10•10 MARINE COMBITHERM ELECTRIC INSTALLATION AND MAINTENANCE MANUAL

PG. 26

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 switch in the OFF position.

2. Rotate the Steam Generator Drain Cap  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. As the water continues to flow from the

generator, it will have a milky or cloudy

appearance, which indicates deposits in

the generator system are beginning to

flush out. Let the water continue to

drain until the flow completely

subsides. Replace the Steam Generator

Drain Cap  by turning it clockwise

until there is a slight resistance.

4. Unscrew the cap from the

Decalcification Port . With the

use of a funnel, pour one-half gallon

(c. 2 liters) of distilled white vinegar

into the Decalcification Port.

5. Replace the cap on the Decalcification Port  and tighten securely.

Scalding water will erupt from the Decalcification

Port

 when the oven is operating unless the cap

is replaced and tightened.
