Location & Assembly
Locate the ice machine indoors. Locate the remote
condenser as close as possible to the ice machine. The
best location for the condenser is above the ice machine.
Unpacking and Assembly:
Begin with unpacking the ice storage bin. Remove the
carton, and using part of the carton as a cushion, tip the
bin on its back to remove the skid and attach the legs or
casters.
Note: Stacked applications may not use casters.
Return the bin to an upright position. Check the bin top
gasket for gaps and tears, fill any in with food grade
sealant prior to placing the ice machine on the bin.
Level the top edge of the bin front to back and left to
right.
If the ice machine has not been unpacked, do so now.
Remove the carton from the skid. After removal of the
shipping straps, lift the ice machine off the skid directly
onto the bin.
Note: The machine is heavy! Use a mechanical hoist if
necessary.
Secure the ice machine to the bin with the hardware
provided (two metal straps and 4 bolts).

Remote System Installation
Information:
Use precharged tubing kits, RTE25 (25’) or RTE40 (40’)
or RTE75 (75’). Select the length closest to the needs of
the particular installation.
For The Installer: Remote Condenser
3. Route the refrigerant tubes through the roof opening. Follow
straight line routing whenever possible.
Note: Excess tubing may EITHER be coiled up INSIDE the
building OR cut out prior to connection to the ice maker and
condenser.
If the excess tubing is cut out, after re-brazing the tubing must
be evacuated prior to connection to the ice maker or condenser.
Locate the condenser as near as possible to the interior
location of the ice maker.
Note: The recommended location of the condenser is
above the ice machine.
Select the best available location, one that protects the
condenser from extremes of dust, grease and sun.
Meet all applicable building codes.
Roof Attachment
Install and attach the remote condenser to the roof of the
building, using the methods and practices of
construction that conform to the local building codes,
including having a roofing contractor secure the
condenser to the roof.
The only remote condenser for the CME1356R and
CME1656R ice machines is Scotsman’s ERC411.
The only remote condenser for the CME1056R ice
machine is Scotsman’s ERC311.
Precharged Line Routing
Do not connect the precharged tubing until all routing
and forming of the tubing is complete. See the Coupling
Instructions for final connections.
If the excess tubing is to be coiled, spiral it horizontally to avoid
excess trapping in the lines.
Note: A 36" service loop may be placed behind the ice machine.
4. Have the roofing contractor seal the holes in the roof per
local codes.

Building
1. Each set of pre-charged tubing lines contains a
smaller diameter liquid line, and a larger diameter
discharge line. Both ends of each line have quick
connect couplings, the end without access valves goes to
the ice maker.
Note: The openings in the building ceiling or wall, listed
in the next step, are the minimum sizes recommended
for passing the refrigerant lines through.
2. Have the roofing contractor cut a minimum hole for
the refrigerant lines of 2". Check local codes, a separate
hole may be required for the electrical power supply to
the condenser.
Caution: Do NOT kink the refrigerant tubing while
routing it.
7
Coupling Instructions
The couplings on the ends of the pre-charged line sets
are self-sealing when installed properly. Follow these
instructions carefully.
Initial Connections
1. Remove the protector caps and plugs. Wipe the seats
and threaded surfaces with a clean cloth to remove any
possible foreign matter.
2. Thoroughly lubricate the threads, o-rings, diaphragms
and all internal coupling surfaces with polyolester
refrigerant oil.
4b. Using two wrenches, one to rotate the swivel nut and one to
hold the tubing in place, tighten each coupling.
Tighten Swivel Nut
It is CRITICAL that ONLY the NUT on the pre-charged tube
be turned, or the diaphragms will be torn by the piercing knives
and become loose in the refrigeration system causing severe
operational problems.
Note: As the coupling is tightened, the diaphragms in the quick
connect couplings will begin to be pierced. As that happens,
there will be increased resistance to tightening the swivel nut.
Clean and Lubricate Couplings
3. Position the fittings on the correct connections on the
condenser and ice machine.
The discharge line (schrader valve end) goes to the
remote condenser fitting marked “discharge line".
The liquid line (schrader valve end) goes to the remote
condenser fitting marked “liquid line".
The discharge line goes to the ice maker fitting marked
“discharge line".
The liquid line goes to the ice maker fitting marked
“liquid line".
Final Connections:
4a. Begin to tighten the couplings together by hand.
Continue to turn the swivel nuts by hand until it is
certain that the threads are properly engaged.
4c. Continue tightening the swivel nut until it bottoms out or a
very definite increase in resistance is felt (no threads should be
showing). Do NOT overtighten.
5. Use a marker or pen to mark a line on the coupling nut and
unit panel. Then tighten the coupling nut an additional
one-quarter turn. The line will show the amount that the nut
turns.
Rotate Swivel Nut ¼ Turn More
6. After all connections have been made, and after the liquid
line valve has been opened (do not open yet), check the
couplings for leaks.

Plumbing
machine, do NOT assume that the water flow capacity of the
filter will be adequate.
All models require an adequate potable water supply and
a gravity drain. The recommendations for tubing are:
Water supply to be 3/8" OD.
Drain to be 3/4" OD.
Supply:
There is one water supply connection, a 3/8" male flare
at the back of the cabinet. Connect to cold potable water
that has adequate pressure.
Note: Using water supply tubing smaller than 3/8" will
cause severe operational issues.
Water Filters:
The water filters must flow at least 10 liters per minute
or they will cause severe operational issues. Check with
the filter manufacturer. When replacing a prior ice
All Drain Tubing Material must be RIGID. Flexible tubing will
eventually cause a restricted drain.
Drain:
There is one gravity drain connection, a 3/4" FPT fitting at the
back of the cabinet. Use only RIGID TUBING. Flexible tubing
may be easily kinked or become cracked.
The drain tube must be vented at the back of the cabinet. Use a
45 cm high vent.
The drain for the ice machine and the ice storage bin must be
SEPARATE or the ice machine’s drain water may run into the
bin and MELT THE ICE.
Insulation is recommended for the ice machine reservoir and bin
drains.

Component Description and
Function
Harvest Bypass Valve: Injects additional refrigerant into
the harvest system.
when warmed up during the harvest cycle. The freezing
compartment is fully insulated for maximum efficiency.
Cube Deflectors: The slots in the inclined deflectors let the
water falling from the evaporators back into the reservoir, but
when ice falls during harvest, the ice slides off into the bin.
Check Valves: Liquid and Discharge lines contain check
valves. These control refrigerant migration during the
Harvest and Off cycles.
Reservoir: Contains the water for ice making.
Water Inlet Valve: Opens to allow water into the
reservoir.
Water Level Sensor: Controls the size of the ice cube by
measuring how much water is used in a cycle. It consists
of a float, stem and electric eye. The stem will move
slightly when the pump is on, this is normal. As the
machine makes ice the reservoir water level will fall and
the visible portion of the stem will slide down through
the slot in the sensor body.
Evaporators/Freezing Compartment: Location of the
evaporators. Ice forms on the evaporators and is released
Head Pressure
Control Valve
Refrigeration Service Access Valves: Only to be used by a
certified technician. Allows access to the refrigeration system
for diagnostic information.
Water Pump: Forces the water from the reservoir to the top of
the evaporators. The motor is separated from the reservoir water
to minimize contact with the water.
Hot Gas Valve: Closed during freeze, it opens during harvest to
divert hot discharge refrigerant gas into the inlet of the
evaporators.
Purge Valve: Opens during the early part of the harvest cycle to
drain the reservoir.

Montage sur le toit
Installer et fixer le condenseur à distance sur le toit du
bâtiment, suivant les méthodes de construction qui
satisfont la réglementation locale en vigueur, en faisant
notamment assujettir le condenseur par un couvreur.
Le modèle ERC411 de Scotsman est le seul condenseur
à distance qui convient aux machines à glaçons
CME1356R et CME1656R.
Quant à la machine à glaçons CME1056R, elle demande
le modèle ERC311 de Scotsman.
Acheminement des tuyaux préchargés
Ne pas brancher les tuyaux préchargés avant de les avoir
complètement acheminés et mis en place. Le
raccordement final fait l’objet des “Instructions de
raccordement”.
Si l’on décide d’enrouler la tuyauterie en excès, faire des
spirales à l’horizontale pour éviter de trop ralentir le débit.
Note : Une boucle de service de 91 cm peut être dissimulée
derrière la machine.
4. Faire colmater les trous par le couvreur, conformément à la
réglementation locale.

1. Chaque jeu de conduites préchargées comporte deux
conduites : une à petit diamètre pour le liquide et l’autre
plus grosse pour l’évacuation. Les deux conduites se
terminent aux deux bouts par des raccords instantanés, le
côté sans vanne d’accès se branchant sur la machine à
glaçons.
Note : Les ouvertures qu’il est demandé de pratiquer au
plafond ou dans le mur à l’étape suivante correspondent
au minimum requis pour faire passer les conduites de
réfrigérant.
2. Demander au couvreur de découper un trou minimum
de 51 mm de diamètre à l’intention des conduites de
réfrigérant. Se renseigner sur la réglementation locale
car un trou séparé peut être requis pour l’alimentation
électrique du condenseur.

Instructions de raccordement
À condition d’être mis correctement en place, les
raccords dont sont munies les extrémités des jeux de
conduites préchargées sont auto-étanchéifiants. Suivre
soigneusement les présentes instructions.
Raccordement initial
1. Enlever les capuchons protecteurs et obturateurs.
Essuyer les sièges et les surfaces filetées avec un chiffon
propre pour éliminer les corps étrangers éventuels.
2. Soigneusement lubrifier les filetages, joints toriques,
membranes et toutes les surfaces d’accouplement
4b. Serrer chaque raccord à l’aide de deux clés, une pour
l’écrou-raccord, l’autre pour maintenir la tuyauterie en place.
Serrer l’écrou-raccord
Il est ESSENTIEL de tourner UNIQUEMENT l’ÉCROU du
tuyau préchargé, sinon les membranes seront déchiquetées par
les couteaux de perçage et iront se perdre dans le circuit de
réfrigération, d’où graves problèmes de fonctionnement.
Note : À mesure du serrage, les membranes des raccords
instantanés commenceront à être percées. Ceci se traduit par
une résistance accrue au serrage de l’écrou-raccord.
Nettoyer et lubrifier les raccords
internes avec de l’huile réfrigérante polyolester.
3. Positionner les raccords aux emplacements
correspondants sur le condenseur et la machine à
glaçons.
La conduite d’évacuation (côté vanne Schrader) doit être
branchée dans le raccord marqué “discharge line" du
condenseur à distance.
La conduite de liquide (côté vanne Schrader) doit être
branchée dans le raccord marqué “liquid line" du
condenseur à distance.
L’autre bout de la conduite d’évacuation est destiné au
raccord marqué “discharge line" de la machine à
glaçons.
L’autre bout de la conduite de liquide est destiné au
raccord marqué “liquid line" de la machine à glaçons.
Raccordement final :
4a. Commencer par serrer les raccords à la main.
Continuer à visser manuellement les écrous-raccords
jusqu’à ce que l’on soit sûr de l’engagement correct de
leurs filets.
4c. Continuer à serrer l’écrou-raccord jusqu’à ce qu’il arrive à
fond ou qu’une résistance nettement accrue se fasse sentir (il ne
devrait plus y avoir de filet visible). Ne PAS serrer à outrance.
5. Tracer au crayon marqueur ou autre un repère sur
l’écrou-raccord et le panneau de l’unité. Puis donner un quart de
tour supplémentaire à l’écrou-raccord. Le repère montre la
quantité de rotation de l’écrou.
Donner ¼ de tour suppl. à l’écrou-raccord
6. Une fois tous les branchements effectués et le robinet de la
conduite de liquide ouvert (ne pas l’ouvrir tout de suite), vérifier
l’étanchéité des raccords.
