FOR THE INSTALLER

Location:

Prior consideration for the location shall inc lud e:

••Indoors, with a minimum room tempe ratu re of

F. and a maximum room temperature of

100

••Water tempera tu re to the machin e sh ou ld be

betwee n 40

F. and 1000F.

•• Service Access. Allow enough space at the

back of the cabinet for the utilit ies to be connected. Allow enough space for the machine to be pulled out from its ins talled location. Do not build a floor in front of the machine that would preve nt its remov al.

••Air circulation: The front pane l MUST remain

unobstruct ed . Do not blo ck with any type of door or curtain .

If the unit is built in, it will pull air in from the right side of the front panel, and exhaust it out the left side of the front panel. If the left side of the machine is left open, warm air will be discharged from th e left sid e panel.

IF BUILT IN, THIS SIDE

SHOULD BE TIGHT AGAINST

FOR THE PLUMBER

Wat er sup ply an d dra in conne ct ions.

1.The recomme nd ed water supp ly line is a 1/4" o.d. coppe r tube , th e water pressure must have a minimum incoming pressu re of 20 psig.

2.Con ne ct th e tubin g to the 3/4 " hose cou plin g thread water inlet fitting at the back of the ice maker. An optional adapter to go from the 3/4" hose coupling thread to 1/4" compression fitting is available fro m your de ale r under p art numbe r

0533238. Or a similar adapter can be purchased from a

hardware store.

POWER

SUPPLY

3.Install a shut off valve in the incoming water line near the ice maker so that the water can be shut off for service.

4.Con nect a gra vity drain line to the dra in connection at the ice ma ker. A minimum slope of 1/4" fall per foot of horizontal run is recommended. Install th e drain s per the loc al codes.

A vent is reco mmended on the highest poin t of the drain tube , and th e drain tubing mu st be rigid pipe. Do NOT use flexible tubing.

ELECTRICAL

1.Locat e th e namep lat e on the lower re ar pane l and check tha t the locat ion sou rc e volt age an d capacity are correct for this unit . The unit is equipped with a grounded plug connection .

Under no circumstan ces must the gro und post be altered or removed.

Extensio n cords are not pe rmitt ed.

ADAPTER

(FIELD SUPPLIED)

Be certain that the ice make r is conn ect ed to its own electrical circuit and is individu ally fused. The maximum allowable volt age varia tio n should not exceed ten percent of the nameplate rating.

All external wirin g shou ld co nform to the National, State, and local electrical code requirements. Usually an electrical permit and

the services of a licensed electricia n will be required to install the receptacle.

FINAL CHECK

1.Is th e Cab ine t level?

2.Have all the electrical and piping connections been made?

3.Has th e voltage been teste d and ch eck ed against the nameplate rating?

4.Is th e unit plu gg ed into a sep arat e ele ct ric al circuit?

5.Is the wat er sup ply line shut of f valv e inst alle d and is the water turned on?

POWER?

6.Have the bin interior, and the cabinet exterior been wiped clean?

7.Are all int ern al pa rt s in pla ce, including the spray platf orm a nd curtain?

8.Have the internal refrigerant lines been checked for rubbing and chaffing?

9.Has th e machine been installed where it is indoors, in a cont rolled env ironme nt , with adequate air circulation around the machine, and where it can be serv iced ?

INITIAL START UP

1.Open water supply valve.

2.Move electrical breaker or switch to the on position.

3.Remo ve fro nt panel.

4.Che ck th e cube size control sh af t, it shou ld be in a preset cube size posit ion . If not, turn it clockwise until the unit comes on. Note: cube size adjust men ts may be required . St art with the shaft in the "mid" posit ion.

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.

This will take about 3 freeze cycle will begin.

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 down evenly in the openin g and that no larg e streams of water are pa ssin g throug h.

Note: Some wate r will drip from the reservo i r as the machine runs. This is normal.

9.Afte r about 20 minut es the machin e will begin to release the ice , th is is called the harve st cy cle.

Observe the first cube harvest:

••Check the size of the ice cubes.

Note: The normal size of the ice cube has a 1/4" depressio n in the wide end.

If the cu bes are not filled out, adjust the machine to make larger ice cu bes by tu rning the cube size control shaft cloc kwise .
