Use
4.1
First start up
Only start up the drier once you have thoroughly tested all the hydraulic, refrigeration and electrical
connections.
1.
Close the isolating valves on the drier and open the by-pass valve.
2.
Check that the master switch is set to O.
3.
Start the air compressor
4.
Set the master switch to I. The drier digital display panel comes ON.
5.
The refrigerating compressor and the fan start after a 2 minute safety time-out.
6.
Pressurise the drier by slowly opening the inlet valve.
7.
Slowly open the drier exhaust valve and then close the by-pass.
8.
The drier will operate until the digital display panel indicates
00
°C (
32
°F).
9.
The drier will then stop for at least 2 minutes and will only start again when the digital display panel
indicates
04
°C (or 39°F).
If the compressed air flow oscillates, it is normal for these values to be exceeded temporarily.
10.
Check that the purge opens when the TEST button is pressed.
11.
Check that the solenoid valve opens automatically every 5 minutes.
The drier is now ready to run normally.
4.2
Normal Start up
The following key points will optimise daily use:
•
Always turn your drier ON 5 to 10 minutes before the air compressor. In this way, your compressed air will be
treated from the first m3.
•
Your appliance can remain ON even if compressed air production is stopped. Its electronic regulation will
automatically start and stop it to meet demand. You only need to turn off your drier at night, at the
weekend or when you go on holiday!
•
The standard drier parameters programmed in our factory meet 90% of all applications. If the conditions in
your plant are standard (i.e. not a very hot environment, no partial drying upstream, no voluntary increase
in the dew point...), do not spend time on modifying these parameters.
