5. Turn the unit on and let the engine crank (or
crank the engine) for 30 seconds, but do not
crank the engine for more than 30 seconds.
a. Note the pressure at the oil pressure access
port and the suction pressure below the
throttling valve while the engine is
cranking. Subtract the suction pressure
below the throttling valve from the
pressure at the oil pressure access port to
get the net oil pressure.
b. If the compressor does not develop at least
10 psi (96 kPa) of net oil pressure in the
first 30 seconds, allow the starter to cool
for a few minutes and the crank the engine
again for 30 seconds. If 10 psi (96 kPa) of
net oil pressure still does not develop, first
check the compressor oil level, then check
the compressor oil pump and relief valve.
6. As soon as the compressor develops 10 psi
(96 kPa) of net oil pressure, re-connected the
fuel solenoid wires, but do not re-connect the
high speed solenoid wires.
7. Start unit and run the engine on low speed for
at least five minutes. If the net oil pressure is
above 20 psi (138 kPa) for this period, stop the
unit and re-connect the high speed solenoid
wires.
8. Run the engine on high speed for at least five
more minutes. The compressor oil pump is
now primed and broken in.
