OIL DRAIN EXTENSION
Some models include an oil drain extension and cap. Install the oil drain extension and cap before adding
oil to the pump. To avoid oil leaks, it is highly recommended to apply PTFE thread sealant tape or thread
sealant to the threads on each end of the oil drain extension. Remove the oil drain plug from the base of
the pump and install the oil drain extension.
INSTALLATION INSTRUCTIONS
use unit to lift other attached equipment.
NOTE: If compressor operates in a hot, moist environment, supply compressor pump with clean, dry
outside air. Supply air should be piped in from external sources.
Pump Mounting
VT4823 and VT4923 requires a mounting bolt size of 5/16 inch.
Properly torqued 5/16 inch bolts are torqued to 12 ft/lbs (144inch/
lbs).
Direction of Rotation
NOTE: Improper rotation will result in reduced compressor life.
The direction of rotation must be counterclockwise (as shown by
the arrow on the flywheel) while facing the flywheel side of the
pump. The motor nameplate will show wiring information for
counterclockwise rotation.
The proper direction is very important. The direction of rotation
of 3 phase motors can be reversed by interchanging any two
motor-line leads. For single phase motors, refer to the motor
nameplate.
