At the first start-up, or in case of start-up after a long inactivity period or following to maintenance
operations, follow the instructions given below. The start-up must be performed by qualified
personnel.
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.
• Ensure the cooling water flow and temperature is adequate (Water-Cooled).
• Remove any packaging and other material which could obstruct the area around the dryer.
• Activate the mains switch.
• Turn on the main switch - pos. 1 on the control panel.
• Ensure that electronic controller (DMC15 or DMC14) is ON.
• Ensure the consumption matches with the values of the data plate.
• Ensure the fan works properly - wait for its first interventions (Air-Cooled).
• 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.
Operation (refer to paragraph 5.1 Control Panel) :
• Check the condenser for cleanliness (Air-Cooled).
• Ensure the cooling water flow and temperature is adequate (Water-Cooled).
• Verify that the system is powered.
• Turn on the main switch - pos. 1 on the control panel.
• Ensure that electronic controller (DMC15 or DMC14) is ON.
• Wait a few minutes; verify that the DewPoint temperature displayed on the electronic controller (DMC15
or DMC14) is correct and that the condensate is regularly drained.
• Switch on the air compressor.
Switching OFF (refer to paragraph 5.1 Control Panel) :
• Verify that the DewPoint temperature displayed on the electronic controller (DMC15 or DMC14) is correct.
• Switch OFF the air compressor.
• After a few minutes, switch OFF the main switch - pos. 1 of the control panel of the dryer.
DMC15 Electronic controller
NOTE : A DewPoint included in the green
operating area of the electronic controller is
correct according to the possible working
conditions (flow-rate,
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.

3.3 OPERATION AND SWITCHING OFF
temperature of the
DMC14 Electronic controller
NOTE : A DewPoint within 0°C and +10°C
displayed on the electronic controller is correct
according to the possible working conditions
(flow-rate, temperature of the incoming air,
ambient temperature, etc.).
