ICE MAKING SEQUENCE
Your TRUE Ice
®
machine will produce one batch of
ice (24 cubes) approximately every 20 minutes. The
following steps occur during ice making–
INITIAL FILL / INITIAL HARVEST
The ice machine always begins in Fill mode.
During Fill or Harvest modes–
• The display will read
FiL
(Fill mode) or
hAr
(Harvest mode).
• The reservoir fills with water (for 2–3 minutes)
• Excess / residual water drains.
• Any residual ice cubes from a previous cycle are
melted free from the evaporator by warming the
evaporator with a warm refrigerant (Harvest mode).
ICE MAKING
When making ice–
• The display will read
ICE
• Water sprays into the inverted ice cups as the
evaporator cools, forming ultra-clear ice cubes in
each cup
• The compressor, condenser fan motor, and water
pump operate.
• As ice is produced on the evaporator, the reservoir's
water level will lower.
• Adjusting the ice cube size alters the water level
needed for completing the cycle.
• The ice making cycle ends when
○
The reservoir's water level has dropped to a
sufficient level based on the ice cube size
setting OR
○ When the t1 evaporator probe detects the
minimum temperature threshold.
ICE HARVEST
When harvesting ice–
• The display will read
hAr
• The compressor remains on, but the condenser fan
motor and pump turn off. The hot gas bypass and
water valves open.
• As the evaporator warms, ice cubes begin to fall
into the ice bin.
• The reservoir refills with water and overflows to
flush impurities down to the drain pump.
• The harvest cycle ends when the evaporator
reaches 47˚F (8.3˚C) and then a completion
timer expires.
• All 24 ice cubes should fall into the ice storage bin
before the next ice making cycle begins.
FULL BIN
When the ice bin is full–
• The display will read FUL
• The ice machine shuts off automatically when the
ice level sensor determines the amount of ice has
reached the set level (see "Adjust Ice Level",
page 39).
• The condenser fan will turn on in reverse to clean
the condenser; this removes any built-up dust or
debris, which prolongs the time needed between
full condenser coil cleanings.
• The drain pump will periodically run to remove any
residual water in the bin from melted ice cubes.
• The ice machine turns back on when the ice level
sensor determines the amount of ice has decreased
to below the set level (see "Adjust Ice Level",
page 39).
