Compressor Pressure Adjustment (Fig. 6)
The compressor pressure is factory set and must be checked and adjusted by qualified
technicians only. Tampering with the unit may be dangerous.
Remove pressure gauge cap. Connect a pressure gauge on the pressure measuring port on the rear
guard. Start heater and read air pressure value. If necessary adjust pressure to the correct value
turning the adjusting screw (the air vent hole in the adjusting screw middle) clockwise to increase,
anticlockwise to decrease the pressure:
