Cooling water from the heat exchanger
designed to cool the compressor is
plumbed to the tank. When not running
CAFS (i.e. drafting), the tank can overfill.
This solenoid/valve assembly is designed
to be flowing when the clutch solenoid is
engaged.
• Not opening
o No air to 4-way valve.
o Air ports clogged.
o No signal from clutch solenoid.
Thermostatic Oil Bypass Valve
Opens at 150°F (65°C) [fully opening at
170°F (76°C)] to allow the oil to run
through the heat exchanger otherwise it
bypasses the heat exchanger.
• Compressor is overheating
o Not fully opening.
o Oil temperature is above max
operating temperature.
Separates the air and oil through a series
of chambers internally and any
condensation/water, which can be
drained from the bottom ball valve. The
side “arm” is for replacing oil. The top port
with the air valve is for discharging air to
the pump or auxiliary port. The hex on the
side supplies air to the control system for
the compressor.
• Compressor is overheating
o Oil is not at proper level.
o Oil not being cooled by Heat
Exchanger.
o Coolant Valve not opening.
• Air injection/Pressure match
o Hex port on side is leaking
o Brass orifice is missing from
scavenge line.
