PREP – CLEANING PROCEDURE
Use ice machine cleaner on a coarse-surface cloth material (such as terry cloth) and wipe down the in-
side wall of the evaporator area, the water pan, the water curtain and the plastic water deflector. If the
water distributor tube has heavy scale build-up, remove and soak it in full-strength nickel safe ice ma-
chine cleaner (or exchange the tube and clean the scaled tube at a later date) (See Figure 6).

Cleaning the Water System and Evaporator

1. Turn the power switch to "OFF".

The cleaner will drain into the water pan.

5. Return the water curtain(s) to their proper operating positions.
6. Add "Calgon Nickel Safe" ice machine cleaner directly into the water pan (green only):
S 5 oz. for the 300's,
S 8 oz. for the 500's, 600's, and 800's,
S 12 oz. for the Dual Evaporator, and
S 16 oz. for the Quad.
7. Turn the power switch to "ON" , allow the compressor to start, and depress the clean button two
times on the front of the electrical box.
8. The unit will run through a fifteen (15) minute cleaning cycle, which includes 3 rinse cycles.
9. Once the cleaning cycle finishes, the error LED will flash 8 times.
10. When the clean cycle is complete, turn the power switch to "OFF" for five (5) seconds, then to "ON".
The unit will return to normal operating mode. Discard the first batch of ice produced.
NOTE: Ice machines should only be cleaned when needed, not by a timed schedule of every 60
days, etc. Should your ice machine require cleaning more than twice a year, consult your distrib-
utor or dealer about proper water treatment.
