1. Lay a straight edge across the top outer surface of the belt drive
from pulley to sheave.
2. At the center of the span, perpendicular to the belt, apply pressure
to the outer surface of the belt with a tension gauge. Force the belt to
the deflection indicated in the BELT TENSION TABLE in the DIAGRAMS
& TABLES section. Compare the reading on the tension gauge to the
table.
Follow the procedures outlined below to correctly set and measure
tension on 7.5 through 30 horsepower models 2545, 7100, 15T and
3000 with "B" and "C" belt types.
1. Measure the span length (t) of the drive.
2. Determine the amount of deflection (in inches) required to measure
deflection force (in pounds) by multiplying the span length (t) by
1/64. For example, a 32" span length multiplied by 1/64 equals 1/2" of
deflection required to measure deflection force.
3. Lay a straight edge across the top outer surface of the belt drive
from pulley to sheave.
4. At the center of the span, perpendicular to the belt, apply pressure
to the outer surface of the belt with a tension gauge. Force the belt to
the predetermined deflection
calculated in step 2. Compare the reading on the tension gauge to the
BELT TENSION TABLE in the DIAGRAMS & TABLES section.
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.
DIESEL ENGINE REPLACEMENT
If a diesel engine must be replaced, the following speed adjustments
must be made from the factory settings. These settings should be
made with the belt installed and 0 psi in the receiver tank.
For Yanmar diesel engines:
Adjust the stop screw to set the high engine speed to 3450 RPM
(+/- 25 RPM). No adjustment is required to the low speed setting.
For Kohler diesel engines:
Adjust the stop screw to set the low engine speed to 1625 RPM
(+/- 25 RPM). No adjustment shall be made to the high speed setting.

ELECTRIC DRAIN MAINTENANCE
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.
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.
NOTICE
The following maintenance schedule has been developed
for typical applications. Maintenance intervals should be
shortened in harsher environments.
DRAIN VALVE MAINTENANCE SCHEDULE
DAILY
MONTHLY (EVERY 30 DAYS)
CAUTION
Strainer Ball Valve
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.
Test the valve for Proper
operation. Clean the filter screen
if needed.
Clean the filter screen.
