TM In order to make the best use of your investment, familiarize yourself with the new features and operating instructions before starting pump. With just routine care your FastVac will give you years of reliable service by following proper maintenance guidelines. FastVac pumps are designed for deep vacuum work in refrigeration systems only. EXHAUST DV-42N, DV-85N, DV-142N, DV-200N and DV-285N, Deep Vacuum Pumps, OPERATING INSTRUCTIONS, & PARTS MANUAL, 2-Stage, Direct Drive INTAKE 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. Each FastVac pump has been factory tested to guarantee 25 micron or better and listed CFM performance. The serial number has been recorded. Complete and mail the Warranty Registration Card within 10 days of purchase to validate your warranty. You will be notified of any technical updates.

IMPORTANT This unit has been drained for shipment. DO NOT ATTEMPT TO OPERATE WITHOUT ADDING OIL. 1 ISOLATION (BLANK-OFF) VALVE OIL CAPACITY DV-42N 30 oz. (865 cc) OPEN POSITION DV-85N 27 oz. (785 cc) DV-142N 23 oz. (660 cc) PAUSE POSITION Being just a teaspoon low affects the ultimate vacuum. DV-200N 23 oz. (660 cc) CLOSED POSITION DV-285N 24 oz. (705 cc) Slowly add oil until oil level rises to the top of OIL LEVEL line. Replace oil fill plug. If oil is too low, you will hear the exhaust baffle chatter. If the oil level is too high, excess oil will be blown out the exhaust. Pump oil should be changed after each use. If system is heavily contaminated, oil may have to be changed several times during evacuation. OPERATION IMPORTANT DO NOT START PUMP BEFORE ADDING OIL The following procedures will prevent oil from being drawn into cartridge and creating hard start-up. START-UP Open one intake port and isolation valve, close gas ballast valve and start pump. Make vacuum connections. 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. SHUT-DOWN Crack gas ballast valve. Continue running pump for 2-3 seconds. With valve still cracked, stop pump. Close isolation valve and gas ballast valve. Remove hose connections and cap intakes. CHANGING OIL To reach deep vacuum, FastVac pumps need clean, moisture-free oil throughout evacuation. Quarter-turn on/off. No additional valve needed to isolate system. When checking pressure rise, slowly turn handle counter-clockwise. Pause at 45°. Valve completely closed at 90°. PUMP MOTOR 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 will affect this somewhat. Motor has automatic resetting thermal overload protection. FastVac is designed for continuous duty and will run for extended periods without overheating. DIGITAL VACUUM GAUGES Care should be taken to avoid contact on skin and clothing when changing oil. Used oil should be disposed of in a leakproof corrosive-resistant container. 1. After every evacuation while pump is warm and oil is thin, place pump on level surface and open oil drain. Oil can be forced from the pump by opening one intake 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. DV-22 Battery 2. Close drain. Remove oil fill cap and fill to top of OIL LEVEL line with FastVac Pump Oil. Replace oil fill cap. DV-20 Battery/Electric FLUSHING If the oil is badly contaminated, flushing may be necessary. Slowly pour 1/3–1/2 cup of fresh FastVac 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.

Power cord not plugged in securely. 1. Plug power cord in securely. 2. Motor switch not on. 2. Turn motor switch to ON position. 3. Pump temp. below 30°F. 3. Warm up pump to 30°F & turn motor switch on. 4. Inconsistent line voltage. 4. Line voltage must be within 10% of 115 volt. 1. Contaminated oil. 1. Change oil. 2. Oil level too low. 2. Add oil. 3. Air leak in system being evacuated. 3. Locate & repair leaks. 4. Gas ballast O-ring dirty or cut. 4. Clean or replace O-ring. 5. Pump inlet fittings missing or not tightened. 5. Replace or tighten. Oil drips from point where shaft enters the pump housing. Damaged oil seal. Replace. Pump shuts down and will not start. Thermal overload may be open. Disconnect pump from system. Wait about 15 minutes for motor to cool and turn it on again. If it cycles off again, return pump to factory for repair. Pump cycles on and off from a completely cold start and then runs smoothly. Oil backed up into cartridge and was being cleared out. Pump has not been shutdown properly. 1. Remove 1/4" cap. Pump won’t start. Pump won’t pull deep vacuum. 2. Move blank-off handle to open position. 3. Turn pump on. WARRANTY FastVac pumps are warranted against defects in materials and workmanship for 1 year.
