2 Safety
Please observe the accident prevention regulations for condensers (VBG 16), especially section IIIC
“Installation” and IV “Operation” and VBG 4 “Electrical systems and equipment”.
The vacuum pump may only be modified or changed with the approval of the manufacturer.
The vacuum pump generates a lot of heat: Install the vacuum pump so that hot surfaces cannot be touched
or protect the movement range, cordon off the area or attach warning signs.
3 Intended use
The vacuum pump is used to generate underpressure (vacuum). The figures apply to a height of 800m above NN. It is not
suitable for transporting or compressing toxic or flammable media. Run the vacuum pump so that only normal atmospheric air
can be drawn in. If media containing dust are transported, the temperature must remain below the ignition temperature of the
resulting dust air mix.
The vacuum pumps are designed for operation with the following operating liquids:
with a pH value of 6 to 9, free of solids (such as sand, for example)
usually normal tap water
if other pH values or operating liquids are used, the service department must be contacted
All other uses shall be considered abuse and are prohibited!

6.4 Connecting the pipelines and hoses
Ensure that pipelines are appropriately sized and clean (no welding beads, chips or other soiling). Attach lines of at least the
same diameter as the connection threads. If the lines are more than 2m long, use then next largest diameter. Keep the
connections free of oil, grease, water or other soiling.
Suction nozzle
Removing the cap
In order to prevent foreign bodies entering, the connection opening at the suction nozzle (pos. A) is sealed on delivery.
Only remove the cap immediately before connecting pipelines/hoses.
Check valve
A check valve must be attached to the suction nozzle (pos. A) in the following cases:
If two or more systems are run in parallel, e.g. reserve system. (Note: a separate check valve must be attached to the
suction nozzle for each system)
If a vacuum can occur in the connected suction line for more than 5 minutes when the system is switched off
The check valve prevents transported gases/vapours flowing back out of the system if the machine is stopped.
Connecting the suction line
Connect the machine-side line for the gases/vapours (suction line) to be
transported to the connection piece of the suction nozzle (pos. 037).

7.2 Switching off
The system can be switched off from any operating condition (i.e. regardless of current pressure, temperature etc.).
However, please check whether the current machine work process allows system operation to be stopped.
Proceed as follows:
Switch off the power supply.
The system stops drawing the transported gases/vapours.
If the system is to be idle for an extended period:
Follow the instructions in the “Shutting down and extended downtime” chapter.
8 Operation
Starting and stopping in normal mode is identical to the procedure for initial startup.
8.1 Use in the working process
The unit can be used continually at maximum vacuum or minimal suction pressure (against a close suction slider). The power
consumption of the system is lowest when used in this way.
When idle, we recommend running at minimal suction pressure (lowest power requirement).
STANDARD HIGH VACUUM
When operating at low suction pressure (≤ 20kPa abs.), the suction capacity of the system
can be increased by switching the three-way valve (pos. G) to HIGH VACUUM.
When operating with suction pressures ≥ 20kPa abs., this valve setting can cause water spray to form on the outgoing air
nozzle.
Operating fluid loss
With lower air moisture and high suction pressure (> 35kPa abs.), the water vapour content of the exiting gases is slightly
greater than the gases drawn in. This results in loss of operating liquid.
Check the supply of operating liquid in the condenser regularly.
Do not use the system when the operating liquid level points to 0!
Liquid level at 0:
At a liquid level with the indicator at 0, the suction capacity of the system is reduced. If the system is operated under these
conditions for extended periods, the vacuum may be broken, which could cause the system to run dry!
Take the following measures when the indicator reaches 0 (minimum):
Stop the system. See “Switching off” chapter.
Fill the condenser via the fill opening with operating liquid (to indicator position 1 (lower edge of the fill opening).
Max. operating liquid level:
Lower edge of the fill opening = Indicator position 1 of the fill level indicator.
Do not fill the condenser past this liquid level!
Supply regulator
For maintenance-free operation, the vacuum pumps are equipped with a supply regulator as standard.
The supply regulator automatically adjusts the liquid level for operating liquid loss.
See appendix for structure and installation of the supply regulator.

e-mail: schmalz@schmalz.de
Operating fluid gain
The steam content of the emerging gases is slightly less than that of the gases drawn in if the humidity is high and the suction
pressure is low. This results in slight gain of operating liquid.
If water is also transported via the suction line, there is also a gain in operating liquid.
Check the supply of operating liquid in the condenser regularly.
Overfilling cannot be checked via the fill level indicator!
Do not use the system when the operating liquid level is above 1!
Drainage regulator
A drainage regulator must be connected for operating liquid gain, to automatically adjust the liquid level for operating liquid gain.
Please consult your vendor.

