4 Installation
4.1 Installing solenoid valve
NOTICE
Property damage from impermissibly high inlet pressure
Increased inlet pressure compromises the operational reliability of the vacuum pump and causes an
increase in power consumption and operating temperature.
►Observe the max. permissible inlet pressure of 1,500 hPa (absolute).
►Dose the flushing gas quantity with the dosing screw in the gas ballast valve or on site.
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.
NOTICE
Loss of leak tightness due to improper installation of gas connections
Inadequate cleanliness when handling the pipe connections will result in leakages and potential proc-
ess damage.
►Always wear suitable gloves before touching or installing components.
►Install all seals dry and free of grease.
►Look out for damaged surfaces and sealing surfaces.
►Replace any damaged components.
Prerequisites

Installing and aligning solenoid valve
1. Apply the Loctite thread sealant economically onto the turns of the threads of both threaded nip-
ples.
2. Screw threaded nipple I into the G 1/8" filter bore in the selector switch of the gas ballast valve.
–Tightening torque: 2.5 Nm
3. Screw threaded nipple II with the lock nut into the G 1/8" bore in the valve body of the solenoid
valve.
–Tightening torque: 2.5 Nm
4. Wait for the drying time of the threaded sealant to pass.
5. By hand, screw the solenoid valve with the lock nut onto threaded nipple I.
6. Turn the solenoid valve into the desired position and screw the lock nut tight.
7. Install the external inert gas supply on the inlet side of the solenoid valve, if present.
4.2 Establishing electric connection
NOTICE

the vacuum pump.
4.3 Configuring accessories
NOTICE
Property damage to third-party electronic devices
The accessory connections on the vacuum pump do not meet any USB standard. The connection as-
signment does not comply with any standard. Depending on their configuration, the 24 V DC supply
voltage may damage or destroy third-party electronic devices, e.g. tablet computer.
►Do not connect any third-party electronic devices to the accessory connections.
►Only use the connecting sockets for pump-specific accessories.
Accessory connectors "C" and "D" are each used to connect an accessory. The software of the elec-
tronic drive unit automatically detects accessories connected to interfaces.

5 Operation
CAUTION
Danger of injuries from contact with vacuum at gas ballast connection
There is a danger of minor injuries during operation due to limbs being sucked in (hematoma) at the
open gas ballast connection.
►Keep a sufficient distance away from automatic gas inlet or ventilation systems.
►Always mount the sinter filter or a secure hose supply line at the gas ballast connection.
Important settings and function-related variables are programmed ex factory as parameters in the vac-
uum pump electronic drive unit. Each parameter has a three-digit number and a description. Parameter-
driven operation and control is supported via Pfeiffer Vacuum displays and control units, or externally
via RS-485 using Pfeiffer Vacuum protocol.
