10. Cooking compartment timers are to be in the
OFF position. Turn the boiler switch ON and
open water valve if necessary.
11. Boiler is to operate under pressure for 90
minutes or per the instructions for the chemical
in use.
12. Drain boiler by normal methods. Refill boiler
and allow heat until fully pressurized.
13. Repeat step 12 three times.
14. The steamer is now ready for normal operation.
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.
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 in use then add
solution to boiler.
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. Mix the
solution in accordance with the instructions
on its container. Close the deliming
assembly valve and proceed to step 3.
B.
Models without Blowdown Timer
- Turn
off the incoming water supply. Turn the
unit ON to close the drain valve. Open the
deliming assembly valve and pour the
deliming solution into the port. Mix the
solution in accordance with the instructions
on its container. Close the deliming
assembly valve and proceed to step 3.
3. Top compartments are to be in the OFF
position. Turn the boiler switch ON and open
water valve if necessary.
4. Boiler is to operate under pressure for 90
minutes or per the instructions for the chemical
in use.
5. Drain boiler by normal methods. Refill boiler
and allow to heat up and build steam pressure.
6. Repeat step 5 three times.
7. Unit 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 that
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 the
regenerating steam coils on units so equipped.
Water Level Controls
(Low Level Cut-Off and Differential)
Solid State
1. Ensure that water is filling the boiler.
2. Check for correct voltage being applied to the
board.
3. Verify the water level control board operation
as outlined in “WATER LEVEL CONTROLS”
under “ELECTRICAL OPERATION”.
A. Does the HL LED light up and the HL relay
energize to change the contact state at
power on?
B. As the boiler fills, does the LLCO LED light
up and the LLCO relay energize to change
the contact state after the water level
reaches the LLCO probe?
