RECOMMENDED PRECAUTIONS
Before opening the packaging check carefully for
signs of damage and verify that the Shockwatch
indicator is not red. If it is red, accept the delivery
“with reservations” after making sure that the
equipment is in perfect condition.
Once you have removed the equipment from the
packaging, dispose of packaging materials in
compliance with current regulations. Installation
must be performed by a skilled person using
suitable tools.
The Blok-Jet Silent unit must be placed in a clean
area, away from heat sources, humidity and dust.
Temperature in the plant room must be between
+5 °C and +35 °C.
If ventilation or air conditioning is needed in the plant
room, the ventilation or air conditioning system
should be designed by a thermal engineer. The
plant room must not be accessible to patients or the
public. Put into place protections and danger signs
in order to prevent accidental contact as this can
cause electric shock and, in some rare but possible
situation, fire, explosion, leakage of contaminated
liquids and air.
No flammable material should be stored in the plant
room; ensure that there is no possibility of gas leaks
in the room. Do not connect damaged equipment
to the power mains; do not use extension cords,
multiple sockets or plugs. Before connecting the
unit to power mains, ensure that the line conforms
with C.E.I. 64-8 standards and that there are two
thermal switches with 16A differential with class
“A” or “B” in accordance with EN 61008-1.
ASSEMBLY AND STARTUP

ASSEMBLY AND CONNECTIONS
Blok-Jet Silent 1 and 2 are designed for surgeries
that need to reduce footprint and noise, they can
be installed indoor provided the air exhausted by
the suction unit is conveyed outside and the air
for the compressor is supplied from the outside.
We recommend you treat exhaust air and the
air supplied to the compressor with HEPA H14
antibacterial filters.
Compressors and suction units are installed inside
the Blok-Jet Silent units.
Blok-Jet Silent 1 is complete with an AC200
compressor and a Micro-Smart suction unit
(optional amalgam separator available).
Blok-jet silent 1 is designed to service two chairs
simultaneously.
Blok-Jet Silent 2 is complete with an AC300
compressor and a Turbo-Smart version “B” **
suction unit (optional amalgam separator available).
Blok-jet silent 2 is designed to service four chairs
simultaneously.
When Blok-Jet Silent 1 and 2 work respectively for
2 and 4 chairs, their software automatically adjusts
machine operation for energy consumption to suit
the number of users utilizing the suction unit and
compressor.
**Password must be ordered separately and its cost is not included in
that of Blok-Jet Silent 2.

cod: ed. 09-2021
Make sure that the suction tubes are clear from
debris. Insert the Ø 50 mm tube provided into
“SUCTION” inlet no. (9), connect the suction of the
Blok-Jet Silent unit to the central system of the
clinic. Connect the Ø 50 mm heat-resistant tube to
tube holder (10) (“EXHAUST AIR”). Exhausted air
can be connected to an antibacterial filter (optional)
and to a silencer (optional). Hot exhausted air must
be conveyed outside. The liquids separated by the
suction unit of Blok-Jet Silent will be conveyed, via
the Ø 20 mm hose connected to the WASTE WATER
hose connector no. (8), into the drain of the clinic,
which needs to be on a lower level. Connect the Ø 8
mm tube holder (11) (“SAFETY WASTE WATER”) to
the liquid drain. The tubes connecting the machine
to the suction system are flexible in order to dampen
the small vibrations produced by the operation of
the suction unit. When Blok-Jet Silent is installed on
a lower level than the surgeries, the suction piping
must go down to the level of the suction unit, with
a couple of metres of piping laid horizontally on the
same level before connecting with the suction unit.
This will remove the acceleration that the liquids
produce when flowing down from the surgeries.
Before starting the compressor ensure that the
tubes are clean. With the Ø 10 mm tube inserted
in tube holder no. (7), connect Blok-Jet Silent to
the compressed air system of the clinic. Connect
the condensate drain tube provided to tube holder
no. (6). Carefully read the data plate on your Blok-
Jet Silent, check power voltage and frequency;
incorrect power supply can damage the equipment,
compromise its operation and cause fire. When
assembly is complete, connect the power cable
of the suction unit (2) and the power cable of the
compressor (1) in accordance with regulation EN
61008-1. Connect the permissive (clean contact)
(4) arriving from the dental units. Ensure that the
contact is clean (not live). Lastly, connect the alarm
signals (3-5) to the reception desk.

