SIX MONTHLY / YEARLY MAINTENANCE
For all the machines
a)
Carefully clean the heating elements of any scaling.
This is of a great importance for the performance of
the boiler, and it is easy to do. Simply remove the
flange with the heating elements and carefully clean
them. During this operation it is important to
disconnect the tube that connects the pump to the
boiler, and clean the joint, where the water enters
into the boiler, of any deposits
obstructing it.
b)
Check the various gaskets and gate valves as
continuous heating and cooling can cause leaks.
Should there be leaks, remove the gaskets and
gate valves and replace with new to prevent further
leaks.
c)
Clean the water filter fitted to the feed electrovalve.
To do this, remove the sleeve, remove the filter
inside the electrovalve and clean the latter with
compressed air.
d)
Disconnect the copper pipes that connect the
gauge and the pressure gauge and clean them
internally to remove any scaling.
e)
Remove the probes ("POS. 58" see page 13-2) and
carefully clean it of any sediment or scaling using
an emery cloth. Assuring that the spindle/electrode
doesn't revolve in the sonde support body,
Most problems are caused due to lack of maintenance; undertake maintenance operations regularly, see "Maintenance".
Before proceeding with the problem resolution operations, read carefully the "Safety warnings".
Problem:
1.
The pump works and produces a
strange noise without stopping
2.
The boiler does not gain pressure. 2.
BREAKDOWNS ON THE BOILER AND ON THE ELECTRONIC LEVEL CONTROL
1.
The water feeding valve is open,
but the pump proceed to load.
2.
Water is sucked back during
steam generation at ironing start.
3.
Water is sucked back during
steaming,

otherwise tighten the superior nut.
f)
Check the condition of all the labels and plates on
the machine (warnings and instructions). If they are
in poor condition, replace them.
g)
Disassemble the safety valve and clean the joint,
on which is assembled, of any scaling. Also check
that the valve is not obstructed.
h)
Check the condition of all the external insulation
protecting
eventually replace them with new insulation.
For machines with tank:
a)
Clean carefully the little net of the two water filter
("POS .70" and "POS. 71" see page 10-11) on the
condensate recovery tank.
INSPECTION PROCEDURES
ANNUAL
Carry out a visual inspection inside the boiler, at least
once a year, to control the conditions of the inside walls
and the presence of possible scales and/or corrosions.
Carefully clean the inside of the keg containing the
probe, and all the inside walls of the boiler.

Letting the pump run without
water will damage it beyond
repair.

2.
With the machine in operation,
drain water from the boiler by
opening the boiler drain ball
valve slowly until the pump starts
re-loading water. Now close the
drain cock.
