5.3.2 External positioning

A solid base on which to position the unit must be created.

Thisbasemustbeperfectlyat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;

- at,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o󰀩ces,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,

reections,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xedonbeforepositioningtheunitontheground.

To install the anti-vibration mounts, see the instructions attached to the optional extra.

Whenxingtheanti-vibrationmounts,theunitshouldbeliftedo󰀨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xingittothebaseoftheunit.

Theanti-vibrationmountisxedtothebasethroughthetwoholesontheange.Theangeoftheanti-vibration

mountbearsanumberthatidentiesthehardnessoftherubbersupport.
