2.2 Installation proposals (Figs. 2.5 and 2.8)

Ref. Description
1. Install the compressor on a level floor suitable for taking the weight of the compressor.
Recommended minimum distance between the top of the bodywork and the ceiling: 1200
mm.
2. Remove the plastic plug (if provided) from the compressor air outlet pipe and install an air
outlet valve. Close the valve and connect it to the air net.
3. The pressure drop over the delivery pipe can be calculated as follows:
dp = (L x 450 x Qc1.85) / (d5 x P)
dp = pressure drop (recommended maximum = 0.1 bar)
L = length of delivery pipe in m
d = inner diameter of the delivery pipe in mm
P = absolute pressure at the compressor outlet in bar(a)
Qc = free air delivery of the compressor in l/s
The connection of the compressor air delivery pipe should be made on top of the main air
net pipe to minimize carry-over of possible remainder of condensate.
4. The inlet grids and ventilation fan should be installed in such a way that any recirculation of
cooling air to the compressor is avoided. The air velocity to the grids should be limited to 5
m/s. The required ventilation capacity (per compressor installed) to limit the compressor
room temperature can be calculated as follows:
For ZR compressors:
Qv =0.1 N / dT
