WEEKLY MAINTENANCE

 

 

WARNING

 

The steamer is equipped with a drain screen i

n

 the back 

of the cooking compartment. The steamer should never 
be operated without the screen in place. This screen 
prevents large food particles from entering and possibly 
blocking the drain fine. Any blockage of the drain fine 
may cause a slight buildup of back pressure in the 
compartment resulting in steam leaks around the door 
gasket. It also may adversely affect the convection 
action of the steam in the compartment, which is neces-
sary for optimum performance. 

1

.

 Make sure the drain screen and drain line are not blocked. Pour USDA 

approved drain cleaner through drain once a week. 

2

.

 Inspect for steam generator scale weekly. The frequency of steam 

generator descaling depends upon water quality and daily steam 
generator drain and washout. If steam generator scale buildup is a 
frequent problem, install a water treatment system for the steamer. See 
Water Quality Requirements on page 6. 

3. Regardless of use, steam generator should be descaled at least once a 

month.  See Steam Generator Descaling Procedure below. 

 

YEARLY MAINTENANCE

 

Clean the water line filter at least once a year as follows: 

1. Close the valve in the steamer water line

.

 Refer to figure 4-1. 

2.

 Unscrew the filter from the bottom of the strainer which is located in 

back of the steamer. Refer to figure 4-2.