Blok-Jet Silent is equipped with an internal
ventilation system which, taking air from the room,
lowers the internal temperature produced by the
equipment during operation.
The room will also have to be equipped with a
ventilation system, with exhaustion and an inlet
for air supply, in order to guarantee a flow that
will maintain room temperature in the range
+ 5 °C to 35 °C. Install the Blok-Jet Silent in a clean
environment, away from sources of heat, humidity
and dust. When installed outdoors (on balconies,
porches and in gardens) protect the machines
from rain, water splashes, moisture, freezing
temperatures and direct sunlight.

When Blok-Jet Silent is installed on a lower level
than the surgeries, the suction piping must go
down to the level of the suction unit, with a couple
of metres of piping laid horizontally on the same
level before connecting with the suction unit. This
will remove the potential energy that the liquids
produce when flowing downward.

STARTING UP, TESTING AND INSTRUCTING PERSONNEL
Once you have assembled and electrically connected
the Blok-Jet Silent, simply switch on the unit (1) and
send the permissive signal from one of the dental units
connected, to activate the suction unit and compressor.
The compressor will start and fill the tank to the desired
pressure of 8 bar see (2). Instructions to personnel on
operationand ordinary maintenance must be given before
the unit is used so that it is not contaminated. Surgery
personnel must be shown how to follow the stages of
operation of the Smart suction unit on the display (5), to
interpret danger warnings and light signals (3-4) and to
correctly carry out maintenance operations with Puli-Jet
plus new, Pulse Cleaner and antifoaming tablets.
STARTING UP, TESTING AND
INSTRUCTING PERSONNEL
COMPRESSOR AC200 AND AC300
OPERATION
Air enters the cylinder through a filter 6, undergoes an
initial filtration which removes airborne dust, improves
its quality and protects piston and cylinder. The piston
travels inside the cylinder without lubrication; the
material that covers the piston and the material of
the cylinder liner are compatible and, despite the
relative motion, will not be subject to significant wear.
For this reason, our maintenance instructions do not
recommend replacing the elastic band and piston at
any time throughout the life of the compressor. In the
cylinder, air is compressed and heated up to 100/120°C,
it is thus necessary to pass it through the air-to-air
exchanger (9) where, at an ambient temperature of
about 20 °C, ΔT at the exchanger outlet will be approx.
5 °C. The compressed air must be cooled in order to
reach the dew point, which is a necessary condition for
condensation of the water vapour present in the air. In
the dryer column, (12) air passes through the cyclone
where it deposits water, then it goes through a silica gel
mix with high adsorbent power, where it is further dried.
After leaving the drying column, air passes through two
filters: the first one is sintered bronze, the second one
polyester; the polyester filter may be replaced with a
Hepa H14 filter. The dried and hygienically filtered air
goes into the tank (10), ready to be used. The inside of
the tank is covered with a certified food grade resin to
guarantee good preservation. In this respect, we are
still considering whether to use an antibacterial food
grade resin. While the tank is filling, air also enters the
small tank (8) through a selective valve (7). At the end of
each charge, the dry air in the small tank counter-flows
through the drying column to regenerate the silica gel.
This occurs because this return air drags with it all of
the water previously removed from the incoming air and
conveys it into the bottle. The entire process described
above takes place automatically.

The suction assembly (9) (through tube 10) creates
vacuum in the centrifugal separator (11). The fluid
received from the surgeries, through the manifold
tube (2) flows into the centrifugal separator (11).
The centrifugal separator separates air from
liquids: the air is exhausted outside through tube
no. (4) while the liquids (if there is no amalgam
separator) are drained into the sewage through the
drain tube connected to the tube holder (6).
The centrifugal separator (11) starts before the
turbine (9), this time delay makes it possible to
eject any liquids that may have accumulated in the
centrifugal separator, before suction starts. When
the machine is switched off, an adjustable timer will
keep the suction unit on for 10 to 300 seconds.
OPERATION
IL SEPARATORE DI AMALGAMA ISO
Smart suction units can be supplied complete
with our amalgam separator “Idrociclone ISO
18” for Turbo-Smart and "Idrociclone ISO 6" for
Micro-Smart. The amalgam separator is always
accompanied by an operation and maintenance
manual.
We are mentioning them because we would like to
point out operation features and benefits, especially
in terms of environment protection.
Our amalgam separators "Idrociclone ISO 6" and
"Idrociclone ISO 18" have been approved by TÜV for
amalgam separation: the first one is approved for
98.9% separation efficiency with 5.5 l/min flow rate,
the second one is approved for 98.3% separation
efficiency with 18 l/min flow rate.
Both certificates have been issued by the Essen
TÜV.

