The gauges on the NR7 are filled with glycol, which reduces flutter. Its operation is managed by a single dial, which can close the machine, recover refrigerant at multiple speeds, and purge the machine all in one. The NR7 also has a condenser coil with multiple rows, which cools the refrigerant during recovery, and it has great airflow to move the most refrigerant possible.

Recommended accessories include a charging scale, large hoses, and the Rapid-Y connection fitting, which allows you to connect two 3/8″ ports into a single 1/4″ port. NAVAC also has a four-port hose holder (FHH4) that has multiple connection points to keep your hoses from getting contaminated between uses. Note that NAVAC hoses are for vacuum and recovery, not charging, so they don’t come with core depressors at either end (but they do come with extra O rings!).

You can connect the accessories by attaching the hoses to the Rapid-Y and the 3/8″ ports and attaching the Rapid-Y to the recovery machine at the 1/4″ port. The hoses need to be connected to the system with a core removal tool. For best results, connect one hose to the liquid line service port and the other to the suction line service port. Then, connect a hose from the recovery machine to the recovery tank.

Once your hoses are connected, start your machine and slowly throttle the flow into the tank via the control knob or dial. When you’ve finished, purge your machine.
