Deliming Only (Models with Deliming Port
Assembly)
Boiler deliming should be performed on a weekly,
bi-weekly or monthly basis, depending on the quality
of the local water supply. See "WATER
CONDITIONING" under "GENERAL".
On steamers using a water purification system,
follow the instructions for that system to delime the
boiler. Only use the type of chemical recommended
or described in the instructions for deliming with this
type of system.
1.
Turn steamer OFF and drain boiler.
2.
Mix the deliming solution according to the
instructions for the chemical being used.
NOTE: Boiler water capacities vary between seven
to nine gallons for both gas and electric models
depending on the boiler size and BTU/KW rating.
NOTE: If deliming solution accidently comes in
contact with steamer components, lightly rinse off
with clean water.
A.
Models with Blowdown Timer - Open
the deliming assembly valve and pour the
deliming solution into the port. Close the
deliming assembly valve and proceed to
step 3.
B.
Models without Blowdown Timer - Turn
off the incoming water supply. Turn the
power switch ON to close the drain valve.
Open the deliming assembly valve and
pour the deliming solution into the port.
Close the deliming assembly valve and
proceed to step 3.
3.
Top compartments are to be in the OFF

6.
Refill boiler and allow to heat until fully
pressurized.
7.
Repeat step 6 three times.

Steamer is now ready for normal operation.
Descaler
The descaler is accessible through the hand hole
opening. It is a coiled wire wound around a solid
cylindrical core, and hangs by an open loop from the
shell's horizontal stay rod, about 4 inches from the
front of the shell. If the wire is eaten through, or if
the core of the descaler is eaten away to half its
original size, a new descaler should be installed.
To install a new descaler, stretch its wire coil so the
descaler hangs with its core completely below the
minimum water level in the boiler, but hanging free.
The descaler must not contact the bottom of the
boiler shell, electric heating elements or
regenerating steam coils.
