3.2 Compressed-air port
The connection to the compressed-air duct-
work 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 compres-
sor is connected.
Use a flexible hose to connect the
compressor to the supply network.
Thus, stress cracks and sound bridges
are prevented.
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 volt-
age.
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 cir-
cuit diagram in the chapter titled
“Technical annex” or in the switch cab-
inet as well as to the following connec-
tion conditions.
Checking the rotating direction
Caution
Fire hazard and damage to compressor
in case of wrong polarisation of the
motor.
Carry out the check of the rotating di-
rection as described below:
Please refer to chapter 4.2 titled “Switch-
ing the unit on”.
Briefly switch the operating switch on and
off. The correct rotating direction of the
fan has been marked by an arrow on the
fan cover.
Change the poles of the electric connec-
tion of the motor in case of a wrong rotat-
ing direction.
