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 300 mm (19.5
in).
Floor-mounted versions, if the compressor is not equipped with unloader valve (i.e. G2-4), must
be installed with a suitable air receiver with a minimum capacity of 200 l (60 US gal).
The air receiver should not be bolted to the floor.
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.
The air velocity to the grids must be limited to 5 m/s (200 in/s).
The required ventilation capacity to limit the temperature of the compressor room can be
calculated from the following formula:
Q
v
= 0.92 N / ΔT
Q
v
= Required ventilation capacity in m
3
/s
N = Shaft input of compressor in kW
ΔT = Temperature increase in the compressor room in °C
5 Position of the mains cable entry.
6 Lay out the condensate drain pipe from the dryer automatic drain (D) as well as the pipe from
the manual drain valve underneath the tank (T) towards a drain collector. The drain pipes to the
drain collector must not dip into the water of the drain collector. See section Starting for the
location of the components.
