In the event of unfavourable local conditions, in-
stall air ducts in which the flow velocity of the cool-
ing air must not exceed 5 m/s / 16.5 ft/sec. We
recommend a minimum channel cross section of
1.8 m
2
/ 19 sq ft (air-cooled compressor).
NOTE
To ensure effective heat removal, the installed
auxiliary fans must be dimensioned such that
their air flow is 15 to 20% greater that the cool-
ing air flow required by the compressor.
If installing several compressors in one com-
pressor room, then this applies to the total of the
cooling air flows required by all the compressors
present in the compressor room.
The following figure shows the recommended ven-
tilation requirements.

Positioning the compressor
DANGER
Risk of injury
Danger due to incorrect positioning
➯
Consider the permissible bearing
force of the substrate.
➯
Ensure there is a hard and even
substrate.
➯
The entire surface of the compres-
sor must be placed on an even suit-
able substrate.
➯
The compressor must not be oper-
ated on the transport pallet.
➯
No inflammable or explosive mate-
rials may be stored in the vicinity of
the compressor.
1. Set down the compressor at the destination
point.
2. Ensure that the support surface is level to
within 3 mm / 0.12 ". (The compressor does not
have any levelling means fitted on it.)
