Operation; Preparing For Start-Up - VWR VP 86 Manual De Instrucciones

English
6.2 Connection
 Only connect components to the pump which are designed for the pneumatic data of the pump (see
chapter 4).
 If the pump is used as a vacuum pump, safely discharge the pump exhaust at the pump's pneumatic
outlet.
A marking on the pump head shows the direction of flow.
1. Remove the protective plugs from the pneumatic connectors of the pump.
2. Mount accessory parts filter or silencer (if present).
If the pump is used as a vacuum pump, mount a silencer at the pressure side if necessary. If the pump
is used as compressor, mount a filter at the suction side if necessary.
Before mounting the filter or silencer, unscrew the corresponding hose connector from the threads in
the pump head.
3. Connect the suction line and pressure line (tube ID 4 mm).
4. Lay the suction and pressure line at a downward angle to prevent condensate from running into the
pump.
5. Insert the power cable's plug into a properly installed shockproof socket.

Operation

7.1

Preparing for Start-up

Before switching on the pump, observe the following points:
Operational requirements
Pump  All hoses attached properly
Fan openings not blocked

 Specifications of the power supply correspond with the data on the pump's type plate.
 The pump outlet is not closed or constricted.

7.2 Starting
 Only operate the pump under the operating parameters and conditions described in chapter 4, Technical
data.
 Make sure the pump is used properly (see chapter 2.1).
 Make sure the pump is not used improperly (see chapter 2.2).
 Observe the safety precautions (see chapter 3).
Hazard of the pump head bursting due to excessive pressure increase
 Do not exceed max. permissible operating pressure (see chapter 4).
 Monitor pressure during operation.
 If the pressure exceeds the maximum permissible operating pressure, immediately shut
WARNING
down pump and eliminate fault (see chapter 9. Troubleshooting).
 Only throttle or regulate the air or gas quantity in the suction line to prevent the maximum
permissible operating pressure from being exceeded.
 If the air or gas quantity in the pressure line is throttled or regulated, make sure that the
maximum permissible operating pressure of the pump is not exceeded.
Pump standstill
 With the pump at a standstill, open pressure and suction lines to normal atmospheric pressure.
