Ensure the pulley and sheave are properly aligned and the motor anchor screws are adequately retightened prior to restarting the compressor.

•CAUTION Improper pulley/sheave alignment and belt tension can result in motor overload, excessive vibration, and premature belt and/or bearing failure.

To prevent these problems from occurring, ensure the pulley and sheave are aligned and belt tension is satisfactory after installing new belts or tensioning existing belts.

ELECTRIC DRAIN MAINTENANCE _____________________

NOTE	The following maintenance schedule has been
	developed for typical applications. Maintenance
	intervals should beshortened 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 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.

Position of weight and thrust pin when unit is operating.

6.When putting the EDV-2000 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 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.

•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.
