Water Spray System - Ice-O-Matic UCG GOURMET Series Installation And Service Manual

UCG GOURMET SERIES UNDERCOUNTER
the size of the cubes. A lower setting will produce a larger cube (oversize) while a higher setting a
smaller cuber (shallow size). When closed on contacts 3‐2 it activates the defrost or harvest cycle
components. The cube size control is set up in the factory (knob in the black dot position) and doesn't
require any adjustment when the ambient temperature remains between 20 and 30 C (70 and 90F).
UCG 135 – 165
The evaporator thermostat with its sensing bulb intimately in contact with the refrigerant outlet tube
from the evaporator senses the evaporating refrigerant temperature (which declines in the course of
the freezing cycle) and when this one reaches the pre‐set value (5°F;-15°C) it switches its contacts from
3‐4 to 3‐2 to activate the finishing cycle (2nd phase) which has a pre‐set extension determined by the
large diameter lobe of the timer.
FAN MOTOR (Air cooled version)
The fan motor on UCG45/65/85/105 is electrically connected in parallel to the water pump and it
operates continuously only during the freezing cycle keeping the proper head press circulating air
through the condenser fins. On UCG135/165 the operation of fan motor is controlled by a fan
pressure control adjusted at preset values. (100-140 psi)
COMPRESSOR
The hermetic compressor is the heart of the refrigerant system and it is used to circulate and retrieve
the refrigerant throughout the entire system. It compresses the low pressure refrigerant vapor causing
its temperature to rise and become high pressure hot vapor (hot gas) which is then released through the
discharge valve.
WATER SPRAY SYSTEM
Through its nozzles it sprays the water in each individual cup to be frozen into ice.
SAFETY HI TEMPERATURE T HERMOSTAT
Located in the control box it is a manual reset switch that trips OFF the operation of the machine when
its bulb (located on the liquid line just before the drier) reaches the temperature of 70C (158F).
CLEANING SWITCH (UCG45/65/85/105 Preset to position 2)
Located on the bottom left side of the control box is used to energize the water inlet and the hot gas
valves so to charge the water into the sump tank of the machine.
