Oil Contamination Error
The MAX is equipped with a patented “Oil Contamination” sensor that can detect the presence of
cleaner and water, in the conditioner supply tank. The “Oil Contamination” sensor is your protection
for the critical system components such as the Oil Injector Rail and Accumulator Rail assemblies.
All components for the conditioning system are critical and can lead to extensive repair costs – not to
mention hours worth of work.
How the Oil Contamination Sensor Works
If cleaner and water are introduced into the conditioner tank, the cleaner and water will sink to the
bottom of the tank because oil is lighter than water. The cleaner and water will bridge the stainless steal
pipes inside the tank, then creates a signal that is sent to the electronic enclosure causing the Oil Tank
Vent and Oil Pressure Valve to open allowing the conditioning system to depressurize. If the oil pump is
running, it will turn off immediately to prevent the contamination from circulating through the system.
To see the error refer to Figure 7-15.
Procedures for Removing Contamination
If the Conditioner Tank becomes contaminated by cleaner and water, follow these steps to ensure that
you have properly resolved the contamination issue.
Tools needed:
IPA99, 1/8” Allen wrench, 3/8” socket for a ¼” ratchet drive or 3/8” wrench, shop rag or towel
1. Removing the conditioner tank
a. Turn off power on the left-side (7-pin) side of the machine and disconnect the battery from
the electronic enclosure.
b. Remove the two battery clamps with the 1/8” Allen wrench and set aside.
c. Remove the battery and set aside with the clamps.
d. Remove the frame support with the 3/8” socket or wrench (support is between the
conditioner tank and battery).
e. Place the rag or towel underneath the conditioner supply and return tubing and slowly
remove tubing to prevent drips. The oil in the tubing will drain back into the conditioner
tank.
f. Disconnect the conditioner tank vent tube and the level sensor below the tank.
g. Remove the two conditioner tank mounting screws on the outside of the frame wall with
the 3/8” socket or wrench.
h. Carefully remove the conditioner tank disconnecting the two contamination sensor wires
from the assembly.
i. Take the tank to a work area. The tank will lay on the long at side as it does in the lane
machine when in transport position. This will prevent the tank from leaking.
2. Cleaning the conditioner tank
a. Empty the contents of the tank into a waste container.
b. Pour in the IPA99 until the conditioner tank is half full and place cap back on the tank.
1) Take a piece of 3/8 tubing into the supply and return ttings.
2) Cover the oil tank vent tting to prevent leaking.
3. Agitate the conditioner tank for a minute and let sit for another 5 minutes.
4. Empty the conditioner tank into the waste container and allow the conditioner tank to air dry
(the IPA99 will force water in the tank to evaporate).
