1 Approved De-scaler & Sanitizer
FREQUENCE
•Cleaning: Every six months
•Sanitizing: Every month
NOTE. THE FOLLOWING PROCEDURE CAN BE
USED FOR EITHER SANITIZING OR DE-SCALING
THE ICE MACHINE.
NEVER MIX THE SANITIZING SOLUTION WITH THE
DE -SCALING SOLUTION.
IN CASE THE MACHINE NEEDS TO BE SANITISED
AND DE-SCALED, CLEAN THE MACHINE
THOROUGHLY, THEN FIRST DE-SCALE, AND AFTER
PROPER WASHING AND RINSING, DO THE
SANITATION.
WARNING. When using any chemical, protection of
hands and eyes should be worn.
NOTE. De-scaling is recommended every 6 months in
average water hardness conditions, while sanitizing
should take place once a month. Under extreme water
hardness conditions we recommend to de-scale every
two – three months, and to sanitize every two weeks.
Sanitizing regularly will reduce bacteria growth, which is
natural in all water circulation systems as ice machines.
NOTE. Always follow approved Sanitizer / De-scaler
manufacturers instructions when preparing the Sanitizer
/De Scaler solutions.
