CHAPTER 7: USING THE EQUIPMENT
7.1 WARNINGS
The equipment must not be used with any of
its parts disassembled: before using the
equipment make sure that all its components
are properly in place.
To ensure that work is done in absolute safety
always make sure that you follow the described
procedures with caution.
7.2

SAFETY SYSTEMS

To ensure optimum working reliability, Zhermack
employs only top quality materials and components for
the manufacture of the equipment. The equipment is also
thoroughly tested before delivery. All materials are of only
the highest quality and are checked on arrival at our plant,
during storage and when they are used so as to guarantee
a product that is free from damage, deterioration and/
or malfunctions. In particular, the steam generators, in
addition to the safety fuse and safety valve, have:
1. On the VAP 8A.
Automatic pump shutdown if the pump overheats
because of high pressure or lack of water.
To reset the pump proceed as follows:
- turn the element switch to OFF (14);
- switch off the machine via the main switch (13) and
remove the plug from the power socket;
- let the pump cool down, operation will resume
automatically as soon as the temperature falls back
within the safe operating limits.
2. On the VAP 8 and VAP 8A.
Internal safety pressure switch, which shuts down the
machine if working pressure exceeds 8 bar; in this event
the overpressure warning light comes on. To reset the
machine proceed as follows:
- release pressure via the gun until it drops to 1 bar;
- turn the element switch to OFF (14);
- switch off the machine via the main switch;
- switch the machine back on.
• If the overpressure warning light comes on
repeatedly, switch off the steam generator via
the main switch and contact an Authorised
Service Centre.
• If the safety valve should open proceed as
follows:
- turn the element switch to OFF (14);
- release the pressure via the gun until it drops
to 1 bar;
- switch off the steam generator via the main
switch and contact an Authorised
Centre.

START-UP AND OPERATION

If you are using the kit (XR0020065 gun kit),
make sure the gasket at the end of the gun is
present. If there is no gasket, replace it with
the one in the kit, making sure the nozzles are
correctly inserted to avoid flow-back of water
and/or steam towards the user.
After setting up the equipment proceed as follows:
• On the VAP 8 - Fig. 15
Switch the element on via the relevant switch (14):
the on-switch LED comes on. The "water low" warning
light (4) and element ON indicator light (5) come on
simultaneously. After five seconds the "water low" warning
light goes out automatically while the element ON
indicator light (5) stays on until pressure reaches 8 bar. If,
after 5 seconds the "water low" warning light (4) remains
on, the boiler must be filled with water (see section 6.6.1).
Press the trigger button (10) on the gun and the steam
exits the gun nozzle. Adjust steam outflow as desired by
acting on the knob (9); rotate anticlockwise to increase
flow and clockwise to decrease. When the steam starts
flowing out of the gun the pressure in the boiler drops and
the element ON indicator light (5) comes back on.
• On the VAP 8A - Fig. 16
Switch on pump and element by acting on switch (14);
the LED on the switch comes on, the "water low" warning
light (4) comes on and the pump starts working. When
the water level in the boiler reaches the minimum level
the indicator light (4) goes out and, at the same time, the
element ON indicator light (5) comes on and stays on until
pressure reaches 8 bar. Select the work mode by acting
on switch (18). Press the trigger button (10) on the gun
and the water (or steam) will exit the gun nozzle. Adjust
steam outflow as desired by acting on the knob (9); rotate
anticlockwise to increase flow and clockwise to decrease.
Once steam starts flowing out of the gun the pressure in
the boiler drops and the element ON indicator light (5)
comes back on.
To deliver steam from the fixed nozzle, place the object
being processed under the nozzle (1) and press the fixed
nozzle button (6).
• When using the fixed nozzle, the operator
should touch the special metallic disk (7, Fig. A)
located on the side of the appliance, so as to
discharge any static electricity.
• The steam generator can, however, be used
before the "element ON" indicator light goes
out; in this case, though, the pressure displayed
on the gauge will be below 8 bar.
• If you are in possession of a VAP 8A note that
it is inadvisable to use the water function for
Service prolonged periods of time.
• Always empty the boiler if you do not expect
to use the steam generator for some time (see
section 8.3.1).
