MAINTENANCE
NOTE
The following maintenance schedule has been developed for typical
applications. Maintenance intervals should be shortened in harsher
environments.
DRAIN VALVE MAINTENANCE SCHEDULE
DAILY
Test the valve for proper
operation.
Clean the filter screen if needed.
MONTHLY (EVERY 30 DAYS)
Clean the filter screen.
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.
CAUTION
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 I 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.
6. When putting the Electric Drain Valve back into service, press the
TEST button to confirm proper function.
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 the nearest I–R Air Center or distributor, or call 1–800–AIR
SERV.
If the tank has not been inspected within the first 10 years of
compressor service, the tank must be taken out of service until it has
passed inspection. Tanks that fail to meet requirements must be
replaced.
WARNING
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.
