5. The machine will go thru a "dry" cycle, this will
take about 10 minutes. Th en the water f ill and
harvest cycle will begin.
6. Observe the water fill cycle:
••The water inlet valve opens .
••Incoming wate r flows from th e valve th rou gh
the tubing to the top of the ice maker.
••Water flows around the inverted ice cube
cups an d drains through holes into the
reservoir.
•• The reservoir begins to fill up with water.
••Water continues to enter the machine and
overflows a stan dpipe in the reservo i r and
dow n the dr ain.

7.Che ck th e operat ion of the fre ezin g cyc le:
⁄2 minutes. Af te r th at th e
If the cu bes are overfilled, adjust the machine to
make smaller ice cubes by turnin g the cube size
control counter-clockwise.
In both cases , th e ne xt cyc le of cube s harv ested
must be observed, and further corrections may
be needed.
If the ice cubes are cloudy, an extreme water
condition may exist. Confirm that they are
cloudy by pla cing them in a glass of co ld water.
If, in the water, they remain cloudy, you may
want to have the water tested by a water
treatment specia list.
If the ice cubes are cloudy only on the bottom or
in the center, the machine ma y be running out of
water before the end of the fre ezin g cyc le.
10. Test the bin full shu t of f. To test this, ho ld
some ice on the bin thermo sta t bra cke t (t he
stainless steel tube on the left side of the ice
storage bin ). The ice maker sho uld stop within a
few minutes of having ice on that tu be.
1 1 . Fill out the W a rra nty Re gis trat ion and
Customer Evaluation form, and mail both to
Scotsman.
12. Make sure the user unders tand s the
operatio n and mainte na nce requ i remen ts for the
ice maker. Leave the service manual and the
name of the local Scotsma n service agen cy with
the us er.
••Compressor is running.
••Water pump is spraying water through the
spray nozzles.
••Ice making begins, the wat er gets very co ld,
and ice begins to form in the cube molds.
8.Che ck th at the plast ic curt ain asse mbly ha ngs

COMPONENT DESCRIP TI ON
Cube Size Control
The cube size control is loca te d in front of the
control box, behind the fron t pa ne l. Th e se nsing
capillary tube of the cube size control is routed
out of the control box int o its bulb ho lde r on the
evaporator coil. It is a reverse acting
temperat ure cont rol with doub le throw con ta ct s.
Turn ing its knob all the way coun terc lock wise
also shuts off the ice maker.
The control det ermine s th e len gth of the
freezing cyc le and corres pond ing ly the size of
the cube. A lo wer settin g will produce a smaller
cube, and a higher setting will make a large r
cube. The cube size control changes its
contact s whe n th e eva po rat or reaches its preset
temperature, starting the harvest cycle. When
the sensing tu be of the cu be siz e control
reaches th e hig h pres et temp erature, the
contact s cha nge again, restarting the freez e
cycle.
Compressor Toggle Switch.
The compressor toggle switch is located on the
side of the control box. When move d to the ON
position, it make s a circuit to the compres sor.
When moved to the OFF posit ion , th e other
components will still operate.
Water Pump
The water pump operates during the fre ez ing
cycle only, pumping water thro ug h the spra y
nozzles int o the inve rte d spra y cups.
Inlet Water Solenoid V al ve
The water sole no id valv e, locat ed in the bac k
panel of the unit, is energized only durin g the
harvest or cleaning cycle s. When energized it
allows a metered amou nt of wat er to flow int o
the machine (.21 g.p.m.) This water flows to the
top of the evaporator and then down into the
reservoir.
Bin Thermostat Control
The bin thermo st at control bo dy is loca te d in
front of the control box just beside the cube
size control. The thermos ta t se nsin g tub e is
located in the ice storage bi n on the lef t side wall
where is automa tic ally sh uts the ice make r of f
when the bin is full and rest arts when ice is
removed. Factory settings are 1 degree C (36
degrees F) cut out and 4 degrees C (39 degrees
F) cut in. It can be adjusted by turning the
adjustment screw visible through the contro l box
cover.
Hot Gas V alve Assem bly
The hot gas valve assembly is comprise d of two
parts, the valve body and the coil. These p arts
are located on the discharge line of the
compressor and are activated by the cube size
control (harvest cyc le). When the coil of the hot
gas valve is energized, it magn etically lifts the
plunger in the hot ga s valve body. This allows
hot refrigerant gas to by-pass th e co nden ser
and go directly to the evaporator.
Spray Pla t form and Chute
The spray syst em use d on this unit is of the
station ary typ e. The water is forced by the
water pump into the pla tf orm chambe r and
spraye d int o the inve rte d cup mo lds throu gh a
set of six spray nozzles.
Fan Motor
The fan motor is electrically connec ted through
the cube size control and runs only durin g th e
freezing cyc le.
Hermetic Motor Compressor
The compress or is a vapor pump , fo rcing
refrigera nt gas throu gh ou t the refrigeration
system.

