3. On R Series Storage Bin inspect its top
mounting gasket which should be flat with no
wrinkles, to provide a good sealing when the
CBT Top Cover is installed on top of it.
4. Place the CBT Top Cover on top of Storage
bin using care not to wrinkle or tear the gasket.
5On the UBH Series Storage Bin unloose
the screws securing the S.S. Top Cover to the
storage bin and remove it
6. Lay out on the bin top the plan of the ice
machine as it will be located on the bin and cut an
opening in the bin top for the ice drop area; cover
the edges of the opening with vinyl tape.
7. Install the gasket-on the bin top-around ice
drop opening of the bin top; apply sealant along
the inside of the gasket.
8. Position and install the four aluminium front
to rear stiffeners (U shaped) paying attention to
the guideline shown on the drawing.
NOTE. Bin wall gasket must be cut to clear
the stiffener ends as shown on drawing.
Do not put any stiffeners crossing the ice
drop opening.
9. Install the bin top in its position onto the bin
top by:
- place the rear side of top against rear edge
of the bin
- lower the front of the top onto the stiffeners
- re-fit the screws previously removed as
per step 5
10. Install the Modular Flaker or Superflaker
onto the Top Cover of storage bin pay attention
to match the ice chute with the Bin Top opening.
D. ELECTRICAL CONNECTIONS
See data plate for current requirements to
determine wire size to be used for electrical
connections. All SIMAG icemakers require
a solid earth wire.
All SIMAG ice machines are supplied from
the factory completely pre-wired and require only
electrical power connections to the wire cord
provided at the rear of the unit.
CBT Top Covers
1. Follow the steps 1 and 2 above to unpack
the top cover.
2. Cut open the carton box and pull out the
CBT Top Cover.
3. On CBT 48/52 FMCD Top Covers, the ice
drop area must be cutted on the plastic cover in
the same position of the ice machine ice chute
opening.
C. LOCATION AND LEVELLING
WARNING. This Modular Flaker and
Superflaker is designed for indoor
installation only. Extended periods of
operation at temperature exceeding the
following limitations will constitute
misuse under the terms of the SIMAG
Manufacturer’s Limited Warranty resulting
in LOSS of warranty coverage.
1. Position the storage bin in the selected
permanent location.
Criteria for selection of location include:
a) Minimum room temperature 10°C (50°F)
and maximum room temperature 40°C (100°F).
b) Water inlet temperatures: minimum 5°C
(40°F) and maximum 35°C (90°F).
c) Well ventilated location for air cooled
models (clean the air cooled condenser at
frequent intervals).
d) Service access: adequate space must be
left for all service connections through the rear of
the ice maker. A minimum clearance of 15 cm
(6") must be left at the sides of the unit for routing
cooling air drawn into and exhausted out of the
compartment to maintain proper condensing
operation of air cooled models.
2. Level the Storage Bin Assy in both the left
to right and front to rear directions by means of
the adjustable legs.

Make sure that the ice machine is connected to
its own circuit and individually fused (see data
plate for fuse size).
The maximum allowable voltage variation should
not exceed -10% and +10% of the data plate
rating. Low voltage can cause faulty functioning
and may be responsible for serious damage to
the overload switch and motor windings.
NOTE. All external wiring should conform to
national, state and local standards and
regulations.
Check voltage on the line and the ice maker’s
data plate before connecting the unit.
E. WATER SUPPLY AND DRAIN
CONNECTIONS
GENERAL
When choosing the water supply for the ice flaker
consideration should be given to:
a) Length of run
b) Water clarity and purity
c) Adequate water supply pressure
Since water is the most important single ingredient
in producting ice you cannot emphasize too
much the three items listed above.
Low water pressure, below 1 bar may cause
malfunction of the ice maker unit.
Water containing excessive minerals will tend to
produce scale build-up on the interior parts of the
water system while too soft water (with too lo
contents of mineral salts), will produce a very
hard flaker ice.
WATER SUPPLY
Connect the 3/4" GAS male of the water inlet
fitting, using the food grade flexible hose supplied
to the cold water supply line with regular plumbing
fitting and a shut-off valve installed in an
accessible position between the water supply
line and the unit.
If water contains a high level of impurities, it is
advisable to consider the installation of an
appropriate water filter or conditioner.
WATER SUPPLY - WATER COOLED MODELS
The water cooled versions of SIMAG Ice
Makers require two separate inlet water supplies,
one for the water making the flaker ice and the
other for the water cooled condenser.
Connect the 3/4" GAS male fitting of the water
inlet, using the flexible hose supplied to the cold
water supply line with regular plumbing fitting
and a shut-off valve installed in an accessible
position between the water supply line and the
unit.
WATER DRAIN
The recommended drain tube is a plastic or
flexible hose with 18 mm (3/4") I.D. which runs to
an open trapped and vented drain. When the
drain is a long run, allow 3 cm pitch per meter
(1/4" pitch per foot).
Install a vertical open vent on drain line high point
at the unit drain connection to ensure good
draining.
The ideal drain receptacle is a trapped and vented
floor drain.
WATER DRAIN - WATER COOLED MODELS
Connect the 3/4" GAS male fitting of the condenser
water drain, utilizing a second flexible hose to the
open trapped and vented drain.
This additional drain line must not interconnect to
any other of the units drains.
NOTE. The water supply and the water drain
must be installed to conform with the local
code. In some case a licensed plumber and/
or a plumbing permit is required.
F. FINAL CHECK LIST
1. Is the unit in a room where ambient
temperatures are within a minimum of 10° C (50°F)
even in winter months?
2. Is there at least a 15 cm (6") clearance
around the unit for proper air circulation?
3. Is the unit level? (IMPORTANT)
4. Have all the electrical and plumbing
connections been made, and is the water supply
shut-off valve open?
5. Has the voltage been tested and checked
against the data plate rating?
6. Has the water supply pressure been checked
to ensure a water pressure of at least 1 bar (14
psi).
7. Have the bolts holding the compressor down
been checked to ensure that the compressor is
snugly fitted onto the mounting pads?
8. Check all refrigerant lines and conduit lines
to guard against vibrations and possible failure.
9. Have the bin liner and cabinet been wiped
clean?
10. Has the owner/user been given the User
Manual and been instructed on the importance of
periodic maintenance checks?
11. Has the Manufacturer’s registration card
been filled in properly? Check for correct model

