11. _____
Check compressor rotation of the scroll compressor using the following procedure:
Move the selector switch to the “Ice” position and press the “Harvest/Start” switch. The liquid line
solenoid valve (20) will open and feed liquid into the evaporator for approximately 2 minutes. The
machine will not operate until the low pressure rises sufficiently (to approximately 40 psig) to close
the low-pressure switch (4PS) & open the cylinder ice freezer pressure switch (FPS2). Suction
pressure must decrease and discharge pressure increase immediately. A scroll compressor will also
be very noisy when rotating in the opposite direction. To change rotation, reverse two (2) of the
three (3) compressor wires L1, L2, and L3 either at the control panel terminal block, or at the
compressor junction box.
CAUTION:
Always disconnect power to the machine before attempting
electrical modifications.
! CAUTION !
If the compressor runs backwards for an extended period of time, damage may occur
to the compressor and the warranty may be voided.
! CAUTION !
12. _____ Once the water has been primed, move the selector switch to the “Ice” position and push the
“Harvest/Start” switch. The liquid line solenoid valve (20) will open and feed liquid into the
evaporator for approximately 2 minutes. The machine will not operate until the low pressure raises
sufficiently (to approximately 40 psig) to close the low-pressure switch (4PS) & open the cylinder
ice freezer pressure switch (FPS2).
13. _____ Operate the machine several cycles while completing the
Warranty/Registration Start-up
Form
. Mail the completed report in the postage paid envelope or fax to 800-770-8648.
! CAUTION !
If it should ever become necessary to add refrigerant to the system, charging valve (28)
is provided for this purpose. Be sure to follow all local and federal regulations regarding
the handling of refrigerants and their illegal emission into the atmosphere.
! CAUTION !
