HAZARDS
2 INTENDED
USE
The “K” series of side channel compressors-vacuum pumps in
an “MOR” format are made to generate vacuums and
pressures, and for conveying air and gas that is not explosive,
not inflammable, not poisonous, and not aggressive, for
continuous operation in a non-explosive environment.
The “K” series of side channel compressors-vacuum pumps in
an “MOR” format are designed and built for use in industrial
plants are fitted with three-phase or single-phase electric
motors of an asynchronous bipolar type, in compliance with
IEC 34-1.
2.1
TYPICAL EXAMPLES OF IMPROPER USE
THE FOLLOWING ARE STRICTLY FORBIDDEN:
- Using the unit in non-industrial installations, unless all the
necessary precautions or protective measures have been
taken (e.g. protection against contact to safeguard children).
- Using the unit in places in which there are explosive dust
and/or gas or where these may form.
- Sucking up and conveying explosive, inflammable,
aggressive, corrosive, and/or harmful fluids.
- Using the unit under conditions that differ from those
indicated in the “CHARACTERISTIC DATA” table on page 3.
- Using the unit without having installed a suction filter.
- Operating with the suction and/or delivery openings closed.
Danger due to burns caused by contact with
hot surfaces on the unit!
When operating in compliance with the values indicated in
the “CHARACTERISTIC DATA” table on page 3 the
compressors-vacuum pumps can reach high surface
temperatures of up to 160°C (+320°F).
Fit the unit with adequate protection against the risks of
involuntary contact with hot surfaces.
Do not touch the unit’s surfaces on purpose when it is
running!
Before doing any work after having switched off the unit,
allow it to cool!
Danger resulting from the impeller seizing
due to the performance values being
exceeded: Vacuum and/or pressure
exceeding the declared values!
Do not allow the unit to operate with the suction and/or
delivery openings obscured for any reason.
Install a safety valve that can prevent excessive vacuum
and/or pressure, and that makes it possible to comply with
the values indicated among the “CHARACTERISTIC DATA”
given on page 3 of this manual.
In order to limit the formation of layers of dust on the
surfaces, which may compromise natural exchanging of heat
between the unit and the environment, regularly clean and
remove all dust using suitable equipment.
Suction and/or delivery piping must not be dirty or clogged!
If any anomalous noises are heard, which may be a
warning that the impeller is about to seize, switch off
the unit and move away from it immediately.
Danger due to the impeller seizing due to use
in an unsuitable place and/or due to
conveying fluids that are not suitable:
Unsuitable ambient and suction
temperatures!
Check that the ambient and suction temperatures for the gas
conveyed are between: -15°C (+5°F) and +40°C (+104°F).
Check that good ventilation is provided for the unit.
Use a filter on the suction side to filter particles 25 µm or
larger, which will make it possible to limit the entry of any
solids into the unit, thereby avoiding possible breakage of
the impeller blades, making the fragments projected out of
the delivery opening dangerous!
During installation and when the unit is running, check for
load losses due to the use of this filter: The maximum load
loss allowed is 30 mbar. This value must be subtracted from
the maximum admissible pressure indicated in the
“CHARACTERISTIC DATA” table on page 3 of this manual.
If any anomalous noises are heard, which may be a
warning that the impeller is about to seize, switch off
the unit and move away from it immediately.
Danger due to rotating components: Cooling
fan for the electric motor!
There is an immediate danger of hair and clothing becoming
entangled in the cooling fan in the electric motor’s cowling
via the cowling itself!
Protective steps to be taken:
Do not wear loose-fitting garments, long laces, or other
items that may get entangled in the machine.
Long hair must be gathered up.
Danger due to hot surfaces – up to 160°C
(+320°F)!
Under operating conditions there is a possibility of burns due
to contact with the unit’s surfaces.
Protective steps to be taken:
Fit the unit with adequate protection against the risks of
involuntary contact with hot surfaces.
Do not touch the unit’s surfaces on purpose when it is
running!
Before starting with any work, wait for the unit to cool down
after switching it off!
Danger due to noise emitted by the unit!
When the compressors-vacuum pumps are running they
emit noise that may exceed 80 dB(A)!
Protective steps to be taken:
Mark the area around the unit using warning signs.
Wear personal protective equipment for hearing.
If necessary, fit additional silencers on the suction and/or
delivery silencers.
From time to time use noise tests to check the efficiency of
the soundproofing panels in the suction and delivery
silencers. The reference values are indicated in the
“CHARACTERISTIC DATA” table on page 3 of this manual.
Any use other than the intended use of the
unit may cause serious injury and even
death!
Failure to comply with the prohibitions / obligations indicated
may result in technical faults, damage to the plant, or injury!
Danger of very serious injury!
