Storage
Storage of compressors
The compressor should be stored in a dry and,
where possible, heated room. This applies particu-
larly during the winter months.
NOTICE
Material damage
Material damage through exceeding of the per-
missible temperature range
➯
Where there is a risk that the permissible
temperature limits of +2 ...+65 °C / +36 ...
+149 °F could be over or undershot, contact
Gardner Denver.
Corrosion protection
Before they leave the factory all compressors are
protected against corrosion during transport and
short term storage before commissioning. If com-
pressors are stored for longer than 6 months, ad-
ditional precautions must be undertaken.
Also compressors that have been taken out of ser-
vice for a long period, must be protected against
corrosion.
4.3
Positioning
Requirements for the installation location
The entire surface of the compressor must be
placed on a sufficiently load bearing substrate.
The bearing surface must be level to within 3 mm /
0.12 ".
The installation location (compressor room) must
be dimensioned such that a clearance of 1 m /
39 " on side “A” and 1.5 m / 59 " on side “B” is not
exceeded. The clearance above the compressor
should be at least 1.50 m / 59 ". Moreover, ade-
quate access must be provided for maintenance.
Fig. 4-2: Positioning / clearances
Position the compressor so that it is sufficiently
accessible and the required cooling is ensured.
Do not block the air inlet.
Avoid moisture.
Ventilation
DANGER
Risk of suffocation
Risk of suffocation due to inadequate
ventilation
➯
The operator must provide adequate
ventilation of the compressor room.
To be able to dissipate the heat generated during
operation, the compressor room must be of suffi-
cient size and have adequate ventilation.
The recommended minimum size of the compres-
sor room is 60 m
3
/ 646 ft³.
The air inlet and outlet openings should have
a minimum cross section of 1.8 m
2
/ 19 sq. ft
(air-cooled compressor) ; x.xx m
2
/ xx sq. ft (wa-
ter-cooled compressor).
The intake air opening should be positioned as low
as possible. The extract air opening should be po-
sitioned as high as possible.
Provide the air openings with sieves to prevent
penetration of dirt into the compressor room.
The design of the ventilation facility is primarily
based on the required cooling air flow. See "Tech-
nical data”.)
