Before using your vacuum pump . . .
Motor Voltage Connections:
Motors are designed for operating voltages ± 10% of the normal rating (see Pump
Specifications). Single voltage motors are supplied fully connected and ready to operate.
1. Confirm the voltage and frequency at the outlet match the specifications on
the pump motor decal.
2. Confirm the ON-OFF switch is in the OFF position before you plug the
pump into an outlet.
3. The pump is shipped without oil in the reservoir. Before starting the pump,
fill it with oil.
a. 15115: Remove the exhaust FittiNg, and add oil until oil appears
in the bottom of the sight glass. For oil capacities, refer to Pump
Specifications in this manual. Replace the exhaust FittiNg.
b. 15310 and 15510: 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 Specifications in this
manual. Replace the OiL FiLL cap.
4. Remove the cap from one of the inlet ports.
5. turn the motor switch to ON.
6. 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.
7. 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. Underfilling the pump will result in poor vacuum
performance; overfilling can result in oil blowing from the exhaust.
the pump is ready to evacuate air conditioning and refrigeration systems. Follow normal
service procedures and A/C-R manufacturer’s instructions for connections to the system.
CautION: Before connecting the 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.
