The given number of revolutions in both columns are split up
in two range oftums namely, up to and 1ncluding 30 turns or
62 tums.
• Volume ratio is given in the model numberfor each pack
age, shown on the name plate on top of the compressor
discharge housing by a tenfold value (the last two num

4.16 MOTOR ROTATION CHECK
Remove the coupling spacer if fitted.
Check to see that the motor turns freely
by
hand. Supply
power to the motor starter and rotate the start button to the
"Auto-Start· position. Bump the motor by pushing the start
button then pushing the stop button. Verify the motor rota
tion by observing the motor shaft coupling hub.
IMPORTANT
The motor shaft wil/ rotate counterclockwise when facing the
motor
shaft end when
motor rotation
is
correct.
lf the motor rotates in the wrong direction, disconnect the
power supply to the starter at the circuit breaker and reverse
two of the phases by interchanging two of the three electrîcal
lines
at
the starter or at the motor terminal box. Rotate the
slarting switch to the "Manual-Reset" position. Disconnect
power from the motor starter, Do not mount the coupling
spacer and coupling guard.
