Step Action
1 Install the compressor on a solid, level floor suitable for taking the weight.
The recommended minimum distance between the top of the unit and the ceiling is 1.5 m (58.5 in).
The minimum distance between the wall and the back of the compressor must be 200 mm (7.8 in).
Floor-mounted versions must be installed with suitable air receiver.
The pipes between a floor-mounted compressor and air receiver are hot.
2 Position of the compressed air outlet valve.
Close the valve.
Connect the air net to the valve.
3 The pressure drop over the air delivery pipe can be calculated as follows:
Δp = (L x 450 x Q
c
1.85
) / (d
5
x P), with
d = Inner diameter of the pipe in mm
Δp = Pressure drop in bar (recommended maximum: 0.1 bar (1.5 psi))
L = Length of the pipe in m
P = Absolute pressure at the compressor outlet in bar
Q
c
= Free air delivery of the compressor in l/s
4 Ventilation: the inlet grids and ventilation fan should be installed in such a way that any recirculation
of cooling air to the compressor or dryer is avoided.
5 Lay out the condensate drain flexible from timer drain (T) as well as the flexible from condensate
drain valve (4) towards a drain collector. The drain pipes to the drain collector must not dip into the
water of the drain collector. See the
Starting section for the location of the components.
