5.13 Compressed air installation
WARNING! Risk of personal injury
• Use ear protection and safety goggles.
• The compressed air valve is to be locked in
the closed position during maintenance.
5.13.1 Requirements
The specified air consumption of the unit is
limited to the short operation of the cleaning
valve.
Take measures necessary to avoid water or hu-
midity in the compressed air when the unit is
installed in cold environments.
If antifreeze additives are used, use them con-
tinuously. Once added, the removal of the anti-
freeze additive may cause the pneumatic com-
ponents to malfunction.
For air consumption, quality and maximum and minim-
um pressure, see Section 3.3 Technical data .
As new ducts may contain dirt, particles or debris, the
compressed air pipe is to be blown clean before con-
necting the unit. A compressed air filter, see Figure 9 ,
item 7, is to be installed to ensure the reliable and safe
operation of the unit. A compressed air valve, that
vents the remaining pressure of the unit, is to be in-
stalled, see Figure 9 , item 6.
5.13.2 Installation
Secure the compressed air line properly.
Connect a compressed air supply to the inlet, see Fig-
ure 5 , item 20, and Figure 9 , items 6 and 7.
Air pressure hoses are to be fitted together with
electrical cables with straps, alternatively in a com-
mon protective hose. Air pressure hoses are to be
anchored mechanically.
6 Maintenance
Read Chapter 3 Description before carrying out any
maintenance work. Maintenance work means that the
equipment will have to be opened and possibly dis-
mantled. This may constitute a risk and the mainten-
ance personnel need to know about the risks that may
occur when acting incorrectly.
WARNING! Risk of personal injury
• The motor, fan and air duct may become very
hot during operation.
• Always use an approved breathing mask,
goggles and gloves when replacing the dust
sack and other work that involves exposure
to dust.
• Use ear protection when the unit is in opera-
tion and work is carried out in the vicinity of
the upper section of the dust collector.
• Parts may be very heavy. Always use ad-
equate lifting equipment when handling
parts and consumables.
• Always use adequate safety measures when
performing work in an elevated position.
CAUTION! Risk of equipment damage
During maintenance, it may be necessary to re-
move the acoustic enclosure over the motor
while the motor is in operation. Take care to
prevent objects from falling down into the mo-
tor cooling fan.
Always disconnect the supply voltage with
the maintenance switch before any service,
whether mechanical or electrical. Always lock
the maintenance switch in the off position and,
if possible, secure it with a padlock.
Always disconnect the compressed air sup-
ply before any service, whether mechanical or
electrical.
Contact Nederman if the frequency converter
needs service.
The unit is CE-marked. Connections to the unit,
initial start-up and maintenance are to be car-
ried out according to the product manuals.
6.1 Checks one month after installation
and every year
WARNING! Risk of electric shock
Always disconnect the supply voltage with
the maintenance switch before any service,
whether mechanical or electrical. Always lock
the maintenance switch in the off position. Do
not use the emergency stop button as a substi-
tute.
