using ScaleFree™ or Distilled White Vinegar
ScaleFree™ Descaling Compound is an acid-based descaler combined with a proprietary chelating
agent that is effective in dissolving and removing carbonate, lime-scale and iron scale build-up
caused by hard water. ScaleFree efficiently and effectively removes lime-scale build-up from combi
ovens.
ScaleFree™ is a non-hazardous, Biodegradable Citrus Based Powder that when mixed with water
becomes a powerful lime-scale remover.
It is VERY important to decalcify the oven, particularly in areas with extremely hard water.
PERFORM ONCE A MONTH in addition to the daily steam generator flush.
WITH THE OVEN AT ROOM TEMPERATURE
1. Begin decalcification with the power
knob in the OFF position.
2. Open oven door. Wearing hand
protection, rotate the Steam Generator
Drain Cap ቨ until water begins to flow
from the four holes in the cap. In
approximately 20 to 60 seconds, a
sufficient quantity of water will have
drained from the steam generator so that
the drain cap can be completely removed.
3. Let the water continue to drain until the
flow completely subsides. Replace the
Steam Generator Drain Cap ቨ by
turning it clockwise until there is a
slight resistance. Close oven door.
4. Using the batch mix instructions on the
label, mix up 1 gallon of ScaleFree™
solution at a time or one gallon of
distilled white vinegar for counter top
models and 3 gallons of distilled white
vinegar for floor standing models.
Using a funnel inserted into the Steam
Relief Valve ቢ, slowly pour solution in
to the Steam Generator until full.
5. Remove funnel from Steam Relief Valve ቢ.
TURN THE SELECTION KNOB
TO THE STEAM POSITION.
THE UNIT WILL ADD WATER IF NEEDED
AND BEGIN TO PREHEAT.
