EN WARNING! Risk of personal injury
• Use suitable protective equipment: goggles,
ear protection and a protective mask.
• A high vacuum system creates a powerful
suction that may cause serious eye injury or
hearing impairment. Persons who will be us-
ing FlexPAK 800/1000 DX, or may come in
contact with FlexPAK 800/1000 DX, are to
be informed about this risk.
• Never look into the exhaust air duct. Debris
and particles coming out of the outlet may
cause eye injury.
• Use proper protective equipment when risk-
ing exposure to dust.
• Never operate the unit without a plastic sack
in the dust bin if the dust is hazardous.
• The outlet silencer and fan may reach high
temperatures during normal operation.
CAUTION! Risk of equipment damage
Read and follow all instructions in the Installa-
tion and Service Manual before use.
Some materials may undergo chemical reac-
tions in combination with humidity/water.
Such humidity may, for example, form if the
humidity in the extracted air is condensed in
the filter.
5.1 Before initial start-up
The unit is NOT to be operated under any cir-
cumstances without directing the exhaust air
away from the unit.
It is important that no dust, objects or debris are al-
lowed to fall down into either the inlet or outlet of the
side channel fan.
The unit with its accessories are tested before deliv-
ery, and all functions are checked. Before the initial
start-up ensures the following:
• The maintenance switch has been installed, see
ure 9 item 8.
• The room where the unit is located, if small, has ad-
equate ventilation. See the Installation and Service
Manual.
• The ducting is connected to the dust collector inlet.
• An exhaust air duct is attached to the outlet to dir-
ect hot exhaust air away from the unit.
• The compressed air supply is permanently connec-
ted. Idle mode and the filter cleaning will not work
properly without a compressed air supply.
• The PS cable is connected, but no valves at works-
ites are open.
• Make sure that the ground check measurement has
been performed. See the Installation and Service
Manual.

5.2 Initial start-up
WARNING! Risk of electric shock
• Unauthorized personnel may NOT remain in
the vicinity of the unit when the control unit
is open. Authorized personnel performing
inspections and adjustments on the control
equipment need to be careful to avoid elec-
trical shocks.
• Always disconnect the supply voltage using
the maintenance switch when performing in-
spections and adjustments. If the frequency
converter has to be opened, wait 5 minutes
after disconnecting power to avoid a static
electric shock.
Ensure that no valves at any workstations are
open.
• Remove the control unit lid since checks and adjust-
ments in the control unit may be necessary during
the initial start-up. (The PLC and the software are
password-protected).
The initial start-up is to be performed with the acous-
tic enclosure removed to verify the direction of ro-
tation. Refit the acoustic enclosure when all checks
have been performed.
5.2.1 Check the filter cleaning function
• When the unit is in Running mode, see
tion 6.1.3 Running (Running
cleaning button, see
the filter cleaning procedure starts.
The filter cleaning function consists of the Filter
Cleaning Valve (FCV), which is a pneumatic cylinder
with a valve disc. The FCV is located at the top of the
filter housing under the enclosure, see
6.
A distinct change in sound can be heard as the valve
releases atmospheric air into the filter, indicat-
ing that the function works properly. See also
tion 3.1 Function'.

tings are used.
• Press the Standby/Running button to put the unit
into Standby mode.
The unit is not to start until a valve is opened at a
workplace activating its microswitch, or the test start/
filter cleaning button is pressed, see the top of
ure 8 and Section 8.3 Filter cleaning in Running
When the valve closes, the unit switches over to Idling
