4.0 Installation
•
The safety valve must be secured so as to prevent
unauthorized or mistaken manipulation.
•
The safety valve must not be blocked.
•
The safety valve must not be used for controlling
the amount of air during compression.
4.5.3 Vent valve
The vent valve for the vacuum pump is
used for controlling the system and for
safeguarding the intake pipe. It must be
fitted!
The size and setting of the vent valve must be selec-
ted so as to ensure that the intake pressure is restric-
ted to the permissible minimum of 200 mbar.
4.5.4 Float valve
Where the vacuum pump is at risk of a fluid intake, an
automatically closing float valve must be fitted in the
intake pipe.
4.5.5 Pressure gauge/vacuum gauge
Design the pressure gauge/vacuum gauge according
to the maximum achievable operating pressure/
vacuum. Install immediately downstream of the deli-
very socket.
4.5.6 Thermometer
The thermometer for measuring the final compression
temperature must be installed in the pressure pipe
directly downstream of the delivery socket. It must
have an adequate range for the type of use.
The constant temperature of the compressed air must
not exceed 180 °C. Higher temperatures are briefly
permitted during vacuum operation,
4.5.7 Touch guard
The moving and hot parts of the machine must be fit-
ted with a touch guard.
4.5.8 Silencer
The air escaping from the vacuum pump produces a
loud noise. To reduce the sound level, we recommend
the fitment of our silencer.
4.5.9 Intake air filter
The air filter may only be fitted horizontally. It must not
face down towards the clean air socket, since dirt
might enter the clean air pipe during cartridge remo-
val, and may thus enter the compressor which would
affect the dust removal by the presettling tank.
It must be ensured that the arrow in the
“TOP” marking on the dust collection tank
points upwards.
4.5.10 Vacuum filter
The vacuum-tight filter provides protection against
mechanical impurities. Install in the intake pipe!
During installation note the following:
•
Direction of flow,
•
Space for changing the filter insert.
Vacuum filter SFA is not suitable for
excess pressure.
Vacuum filters of series VFD are pres-
sure surge proof up to 11 bar.
