Decalcification
The COSĆ5HA has a separate boiler for each unit.
There are deliming ports and handles for each boiler
located on the base unit. The left deliming port and
handle is for the bottom unit. The right deliming port
and handle is for the top oven. To save time the boilĆ
ers should be delimed simultaneously.
The COSĆ5HA should be delimed on a monthly baĆ
sis regardless of water quality or usage. Use the
following procedure to delime the boilers.
WARNING!!
ALWAYS USE PROPER SAFETY EQUIPĆ
MENT WHEN DELIMING. Gloves and eye
safety equipment are recommended.
1. Set both mode selector switches to Steam
mode. Wait until steam is produced. This will
ensure that the water in the steam generators
is hot.
2. Turn the mode selector switches to OFF .
3. Remove both deliming port covers on the
base unit.
4. Add 10 ounces of deliming solution to the deĆ
liming bottle and then add 1 Ć3/4 gallons of

centration of phospheric acid.
5. Delime the boilers as follows:
a.) Connect the deliming hose to one of the
deliming ports on the base section.
b.) Turn the corresponding red deliming hanĆ
dle on the base unit so it is vertical. This
opens the deliming port.
c.) Pump in all of the solution.
d.) Close the deliming handle and remove
the deliming hose from the deliming port.
The handle is now horizontal.
6. Repeat STEPS 4 and 5 for the other oven.
7. Allow the ovens to sit with the deliming soluĆ
tion in them for at least 1/2 hour.
NOTE: For heavy lime build up, allow to stand
for 1 hour.
8. Drain and flush the boilers as follows:
a.) Connect a drain hose to one of the delimĆ
ing ports. Allow the boiler to drain comĆ
pletely. The drain hose is not supplied.
b.) Carefully rinse out the deliming container
and fill it with 1Ć3/4+ gallons of fresh water
only.
c.) Turn the oven to Steam and allow the boilĆ
er to fill. Wait at least 2 minutes.
d.) Connect the deliming pump to the same
deliming port on the base section.

unit so it is vertical. This opens the delimĆ
ing port.
f.) Pump in all of the water in the deliming
pump.
g.) Close the deliming handle and remove
the deliming hose from the deliming port.
The handle is horizontal.
h.) Connect the drain hose to the same deĆ
liming port on the base section.
i.) Turn the red deliming handle on the base
unit so it is vertical. This opens the delimĆ
ing port.
