1.
Problems with pneumatic control at low temperatures.
Damage to the machine may be caused by ice particles in the pneumatic control and feedback
systems.
➤ Let the machine warm up in IDLE to ensure trouble-free regulation.
2. Allow the machine to warm up in idle with open air outlet valves until an airend discharge tem‐
perature of 86°F is reached. The airend discharge temperature is shown at the remote ther‐
mometer contact on the instrument panel.
