Quincy Compressor

™
Water and Sewer Facilities at the Installation Site
(Water-cooled models only)
Make sure the water supply is connected and open.
Piping supplied by the user should be at least equal to the
connections provided on the compressor. Sewer facilities
should be readily accessible to the installation site and
meet all the requirements of local sewer codes, plus those
of the compressor. Make sure water inlet and discharge
connections are correct.
NOTICE!
The water temperature regulating valve is located
in the discharge water line.
Clean air is essential for your Quincy QSB/T
™
compressor. Always select a source providing the
cleanest air possible. When an outside air source is used,
keep all piping as short and direct as possible. Use
vibration isolators and support all piping correctly.
Piping size should be at least as large as the inlet valve
opening and increased several sizes for extremely long
piping runs. The piping must be leak free and clean after
fabrication.
Compressor Rotation
Compressor rotation must be checked prior to start-up.
Proper rotation is clockwise (as viewed from the power-
input end). The power-input end of the compressor is
marked with an arrow noting the proper rotation.
Operating the compressor in incorrect rotation will result
in extreme damage to the compressor and warranty
coverage will be voided. To check for proper rotation,
jog the starter button, allowing the motor to turn 2 or 3
revolutions. Observe the drive element for correct
direction. If incorrect rotation is observed, lock out
power supply, reverse electrical leads L
1
and L
3
at the
motor starter. Recheck for correct rotation.
Fan Rotation
Check the fan rotation at the same time the compressor
rotation is being checked. Fan airflow should be outward,
that is, pushing the air through the coolers on air-cooled
units or out of the cabinet on water-cooled units with
cabinets.