ROUTINE MAINTENANCE
COMPRESSOR AC200 AND AC300
ROUTINE MAINTENANCE TO BE CARRIED OUT BY TRAINED MEMBERS OF THE SURGERY STAFF
• Danger of electrical shock, even 230 V
can be fatal.
• High temperature.
• Generic danger sign.
• Obligatory direction of flow or rotation.
Before getting close to the compressor remove
power and make sure that nobody can restore
power without informing the person in charge
of maintenance. If the compressor is housed in a
dusty place where it can suck up solid particles
such as dust, sand, dry leaves or other, you should
frequently clean the fans of the head (7), the motor
(6) and the air-to-air exchanger (4) as well as clean
and replace the filters on the cylinder head very
often. Every 12 months, check the efficiency of
fans; the compressor cannot operate for long times
without adequate ventilation. The tap (8), located
under the air tank, must be opened regularly; if you
find there is moisture you need to call a technician.
Keep in mind that the air-drying system cannot
work well with a temperature above 35 °C. The
compressor must not start running if air is not
used; if that happens, check for leaks in the system
or in the machines that use compressed air. The
charging time is approximately 45/55 sec.; pause
time, required for the regeneration of the silica gel
and cooling, takes up about a third of the charging
time. Careful monitoring prolongs the life of the
machine: when a machine becomes noisy or creates
vibrations, it means that something is loose or worn
out, in this case call a technician. Based on their
experience and on the load of work at the surgery,
operators may decide to reduce or increase the
frequency of maintenance operations that we have
suggested.

EXTRAORDINARY MAINTENANCE
COMPRESSOR AC200 AND AC300
EXTRAORDINARY MAINTENANCE
TO BE CARRIED OUT BY A TRAINED AUTHORIZED TECHNICIAN, USING ORIGINAL SPARE PARTS
The frequency of checks is linked to the load of
work at the surgery. For surgeries working eight
hours a day, five days a week, a visit every twelve
months will suffice, provided the machines are also
monitored by staff trained for routine maintenance.
Technicians in charge of special maintenance
operations must use only original spare parts,
they must not alter the machines or their operation
and must not modify the safety devices. Most
importantly, they must not perform welds on the
compressor tank. Before intervening, refer to the
instruction manual, exploded drawings and wiring
diagrams. Before you get close to the compressor
remove power, if the main disconnection switch is
far from the compressor and cannot be visually
monitored, place a padlock on the switch.
Make sure that with each charge the compressor
reaches the maximum pressure value, the
charging time is approximately 45/55 seconds
while regeneration and cooling time is a third of the
charging time. Check electrical absorption. Every
time the compressor stops, a small amount of dry
air is counter flowed to dry the silica gel, if this is
not the case check or replace the solenoid valve
(13). When the compressor has difficulty reaching
steady state, check power voltage and condenser
capacity. Every six months check the absorptions
with clamp-on ammeter.
Check for leaks in the machine, in the pipework
and in the chairs. Check suction of each cylinder
(6 or 8 bar); the air drawn must not be less than
6000 N l/h. Replace any burned out bulbs in the
switchboard, replace any relays and contactors
that form sparks or that have worn out contacts. Do
not alter operation and electrical and mechanical
protections. Changes in operating noise may be
a sign of malfunction and danger of breaking; it
is therefore a good idea to replace noisy heads.
Check the temperature in the plant room, with a
temperature above 35 °C the air-drying system will
not operate correctly. Check that there is no water
in the tank or units. Check that routine maintenance
is performed correctly, otherwise we recommend
that you take responsibility for maintenance, with
the approval of the professional or of the owners.
Replacement of Hepa H14 filter. The Hepa H14 filter
is always delivered with an instruction sheet for
filter assembly and maintenance. In an environment
with clean air it is sufficient to clean the filters (A)
every 12 months. Before servicing the (L/S) filter
in addition to removing the current, it is necessary
to close the tap that connects the compressor
and drain out the air from the tank by opening the
tap (8). The Hepa H14 filter cannot be placed in an
autoclave. Spare cartridges are available; follow
the instructions (included in the filter).
If you need a more detailed description, we invite
you to refer to the operation manual of compressor
AC200 and AC300. You can find it on our website
