Relative humidity must be <90%
The sound level depends on several factors. For examp-
le, the location of the high vacuum unit (indoor/outdoor),
the size of the room, the ambient temperature, shotdown
delay and the connection (hose><pipe) of the unit also
have an impact on the sound level.
4.0 Transport, handling and storage
During transport in a truck or in another means of trans-
portation the product must be securely packed in a box
or a pallet and covered with a water proff material.
The product must be securely stowed in the truck so that
it will neither tilt nor shift during transport.
During transport over a short distance e.g. in a stock or
a factory, the product can be moved by means of a for-
klift or a stabeler.
When moved it must be secured that the product does
not tilt or shift. And it must be secured that the limitations
of the means of transportation is not exceeded.
Secure that there are no people around the product,
when the product is moved.
The product must be placed in a dry place and covered
securely, in order to secure that moist, metal parts or
other substances do not damage the product.
It is not allowed to place anything on top of the product.
5.0 Assembly, installation and start of
operation
5.1 Location
To ensure a flawless function, the product must be in-
stalled indoors in e.g. an engineering room with sound
ventilation.
Outdoor installation is not recommended, and a canopy
must always be used as a minimum if indoor installation
is not possible.
We do not recommend outdoor installation, as the risk
of water and condensation in the product increases, and
the electronic components do not function at temperatu-
res below 5°C.
Before installing the product, ensure that an optimal lo-
cation is chosen. Is there enough space for the product?
Is there space for maintenance and filter changes?
Place the product on a level and stable base (e.g. a con-
crete concrete floor) and secure it.
Avoid as far as possible bends immediately before the
inlet and after the outlet, as this could reduce the perfor-
mance of the product.
5.2 Installation
The following installation should only be carried out by a
trained installer.
5.2.1 Installation
Procedure:
1. Place the HVU on a solid foundation (e.g. a concrete
floor) where there is no possibility for vibrations to be
transmitted. In addition, allowance shall be made for
filter changes (i.e. minimum headroom of 800 mm).
2. The piping is connected to the HVU. On the inlet side
the pipe can be fixed e.g. by means of a snap lock
system.
Remember to seal the joint with sealant and/or tape!
3. To ensure free mixing, the discharge should be di-
rected two meters above the roof ridge towards the
atmosphere with a discharge velocity of at least 8 m/s.
4. The entire system/piping should always be thorough-
ly inspected for leaks. Leaks must be sealed. The sy-
stem must not be used for the following 24 hours.
