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
c
arbonate, 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
key in the OFF position.
2. Open oven door. 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.
