1. HOW IT WORKS

The system is very simple and efficient. The evaporator is built up connecting together a series of
reversed cups with a cooling coil. The refrigerant flows into the tubes while the pump sprays water
into the cups. Thus inside each cup, an ice cube grows layer by layer.
When the cubes are ready, harvest starts : hot gas flows through cooling coil of the evaporator and
fresh water enters on top of evaporator. This melts the outer surface of the cubes which fall into the
bin.
A new freezing cycle then begins.
When the bin is full of ice, the unit stops production. When a quantity of ice is taken away, the unit
restarts production.

PAG.2

1.A.a. Freezing cycle

1. The compressor C pumps the refrigerant to the condenser CD or CA when the hot gas valve

VG

is closed.

2. The liquid line reaches the evaporator E through the molecular sieve F and the capillary tube T.

3. In the evaporator the refrigerant expands, thus producing the freezing effect.

4. The refrigerant goes back to the compressor through the receiver/tank B and suction line/heat
exchanger S.

5. The freezing cycle ends when the evaporator thermostat TE reaches the set temperature thus
starting the TIMER; when the time is over, the refrigeration cycle ends and the VG hot gas
valve is opened.

1.A.b. Defrost cycle (harvest)

1. When the hot gas valve VG open, refrigerant flows directly from the compressor C to the
evaporator E and back to the compressor through S.

2. Duration of harvest is fixed by the timer. There is a delay in starting the TIMER in the defrost
period. The TIMER is energized when the evaporator thermostat TE reaches the preset high
'IN' temperature; for this reason the motor of the TIMER is connected directly with the
COMMON contact of the evaporator thermostat. When the harvest ends, the timer is de­energized, the hot gas valve VG is closed and a new freezing cycle begins.

1.A.c. Air cooling

1. Models with air cooled condenser, have a fan motor V which is always energized (mod. CP30,
CP45) or is switched on and off by the pressure switch PT, (mod.CP70, CP120) which senses
condensing pressure.

2. Pressure switch PT is factory set. After sale service is

not allowed

to make adjustments for any

reason.

1.A.d. Water cooling

1. Models with water cooled condenser, have a fan motor V which is always energized.

2. Water inlet to condenser is regulated by the pressure switch PT, which senses condensing
pressure and energizes or not the condenser water inlet solenoid valve VC.

3. The safety thermostat

TSA

feels condensing temperature, too. In case of excessive temperature,
due e.g. to water shortage, valve failure etc., it shuts down the unit. When temperatures
decreases, it starts again.

4. Condenser thermostats and pressure switch are factory set. After sale service is

not allowed

to

make adjustments for any reason.

1. The pump P takes water from the water tank WT through a suction pipe and sends it to the
spray bar SB (two pumps and two spray bars for mod. CP120).

2. The water sprayed by the nozzles reaches the cooled cups on the evaporator E. A quantity of
water freezes and the excess falls again into the water tank.

3. The water inlet valve VA is closed.

1.B.b. Defrost cycle (harvest)

1. The water inlet valve VA is open. Fresh water goes up on top of evaporator, helping defrost.

2. From the top of the evaporator, water falls into the water tank and refills it.

3. Excess water is discharged by the overflow control OF.

4. Water pump(s) is not working.

2. INSTALLATION

2.A. CONNECTIONS

1. Choose a location far from heating sources and in a well ventilated dry place, not dusty, near

water inlet & drain connections.

2. Provide enough clearance at both sides and at rear of the unit (20 cm at least).

DO NOT USE UNIT OUTSIDE AND DO NOT EXPOSE IT TO RAIN.

3. Set upstream of the units an electrical multi-pole disconnect switch having a contact separation

of at least 3 mm in all poles. Switch rating shall comply with power specifications of each ice­maker, as per specifications given in the plate on rear of each unit.

ALL CONNECTIONS SHOULD BE MADE IN ACCORDANCE WITH EXISTING

LOCAL ELECTRICAL REQUIREMENTS.

4. Power supply must match voltage specifications on registration plate on rear of unit. +/- 6%

deviation permitted. On higher rushes no assurance of correct operation is given.

5. Water inlet should be regulated by a 3/4" threaded tap, for an easy installation of the supply hose.

ATTENTION! CONNECT UNIT TO DRINKING (POTABLE) WATER ONLY.

6. Check if water inlet pressure is between 1 to 3 bar. If it is higher, install a pressure reducer set at

2,5 bar.

7. Water outlet must be at ground level connected to an open vented siphon.

2.B. SET-UP

2.B.a. AIR COOLED CONDENSER UNITS

1. Unpack the ice maker without turning the unit upside down, check for damage, remove all

cartons and the wooden pallet.

