Introduction
Each PLATINUM® vacuum pump has been factory tested to guarantee 15 microns or better, and listed CFM performance. The serial number has been recorded. Complete and mail the enclosed Warranty Registration Card or register online at www.jbind.com within 10 days of purchase to validate your warranty.
NOTE: PLATINUM® pumps are not to be used on Ammonia or Lithium Bromide (salt water) systems. Pump maintenance is the responsibility of the owner.
⚠️ WARNING: UNIT DRAINED OF OIL FOR SHIPMENT. DO NOT OPERATE WITHOUT ADDING OIL.
Motor Specifications
Pump and oil must be above 30°F. Line voltage must be equal to motor nameplate ±10%. Normal operating temperature is approximately 160°F, which is hot to the touch. Line voltage and ambient conditions can slightly affect this. Motor has automatic resetting thermal overload protection.
The PLATINUM® is designed for continuous duty and will run for extended periods without overheating.
Operation
The following procedures will prevent oil from being drawn into the pump cartridge and creating hard start-up.
Start-up
Close both sides of manifold and make connection to vacuum pump or auxiliary blank-off equipment. Open one intake port and isolation valve, close gas ballast valve and start pump. Make vacuum connections (Figure 1).
Crack gas ballast valve for the first part of the evacuation procedure. After pump quiets down from initial volume of air, close valve and continue evacuating. Failure to close valve will result in poor pump performance.
Shutdown
Close isolation valve and open gas ballast valve all the way. Continue running pump for 2-3 seconds. With gas ballast valve still opened, stop pump and then close valve. Remove hose connections and cap intakes (Figure 1).
Isolation (Blank-Off) valve
Quarter-turn on/off. No additional valve needed to isolate system. When checking pressure rise, slowly turn handle counter-clockwise. Pause at 45°. Valve is completely closed at 90°.
Important Notes on Oil
IMPORTANT: Use oil specifically refined for deep vacuum pumps. Using oil not refined for deep vacuum pumps and/or operating with contaminated oil will void warranty.
Pump oil should be changed after each use. If system is heavily contaminated, oil may have to be changed several times during evacuation. After initial fill up, it is best to check oil level with pump running.
After evacuation, oil contains rust forming water and corrosive acids. Drain immediately while pump is warm.
Changing Oil
To reach deep vacuum, PLATINUM® pumps need clean, moisture-free oil throughout evacuation. Care should be taken to avoid contact on skin and clothing when changing oil. Used oil should be disposed of in the DV-T1 TANK Oil Caddy after every evacuation while the pump is warm and the oil is thin.
- Place the TANK on a level surface. Unscrew black plug in drain base to open.
- Place vacuum pump in the cradle and drain pump.
- When pump has finished draining, replace black plug. The TANK can hold up to five oil changes.
- Close oil drain valve on pump. Remove oil fill plug and fill to top of oil level line with BLACK GOLD Pump Oil (Figure 2). Replace oil fill plug.
Flushing Oil
WARNING: DO NOT START PUMP BEFORE ADDING OIL
- Always drain pump before flushing. If the oil is badly contaminated, flushing may be necessary.
- While oil drain is open slowly pour 1/3 to 1/2 cup of BLACK GOLD Pump Oil into the intake connection while pump is running.
- Repeat as required until contamination is removed from oil reservoir, pump rotors, vanes and housing.
- Dispose of all oil used in flushing of pump.
Black Gold Pump Oil
Acts as a coolant, lubricant and sealant simultaneously.
Description of Image: Two bottles of JB Industries Black Gold Vacuum Pump Oil are shown, one 1-gallon container and one smaller container. Below them is the JB Industries DV-T1 Tank Pump Oil Caddy, described as a convenient and portable solution for changing oil between jobs, with capacity for five oil changes.

