this use
(quartz sand or siliceous sand).
When the water cleaner is started, the sand (a) is sucked, mixed to
water (b) and addressed to wards the surface to be treated , freeing it
from scales.
