D. INSPECTING THE COOKING COMPARTMENT
At the back of the cooking compartment, a drain screen
covers the drain. Refer to Figure 3-3. The scre en
prevents large food particles from entering and blocking
the drain line. Any blockage of the drain line or screen
can reduce drainage from the cooking compartment
resulting in reduced cooking perform ance, equipment
damage, and a hazard to the operator. A blocked or slow
drain may cause:
• Hot water to collect in the compartment and spill out
when the compartment door opens.
• Pressure fluctuations in the compartm ent, resulting in
steam leaks around the door gasket, or compartment
implosion.
• Reduced convection in the compartment, red ucing cooking performance.
Before every steaming operation, inspect the c ooking compartment and remove any foo d scraps of
debris from the racks, walls, and flo or of the compartment. Pay particular attention to the drain screen.
(1) DO NOT USE the steamer if water stands in the drain opening. Arrangements must be m ade
immediately to clean the drain in accordance with t he instructions found in the Preven tative
Maintenance and Troubleshooting sec tion of this manual.
(2) Remove any food or debris that is blocking the drain or screen.
(3) Be sure the screen cove rs the drain. The screen prevents large pieces of f ood from entering and
blocking the drain.
E. PREHEATING THE STEAMER
Preheating the steamers can help insure that t he best productivity and consistent cooking is obtained. To
preheat each steamer, run a cooking cycle of approximately 15 minutes with no f ood in the cooking
compartments.
NOTE: If using a steamer with a keypad timer, set only a 1 minute cooking time for the purpose of
preheating, since the timer will only b egin to countdown once the steamer h as reached a
cooking temperature.
• BEFORE PREHEATING, inspect and clean the compartment. After preheating, th e
compartment will be too hot to inspect and clean safely.
F. DESCALING REQUIRED LIGHT FEATURE
When the programmed number of hours have elapsed, the “DESCALE
REQUIRED” light will turn on, indicating that descaling of the steam
generator must be done (See Figure 3-4). More inform ation on this
feature and the descaling procedure can be found in the Maint enance
section of this manual, Section 6, Part A (4), Monthly Maintenance.
Note: Switch does not descale unit, it is just a reminder that s teamer
must be descaled every 4-6 weeks.
CAUTION
Steam leaks around the door, cookin g compartment flooding,
reduced cooking performance, and compartment implosion
can be caused by a blocked drain or drain screen. Inspect and
clean the drain and drain screen before each use.
