DC 11-Module 7.5 kW - 24 Part No 94141
2008-08-11
Installation
Test running
Th e unit is normally adjusted to a nominal pressure.
Th e pressure can be changed by adjusting the vacuum
relief valve. Please note that it cannot be exceed the
max pressure for the unit. For the 7.5 kW DC 11-Mo-
dule the pressure can be adjusted over the stated max
pressure 19 kPa, up to 23 kPa, under the condition
that the highest rpm, level 3 (70 Hz) is blocked.
1. Verify that the power is isolated or pull out the 5
pin Euro connection.
2. Check that no persons can be injured if the pump
starts and that all outlets are closed.
3. Connect a manometer for the negative pressure
calibrated to –50 kPa to the suction side as close
to the pump as possible.
4. Power up the pump and listen carefully for the
following sounds: A high-pitched whine is normal
from the impeller blades. As the pump draws
cooling air through the vacuum relief valve a
weak hissing should be heard. Check the rotation
direction of the pump.
5. Measure the pressure. Compare with the dimension
point. Th e pressure can be adjusted by adjustment
of the vacuum relief valve, see page 27.
Connection points
1. Compressed air feed 4 l/s, 4 bar (for use with au-
tomatic fi lter cleaning).
2. Electric feed (for use with integrated control
box).
3. Connection point for micro switch circuit(where
existing).
4. Connection of motor tension from a separate con-
trol box (in some cases).
5. Inlet to cyclone (can be rotated for preferred direc-
tion).
6. Exhaust/silencer. (Can be specifi ed as a diff user from
under the unit top.)
7. Holes for fi tting the unit to the ground (where
existing)
Th e unit can be mounted on concrete surface/fl oor of
suitable thickness.
The electrical connection should be connected to
adequate starting equipment. A certifi ed electrician
should make the installation. 5 pin Euro connection
is available as an alternative.
Th e equipment is prepared to draw 3-phase electric feed
and low volt cabling into its enclosure.
Electric cables should be mounted to make it possible
to raise the unit 200 mm for potential bearing changes;
without that the electrical connection would need to
be disconnected.
A separate, lockable disconnect must be installed where
it is readily accessible to the pump. Connect the pipe
work to the inlet and also to the outlet if the machine
has an external outlet. Never start the pump without
the correct cables and hoses being connected. Th
e
outlet can be equipped with a silencer for lowering
the outlet sound. If the outlet is directed up it should
be connected with a bend or a fl ap so rainwater and
objects do not fall into the outlet. Exhaust air can be
between 100-150o C.
Put the plastic bag under the cyclone or connect the
container.
