1. Turn on the compressed air supply to the cartridge filter.
Adjust to 0,6 MPa (6 bar, 87 psi) of pressure. Pressure of
0,4 to 0,6 MPa is the most typical setting for satisfactory
cleaning performance.
2. Close the regulating damper halfway,
see figure, page 17.
3. Teststart the fan without any explosive dust load.
Check fan impeller rotation. Refer to the rotation sticker on
the fan motor. Proper fan impeller rotation is extremely
important. Contact a qualified electrician if the impeller
rotation must be reversed.
NB! Follow the start instructions in the Instruction
Manual which comes with Nederman NCF EX fans.
4. Adjust the fan for the proper system airflow that is
desired by adjusting the regulating damper. The air flow
can be measured with a fixed airflow meter (or a pitot tube)
and a micro-manometer.
IMPORTANT! Too much airflow can cause electrical
system failure and dramatically reduce the life of the
filter element.
5. All the solenoid valves should open and close con-
tinuously with a set interval time between each cleaning
pulse (factory set of 30 seconds).
Check operation of the solenoid valves in the following way:
Set the pause time on 1 s (position 0 on S1 in the con-
nection box, see picture). NB! This is only a control setting
and should not be used for normal operation. Start the
system and count the number of air pulses. It should be
6 pulses per module.
NB! Return the pause time to the original value
after checking.
STARTING THE SYSTEM
WARNING!
Risk of personal injury!
Stand clear of blower fan exhaust area as
debris can be exhausted and cause injury.
