Installation:
CSWE1
Proper installat ion is a necessit y, becau se an
improper installat ion will cause operation al
problems that are NOT cove red by any warra nt y. It
is the customer’ s resp on sib ility to contact a
qualified installer.
Proper electrical supp ly, water supply and floo r
drain must be a v ailable. An elec trical ground is
required.
Do NOT clo se in the fron t o f th e ice mak e r. The ice
machine requires space at the fro nt base to
discharge warm air.
If required by sanitation codes, seal the cabinet to
the floor with an appro v e d sealant. Legs are not
available for this machine.
Locatio n:
The ice machin e must be insta lled indo ors , in a
controlled en vironment. Th ere must be room to
open the ice machine door and room to mo v e the
ice machine out for service, if needed.
The unit may be built in at the to p, sides and bac k.
Electrical:
Follow all local, state and national codes. If
needed, obtain the services of a licensed
electrician.
1. A separate 115 v olt, 15 amp circuit is
recommended. A ground is required.
2. Do not use an ext en sio n cord . Have a grounded
outlet insta lled close enoug h to the planne d
installed posit ion of the ice machin e so that th e ice
machine’ s plug can be plugged in directly.

compression fit ting on the inlet w at er v a l v e . There
is an acc e s s ho l e i n the back of th e cabinet fo r
rout ing the tube.
1. Remove the two screws in the lower grille area
and one screw from the center pane l support. Pull
forwa rd and down to remo v e the lowe r acce ss

2. While th e panel is off , rotate the f an t o check
that it moves freely.
3. Open the ice bin door, and slightly loosen, but
Do Not Remov e the thumb scre ws ho ldin g the
cutter grid and water pan in place.
4. Have a shut off va lv e ins ta lled on the potab le
cold water supply tubing near the ice machine.
5. Connect to the shut off valve sufficient length of
1

6. Route the
the back of the cabin et . If the machine is to be built
in, route the tubing so that it will extend past the
front of the cabinet when the cabinet is pushed
into its insta lled pos itio n.

7. Flush the wat er line int o a buc k et to discharge
any dirt that may be in the line.
8. Loc at e the drain tube at the bac k of th e c abine t.
Determine the required locat ion of the dra in tu be
when the cabin et is in its cor rect posit ion, and
install a 1
below where the drain tube outlet will be. Add
insulatio n to the outside of the drain tube if d esire d.
Follo w all local code s regardin g requireme nt s f or

9. Plug the i ce machine into a grounde d outlet.
10. Slid e the ice mac hin e back and observe that
the water inlet tube mo v es f orw ard thru the ice
machine.
11. An adapter fitting is furnished in the ice
machine’s parts bag. Place it on the inlet water
valve and connect the 1/4" OD tube to it. Be sure it
is water tight .
12. Check the level of the ice machin e fro nt to bac k

Initial Start U p
Note: If the ice mach ine is inst alled above 2, 00 0 ft.
the bin and e vaporato r th e rmo stats well need to be
adjusted. Remove the thermostats and adjust
them as shown on the labels of the thermo sta ts.
Return the thermostats to their original positions
after adjustment.
1. Open the hand water shut off valve and check
for lea ks at the inle t w at er valve. Tigh te n tub ing as
needed.
2. Replace the lower access panel.
3. Switch on the elect rical pow er.
4. Switch the ic e machine on by rot at ing the cont rol
knob to the CLEAN po sitio n. The water pump
should be oper ating.
5. Rotate the co nt rol kno b to th e ON pos itio n. The
fan in the cabinet should be blowing air in and out
of the front grill.
The ice machine will begin to mak e ice , bu t do not
expect much production for the first 3 hours.

Do not adjust ice th ickness until the machine has
run for 24 ho urs.
6. Aft er 24 hours of run time, chec k the ice

What to expect:
CSWE 1
When the machin e is on, and makin g ice the
compressor , f a n moto r and wat er pump will b e on.
Pe riodica ll y, the water pump and fan will stop and
ice will be "harvested".
Wat er flo ws o v er an inclined freezing surface, and
gradually free zes into a slab. The ice siz e
thermostat measures the temperat ure of the
freezing su rface and the setting of that the rmost at
determines the thickness of the slab.
The ice machin e must ha ve good vent ilat ion in
order to work properly. Do NOT block the air flow
in front of the mach ine .
During the ice release cycle, the ice slab slide s
down onto a hot wire cutter grid and, aft er the grid
melts thru the ice, the individua l cubes f a ll into the
ice storage bin portion of the machine.
The ice machin e will contin ue to prod uc e ice until
the bin is full. Then the ice machine will shut do wn
until the lev el of ice in the bin f alls below the bin
thermostat well.
The ice storage bin is not refrigerated, so there will
be some melting. This will vary with the
temperat ure of the room whe re th e ice mac hin e is
located.

Maintenance:
The water syste m, inclu ding the filt er scree n in the
inlet water valve, needs to be cleaned period ica l ly.
Instructions are located on the inner door panel.
Water System Cleaning:
1. Place the cycle cont rol knob in th e Off position.
2. Remove the two thumb screws, and slide the ice
cutter grid f orw ard, out of the tw o slot s near the
water pan.
3. Unplug the electrical harness.
4. Remove all ice from the storage bin and the
freezing pla ce .
5. Dra in t he w ater pa n by re mo ving th e drain plug.
When finish ed , repla ce the drain plug.
Prepare the clea nin g solu tio n b y thoroughly mixing
2 ounces of Scotsma n Ic e Mach ine Clean er int o 2
quarts of hot (95
solution is 6 ounc es of powde red citric acid and 2
quarts of hot water.
7. Pour cleaning solution into water pan and turn
the switch to "Clean". If solution foams while
pouring, stop until fo amin g su bsid es , then add
balance of solution. Allow solut ion to circulate until
scale has disso lv ed . The circulating so lut ion ma y
not cont act scale on th e side fla ng es of the
freezing plate. To remov e this scale, wear rubber
glov es an d use a sta inle ss st ee l spon ge or pad
dipped in cleaning solution to scrub the side
flanges until the scale is removed. Generally scale
will be dissolved in 15 to 30 minutes . Se v ere scale
formation may req uire rep ea tin g the clea nin g
process with a fresh qu an tit y of solut ion if the scale
has not dissolve d afte r 30 minu tes.