Pump Maintenance
In order to make the best use of your investment, familiarize yourself with the features and operating instructions before starting pump. With routine care and following proper maintenance guidelines, your PLATINUM® will give you years of reliable service. PLATINUM® pumps are designed for deep vacuum work in air conditioning and refrigeration systems.
Adding Oil
- Remove filter from pump. Slowly add oil until level rises to the top of the oil level line (Figure 2).
- Replace filter.
If oil level is too low, you will hear air out of the exhaust. If oil level is too high, excess oil will be blown out of the exhaust.
IMPORTANT: OIL LEVEL MUST BE ABOVE HALF WAY IN SIGHT GLASS
Description of Figure 2: A diagram showing the oil sight glass with markings for the oil level, indicating it should be above the halfway point.

Troubleshooting
| SYMPTOM | POSSIBLE CAUSE(S) | CORRECTIVE ACTION |
|---|---|---|
| Pump hard to start | A. Power cord not plugged in securely B. Motor switch not on C. Pump temperature below 30°F D. Pump has not been shut down properly | A. Plug power cord in securely B. Turn motor switch to ON position C. Warm up pump to 30°F and turn motor switch on D. Follow proper start up and shut down procedures |
| PROPER START UP AND SHUT DOWN PROCEDURES: Step 1: Close blank-off valve Step 2: Open gas ballast valve Step 3: Run 2 to 3 seconds Step 4: Shut pump off Step 5: Close gas ballast valve | ||
| FOR HARD START-UP SPECIFICALLY: Step 1: Remove 1/4" cap Step 2: Move blank-off valve to OPEN position Step 3: Turn pump on Step 4: Run 2 to 3 seconds and close blank-off valve | ||
| Pump won't pull deep vacuum | In order for your pump to pull to a near perfect vacuum, oil must be clean and moisture-free throughout evacuation. A. Contaminated oil B. Oil level too low C. Air leak in system being evacuated D. Pump inlet fittings missing or not tightened E. Coupler slipping F. Missing or damaged seals or o-rings | A. Change oil B. Add oil C. Locate and repair leak(s) D. Clean or replace o-ring E. Tighten coupler set screws to flats of cartridge and motor F. Replace damaged seals or o-rings |
| OIL LEVEL CHECK: Step 1: With isolation valve closed, start pump. Oil level should be to the top of the oil level line embossed on the front of the pump's cover. Just a teaspoon low can affect the ultimate vacuum. Step 2: Flush pump and refill with fresh oil. Step 3: Check all connections to pump and system for damaged or missing o-rings. If brass adapters are being used, make sure copper gaskets are in place. | ||
| Oil drips from point where shaft enters the pump housing | Damaged shaft seal | Replace shaft seal |
| Pump shuts down and will not start | A. Thermal overload may be open B. Low Battery (DV-142-FLEX or DV-85-FLEX) | A. Step 1: Disconnect pump from system Step 2: Wait approximately 15 minutes for motor to cool Step 3: Turn pump on Step 4: If it cycles off again, return for repair B. Check battery charge; re-charge if necessary |
| Pump cycles on and off from a completely cold start and then runs smoothly | A. Oil backed up into cartridge and was being cleared out B. Pump has not been shutdown properly | Step 1: Remove 1/4" cap Step 2: Turn pump on |
| Motor just hums | If pump has been dropped, the armature in motor may be out of alignment with the motor's bell housing | Step 1: Set pump on bench with motor standing up Step 2: Loosen the four motor bolts Step 3: Shake motor and re-tighten motor bolts Step 4: Start pump If this doesn't work, the pump most likely will need to be sent in for repair. |
| Motor runs, but no suction | A. Flexible coupler is either broken or loose | Step 1: Set pump on bench with motor standing up Step 2: Look between motor and pump housing from the bottom to see if the flexible part of the coupler is split or broken. If the coupler is not broken, the coupler may be spinning on either the shaft to motor or cartridge. Step 3: Replace cartridge. Instructions at www.jbind.com - Support - User Manuals. |
