ELEVATION SERIES CIM CUBER

EVAPORATOR

Evaporator Assembly
The nickel plated Evaporator Assembly has a
copper core to assure good heat transfer.
Water is pumped gently over the Evaporator
during the freeze cycle for even ice formation.
Evaporator Operation
The Evaporator should be fully flooded with refrigerant for most of the freeze cycle to assure
even ice formation. The serpentine on the back of the Evaporator starts at the bottom right
corner of the plate (viewed from the front). The refrigerant lines run horizontally back and forth
to the middle of the plate then rise along the left hand side to the top. The lines continue "ser‐
pentining" downward to the middle of the plate and exit the Evaporator.
Troubleshooting
The Evaporator should always have a nickel appearance. Should the Evaporator have a "rust"
color after a thorough cleaning, the plating may have come off and a replacement may be
required. A dull "rainbow shimmer" may indicate an improper cleaner was used on the unit.
Only approved Nickel Safe ice machine cleaner should be used.
An improper ice formation can be caused by a water or refrigeration issue.
A dirty water system can cause poor water flow over the Evaporator resulting in improper ice
formation. See pg 56 for Cleaning Instructions.
A refrigeration issue such as a low charge or restricted TXV could show on the Evaporator as ice
forming on the bottom of the plate with thin to no ice forming on the top half. Verify refrigera‐
tion pressures on the Technical Specifications chart on pg. 60.
Should the ice slab resist coming off the plate, examine the Evaporator for lose of plating,
pitting, mineral accumulation and/or loose horizontal dividers. Should any of the horizontal
dividers separate from the base, replacement of the Evaporator is recommended.
