Before using your vacuum pump . . .

Note about Motor Voltage Connections:

In all cases, motors are designed for operating voltages plus or minus 10%

of the normal rating (see Pump Specications). Single voltage motors are

supplied fully connected and ready to operate.

1. Conrm that the voltage and frequency at the outlet match the

specications on the pump motor decal.

2. Conrm the ON-OFF switch is in the OFF position before you plug the

pump into an outlet.

3. Remove and discard the exhaust plug from the exhaust tting.

The pump is shipped without oil in the reservoir. Before starting the

pump, ll it with oil. Remove the OIL FILL cap (red plastic plug at the

front of the handle), and add oil until oil appears in the bottom of the sight

glass. For oil capacities, refer to Pump Specications in this manual.

5. Replace the OIL FILL cap, and remove the cap from one of the inlet

ports.

6. Turn the motor switch to ON.

7. When the pump runs smoothly, replace the cap on the inlet port. This

may take from two to 30 seconds, depending on the ambient temperature.

8. After the pump has run for approximately one minute, check the sight

glass for the correct oil level — oil should be even with the sight glass

OIL LEVEL line. With the pump off, add oil if necessary.

Note: When the pump is running, the oil level should be even with the

line on the sight glass. Underlling the pump will result in poor vacuum

performance; overlling can result in oil blowing from the exhaust.

Your pump is now ready to evacuate air conditioning and refrigeration

systems. Follow normal service procedures and the A/C-R

manufacturer’s instructions for connections to the system.

CAUTION: Before connecting your vacuum pump to an A/C-R system, remove

refrigerant from the system in an accepted manner. Damage to the

pump may occur if evacuation is started while the system is under

high pressure. Robinair recommends the use of its Refrigerant

Recovery and Recycling equipment.
