Pre-Installation
Other Applications:
Check sales literature for additional information.
Electrical:
Check the nameplate for electrical requirements.
The nameplate is located on the back of the ice
machine. If the information on the nameplate is
different from other published information, go by
the nameplate data.
While the model and
serial number are on
the nameplate, a
serial number plate is
located at the front of
the machine, behind
the left front panel
and to the right of the
purge valve.
Nameplate
Serial Number Plate
Water:
There is no such thing as pure water. All water
contains some impurities. There are two ways
water carries the impurities: suspended and
dissolved. Suspended solids can be filtered out.
Dissolved solids must be diluted or treated. Water
filters are recommended to remove suspended
solids. Some filters have treatment in them for
suspended solids. Check with a water treatment
service for a recommendation.
Cube Ice machines use more water than what
ends up in the bin as ice. While most water is used
during ice making, a portion is designed to “rinse"
out the water system to keep hard water scale
from clogging up the machine. That water rinse,
combined with water filters, prolongs the times
between needed water system cleaning.
Service Technicians: All models covered here
come set from the factory with at a “Standard”
water rinse. Standard water rinse is designed to be
compatible with typical water conditions. The
machine may be adjusted to a different water rinse
after start up. If the prior ice machine worked
acceptably well with the local water conditions,
leave the machine at the factory setting. If severe
water conditions are present, and water filters do
not solve the problem acceptably, adjust the
machine to use more water. If water conditions are
excellent, adjust the machine to use less water.
See the Adjustments section.
Note: Water use adjustments are customer
convenience adjustments; they are NOT factory
defects and are NOT covered by warranty.

freezing compartment.
Cut two lengths of gasket material to fit the right
side top edge of the freezing compartment and
apply them.
4. Place a bead of food grade sealant to the top of
the back wall’s gasket.
5. Place the shield bracket (has a large hole in the
center) from the kit over the center of the freezing
compartment.
Insert the tabs of the bracket into slots on the back
of the unit.
6. Secure bracket at the front with screws from the
kit.
7. Hang the plastic shields from the bracket
installed in the prior step. Use the slots in the
shields to hang them from the stainless steel
hooks.
Note: The notch in the bottom of the shield goes to
the front.
Note: The tabs on the shields must fit inside the
ice outlet port.
8. Check the position of the shields. They must
move freely and be vertical.
Note: The suction line may need to be moved
slightly so the tubing clears the bracket & shields.
9. Place a bead of food grade sealant onto the top
left edge of the freezing compartment.
10. Install the front-to-back support bracket over
the left edge of the freezing compartment.
11. Remove two existing screws and secure the
bracket to the: freezing compartment, back panel
and front channel with the 2 existing screws and 1
large and 4 small screws from the kit.
Both Machines:
12. Place the top ice machine onto the bottom one.
Secure together with hardware from the top
machine. Remove left front and left side panels.
13. At the back of the ice machines, on the
compressor end, remove the upper knock-out from
the bottom machine and the lower knock out from
the upper machine.
14. Place a strain relief (from the kit) into each
hole.
15. Insert wire harness from kit thru strain-relief
and hole in upper corner of the lower ice
machine’s back panel.
NOTE: Harness is marked which end goes to
which machine.
Bottom Machine:
16. Remove harness from controller terminal 7 and
bin thermostat.
17. Route wire harness in lower ice machine to the

For The Installer: Remote Condenser
Locate the condenser as near as possible to the
interior location of the ice maker.
Note: The location of the condenser relative to the
ice machine is LIMITED by the specification on the
following page.
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.
Note: If using any other condenser besides the
ERC411, its use must be approved by
Scotsman, and a head pressure control
valve must be connected to the
condenser coil. The head pressure
valve kit number is: RCKCME6
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.
1. Each set of pre-charged tubing lines contains a
3
“ diameter liquid line, and a
8
1
” diameter
2
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.
3. Route the refrigerant tubes thru 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.
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.
5. Have the roofing contractor seal the holes in the
roof per local codes.

Use the following for planning the placement of
the condenser relative to the ice machine
Location Limits - condenser location must not
exceed ANY of the following limits:
• Maximum rise from the ice machine to the
condenser is 35 physical feet
• Maximum drop from the ice machine to the
condenser is 15 physical feet
• Physical line set maximum length is 100 feet.
• Calculated line set length maximum is 150.
Calculation Formula:
• Drop = dd x 6.6 (dd = distance in feet)
• Rise = rd x 1.7 (rd = distance in feet)
• Horizontal Run = hd x 1 (hd = distance in
feet)
• Calculation: Drop(s) + Rise(s) + Horizontal
Run = dd+rd+hd = Calculated Line Length
Configurations that do NOT meet these
requirements must receive prior written
authorization from Scotsman.
Do NOT:
• Route a line set that rises, then falls, then
rises.
• Route a line set that falls, then rises, then
falls.
Calculation Example 1:
The condenser is to be located 5 feet below the ice
machine and then 20 feet away horizontally.
5 feet x 6.6 = 33. 33 + 20 = 53. This location would
be acceptable
Calculation Example 2:
The condenser is to be located 35 feet above and
then 100 feet away horizontally.
35 x 1.7 = 59.5. 59.5 +100 = 159.5. 159.5 is
greater than the 150 maximum and is NOT
acceptable.
Operating a machine with an unacceptable
configuration will void the refrigeration system
warranty.

Coupling Instructions
The couplings on the ends of the pre-charged line
sets are self-sealing when installed properly.
Follow these instructions carefully.
These steps must be performed by an EPA
Certified Type II or higher technician.
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.
Clean and Lubricate Couplings
3. Position the fittings on the correct connections
on the condenser and ice machine.
1
·
The
“ discharge line (schrader valve end)

goes to the remote condenser fitting marked
“discharge line”.
3
·
The
“ liquid line (schrader valve end) goes to
8
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.
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.
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.
Note: The system charge is contained in the
receiver tank of the ice machine. Only
“holding" charges are present in the
“pre-charged" tubing or the condenser.
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.

3. Use metal box as a template, mark the positions
of 4 holes to be drilled to mount the box to the
condenser.
4. Drill four .157" (#22 or 5/32" bit) dia. holes.
5. Remove plastic covers from the condenser’s
quick connects and those to be used to connect to
the condenser.
6. Thoroughly clean and lubricate the threads and
diaphragms of both the condenser’s and the kit’s
quick connects. Use Polyolester oil.
7. Mount the box to the condenser with the screws
from the kit.
8. Start the swivel nuts by hand.
Use a back up wrench to be certain that the
·
tubing is NOT ROTATING. Only the SWIVEL
NUTS should be rotating!
Then use an adjustable wrench to tighten them
·
until no threads are seen AND a very definite
resistance is felt.
9. Mark the positions of the swivel nuts to the
condenser panel.
10. Rotate the swivel nuts additional one-quarter
turn.
11. Place cover on metal box & secure with screws.
12. Finish the balance of the installation. Ice
machine’s precharged line sets will now connect to
the quick connect fittings on the metal box instead
of the condenser’s.
