following maintenance procedures.
Qualified personnel must perform the start-up.
Sequence of operations (refer to paragraph 5.1 Control Panel) :
DMC14 Electronic Instrument DMC20 Electronic Instrument
• 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.

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).
• Ensure the cooling water flow and temperature is
adequate (Water-Cooled).
• Switch ON the dryer button "I - ON" of the
ON/OFF switch - pos. 4 on 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.
• 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 "crankcase oil heater" and "Stand-by"
leds on DMC20 are ON.
• Wait at least two hours before starting the dryer
(compressor crankcase heater must heat the oil of
the compressor).
• Ensure the cooling water flow and temperature is
adequate (Water-Cooled).
• Switch ON the dryer keeping the “Dryer Start-up”
button on DMC20 pressed for at least 2 seconds.
• Check that “compressor ON” led on DMC20 is ON.
