The Gear Reducer
Hydromec mod. V196001 Lifetime synthetic oil
lubrification, no maintenance is required.
Check gear reducer gaskets/oil seals at least
every 2500 hours operation.
Ratio: 1/420
Outlet shaft speed: 3,33 rpm.
The gear reducer is securely bolted on the chassis
base and supports the freezing cylinder as well.
On its input shaft there is fitted the driving pulley.
A separate output shaft with double keys is fitted
in the gear box bore and connected to the auger
shaft via aluminium casting coupling.
The Bin Thermostat Ranco K 22 - L 1075 - must
have its sensing capillary extended into ice room
in a way that it could be contacted by the ice when
storage ice room becomes filled. It terminates ice
production when its capillary gets in contact with
ice. It is wired in series with all other controls. It
is factory set to cut-out at 1,5 °C and cut-in at 4 °C.
The Expansion Valve is FLICA mod. AMVX 3 -
Press 3 bar - Office 4.5 mm for R 404 A - meters
the refrigerant to the evaporator serpentine at 1.7
bar (25 PSI). From s.n. 247 change to Honeywell
TMXV 00110 - Orefice 4,75 MOP - 10°C
Drive Motor Contactor Telemecanique
LC1K09 - with 4 N.O. contacts at 400V 9A with
230V 50-60 Hz coil.
The Evaporator: a vertical stainless steel tube,
refrigerated, and water filled. In it there is a
stainless steel auger and a water seal.
The Auger: a stainless steel triple spiral auger,
it pushes the ice ribbon up to the top of the
evaporator.
The Water Seal: a two part "face" seal, the top
half rotating with the auger, the bottom half
stationary, the sealing action being where the
two seal "faces" meet.
The Breaker: where the ice is compressed and
much of the extra water is squeezed out of it
before it reaches the ice spout.
The Thrust Bearing (Top bearing): as the ice is,
pushed up the evaporator, the auger is thrust
down, and pressure from the auger thrust is
taken up by this bearing.
