Fundamental safety instructions

1 Fundamental safety instruc-

tions

1.1 Designated use

The compressor system is intended exclu­sively for the generation of compressed air.
Any other use shall be considered an undes­ignated use.

1.2 Fundamental measures

• Never point compressed air at persons.

• Observe these operating instructions.

• Keep these operating instructions avail-

able at the location of use at all times.

• Please observe the regular maintenance
intervals (refer to chapter 6 “Maintenance
schedule”).

• Use original BLITZ parts and approved
operating material only.

• Do not use compressed air for breathing
without corresponding treatment.

• Do not modify the system.

• Use mounting parts and devices down-

stream from the compressor which have
been designed for the maximum operating
overpressure of the compressor.

• In your capacity as proprietor, please en­sure that all safety regulations are ob­served by the operating staff.

• Do not use the compressor as a climbing
aid.

1.3 Description of symbols and

notes

Danger

Mortal danger and risk of injury.

Caution

Damage to property.

Information and tips.

2 Transport and storage

2.1 Transport

Danger

Mortal danger caused by incorrect
transport.

• Do not hold the compressor at its
cladding elements as you lift it.

• Only use suitable lifting gear with the
corresponding weight-bearing capacity
(for data on weight, please refer to
chapter “Technical annex”).

• Fasten and secure the system with
belts at the corresponding points.

• Secure swivelling and loose parts.

• Transport the compressor by means of

crane hooks, fork-lift truck and elevat­ing truck only.

• Never remain under suspended loads.

• Depressurise the compressor prior to

any transport.

2.2 Storage

Store the compressor in a dry location pro­tected against weather influence. Ambient
temperature: -10°C to +50°C.

Please order the BLITZ conservation instruc­tions in case of storage of over six months.

For information on recommissioning
after an extended idle time, please re­fer to chapter 4.3.

Mounting

3 Mounting

3.1 Mounting conditions

!

Check the compressor for damage during
transport.

Ambient conditions

Danger

Mortal danger and explosion hazard
when caustic, inflammable or poison­ous gases are drawn in.

• Do not operate the compressor in ex­plosive surroundings or in the vicinity
of open flames and flying sparks.

Caution

Wrong mounting will cause damage to
the compressor.

• Ensure sufficient ventilation of the
compressor room.

• Do not operate the compressor in the
open.

• Systems with a capacity exceeding 40
kW must be installed in such a way
that no combustible objects or materi­als are in the immediate proximity.

• Systems with a capacity exceeding 100
kW should be installed in a separate
room.

The space between the compressor and the
wall has to be at least 60 cm (cf. fig. 3: Loca­tion). The compressor has to be easily acces­sible from all sides. The ambient temperature
must be between 3°C and 40°C.

Cooling and exhaust air

Danger

Mortal danger and explosion hazard
during suction.

• Ensure that the compressor draws in
only clean air which is free from nox­ious constituents. Noxious substances
are liable to accumulate in the lubricat­ing oil of the compressor. They may
cause explosions in the system and se­vere damages.

• Do not allow objects or pieces of cloth­ing of persons going past to be sucked
in by the intake air flow.

Operating instructions

Mounting

The overall length of all intake air ducts and
exhaust air ducts must not exceed 4 m; one
baffle is permissible. In case of ducts exceed­ing this length or in case of several baffles,
filters, grids etc., a booster fan must be in­stalled. In this case, please contact your tech­nical adviser.

For further information on the required venti­lation cross sections, please refer to the
Technical Annex.

Ground

!

Place the compressor on a horizontal and
plane surface.

The ground has to have a suitable load­bearing capacity. BLITZ offers special solu­tions for inclined surfaces.

BLITZ recommends the use of rubber-metal
connections to prevent vibrations.

3.2 Compressed-air port

The connection to the compressed-air duct­work system may be carried out only by
trained experts or by staff members of BLITZ
Company.

Danger

Danger of injury by pressure in the
pipes.

• Vent the pipes to which the compres­sor is connected.

Use a flexible hose to connect the
compressor to the supply network.
Thus, stress cracks and sound bridges
are prevented.

• Compressed-air lines, filters, aftercoolers
and vessels must be equipped with an out­let for the accumulated condensation wa­ter at their lowest spots. These outlets
must allow to observe the draining con­densation water. Condensation water may
contain oil! In draining the condensate, all
applicable regulations on the disposal of
waste water must be complied with.

• Remove all securing devices before
mounting the conduits.

• Use only suitable supply lines and cou­plings which are designed for the intended
working pressure. Do not use any defect
components.

• Supply lines must not be subjected to
stress or tension.

Observe the technical data for the connection
of compressed air (cf. chapter “Technical
annex”).

3.3 Electrical connection

The connection to the electrical power system
may be carried out only by adequately trained
expert.

Danger

Mortal danger caused by electric volt­age but also by rotating wheels, V­belts, and fan blades.

• Test runs are permissible only if all

parts of the casing are closed (excep­tion: check of the rotating direction).

Compressor systems have to be fitted with a
power switch or a plug connection to interrupt
the power supply. Compressor systems with a
motor capacity of more than 3 kW or 16 Amps
have to be fitted with a lockable power switch
and upstream fuses.

In this respect, please refer to the cir­cuit diagram in the chapter titled
“Technical annex” or in the switch
cabinet as well as to the following
connection conditions.

Check and retighten where appropriate
all electric terminals before first com­missioning.
