COMPRESSOR OPERATION

OPERATING CONDITIONS

The following conditions should exist for maximum performance of the compressor.  The truck

should be as close to level as possible when operating.  The compressor will operate on a 15

degree sideward and lengthwise tilt without any adverse problems. Operation in ambient tempera-

tures above 100°F (38°C) may experience high temperature shutdown.

NOTE

NOTE

IF THE COMPRESSOR IS BEING USED TO POWER SANDBLASTING EQUIP-

MENT, OR AN AIR STORAGE TANK, USE A CHECK VALVE DIRECTLY AFTER
THE MINIMUM PRESSURE VALVE TO PREVENT BACKFLOW INTO THE SUMP.
THIS CHECK VALVE SHOULD HAVE A MAXIMUM PRESSURE DROP RATING
OF 2 PSIG (13.78kPa) OPERATING AND A CAPACITY RATING EQUAL TO THE
COMPRESSOR.

A  COMPRESSOR SERVICE VALVE SHOULD BE LOCATED TO THE HOSE REEL
INLET OR THE CUSTOMERS AIR CONNECTION PORT WHEN A HOSE REEL IS
NOT USED.  TYPICAL PLUMBING FROM THE MACHINE’S AIR OUTLET PORT
OCCURS IN THE FOLLOWING ORDER:

1.

MOISTURE TRAP/GAUGE/OILER COMBINATION (WHEN USED).

2.

AIR TANK (WHEN USED).

3.

HOSE REEL (WHEN USED).