WARNING. This icemaker is not designed for outdoor installation and will not function in
ambient temperatures below 10°C (50°F) or above 40°C (100°F).
This icemaker will malfunction with water temperatures below 5 °C (40°F) or above 35 °C
(90°F).

OPERATING INSTRUCTIONS
START UP
After having correctly installed the ice maker and
completed the plumbing and electrical
connections, perform the following “Start-up” pro-
cedure.
A. Open the water supply line shutoff valve
and put the unit under electrical power by moving
the main switch, on the power supply line, to the
ON position.
The first LED - GREEN - will glow to signal that
unit is under power.
NOTE. Every time the unit is put under power,
after being kept for sometime in shut-off
conditions (electrically disconnected) the
RED LED will blink for 3 minutes (60' on SPN
1205 only) after which the unit will start up with
the immediate operation of the gear motor
assembly and, after few seconds, of the
compressor (Fig.1).
B. Elapsed the stand by period the unit starts
operating with the activation in sequence of the
following assemblies:
GEAR MOTOR/S
COMPRESSOR
FAN MOTOR/S (if unit is an air cooled version)
kept under control by the condenser temperatu-
re sensor which has its probe within the condenser
fins (Fig.2).
C. After 2 or 3 minutes from the compressor
start up, observe that flaker ice begins dropping
off the ice spout to fall through the ice chute into
the storage bin.
NOTE. The first ice bits that drop into the ice
storage bin are not so hard as the evaporating
temperature has not yet reached the correct
operating value. It is necessary to allow the
ice - just made - to cure itself and wait for
about ten minutes for the evaporating tem-
perature to reach the correct value so to
make more hard bits of ice.

NOTE. If, after ten minutes from the
compressor start-up, the evaporating tem-
perature has not dropped down to a value
lower than -1 ° C (30 ° F) the evaporating tem-
perature sensor detects such an abnormal
situation and stops consequently the unit
operation (first the compressor and 3' later
the gear reducer).
In this circustance, the 5th warning YELLOW
LED will blink.
The machine will remain in OFF mode for
one hour then it will restart automatically.
In case the unit trips OFF again in alarm for
3 times in 3 hours, the machine SHUTS OFF
DEFINITIVELY.
After having diagnosed and eliminated the
cause of the too hi evaporating temperature
(insufficient refrigerant in the system or
compressor not running) it is necessary to
unplug and plug in again to restart the
machine. The unit, before resuming the
normal operation, will go through the usual
3 minutes STAND-BY period.
OPERATION CHECKS UPON THE UNIT
START UP
D. Remove front service panel and, if
necessary, install the refrigerant service gauges
on the corresponding service valves to check
both the HI and LO refrigerant pressures.
NOTE. On air cooled models, the condenser
temperature sensor, which is located within
the condenser fins, keeps the head
(condensing) pressure between preset
values.
In the event of condenser clogged - such to
prevent the proper flow of the cooling air - or,
in case the fan motor is out of operation, the
condenser temperature rises and when it
reaches 70 ° C (160 ° F) for air cooled version -
and 60 ° C (140 ° F) - for water cooled version -
the condenser temperature sensor shuts-off
the ice maker (first the compressor and 3'
later the gear reducer) with the consequent
light-up of the RED WARNING LIGHT (Fig.3).
The machine will remain in OFF mode for
one hour then it will restart automatically.
In case the unit trips OFF again in alarm for
3 times in 3 hours, the machine SHUTS OFF
DEFINITIVELY.
After having diagnosed the reason of the
temperature rise and removed its cause, it is
necessary to proceed as per the previous
“NOTE” to start up again the operation of the
ice maker.
E. Check for the correct CUT-OUT and
CUT-IN of the water level sensor by first shutting
closed the water shutoff valve on the water
supply line.
