4 Installation and operation

4.1 Connecting venting valve

NOTICE

Property damage caused by unfiltered media supply

Using unfiltered media for the gas inlet of a vacuum pump may result in particle contamination. There

is a risk of damage to, and even destruction of, vacuum components.

►Install suitable filters from the Pfeiffer Vacuum accessories range upstream of the gas inlet, be-

fore you use ambient air or other unclean media.

Prerequisites

●Vacuum pump switched off and vented

Required tools

●Hexagon wrench, WAF 14

●Calibrated torque wrench (tightening factor ≤ 1.6)

Fitting the venting valve

1. Unscrew the venting screw with sealing ring out of the turbopump by hand.

2. Screw the venting valve with the outlet side into the venting connection of the turbopump.

–Tightening torque: 2 Nm.

Connecting venting valve to turbopump

►Plug the control cable of the venting valve into one of the two accessory connections "C1" or "D1"

on the pump bottom part.

–Make sure that the Pfeiffer Vacuum logo on the connecting plug is facing up.

–The electronic drive unit software automatically resets existing configuration settings to "de-

fault" and automatically detects newly connected accessories.

Establish the venting gas supply

In case you want to use dry room air as venting gas, the venting valve is ready for operation immediate-

ly. Pfeiffer Vacuum recommends: Use a filter on the inlet side.

Installation and operation

9/16

If you wish to use a different inert gas (e.g. nitrogen N2) as the venting gas, follow the steps.

1. Provide an external venting gas supply with a maximum inlet pressure of 1,500 hPa absolute.

2. Connect the venting gas supply to the inlet side (1/8" thread) of the valve.

3. If required, use connection adapters from the valve accessories (not included in the scope of sup-

ply).

4.2 Operating venting valve

CAUTION

Risk of injuries due to contact with vacuum when venting

While venting the vacuum pump there is a risk of minor injuries due to the direct contact of body parts

with the vacuum, e.g. hematomas.

►Do not fully unscrew the venting screw out of the housing during venting.

►Keep a distance from automatic venting device, such as venting valves.

NOTICE

Damage to the turbopump due to non-permissibly fast pressure rise during venting

Non-permissibly high pressure rise rates place a significant load on the rotor and the magnetic bear-

ing of the turbopump. During venting very small volumes in the vacuum chamber or the turbopump,

there is a risk of uncontrollable pressure rises. This causes mechanical damage to the turbopump,

including potential failure.

►Observe the prescribed maximum pressure rise speed of 15 hPa/s.

►Avoid manual and uncontrolled venting of very low volumes.

►Where necessary, use a venting valve from the Pfeiffer Vacuum range of accessories.
