5 Start-up
5.1 Preliminary operation
Verify that the operating parameters match with the nominal values stated on the data nameplate
of the dryer (voltage, frequency, air pressure, air temperature, ambient temperature, etc.).
This dryer has been thoroughly tested, packaged and inspected prior to shipment. Nevertheless, the unit
could be damaged during transportation, check the integrity of the dryer during first start-up and monitor
operation during the first hours of operation.
Qualified personnel must perform the first start-up.
When installing and operating this equipment, comply with all National Electrical Code and any
applicable federal, state and local codes.
Who is operating the unit is responsible for the proper and safe operation of the dryer.
Never operate equipment with panels removed.
5.2 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 7.1 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 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.

ACT ES 200-500 3phase - Turn on the main switch - pos. A on the control panel.

ACT ES 200-500 3phase - Wait at least two hours before starting the dryer (compressor crankcase
heater must heat the oil of the compressor).

Turn ON the switch - pos. 1 on the control panel.

Ensure that electronic instrument is ON.

If the temperature displayed on the electronic instrument is sufficiently high, verify that the refrigerating
compressor starts within a few minutes. NOTE! – With low temperatures, the refrigerating compressor
will remain OFF.

Ensure the consumption matches with the values of the data plate.

ACT ES 200-500 3phase - Check the rotation direction of the fan – 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.
