Control Box Features And Operation - Vmac VR70 Owner's Manual

3. Allow the vehicle to run for an additional 15 minutes after
reaching operating temperature to allow radiant heat transfer
throughout the compressor system. If the vehicle is to be used
consistently in cold climates the use of a de-icer kit (VMAC part
#A700031) is recommended.
4. Activate the compressor by pressing the "ON" button.
The clutch will engage, a green light will be displayed on the control
box and the engine speed will increase to the Maximum Rpm setting
on the throttle, once the system has reached full regulated pressure,
the engine should drop down to VR idle – a base preset idle RPM.
