The blower set must be stored in its original packaging in a 
dry place and must be protected against dust. Compact 
units in the acoustic enclosure intended for outside use can 
be stored in the open air. If the blower set has been stored 
for more than six months, you should (re)preserve it. For 
this purpose, you can use standard preservative agents. 
Storage conditions: 
Temperature: -30 °C up to 40 °C 
Relative humidity: up to 80%

NSTALLATION AND ASSEMBLY
Assembly in the Open Air 
To install the blower set (the set including the enclosure) in 
the open air, you must consider the local conditions (snow, 
possibility of flooding, etc.) 
 
Service passages and the space necessary for the set 
assembly in the machine hall are shown in Appendix 3. 
Acoustic enclosures designed for outside use also serve as 
weather protection. 
 
Assembly in the machine hall 
The minimum dimensions of the machine hall are based on 
the maximum dimensions of the compact unit (acoustic 
enclosure) and the necessary 1-metre (better 1.2-metre) 
operation space at the sides of the blowers (enclosures) and 
between the blowers (enclosures). They are further based 
on the 1.2-metre space between the wall of the discharge 
section at the acoustic enclosure and the wall. The machine 
hall height depends on the method chosen for handling the 
machine(s). 
 
When designing the machine hall, you must remember the 
openings for the blower sets (the delivered sets are 
normally assembled). The acoustic enclosure are 
demountable. You should consider equipping the machine 
hall with an overhead track for a crane crab or leaving 
enough space for a forklift truck in order to handle those 
blower sets to be maintained or repaired (necessity to 
dismantle the blower and/or motor if a failure has 
occurred). 
The space necessary for installation of individual types of 
SHARK blower sets can be derived from the dimensions 
stated in the dimensional drawings. 
 
The floor designed for installation must be flat and 
dimensioned for the machine weight and anchor length. 
With respect to the loading capacity, no special 
requirements are stipulated for the floor design since both 
the blowers and motors are dynamically balanced. The 
mechanical oscillation power of the blowers and motors are 
stated in Tables 3 and 4. The weight of the blower set is 
distributed between its individual bases. The weight of the 
delivered blower set is stated in its appropriate dimensional 
drawing. 
The blower set must be positioned horizontally by placing 
plates under the machine bases. The permitted deviation is 
1 mm for 1 metre. 
 
WARNING
After being set in its position, the blower set must 
be anchored to the floor. Otherwise, it could move 
spontaneously and thus be damaged. 
 
Working procedure for anchoring compact units and 
acoustic enclosures. 
1. Drill a hole and clean it; 
2. Stick the anchor into the hole; and 
3. Tighten the nut.

The space and diameters of the base holes are stated in the 
enclosed dimensional drawing of the compact unit. The 
procedure for anchoring acoustic enclosures is the same. 
You should, however, pay attention to the tightness of the 
gap between the hood and the floor. After setting the hoods 
in their positions, you must also level any floor unevenness 
in order to prevent the sidewalls from being tight. In order 
to seal the gap between the hood and the floor, you can 
apply polyurethane foam, for example. The electric cable 
must be laid in the floor. 
If you intend to put a blower set in the hood on a half grid, 
you must order a non-standard enclosure because the 
bottoms of the acoustic enclosures are not soundproof. 
 
Connecting the pipeline to the SHARK compact unit 
Since the entire aggregate is placed on rubber dampers, the 
pipeline must be connected through flexible elements. 
Otherwise, the running blower could shake the pipeline, 
thus increasing the noise level. Standard compact units are 
delivered with compensators for connection of the 
discharge section. If a SHARK blower for vacuum is been 
required or intended to be connected to the central suction, 
a compensator for connection of suction is also supplied. 
Delivered compensators and valves of larger blower sets 
supplied with acoustic enclosures (from the K 302 type) are 
not installed. These parts must be installed behind the 
outlet flange of the discharge silencer or also in front of the 
inlet flange of the suction silencer according to the 
following pictures:
