FOR THE INSTALLER: Locat ion & Assem bly
Location:
Afte r u ncrat in g and inspe ction , th e unit i s re ady fo r
installat ion . It is important that the machine be
installed in a location where it has enough space
around it to be accessible for service . Try to avoid
hot, dirty and crowded locations. Be sure that the
location for the mach ine is wit hin the
environmental limitations.
Storage Bin:
Tip th e sto rag e bin on its back , usin g par ts of the
carton to prot ect the exterior finish. Inst all th e leg s
packed with the BH90 0. If stacking use a heav y
duty leg kit (KLP6).
1. Arrange for prope r elec tric, water and drain. See
instructio ns for the plumbe r and for the electrician.
2. After mounting the legs pos itio n the ice s to rag e
bin in the sele cte d loc at ion :
Note: Allo w eno ugh sp ac e to th e lef t and back t o
service the machine. Do NOT push the bin into
position, inst ea d, lif t it there . Push ing a bin may
damage th e le g s and leg mo unts.
ICE MACHINE AND BIN ASSEMBLY
Level the bin in bo th the fron t to rear and side to
side directio ns by adjust ing the leg levelers .
3. Inspect the bin top mounting gasket. It must be
flat, with no gaps, to pro vide a good wat er se al
when the cuber is insta lled on top of the bin.
Ice Maker:
Install the mod ula r cube r on top of the bin using
care to be sure a good se al is made betwee n th e
two cabinets. Use of a mechanic al lift is
recommended . Alig n the hole s in t he bott om re ar
of the cabine t to mate wi t h the two mo untin g holes
on the top rear of the bin.
Use bolts and straps found on the back of the ice
machine to secu re th e ice mac hin e to the bin.
When alignme nt and levelin g are comp let ed,
tighten the bolts to secure the mounting straps.
Remove the front panel, and remove the
evaporator shipping brackets and hardwa re .
Remote Condenser:
A new condenser coil designed for the machine’s
capacity MUST be used. Because of the possibilit y
of mineral oil contamination, coils and line sets
that had been connect ed to R-12 , R-50 2 or R-22
units MAY NOT BE CONNECTED TO THIS
SYSTEM. Doing so voids the refrig era tio n syst em
warranty.

Select the be st av aila ble locat ion, protecting the
condenser from ext reme s of dirt , dust , and sun.
Meet all applicable bu ildin g codes.
Roof Attachment:
Install and atta ch th e remo te con dense r unit to the
roof of the build ing , us ing the meth ods and
practices of const ruct ion that co nform to the local
building code s, inc lud ing havin g a roofin g
contractor se cure the condense r to the roo f.
Precharged Line Routing
CAUTION
Do not connect prec harge d tubin g until all rou tin g
and forming of the tubin g is complet e. See the
coupling instructions for connecting instructions.
1. Each set of prech arg ed refrig era nt lines co nsis ts
of a 3/8 inch diameter liquid line, and a 1/2 inch
diameter discharge line. Both ends of each line
have quick connec t couplin gs , th e end withou t
access valves goes to the ic e make r.
Note: The openings in the buildin g ce iling or wall,
listed in the next step, are the minimum sizes
recommended for passin g the ref rige ran t line s
through .
2. Have the roofing contracto r cut a minimum hole
for the refrigerant lines of 1.75". Check local
codes, a separat e hole may be requ ired for the
electrical power to the condense r.

CAUTION
The couplin gs on the set s of pre ch arg ed lines are
self sealing when inst alle d pro pe rl y. Carefully
follow the instructions:
Initial Connec tions :
1. Remove the protector caps and plugs. Wipe the
seats and threaded surfaces with a clean cloth to
be certain that no fore ign matt er remains on them.
2. Lubricate the inside of the cou plin gs, especia l ly
the O-Rings with refrige rant oil.
••The 1/2 inch discharge line (schrader valve
end) goes to the remote condense r fitt ing
marked “discharge line”.
••The 3/8 inch liquid line (sch rad er valv e end)
goes to the remote con dense r fitt ing marke d
“liquid line”.
Final Connections :
3. Begin tighte ning the coup ling s tog et her by
hand, then using two wrench es (it is importa nt that
ONLY the nut on the precharged lines be turned,
the other parts of the coupling s must NO T be
allowed to turn or the proce ss will tear out the
diaphragms and they will be loose in the
refrigeration system) tighten the coupling until it
bottoms out or a definite increase in resistance is
felt.

FOR THE ELECTRICIAN
DETAIL OF JUNCTION BOX, 3 PHASE SHOWN
CME1202R & CME1402R
See the ice machine namep lat e fo r curre nt
requirements to determine wire and fuse size to be
used for electrical hookup. When the cuber and
the remote conde nse r are co nnect ed , each must
be grounded to the other usin g the gro un d screw s
provided in the respe ct ive ju nction bo xes . The
cuber then requires a solid chassis to chassis
earth ground wire. See Wiring Diagram.
Be certain the cuber is connected to its own
electrical circuit and individ ually fus ed. Voltage
variation should no t exceed ten perce nt of the
nameplate rat ing , even under sta rtin g cond itio ns.
Low voltages can cause erratic ope rat ion and may
be responsible for seriou s dama ge to the ice
maker.
FOLLOW ALL APP LICABLE CO DES
ELECTRICAL CONNECTIONS
The Scotsma n remote con dense r is designe d to
be powered from the ice machin e. The re is a
separate electrical junctio n box at the back of the
ice maker for the remot e conden ser. Wire the
remote condense r to the ice maker in ac cord ance
with local and natio na l elect ric co de s. All ou tdoo r
wiring must be in rain proo f condu it.
Note: If connecting to another UL listed remote
condenser, follow the instuctions provided with that
product for electrical connect ions.
The condenser fan motor will run whenever the
compressor is running.
Electrical conn ection s are made at the rear of the
ice maker, inside the junction box.
All external wiring should conform to the national,
state and local electrical cod e require ments.
Usually an electrical permit and services of a
licensed electrician will be required .

FOR THE PLUMBER
The recommended wat er supply line is a 3/8-inch
O.D. copper tubin g with a minimum opera tin g
pressure of 20 PSIG and a maximum of 80 PSIG.
Connect to cold wate r sup ply line with st anda rd
plumbing fit tin gs , with shut off valve insta lled in an

required.
Water Limitations:
An ice machine is a food manuf act urin g pla nt , it
takes in a raw material, wate r, and turns it int o a
food product, ice. The purity of the water is very
important in obtaining pure ice and in maximizing
product life. It is generally bett er to filter the water,
although there is no one filter that will cure all
water prob lems. A good filt er co mbin ed with a
polyphosph at e fe eder gives about th e best overa l l
performance .
DRAIN
Connect ion s: A ll drain s are gravit y ty pe an d must
have a minimum of 1/4-inch fall per foot on
horizontal run s. The drain s to be insta lled to
conform with the local plu mbin g code. In stall a
vertical open ve nt on drain line high poin t to insure
good draining . The ideal drain receptac le is a
