Read all safety warnings and instructions. Failure to follow the warnings and instructions may
result in electric shock, re and/or serious injury. Save all warnings and instructions for future
reference.

IMPORTANT SAFETY INFORMATION
The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible
conditions and situations that may occur. It must be understood by the operator that common sense and
caution are factors which cannot be built into this product, but must be supplied by the operator.
To avoid electric shock, the power cord protective grounding conductor must be connected to a
properly grounded AC outlet.
Use a proper A.C. outlet for the unit to operate correctly. See unit ID plate on back of unit. Extension
cords are not recommended. If an extension cord must be used, use: 16 AWG for cords up to 50’,
and 14 AWG for cords greater than 50’ but less than 100’.
Connect the power cord to a properly grounded outlet. DO NOT remove or bypass the grounding pin.
Electric shock and fire can cause injury or death.
Risk of expelling refrigerant under pressure. Wear safety goggles and protective gloves, If any
refrigerant gets into eyes, flush with water and seek a doctor’s aid immediately, even though
irritation may cease.
Prevent refrigerant from contacting the skin. Expelled refrigerate can cause injury.
Risk of explosion. DO NOT use compressed shop air for leak detection or to pressure test a system
containing refrigerant. Refrigerant can form combustible mixtures at pressures above atmospheric and
with air concentrations greater than 60% by volume.
DO NOT heat a container of refrigerant above 125°F (52°C).
DO NOT use this equipment in the vicinity of spilled or opened containers of gasoline.
Avoid breathing air conditioning refrigerant and lubricant vapor or mist.
DO NOT allow refrigerant to contact open
ame or b e d rawn into a running engine. T his can cause
refrigerant to become poisonous phosgene gas.
Use ECO to remove refrigerant from air conditioning systems. Exposure can irritate eyes, nose and
throat.
Engine systems can malfunction expelling fuel, oil vapors, hot steam, hot toxic exhaust gases, acid,
refrigerant and other debris. Wear safety goggles and protective gloves, user and bystander. Engine
systems that malfunction can cause injury.
Engine compartment contains electrical connections and hot or moving parts. Keep yourself, test leads,
clothing and other objects clear of electrical connections and hot or moving engine parts.
DO NOT place test equipment or tools on fenders or other places in the engine compartment. Contact
with electrical connections and hot or moving parts can cause injury.
Service hoses can not withstand high temperatures or severe mechanical stress. Keep the service hoses
away from moving or hot engine parts. Service hoses can split or burst causing injury.
Removing tubing assemblies from the pump may discharge refrigerant. Wear safety goggles and
protective gloves, user and bystander. Refrigerant may cause injury.

SAVE THESE WARNINGS
IMPORTANT SAFETY INFORMATION
A test vehicle may move if not properly secured. Block the drive wheels before performing a test with the
engine running. Unless instructed otherwise, set the parking brake and put the gear selector in neutral
(manual transmission) or
park (automatic transmission). If the vehicle has an automatic parking brake
release, disconnect the release mechanism for testing and reconnect when testing is completed.
DO NOT leave a running engine unattended. A moving vehicle can cause injury.
Hose couplings are not self closing. Always close the valves on the gauge set before disconnecting a
hose. Loosened hose couplings can leak refrigerant to the atmosphere.
Misdiagnoses may lead to incorrect or improper repair and/or adjustment. Do not rely on erratic, questionable,
or obviously erroneous test information or results. If test information or results are erratic, questionable, or
obviously erroneous, make sure that all connections are correct and that the test procedure was performed
correctly. Refer also to the Maintenance/Troubleshooting section and perform tests and make repairs
as required. If test information or results are still suspicious, do not use them for diagnosis. Contact
a qualified technician. Improper repair and/or adjustment may cause vehicle or equipment damage or
unsafe operation.

OPERATION and MAINTENANCE
PRE-OPERATION
In all cases, motors are designed for operating voltages plus or minus 10% of the normal rating. Single
voltage motors are supplied fully connected and ready to operate.
1.
Check the On/Off switch to be sure it is in the OFF position before you plug the pump into an outlet. Remove
and discard the exhaust cap from the end of the pump’s handle.
2.
pump is 180-800ml. Reference the technical data.
3.
to ON. When the pump runs smoothly, replace the cap on the inlet port. This may take from 2-30 seconds
depending on the ambient temperature. After the pump runs for approximately one minute, check the sight
glass for proper oil level. The level should be even with the sight glass oil level line. Add oil if necessary.
NOTE:
To help prolong the pump life and promote easy starting. Follow these procedures for shutdown.
1. Close the manifold valve between the pump and the system.
2. Remove the hose from the pump inlet.
3. Cap the inlet port to prevent any contamination or loose particles from entering the port.
MAINTAINING YOUR HIGH VACUUM PUMP
Vacuum Pump Oil: The condition and type of oil used in any high vacuum pump are extremely important in
determining the ultimate attainable vacuum. We recommend the use of High V
acuum Pump Oil. This oil has
weather starts.
Oil Change Procedure: Be sure the pump is warmed up. Remove the oil drain cap. Drain contaminated oil
into a suitable container and dispose of it properly. 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.
the sight glass. The approximate oil capacity of the pump is 180-800ml.
Be sure the inlet ports are capped then turn off the pump. Allow it to run for one minute then check the oil level
space. If the oil below the sight glass oil level line add oil slowly (with pump running) until the oil reaches the
If the oil is badly contaminated with sludge that forms when the water is allowed to collect in the oil, you may
need to remove the oil reservoir cover and wipe it out.
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
oil.

Failure To Start: Check the line voltage. The pump to start at ±10% line voltage (loaded) at 32 °F. At
extremes, switching between and start and run windings may occur.
Oil Leakage: Be sure the oil is not a residual accumulation from spillage, etc. If leakage exists, the module
cover gasket or the shaft seal may need replacing. If leakage exists in the area of the oil drain plug you may
need to reseal the plug using a commercial pipe thread sealer.
Failure To Pull a Good Vacuum: Be sure the vacuum gauge and all connections are in good condition and
the leak.
Be sure the oil is at the proper level. For maximum pump operation, the oil must not be even with oil level
expand, so it will appear at a higher level than then 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.
