5.3.2 External positioning
A solid base on which to position the unit must be created.
This base must be perfectly flat and horizontal. Its dimensions must be adequate for those of the unit.
The slab must be:
- made in a suitable foundation about 15-20 cm higher than the surrounding ground;
-
flat, horizontal and able to bear at least 4 times the operating weight of the unit;
- at least 30 cm longer and wider than the unit.
Although the units transmit low levels of vibration to the ground, it is advisable to lay a strip of hard rubber between
the base frame and the support surface.
If better isolation is required, it is advisable to use the anti-vibration mounts available as accessory.
The units should not be positioned near private offices, bedrooms or areas where low sound emissions are required.
It is also advisable not to install the units in narrow passages or small spaces, in order to avoid reverberations,
reflections, resonances and acoustic interactions with elements outside the unit.
To avoid the risk of corrosion, do not install the units in an environment where there is an aggressive chemical
atmosphere.
Particular attention should be given to atmospheres containing sodium chloride.
5.3.3 Anti-vibration mounts
In order to reduce vibrations transmitted to the structure, it is advisable to install the unit on rubber anti-vibration
mounts, available as an option and to be requested when placing the order.
The dimensional diagram with footprint shows the position and load of each anti-vibration mount.
The anti-vibration mounts must be fixed on before positioning the unit on the ground.
To install the anti-vibration mounts, see the instructions attached to the optional extra.
When fixing the anti-vibration mounts, the unit should be lifted off the ground by no more than 200 mm
and no parts of the body should be placed under the unit.
5.3.3.1 Rubber anti-vibration mounts
The anti-vibration mount consists of an upper metal bell in which there is a screw for fixing it to the base of the unit.
The anti-vibration mount is fixed to the base through the two holes on the flange. The flange of the anti-vibration
mount bears a number that identifies the hardness of the rubber support.
