Cooling
The vacuum pump is cooled by
–
radiation of heat from the surface of the vacuum pump
–
the air flow from the fan wheel of the drive motor
–
the process gas
–
the air flow from the fan wheel on the shaft of the vacuum pump
On/off Switch
The vacuum pump comes without on/off switch. The control of the
vacuum pump is to be provided in the course of installation.

In case the vacuum pump is in a cardboard box cushioned with rolled
corrugated cardboard:
◆
Remove the corrugated cardboard from the box
In case the vacuum pump is laid in foam:
◆
Remove the foam
In case the vacuum pump is bolted to a pallet or a base plate:
◆
Remove the bolting between the vacuum pump and the pal-
let/base plate
In case the vacuum pump is fastened to the pallet by means of tighten-
ing straps:
◆
Remove the tightening straps
CAUTION
_af

●
Make sure that the eyebolt (a) is in faultless condition (replace a
damaged, e.g. bent eyebolt with a new one)
●
Make sure that the eyebolt (a) is fully screwed in and tightened by
hand
●
Attach lifting gear securely to the eyebolt (a) on the synchronising
gear
When the vacuum pump is equipped with a very heavy drive motor
and would hang very inclined (>10 °) on the synchronising gear
eyebolt alone:
◆
Attach lifting gear securely to the eyebolts on the synchronis-
ing gear (a) and on the drive motor
In case the drive motor comes without an eyebolt or the eyebolt on the
drive motor is located at an unfavourable position:
◆
Loop a belt/rope with suitable length and strength around the
flange of the drive motor
●
Attach the lifting gear to a crane hook with safety latch
●
Lift the vacuum pump with a crane
In case the vacuum pump was bolted to a pallet or a base plate:
◆
Remove the stud bolts from the rubber feet
Storage
Short-term Storage
●
Make sure that the suction connection and the gas discharge are
closed (leave the provided plugs in)
●
Store the vacuum pump
