3.2 FIRST START-UP
This procedure should be followed on first start-up, after periods of extended shutdown or
following maintenance procedures.
Qualified personnel must perform the start-up.
Sequence of operations (refer to paragraph 5.1 Control Panel) :
•
Ensure that all the steps of the “Installation” chapter have been observed.
•
Ensure that the connection to the compressed air system is correct and that the piping is suitably fixed
and supported.
•
Ensure that the condensate drain pipe is properly fastened and connected to a collection system or
container.
•
Ensure that the by-pass system (if installed) is open and the dryer is isolated
•
Ensure that the manual valve of the condensate drain circuit is open.
•
Remove any packaging and other material which could obstruct the area around the dryer.
• Activate the mains switch.
• Switch on the dryer by closing the main switch on the control panel (pos. 1).
• Ensure that DMC14 electronic instrument is ON.
• Ensure the consumption matches with the values of the data plate.
•
Ensure the fan work properly - wait for its first interventions.
• Allow the dryer temperature to stabilise at the pre-set value.
• Slowly open the air inlet valve.
• Slowly open the air outlet valve.
• Slowly close the central by-pass valve of the system (if installed).
•
Check the piping for air leakage.
•
Ensure the drain is regularly cycling - wait for its first interventions.
3.3 START-UP AND SHUT DOWN
Start-up (refer to paragraph 5.1 Control Panel) :
• Check the condenser for cleanliness.
• Verify that the system is powered.
• Switch on the dryer by closing the main switch on the control panel (pos. 1).
•
Ensure that DMC14 electronic instrument is ON.
•
Wait a few minutes; verify that the DewPoint temperature displayed on electronic instrument DMC14 is
correct and that the condensate is regularly drained.
•
Switch on the air compressor.
Shut down (refer to paragraph 5.1 Control Panel) :
•
Verify that the DewPoint temperature displayed on electronic controller DMC14 is correct.
•
Shut down the air compressor.
•
After a few minutes, Shut down the dryer using the main switch on the control panel (pos. 1).
NOTE : A DewPoint within 32°F (0°C) and +60°F (15°C) displayed on DMC14 is correct according to the
possible working conditions (flow-rate, temperature of the incoming air, ambient temperature, etc.).
During the operation, the refrigerating compressor will run continuously. The dryer must remain on during
the full usage period of the compressed air, even if the air compressor works intermittently.
The number of starts must be no more than 6 per hour. The dryer must stop running for at
least 5 minutes before being started up again.
The user is responsible for compliance with these rules. Frequent starts may cause
irreparable damage.
