Robinair High Performance Vacuum Pumps
Congratulations on purchasing one of Robinair’s top quality vacuum
and refrigeration service, and is built with Robinair’s proven offset rotary vane for fast, thorough evacuation.
You’ll appreciate these key features...
Iso-ValveTM Allows the pump to be shut off while still connected to the A/C-R
system, which is handy for checking rate of rise. With the valve handle in the OPEN position, the pump is open to the system being evacuated. In the CLOSED position, the pump is isolated from the system.

Pump Components
Wear safety goggles when working with refrigerants. Contact with refrigerants may cause eye injury.
Incorrect use or electrical connections may cause electrical shock. Read and follow instructions carefully, and take precautions to avoid electrical shock hazards. All associated devices must be correctly grounded before energizing circuits.
Normal operating temperatures will cause certain external portions of the pump to be hot to the touch. Do not touch the pump housing or motor during operation.

In all cases, motors are designed for operating voltages, plus or minus 10% of the normal rating (see SPECIFICATIONS). Single voltage motors are supplied fully connected and ready to operate.

Verify the voltage and frequency at the outlet match the specications on the

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

remove refrigerant from the system in an accepted manner using an approved recovery unit. Damage to the pump may occur if evacuation is started while the system is under high pressure.

To use the gas ballast feature...
Moisture from the A/C-R system that is carried into the pump as a vapor
tends to condense into a liquid and combine with the vacuum pump oil. When moisture contaminates the pump oil, it reduces the pump’s ability to reach its ultimate deep vacuum level.
The gas ballast valve purges a small amount of atmospheric air through
the exhaust chamber. This extra volume of air mixes with the vapor from the refrigerant system to prevent condensation and to help exhaust moisture in the form of vapor from the pump.
The gas ballast valve is located beside the handle, opposite the inlet
tting. To use the gas ballast, start the pump and open the gas ballast
valve until the system has reached 1000–3000 microns. Close the valve to allow the pump to pull down to its ultimate vacuum level.
The gas ballast valve may be opened or closed at any time during pump
operation. It is fully open at two turns counterclockwise.
Note: Robinair recommends the use of a thermistor vacuum gauge to
most accurately measure vacuum levels.
To shut down the pump after use...
To prolong pump life and promote easy starting, follow these procedures
for shutdown:
1. Close the manifold valve between the pump and the system.
2. Turn the Iso-Valve™ to the CLOSED position.
3. Remove the hose from the pump inlet.
4. Turn the pump power switch to OFF. Return the Iso-Valve™ to the OPEN position for a few seconds to relieve any vacuum inside the pump.
5. Cap the inlet port to prevent any contamination or loose particles from entering the port.

To maintain the high vacuum pump...
For maximum performance, Robinair recommends changing vacuum

residual oil.
4. Replace the OIL DRAIN cap. Remove the OIL FILL cap, and ll the
reservoir with new vacuum pump oil until the oil just shows at the bottom of the sight glass. The approximate oil capacity of the pump is 15 ounces.
5. Verify the inlet ports are capped, and turn ON the pump. Allow it to run for one minute, and check the oil level. If the oil is below the sight glass OIL LEVEL line, add oil slowly (with the pump running) until the oil reaches the OIL LEVEL line. Replace the OIL FILL cap, making sure the inlet is capped and the drain cap is tight.
6. a) If the oil is badly contaminated with the sludge that forms when
water is allowed to collect in the oil, you may need to remove the oil reservoir cover and wipe it out.

b) Another method of dealing with heavily contaminated oil is to force
the oil from the pump reservoir. To do this, allow the pump to run until it is warmed up. While the pump is still running, remove the oil drain cap. Slightly restrict the exhaust. This will back-pressure the oil reservoir and force the oil from it, carrying more contaminants. When
the oil ceases to ow, turn off the pump.
Repeat this procedure as required until the contamination is removed.
Replace the OIL DRAIN cap, and rell the reservoir to the correct level
with fresh pump oil (see Step 4).

Troubleshooting Guide
This Robinair pump has been designed for dependable use and long life.
If something should go wrong, however, the following guide will help you get the pump back into service as quickly as possible.
If disassembly of the pump is required, please check your warranty. The
warranty may be voided by misuse or customer tampering that results in the pump being inoperable.
Check line voltage. Robinair pumps are designed to start at +10% line

leak-free. Conrm leakage by monitoring the vacuum with a thermistor
gauge while applying vacuum pump oil at connections or suspected leak
points. Vacuum will improve briey while the oil is sealing the leak.
3. Verify the pump oil is clean. A badly contaminated pump may require several oil ushes. See OIL CHANGE PROCEDURE.
Note: Use only high vacuum pump oil such as Robinair’s Premium High
Vacuum Pump Oil. Other oils will prevent pull-down to a deep vacuum.
4. Verify the gas ballast knob is tightly closed.
5. Verify the oil is at the correct level. For maximum pump operation, the oil must be even with the OIL LEVEL line on the sight glass when the pump is running. See OIL CHANGE PROCEDURE. Do not overll — operating temperatures will cause the oil to expand so it will appear at a higher level than when the pump is not running. To check the oil level, start the pump with the inlet capped. Check the oil level in the sight glass. Add oil if necessary.
If these procedures do not correct the problem,
When You Need Help
contact your nearest Robinair distributor. The distributor may recommend an additional replacement part (this manual contains a replacement parts list) or suggest you send your pump to the nearest authorized service center. Call Robinair’s toll-free Service Line for further information: You may also visit our website at www.robinair.com for technical support.

which fails to operate correctly, should be returned to the distributor or an authorized Robinair service center with a complete, written explanation of the problem. Before returning an out-of-warranty pump, review maintenance procedures to avoid an unnecessary return. Note that contaminated oil or an incorrect oil level will adversely affect pump performance. Replacement parts are available for doing your own service; however, this should be considered only in out-of-warranty situations.
