AIR PUMP AND FILTER ASSEMBLY
Refer to the Air Fuel Ratio Module Installation and User Guide (P/N 98295110) for
proper operating and maintenance procedures. Refer to the Flow Meter User Guide
(P/N 98129104) to test your air pump for accuracy. Failure to follow proper
procedures may result in inaccurate data or damage to the equipment. These manuals
can be found on your WinPEP CD or at www.dynojet.com.
Note: The Air Pump Assembly has a twelve month warranty.
• Dynojet recommends running the pump between dyno runs to help reduce the
chance of moisture contamination on the sensor.
• Remember to empty the exhaust collection bottles regularly.
• Leaks in the system will result in erroneous readings. Verify there are no cracks or
holes in the hoses and filter bowl. Verify the sensor is seated properly in the sensor
block.
• Do not allow the filter bowl to fill with water during operation. Refer to the Air Fuel
Ratio Module Installation and User Guide for filter bowl information.
• Before turning the pump on, verify there is no water in the filter bowl. Always
empty the bowl before turning the pump on.
• Always allow the air pump to run after the dyno runs are complete to clear all water
from the filter bowl and allow the air pump to cool.
Leaded racing fuels and two-stroke applications will contaminate the sensor
and dramatically shorten its service life.
The sensor is not covered by a warranty. Be sure to read and understand the Air
Fuel Ratio Module manuals.
Running the pump with the filter clogged, hose kinked, or filter removed will
damage the pump and void the warranty.
