• 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 closed
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.
• Turn on the main switch - pos. 1 on the control panel.
• Check that the mains detection light of the ON/OFF
button - pos. 4 of the control panel - is ON.
• Wait at least two hours before starting the dryer
(compressor crankcase heater must heat the oil of the
compressor) - only models RA 180-720.
• Ensure the cooling water flow and temperature is
adequate (Water-Cooled).
• Switch ON the dryer pressing the button "I - ON" of the
ON/OFF switch - pos. 4 of the control panel.
• Ensure that DMC14 electronic instrument is ON.
• Ensure the consumption matches with the values of the
data plate.
• Check that the rotation direction of the fan
corresponds with the arrows on the condenser (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.
