WARNING
Unqualified personnel
Inappropriate handling may cause serious injury or property damage.
Only qualified personnel are allowed to carry out the described work.
WARNING
Heavy weight
Physical overstraining.
Use a crane to lift the product.
4.1 Unpacking
Handling of the valve must take place under clean conditions normally observed in good
vacuum practice. The valve may only be touched with clean gloves. After the protective
covers have been removed, the sealing surfaces of the flanges have to be cleaned carefully
with alcohol. The screws of the flanges have to be tightened uniformly in diagonal crosswise
order. Determine that the valve and existing plumbing in the vacuum system will be
adequately supported.
•Make sure that the supplied products are in accordance with your order.
•Inspect the quality of the supplied products visually. If it does not meet
your requirements, please contact VAT immediately.
•Store the original packaging material. It may be useful if products must be
returned to VAT.
Open the plastic bag protecting the valve only at the points where you need
access to the eyebolts (1) for fastening the crane hooks; see below. Keep
valve in the plastic bag until it is being installed into the system.

NOTICE
Wrong lifting
Valve may crash and get damaged.
Use only the eyebolts shown in the dimensional drawing and in on sample
picture to lift the valve. Using any other components (e. g. position indicators,
solenoids) to lift the valve is strictly forbidden.
NOTICE
Sensitive product
Valve parts may get damaged.
–
When lifting the valve, pay attention that the valve does not touch any solid
objects.
–
Lift valve carefully and put it down on a clean surface or mount it to a clean
system.
Use a crane for lifting valve out of the transport box
To see the Weight of valve, take a look into the product data sheet.

4.2 Installation into the system
The valve must not support other components and has to be protected from forces of the
system (e.g. by bellows sections).
WARNING
Movable parts
Human body parts may get jammed and severely injured.
Do not connect or supply electrical power and compressed air before the
product is completely mounted in the system.
NOTICE
Contamination
Product may get contaminated.
Always wear cleanroom gloves when handling the product.
NOTICE
Force effect from other components of the system
Valve body may get deformed and/or malfunctions may occur.
– Do not use valve to support other components.
– Make sure that forces from other components do not impair the valve;
use bellows sections, for instance.

4.2.1 Preparation for installation
WARNING
Danger of injury in case of insufficient skills
Inappropriate handling may cause serious injury or property damage.
Make sure that the valve does not topple or fall down while removing the
protective covers from the flanges.
NOTICE
Sensitive product
Valve parts may get damaged.
When removing the protective covers from the flanges, be careful to avoid
damage to the valve.
1. Remove plastic bag.
2. Remove screws, Nuts and protective covers
3. Remove O-rings.
Store protective covers, O-rings, nuts and screws. They may be useful when
valve needs to be repacked.
4. Clean sealing surfaces with cleanroom wiper soaked with pure alcohol (Isopropanol).
5. Clean sealing surface with clean, oil free compressed air.

4.3 Compressed air connection
WARNING
Valve in open or closed position
Risk of injury when compressed air is connected to the valve.
Connect compressed air only when:
– valve is installed in the vacuum system
– moving parts cannot be touched
NOTICE
Wrong sequence of connections
Valve mechanism may get damaged when electrical power is being
connected before compressed air is connected.
Always connect compressed air before connecting electrical power.
Check if the circlip connecting the lid to the cylinder is in the proper position.
Use clean, dry or slightly oiled air only.
Admissible air pressure range, see product data sheet.
Check if the circlip connecting the lid to the cylinder is in the proper position.
Supply compressed air pressure only after the supply line is properly
mounted to the actuator.
Execution Procedure
Without solenoid Connection OPEN for air supply
With solenoid Connection «1» for air supply, connection «3» for exhaust

Parts being under voltage will result in serious injury or death.
Do not touch parts being under voltage.
NOTICE
Wrong sequence of connections
Valve mechanism may get damaged when electrical power is being is
connected.
Always install the valve into the vacuum system before connecting electrical
power.
NOTICE
Wrong voltage
Electrical components may get damaged.
Supply electrical components with the correct voltage.