WATER
Freezing cycl e
The refrigerat ion proce ss crea te s cold
temperatures within the evaporator coils and
removes heat from the wat er spra yed up into
the inverted ice cube cup s. When enough heat
is removed, the wat er cha nges into ice, and
forms where it is the coldest: in the ic e cube
cups.
Minerals contain ed in the supply wat er will not
freeze and are drained away. Mostly pure water
will be frozen into the ice cubes.
During the freezing cycle , the compres sor, fan
motor, and water pump are operatin g. Wa te r is
continuou sly free zing or being sprayed and
recirculated. When evapora tor temperature is
lowered to th e cold temp era tu re set tin g of the
cube size control, it ends the freezin g cyc le an d
starts the harvest cycle.
Harvest cycle
The hot gas valve opens an d hot
refrigera nt gas is disc ha rged into the
evaporat or.
The inlet water valve opens an d a fresh
supp l y o f wa ter flows t o th e top of the
evaporat or and th en drains into the
reservoir.

FREEZE
The cube size control th ermo stat senses the

The harvest cycle is comple te , and the free zin g
cycle restarts .
The automatic ic e making pro ces s con tin ues
until the bin is full of ice, and the bin thermostat
senses a cold er te mpe ra tu re.
The bin thermostat then opens the circuit to all
components and the automatic ice making
process stops.

HOW IT WORKS:
FREEZE CYCLE
REFRIGERATION
The ice cubes are forme d in an inve rt ed mold
that is refrigerated.
The refrigerat ion proce ss be gin s at the
compress or. The re, ref rige rant vap or is
compressed and flows from the compressor
throug h the discharge line as a high
temperature, high pressure g as. In the
discharge line th ere is a stra ine r with two
outlets , on e lea ds to the cond enser, and one to
a solenoid valve . Be cause the solenoid valve is
closed, the gas flows to the condenser, where
heat is transferred from the ref rigera nt to the air
passing throu gh the con de nse r. The refrigerant
then condenses into a high pressure liquid.
EVAPORAT OR
From the condenser, the liquid refrigerant flows
throug h the liquid line , and the liqu id line
filter-drier. Af ter t he filter drier, the liquid
refrigerant enters the metering device, a
capillary tube. Af te r pas sing the restriction of
the capillar y tube, the refrigerant enters an area
of relative low pre ssu re, th e ev ap orator. In the
tubing of the ev aporator, the liquid refrigerant
expands and evaporates, absorbing heat from
the evaporat or tu bing and anything in contact
with it such as water sprayed against it.
The refrigeran t, now a low pressure, low
temperat ure va por, flows into the accumul ator,
which traps exc ess liquid refrigerant. The vapor,
now primarily a gas, goes through the suction

HARVEST CYCLE
(When the cubes are released)
The ice cubes hav e be en formed in an inv erte d
mold that was refrigerated.
Now the refrigeratio n system will c hange to
warm the cube mold and release the cubes.
The process begins at the comp ressor. There,
refrigerant vapor is compress e d and flows from
the compressor through the di scharge line as a
high temperature, high pressure gas. Before
the gas gets to the con de nse r,it goes throu gh a
strainer, the strainer outlet is connected to two
tubes, one of which lead s to an electric va lve,
the hot gas sol eno id. When this valve opens,
the refrigerant gas follows the path of least
resistance and flows through the tu bing from the
EVAPORATOR
hot gas valve to the evapora tor, where the ice
cubes are frozen.
At th e evap orat or, th e high te mperature gases
are cooled by the cold te mpe rat ures of the cube
mold, and cond ense int o liqu id, transfer rin g heat
to the mold which warms up and releases the
cubes.
The refrigeran t, now a low pressure, low
temperat ure va por, flows into the accumul ator,
which traps exc ess liquid refrigerant. The vapor,
now primarily a gas, goes through the suction
line tub e to the compressor where the cycle is
repeated.
