ICE MAKER CLEANING & MAINTENANCE
Cleaning and maintenance should be performed a minimum of every six months (see the Recommended Cleaning /
Maintenance Schedule below). Basic cleaning and maintenance of the ice machine will increase its reliability,
enhance its performance, and help save on water and power consumption.
NOTES:
• Some water conditions will dictate more frequent cleaning of the ice making section, just as some carpets and pets
will dictate more frequent cleaning of the condenser.
• To ensure efficient operation, Sub-Zero recommends an annual cleaning be performed by a qualified service tech-
nician in which the ice machine is partially disassembled for a more thorough cleaning and sanitizing.
M aintenance Event
Clean cabinet exterior
Clean and sanitize interior
Replace water filter*
Clean condenser coil
Check ice quality
* Poor water quality may require more frequent cleaning, sanitizing and water filter replacements.

Cleaning the Exterior

Begin cleaning the exterior with mild soap and warm
water on a sponge to remove any dust and dirt (this
includes the door and door gasket). Wipe dry with a
clean, soft cloth. When cleaning stainless steel, use
cleaners designed for use with stainless steel products.
Never use plain steel wool or abrasive pads, as they
will scratch the panels.

Cleaning the Condenser

The condenser is located at the right side of the com-
pressor area, behind the kickplate and it looks similar to
the radiator on a car. To clean the condenser, follow
the directions below:
DISCONNECT ELECTRICAL POWER TO ICE
MACHINE AT THE ELECTRICAL SERVICE SWITCH-
ES BEFORE CLEANING THE CONDENSER.
1. Extract four bolts holding kickplate and pull it for-
ward (clean kickplate openings before replacing).

2. With a brush attachment, vacuum face of condens-
er while moving the brush up and down. (See
Figure 4-1)
Do not bend the metal fins of the condenser, doing
so will restrict airflow through the condenser, pos-
sibly causing mechanical failure of the ice maker.