2. Remove the bag with the accessories from inside the unit. Take care of the Final User Manual

and give it to your customer. Remove the water blinds assembly. Check that the water spray-bar
and the internal ice chute are in the correct position, then re-install water blinds assembly.

3. Connect the unit to the external multi-pole switch for electric supply.

4. Check that the unit is perfectly level. If required, adjust leveling feet.

5. Connect the water inlet solenoid valve to the water mains tap with the rubber water supply tube.

6. Connect a drain hose to the water outlet of the unit and the open vented siphon at floor level.

7. Clean walls and bottom of storage bin with a wet cloth.

8. Open tap on water mains and check for leakage.

9. Switch on main external disconnect switch.

10. The unit starts in defrost at first installation. Water is charged and fills water tank. When the

timer ends the defrost cycle, the freezing cycle begins.

11. After a shut-off period, it is possible that the unit will not re-start in defrost. In this case or in

case more water is needed, turn clockwise the orange pin of the timer with a screwdriver, until
the unit goes in defrost.

12. Always charge fresh water before starting ice production, at first installation and after a long

shut-off period.

To start and stop unit, only use the external disconnect multi-pole switch.

3. START-UP & TEST

When all the installation procedures have been completed, and all panels that should have been
removed, have been replaced in position, you can start-up the unit.

3.A. START-UP

1. Clean walls and bottom of storage bin with a wet cloth.

If needed, follow instructions for sanitizing the storage bin and/or the ice-maker.

2. Open tap on water mains and check for leakage.

Always charge water before starting ice production at first installation, or after a shut-off period.

3. Ambient temperature must range 10°C to 43°C .

Water temperature must be between 10°C and 25°C.

4. Switch main external disconnect switch on.

To switch unit ON and OFF operate on the external disconnect switch only.

5. Unit starts production.

Within half an hour the first ice cubes will fall into the storage bin.

6. For best performance, we suggest that ambient temperature should be between 12°C and 38°C.

F.A.G. SRL

SELF CONTAINED UNITS WITH TIMER

ME-CPT1-199 COMPACT SERVICE MANUAL

PAG.11

3.B. TEST

1. Wait three producing cycles before making any adjustment, then check the ice cubes. They must

have a small dimple. If they are too empty, turn the adjusting screw of the ice-control thermostat
clockwise to '+'. If they are too full, turn the screw counter clockwise to '-'.

2. Always make slight adjustments and wait for results. Do not insist on obtaining a full cube

without any dimple by adjusting the evaporator thermostat (ice-control) to full '+'.
Especially with hot external temperatures, adjusting the evaporator thermostat (ice-control) to
full '+' will cause the unit to have very long producing cycles, with a great decrease in production.
It is also possible that too full cubes won't fall into the bin during the defrost cycle and so they
will be cut and melted by water spray, obtaining the opposite of what thought.

3. If cubes are white or not complete, clean spray bar and nozzles.

4. With ice in contact with the ice bin level feeler inside the bin, the unit should stop within 1 min.

If not, slightly turn the adjusting screw of the bin thermostat counter clockwise towards
'SUMMER' until the unit stops. With the feeler cleared from ice, the unit should restart within 5
min. If not, screw slightly clockwise towards 'WINTER'.

5. To reach thermostats or Timer remove front panel.

6. Final User is not allowed to change adjustments of the thermostats or to service unit.

With water and/or ambient temperature below 10°C, to help ice cubes fall into the bin, it is possible
to increase duration of harvesting operating on the adjustable cam of the TIMER.

Timer

To change duration of harvest cycle, loosen the lock
screw releasing the moving cam.
Change position of the cam referring to the numbers
printed on the orange part.
Lock the cam with the screw.

When you re-assemble all the parts removed for cleaning, it is very important to verify that the
nozzles are free to spray water and that the ice chute does not interfere with the spray bar. (nozzle
must be in the middle of the rows of the ice chute fig 4.B.3).

fig 4.B.3

4.B.b. Sanitizing - To remove algae or slime

1. To sanitize ice storage bin, take away all the ice and gently wipe walls and bottom of the bin with

a cloth and a sanitizing cleaner following the directions of the manufacturer of the product.
You can use household products or a diluted solution of sodium hypoclorite (bleach).

2. To sanitize water tank and all the water system, follow instructions for cleaning using a sanitizing

product instead of a cleaner.

If your water is rich in chlorine, you will not obtain a full clear and crystal ice-cube, and the ice will
melt sooner.

It may be necessary to connect water supply to a water treatment system to inhibit scale formation,
filter sediment or remove chlorine taste.

Water treatment will pay for itself through decreased maintenance, higher efficiency and quality of
product.