10 Servicing
10.1 Maintenance
The system requires little maintenance.
The following maintenance work is required:
If water with a high lime content is used as the operating liquid, the operating liquid must be softened or the entire
system and the integrated unit must be de-limed at regular intervals.
Check hoses and hose connections for possible leaks and secure fit!
If dirt or solid matter (e.g. dust or sand) or lime deposits enter the system via the operating liquid and/or the
gases/vapours transported, it must be cleaned regularly. This prevents the running wheel becoming jammed and wear
to individual parts of the system.

condenser.
Remove the pipeline/hose from the threaded nozzle (pos. H) of the integrated unit. To
do so, open the clamp using a special pliers or screwdriver.
Use 10% ethanoic acid as a de-liming liquid.
WARNING: Ethanoic acid can be dangerous! Ethanoic acid can cause serious caustic
burns! Observe the hazardous substance law (Gefahrstoffverordnung) §20, and the
safety data sheet of the manufacturer!
The interior of the integrated unit must be filled with de-liming liquid.
Proceed as follows:
Pour the de-liming liquid into the open threaded nozzle (pos. H) using a funnel. See
“Specifications” chapter for fill quantity. The entire interior of the integrated unit must
be filled with de-liming liquid.
CAUTION: Various seals in the system may be damaged by extended contact with
ethanoic acid. The ethanoic acid may only enter the interior of the integrated unit.
Allow the de-liming liquid to work for at least 30min.
During this time, turn the shaft on the fan wheel by hand occasionally.
Position a collecting container under the system.
Drain the integrated unit. Open the G¼ drain hole (Pos. E) of the integrated unit. The
de-liming liquid flows downwards through the opening in the base of the condenser.
The condenser is not chemically affected by this. Close the drainage hole again.
Attach the removed pipeline/hose to the threaded nozzle (pos. H) of the integrated
unit.
Attach the cover plate (pos. 064) and the protective grille (pos. 058) to the condenser
again.
Re-assemble the system fully.
The de-liming liquid can be poured down the drain.
OR
De-lime the entire system.
Depending on the operating conditions and the lime content of the operating liquid, it may be
necessary to de-lime the entire system. Proceed as follows:
Use citric acid as a de-liming liquid.
Pour citric acid into the system via the fill opening (pos. 007). See the
“Specifications” chapter for the fill quantity of pure citric acid (granulated) for an
average filling of the system with operating liquid.
Run the system approx. 10h with the operating liquid containing citric acid. The citric
acid dissolves the lime.
Then drain the system as described in the “Draining” chapter.
Flush the system repeatedly with clean water.

10.3 Service/customer service department
Our service department (see cover of these operating instructions) is available for work (in particular installation of spare parts
and maintenance and repair work) not described in the operating instructions.
When returning systems, please note the following:
Before shipping:
– Drain the system complete as described in the “Draining chapter”.
– Clean the exterior of the system (observe protection class in accordance with rating plate)
The system must be delivered in its entirety, i.e. not dismantled
Use the original packaging only for shipping.
A declaration of clearance form must be included with the delivery, as described in the “Decontamination and
declaration of clearance” chapter.
The original rating plate of the system must be correctly attached, intact and legible. All guarantee claims are void for
systems which are sent for damage evaluation without an original rating plate or with a damaged original rating plate.
The manufacturer must be informed of use conditions, operating hours etc. and other more detailed data if requested for
guarantee claims.
10.4 Decontamination and declaration of clearance
Danger: combustible, caustic or poisonous substances!
For the protection of the environment and persons:
Systems which have come in contact with hazardous substances must be decontaminated before they are
sent to a workshop!
A so-called declaration of clearance must be included with every system submitted to a workshop for inspection, maintenance
or repair.
The declaration of clearance
is printed in the appendix as a form for photocopying,
is legally binding,
must be completed and signed by authorised qualified staff,
must be issued for each system sent (i.e. a separate declaration for each system),
must be attached to the exterior of the packaging of the system,
should also be sent as a copy e.g. per fax to the workshop in question.
This guarantees
that the system has not come into contact with hazardous substances,
that systems which have come into contact with hazardous substances have been sufficiently decontaminated,
that the inspection, maintenance or repair staff can take appropriate protective measures if necessary.
Inspection/maintenance/repair of the system in the workshop will not begin until the declaration of clearance
has been submitted.
If the declaration of clearance is not supplied, delays may result!
11 Disposal
Have the entire system scrapped by a suitable disposal company. No special measures are required.
For further information on disposing of the system, please contact the service department.
