explosions or fire: the equipment is not
prepared and/or designed to operate in
environments with explosive atmosphere or
with the risk of fire.
The working area lighting plant is an
important factor for the safety of persons
and the quality of work. In Italy this subject
is governed by a Ministerial Decree that
clearly determines the average level of
prescribed lighting. In other countries the
regulations in force are valid regarding
accident-prevention and hygiene in the
workplace.
6.3 SPACE NECESSARY FOR USE
The choice of the place and space required for
installation is an important factor for the quality
of work and safety and for correct maintenance
activities. This area must not only be spacious
enough to allow for optimum equipment operation
- also during cleaning and maintenance phases -
but must also be well lit, aired, not dusty and not
exposed to direct sunlight. Note also that the unit
must be positioned so the connection plug can be
handled/manipulated with ease.
6.3.1 WORKTOP
Fig. E - BENCH VERSION
The equipment has been designed for operation
on a rigid worktop parallel to the floor. Suitable
worktops include service furniture (where the
operator is standing) or modelling tables (where
work is done sitting down). All worktops must be
checked for stability.
Fig. F - WALL-MOUNTED VERSION
The equipment is also designed to be wall-mounted.
Before installation:
- make sure that there are no power sockets
or other objects that may be damaged by
accidental contact with steam/water located
underneath the appliance;
- make sure the holes are aligned
horizontally.
Once drilling is over, introduce the plugs in the
holes and then screw in the screws but not all the
way: let them protrude from the wall by 8-10 mm.
Check that the machine is stable before using it.
The right plugs for installation must be
chosen based on the weight of the appliance,
shown in section 4.2.2, and the type of wall
it is installed on.
Install the AD 8 water softener (where applicable)
in a place where ambient temperature is higher
than 0°C so as to stop the water in it freezing;
the installation site should also protect the
softener against accidental knocks and be perfectly
horizontal.

To prevent temperature imbalance, do not
use cold water when filling a boiler that is
still hot.
Failure to comply with any of the above-
stated equipment installation regulations
can lead to equipment malfunctioning and
render the warranty null and void.
6.6 FIRST-TIME USE VAP 8A
To prevent the formation of scale that may
in the long term affect correct operation or
even damage the VAP 8A steam generator,
connect the appliance to the mains water
supply via the AD 8 water softener.
Fig. 5: Place the steam generator on the work
bench and the softener on the floor, making sure
both are level (see section 6.3.1).
Before connecting up the hoses, remove any
rubber plugs inserted in the inlet/outlet
connectors on the AD 8 water softener.
Fig. 6: Connect up the water softener to the mains
water supply by attaching the hoses (23-22) to
the inlet tap (24) and water outlet tap (21) on the
softener itself. Then tighten the hose clips.
Connection to the water softener must only
be effected by qualified, authorised
personnel.
Fig. 7: Connect the water outlet hose (26) on the
softener directly to an open siphon (this must be
below the softener).
Fig. 8: To ensure that the resin in the exchanger
gives the required performance rinse the softener
by turning the knob (25) to position number
“4” (backflow position: see fig. B) for at least 10
minutes until the water outflow is perfectly clear.
When doing this direct the water into the open
siphon (see fig. 7).

Failure to comply with any of the above-
stated equipment installation regulations
can lead to equipment malfunctioning and
render the warranty null and void.
6.6.1 REGENERATING THE AD 8 WATER SOFTENER
- Fig. B
Regeneration frequency depends on how
often the AD 8 softener is used and the
degree of purity of the water. The installer
will be able to provide information
regarding the hardness of the water at the
installation site.
To regenerate the AD 8 water softener proceed
as follows:
• turn the water softener knob (25) to position 2.
Loosen the lid knob (27) and wait for the pressure
to be released.
• Remove the lid by unscrewing the knob (27), then
introduce the salt.
• Clean off any salt or resin that may have deposited
on the lid seal, replace the lid and screw it
back in place properly.
• Turn the knob (25) to position 3, and let the salt
water drain
from the hose (26) until it becomes fresh (this
takes about 40 minutes).
• Turn the knob (25) to position 4, wait about 30
seconds, then bring the knob (30) to position 1.
In the intervening 30 seconds the unit will not be
supplied with softened water.
• When regeneration is being carried out
the steam generator connected to the
softener is still supplied with water, but
the latter is not softened.
• To maintain AD 8 water softener
performance use the chart enclosed with
this manual to record regeneration data.
Use only NaCl (common cooking salt) to
regenerate the softener. Do not use acid or
basic substances, solvents or chemical
products.
6.7 DECLARED USE
The VAP 8 and VAP 8A steam generators have been
designed to generate steam or hot water to clean
semi-finished odontotechny products.
The AD 8 water softener has been designed
to soften the mains drinking water to ensure
long-lasting performance of the VAP 8A steam
generator.
6.8 NON-DECLARED/PROHIBITED USE
Using the equipment for any purpose not
considered in paragraph regarding
“Declared use” shall be considered improper
and thus forbidden. The improper use of the
equipment renders the warranty null and
void and Zhermack Spa declines all liability
for any damage to objects and injury to
operators or third parties.
The main reasons for which the warranty is rendered
null and void are given in paragraph 2.2 and in the
“Warranty Certificate” attached to this Manual.
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
S.p.A. 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.

