8. Safety and Control Device Setting
• Compressor Protection
High Pressure Switch: This switch cuts out the
operation of the compressor when the
discharge pressure exceeds the setting.
• Fan Motor Protection
When the thermistor temperature is reached to
the setting, motor output is decreased.
The other way, when the temperature becomes
lower, limitation is cancelled.
