To clean the filter screen, perform the following steps:
1. Close the strainer ball valve completely to isolate it from the air
receiver tank.
2. Press the TEST button on the timer to vent the pressure remaining in
the valve. Repeat until all pressure is removed.
High pressure air can cause injury from flying debris. Ensure the
strainer ball valve is completely closed and pressure is released
from the valve prior to cleaning.
3. Remove the plug from the strainer with a suitable wrench. If you
hear air escaping from the cleaning port, STOP IMMEDIATELY and
repeat steps 1 and 2.
4. Remove the stainless steel filter screen and clean it. Remove any
debris that may be in the strainer body before replacing the filter
screen.
5. Replace plug and tighten with wrench.

TANK INSPECTION
The life of an air receiver tank is dependent upon several factors
including, but not limited to, operating conditions, ambient
environments, and the level of maintenance. The exact effect of these
factors on tank life is difficult to predict; therefore, Ingersoll Rand
recommends that you schedule a certified tank inspection within the
first five years of compressor service. To arrange a tank inspection,
contact Ingersoll Rand.
If the tank has not been inspected within the first 10 years of
compressor service, the receiver must be taken out of service until it
has passed inspection. Tanks that fail to meet requirements must be
replaced.
Failure to replace a rusted air receiver tank could result in
air receiver tank rupture or explosion, which could cause
substantial property damage, severe personal injury, or death.
Never modify or repair tank. Obtain replacement from service
center.
