Installation; Test Running - Dustcontrol DC 11-Module Betriebsanleitung

Installation

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.)

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

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 100-150 o C.
Put the plastic bag under the cyclone or connect the
container.
