9.13 Electronic drainer (optional)
Instead of the usual drain system (a solenoid valve controlled by means of electronic instrument); an electronic level controlled drainer can
be installed as option. This drainer consists of a condensate accumulator where a capacitive sensor continuously checking liquid level is
placed: as soon as the accumulator is filled, the sensor passes a signal to the electronic control and a diaphragm solenoid valve will open
to discharge the condensate. For a complete condensate discharge the valve opening time will be adjusted exactly for each single drain
operation. No condensate strainers are installed. No adjusting is required. A service valve is installed before the electronic drain in order to
make check and maintenance easily. At dryer start-up verify that this valve is open.

10. OPERATION
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 transpor-
tation, 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.
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 9.1 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.
• Turn ON the switch - position 1 on the control panel.
• Ensure that electronic instrument is ON.
• Ensure the consumption matches with the values of the data plate.
• Ensure the fan works 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.
