6. Maintenance

6.1

General

This section contains both preventive and corrective mainte-
nance information. Preventive maintenance may be per-
formed by maintenance personnel at the establishment in
which the cooker is installed. It is recommended that user
personnel never attempt to make repairs or replacements to
the equipment. Assistance in service methods or a current
directory of authorized agencies may be obtained from Mar-
ket Forge Industries.

6.2

Daily Cleaning

After each period of daily operation (more frequently as re-
quired to maintain cleanliness), the cooker should be thor-
oughly cleaned by completing the following steps:

1. Place a 4" deep steam pan under the steamer, and turn

drain valve to “

OPEN

.” Allow all water to drain before

emptying the pan.

2. Allow the steamer to cool before removing rear strainer,

left and right racks, and ala-carte shelf..

3. Wash cooking compartment and steam generator interi-

ors using a mild detergent. Rinse and dry thoroughly.

4. Remove drip/spill trough.

5. Wash all removed pieces with a mild detergent and non-

abrasive pad. Rinse and dry thoroughly.

6. Replace all removed parts.

7. Leave the door slightly ajar to prolong life of the door

gasket.

6.3

Preventive Maintenance

A good preventive maintenance program begins with the
daily cleaning procedure described above. Additional pre-
ventive maintenance operations are presented in this section.
In establishments that employ full-time maintenance person-
nel, the tasks described can be assigned to them. For other
installations, tasks requiring mechanical or electrical experi-
ence must be performed by an authorized service agency.

CAUTION: Under no circumstances should hardware (or
parts) be replaced with a different size or type other than as
specified in the parts list. The hardware used in the cooker
has been selected or designed specifically for its application,
and the use of other hardware may damage the equipment,
can present a safety hazard, and will void any warranty.

The following sections set forth minimum preventive mainte-
nance procedures that must be completed periodically to as-
sure continued trouble-free operation.

6.4

Periodic Cleaning

If you should experience build up of lime or mineral deposits
in the steam generator, it may be cleaned easily using vin-
egar & water. if dealing with severe scaling use Market
Forge's descaling product, “Total Concept™” with water.

1. With drain closed, fill generator with 2 gallons water

and 1/2 gallon vinegar. Close door.

2. Turn power switch to “

ON

”.

3. Place timer into “

HOLD

” mode. Let run for one hour.

4. Open door. Turn the drain valve to “

OPEN

”. Allow Vin-

egar/Water solution to  drain into the pan. Empty as
needed.

5. Refill steamer with water, and drain again flushing out

any remaining vinegar/water solution. Empty as needed.

6. Replace any removed parts, close valve, and refill

steamer. Steamer is now ready for use.

7. If “Total Concept™” is needed repeat above procedure,

replacing vinegar with “Total Concept™”.
