The DIP SWITCH N° 7 and 8 allow the extention
of the length of the harvest/defrost cycle according
to their combination as per following chart:
DIP SWITCH ADDITIONAL DEFROST TIME
78
ON ON 0
OFF ON 30"
ON OFF 60"
With both DIP SWITCH 7 & 8 in OFF position, Water
Pump is OFF during the Harvest Cycle with no additional
time.
The 9th key is used to supply power to the water
pump for the first 15 seconds of the defrost cycle
- position OFF - or for the first 30 seconds -
position ON.
The 10th key is used to modify the CUT-OUT
condensing temperature from 70°C (160°F) for
the air cooled versions - ON position - to 60°C
(140°F) - OFF position - for the water cooled
versions.
I. CONDENSER AIR FILTER
(Air cooled version)
Located in front of the air cooled condenser can
be removed by withdrawing it through the opening
of the front panel for cleaning or replacing. A
lower plastic guide, installed inside the unit, is
used for the correct sliding and location of the air
filter.
L. WATER SPRAY SYSTEM
Through its nozzles, the water pumped, is sprayed
in each individual cup to be frozen into ice.
It consists of one spray tube wheve are located
several spray nozzles.
M. WATER PUMP
The water pump operates continually throughout
the freezing cycle and on the first 15 or 30
seconds of the defrost cycle so to such the
remaining water from the sump tank (reach in
mineral salts) and drain it out. During the freezing
cycle the pump primes the water from the sump
to the spray system and through the spray nozzles
sprays it into the inverted cup molds to be frozen
into crystal clear ice cubes. It is recommended
that the pump motor bearings be checked at
least every six months.
N. WATER INLET SOLENOID VALVE -
3/4 MALE FITTING
The water inlet solenoid valve is activated by the
micro processor of the P.C. BOARD during the
first 5 minutes of water filling phase as well as
during the defrost cycle. When energized it allows
a metered amount of incoming water to flow over
the evaporator cavity to assist the hot gas in
defrosting the ice cubes. The water running over
the evaporator cavity drops by gravity, through
the dribbler holes of the platen, into the sump
reservoir where it will be sucked by the water
pump and primed to the spray system.
