1. Note on Motor Voltage Connections 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 specifications on the pump motor decal Place the ON OFF switch in the OFF position before you plug the pump into an outlet Verify the gas ballast valve is closed Remove and discard the exhaust plug from the end of the pump handle The pump is shipped without oil in the reservoir Before starting the pump fill it with oil Remove the OIL FILL cap plastic plug directly in front of the handle and add oil until oil just shows in the bottom of the sight glass The approximate oil capacity of the pump is 15 ounces Replace the OIL FILL cap and remove the cap from one of the inlet ports OPEN the Iso Valve Turn ON the motor switch When the pump runs smoothly CLOSE the Iso Valve and replace the cap on the inlet port This may take from two to 30 seconds depending on ambient temperature After the pump runs for approximately one minute check the sight glass for the correct oil level the oil should be even with the sight glass OIL LEVEL line Add oil if necessary Note When the pump is running the oil level should be even with the line on the sight glass Underfilling will result in poor vacuum performance overfilling can result in o2. free Service Line for further 800 822 5561 information You may also visit our website at www robinair com for technical support 4 Call Toll Free Warranty Coverage Out of Robinair vacuum pumps are warranted against defects in material and Warranty workmanship for one year of normal use from the date of purchase See your distributor for warranty details A pump that is no longer covered by the one year warranty period and 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 Product however this should be considered only in out of warranty situations Registration Register your vacuum pump at www robinair com Replacement Parts Part Figure 15400 15600 Oil Drain Cap qty 6 1 40572 40572 Oil Drain Kit includes oil drain cap 2 48116 48116 Module Cover Kit includes items 2 4 5 3 15337 15337 Oil Fill Cap includes gas ballast valve 4 15371 15371 Intake Fitting includes intake caps 8 15364 555124 Intake Caps 4 3 s and 2 flare 1 ea 9 555133 555133 Vent Bolt includes o rings 11 15338 15338 Handle Power Cord Switch Assembly 12 1
3. regulations in your jurisdiction Oil can be forced from the pump by opening the inlet and partially blocking the exhaust with a cloth while the pump is running Do not operate the pump for more than 20 seconds using this method When the flow of oil has stopped tilt the pump forward to drain residual oil Replace the OIL DRAIN cap Remove the OIL FILL cap and fill 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 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 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 Cleaning the Pump 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 flow turn off the pump R
4. using a commercial pipe thread sealer Verify the Iso Valve on the pump is in the OPEN position Verify the vacuum gauge and all connections are in good conditon and leak free Confirm leakage by monitoring the vacuum with a thermistor gauge while applying vacuum pump oil at connections or suspected leak points Vacuum will improve briefly while the oil is sealing the leak 3 Verify the pump oil is clean A badly contaminated pump may require several oil flushes 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 overfill 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 When You If these procedures do not correct the problem 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

6. FROBINAIR Operating Manual High Performance Vacuum Pump Models 15400 and 15600 Robinair High Performance Vacuum Pumps Iso Valve High Vacuum Rating Lifetime Filtration Directed Exhaust Gas Ballast Sure Grip Handle Compact Design Congratulations on purchasing one of Robinair s top quality vacuum pumps Your pump has been engineered specifically for air conditioning and refrigeration service and is built with Robinair s proven offset rotary vane for fast thorough evacuation You ll appreciate these key features 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 The two stage offset rotary vane design provides powerful quiet high vacuum capability and ensures moisture removal while the high pumping capacity reduces evacuation time The intake filter prevents foreign matter from entering the pumping chamber and an internal exhaust filter separates oil vapor from the exhaust flow Exhaust is expelled through the handle to direct it away from the service technician A precise amount of atmospheric air is introduced into the pump preventing condensation of moisture vapor and helping maintain the purity of the pump oil By using the gas ballast the pump operates more ef

9. il 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 Before connecting your vacuum pump to an A C R system 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 fitting 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 vacuu