EN
32 vap 8 - vap 8A - AD8
The reference figures can be found on pages 3, 4, 5, 6 of this manual.
• 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
Service Centre.
7.3 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 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).
7.4 RESIDUAL RISKS
Residual risks are:
• a danger that cannot be totally eliminated through
design and the application of safety devices;
• a potential danger that cannot be highlighted.
The steam generator produces steam or hot water
and therefore works at temperatures of over
100°C; the residual risks are thus associated with
the following situations:
• Steam jets exiting an accidentally
triggered gun that has not been properly
connected to its support could cause burns.
• Allowing work to be carried out on the
interior of the machine by unauthorised
personnel or carrying out such work with
the plug inserted in the mains socket.
To prevent accidents always observe the
instructions in this Manual. Should you
have any doubts at all please contact the
Manufacturer or your Authorised Servicing
Centre.
The steam generator, where the user fails
to observe the instructions contained
in this manual, is a potential source of
explosion or fire. Should you have any
doubts whatsoever, always contact the
Manufacturer or an Authorised Service
Centre.
The above-mentioned dangers are indicated
by special labels attached to the equipment, as
described in sub-section 3.4.1.
CHAPTER 8: MAINTENANCE
8.1 CLEANING THE EQUIPMENT
The equipment exterior can normally be kept clean
just by wiping it with a dry cloth. If necessary, wet
the cloth just a little water or use a non-degreasing
detergent (see section 2.4). The operator must

EN
33
vap 8 - vap 8A - AD8
The reference figures can be found on pages 3, 4, 5, 6 of this manual.
ensure that the equipment is kept clean and free
from any foreign bodies such as dirt, water, non-
conducting liquids etc. Cleaning should be carried
out at the end of every work session and must be
done with the equipment switched OFF and stable.
To clean the water tray (8), pull out the bottom
part so as to detach it from the appliance.
If you need to clean the interior of the unit contact
an Authorised Service Centre.
• Before cleaning the equipment exterior
always turn the main switch to OFF. It is
strictly forbidden to clean the equipment
while it is connected to the mains power
supply.
• Never use inflammable, corrosive, alkaline
or toxic liquids when cleaning the
equipment.
If using compressed air for cleaning,
always wear a face protection visor, keep
people away from the appliance, as they
may be struck by the material being
sprayed off, and ensure a minimum
pressure of 2 bars.
8.2 ROUTINE MAINTENANCE
Once the equipment has been cleaned (see
paragraph 8.1), the operator must check for worn,
damaged or loose parts. If any such situations are
detected, contact the Authorised After-Sales Centre.
If any of the previously-described situations
should occur, it is prohibited to re-start the
equipment before the problems have been
solved.
In particular, before moving away from the
equipment, the operator detecting problems of
any nature must place a sign on the it indicating
that equipment maintenance is in progress and
that use is prohibited (EC-compliant signs can be
purchased from the relevant suppliers). Routine
maintenance, cleaning and correct equipment use
are essential factors in guaranteeing long-lasting
equipment performance and safety.
Equipment safety devices/guards must
never be removed except for repair and
maintenance purposes. Such items must be
replaced as soon as the situation which led
to their removal no longer exists and in any
case before the equipment is used again.
8.3 EXTRAORDINARY MAINTENANCE
Extraordinary maintenance includes the repair of
any accidental breakage and the replacement of
worn or malfunctioning parts.
All electrical and mechanical interventions
must only be performed by a Zhermack
S.p.A.-authorised maintenance technician.
Any modification that alters equipment
features from a safety and risk-prevention
point of view can only be carried out by the
Manufacturer who will then certify
conformity of the equipment with safety
standards. Therefore any modification or
maintenance intervention not considered in
this manual is to be considered prohibited.
Any modification, tampering or repair
performed by unauthorised staff along with
the use of non-original spare parts relieve
the Manufacturer from any liability. If the
necessary maintenance interventions are not
considered in this Use and Maintenance
Manual, contact the Authorised After-Sales
Centre.
8.3.1 EMPTYING THE WATER FROM THE BOILER

