Dryer Commissioning
Electrical
1. Carry out earth bonding test per EN60204 and/or local electrical laws and regulations.
2. Check adequate power supply. (Refer to electrical specifications Table on Page 11 .)
3. Voltage at phases must be within 5% of rated voltage.
4. Voltage drop must not exceed 5% when under full load.
5. Check overload settings for each motor circuit.
6. Complete full electrical tests in accordance with EU Directives and local laws, regulations and codes.
Gas Train
1. Pressure test.
• Close inlet valve.
• Close firing valve.
• Fit pressure test nipple into main solenoid inlet flange.
• Attach hand bellows and pressure gauge.
• Pressurise gas train with air to 35 kPa (350 mBar).
• Check for pressure loss at gauge.
• Use leak detection to test for leaks.
2. Set inlet pressure per fuel specifications Table on Page 11 .
3. Set relief valve to open at 550 mBar (55 kPa).
• Apply air pressure via main solenoid inlet flange.
• Increase/decrease spring pressure in relief valve.
• Valve should open at 55 kPa maximum.
4. Set over High Pressure switch to 500 mBar.
5. Set burner high fire pressure.
• Note required high fire pressure from fuel specifications Table on Page 11 .
• Set plenum temperature to approx. 100°C above ambient.
• Light burners.
• Check high-low valve is fully open.
• Read pressure at burner gauge.
• Adjust pressure a regulator to give required pressure.
• Lock regulator.
