outlet valve, pressure gauge, pressure relief valve, air pressure switch with an on/off button (MDR), and
condensate drain valve.
• Tank-mounted CR with gas engine: The compressor on an air receiver with air outlet valve, pressure

have two outlet connections:

2.2 Hour meter option
The hour meter is triggered by the motor’s magnetic field, so the hours display actual operation. When the
motor is on, the hours icon will blink on/off indicating the hour meter is active.
With solid-state technology the hour meter is built with a custom chip and with solid construction for
maximum durability for harsh environments and rugged applications.
