Installation
5.3 Connection of pipes
NOTICE
Material damage resulting from too high forces and torques of the pipes acting
on the unit!
If forces and torques during installation and operation are too high, the machine can
be damaged.
Ø
Only screw in pipes by hand.
Ø
If necessary, use flexible connections.
CAUTION
Risk of injury due to closed exhaust air opening!
Closed, restricted or covered exhaust air openings can cause too high back pressure
in the machine.
Ø
Never close or restrict the exhaust air openings.
Ø
Keep the permissible back pressures on the drain side:
S-VSI 7.5 kW < + 0.2 bar
S-VSI 5.5 kW < + 30 mbar
Ø
Prevent liquids from accumulating in the exhaust line.
a) Remove the blind plug from the vacuum connection.
b) Connect the pipes with the vacuum connection (Fig. 2/A, 3/A).
c) The exhausted air can be blown out through the exhaust air outlet (Fig. 2/B, 3/B) on the exhaust silencer
or conducted away using a hose or pipe.
To avoid distorting in the piping system, we recommend using compensators.
d) Check that the maximum back pressure is not exceeded!
The suction capacity of the vacuum pump is reduced if the inlet pipe is too narrow and/or too
long.
5.4 Connect cooling water
NOTICE
Property damage due to missing cooling water control!
If there is no cooling water control, the machine can be damaged in case of malfunc-
tion or failure of cooling of the machine when the malfunction is not remedied imme-
diately.
Ø
Pump is only allowed to be operated with cooling water control.
NOTICE
Property damage due to the failing pump!
If the cooling water flow is reduced or interrupted, the cooling of the machine can-
not be ensured. This can cause the blackout failure of the machine and damage the
machine.
Ø
Make sure that the cooling water flow is not interrupted.