CHAPTER 9: DIAGNOSTICS
9.1 GENERAL WARNINGS
If any of the anomalies described below
should occur, solve the problem, where
allowed, with respect to all instructions
contained in this manual. If the problem
persists, contact the Authorised After-Sales
Centre.
9.2 TROUBLESHOOTING
PROBLEM After switching on the equipment via
the main switch the LED on the key fails
to come on.
CAUSE 1. The power cable is not plugged in.
2. There is no current to the socket.
3. Blown fuse.
4. Electrical fault.
REMEDY 1. Plug in the power cable.
2. Check the socket/electrical panel in
the building.
3. Replace the fuse (T 10 A).
4. Contact an Authorised Service Centre.
PROBLEM During start-up of the VAP 8 the
indicator light (4) stays on for longer
than 5 seconds.
CAUSE 1. No water/not enough water in the
boiler.
2. Electrical fault.
REMEDY 1. Add distilled water to the boiler (see
section 6.6.1).
2. Contact an Authorised Service Centre.
PROBLEM The electric pump on the VAP 8A fails to
fill the boiler with water.
CAUSE 1. Automatic pump shutdown on
account of the overheating caused
by high pressure or no water in the
boiler.
REMEDY 1. Proceed as per point 1 of section 7.2.
PROBLEM Steam generator overpressure warning
light comes on.
CAUSE 1. Safety pressure switch has tripped
because pressure is higher than 8 bar,
thus shutting down the machine.
2. Electrical fault.
REMEDY 1. Proceed as per point 2 of section 7.2.
2. Contact an Authorised Service Centre.
PROBLEM Steam generator safety valve has
opened.
CAUSE 1. Steam generator malfunction.
REMEDY 1. Switch off the equipment and contact
an Authorised Service Centre.
PROBLEM The pressure in the boiler drops
considerably when the gun trigger
button is pressed or noise is heard
inside the boiler when the element is
on.
CAUSE 1. Low pressure inside the boiler due to
steam condensation.
REMEDY 1. Press the gun trigger for a few
seconds with the equipment on.
PROBLEM
the pressure gauge indicates a pressure of more
than 8 bars.
SOLUTION
A certain difference from the nominal value is
normal and is explained by the tolerances of the
internal components (in this specific case, the
pressure switch and pressure gauge). Operation
at a higher pressure, even up to 9 bars, does
not compromise boiler safety. In addition to the
operational pressure switch, the steam generator is
also fitted with a safety pressure switch which trips
at 9.5 bars and a certified safety valve which trips
at 12 bars. Moreover, the boiler is certified to resist
up to 24 bars.
PROBLEM
there are drips from the fixed nozzle or gun.
SOLUTION
drips from the fixed nozzle or gun may have two
main causes. If the drips appear shortly after use,
they are caused by condensation of the steam
in the circuit and are normal. If the drips are
continuous, they are most probably caused by

EN
35
vap 8 - vap 8A - AD8
The reference figures can be found on pages 3, 4, 5, 6 of this manual.
incorrect demineralisation of the water, leading to
leaks of steam from the solenoid valve as a result
of limescale or dirt.
PROBLEM
the steam generator is noisy.
SOLUTION
some noises are normal and attributable to the
technical characteristics of steam generators. When
starting up the VAP 8 A for the first time, you may
hear a sometimes loud noise caused by priming of
the pump. During use of both the VAP 8 and VAP
8 A, it is normal to hear cracks or gurgles during
the steam generation phase. During start-up, their
intensity can be reduced by venting the air in the
circuit by pressing the button on the gun or the
fixed nozzle.
