INTRODUCTION
This Mealstream oven offers operators the flexibility of three heating functions; microwave
only, convection only, and combination cooking.
Combination cooking enables high quality results to be achieved in a fraction of the time
taken by conventional cooking, particularly when baking, browning, roasting, grilling or
producing gratinee dishes.
Once established, precise instructions for combination or convection cooking of selected
items may be programmed into the ovens memory so that they can be repeated easily
and accurately.
Multi-Stage Programming
The oven controls offer even greater flexibility by allowing multi-stage programming. This
enables the exact conditions required for quality results to be set according to the food type.
A typical 3-stage program is shown:
The Oven is pre-heated at 400°F.
Stage 1 begins by applying a gentle microwave power of 25% (ideal for defrosting) while the
convection is set to 400°F.
In Stage 2 the microwave power increases to maximum (100%).
In Stage 3 the final browning stage, the convection temperature remains at 400°F with no
microwave energy applied.
This is only one example of an infinite number of possible multi-stage programs that can be
Note:
Remember convection temperature takes time to change. Do not
expect an instant response when a different temperature is activated.
The instructions outlined in this guide are intended to
ensure the safety and long life of your Merrychef oven.

Hints and Tips for improved operation
• Care should be taken when defrosting in a hot oven.
For best results, defrost first thing in the morning when the oven
is still cold.
• Combination and convection only cooking may be carried out on
a rising temperature but extra attention must be given to timings.
• Convection only cooking can be carried out without setting a time.
• Microwave heating may be introduced part-way through a
manually set convection only cycle.
However, we strongly recommend that only the most experienced
microwave operator uses this facility as the microwave energy
will then be on a time set for convection cooking.
Cooking may be interrupted by opening the door. Close the door and
touch a power button to continue.
13
PROGRAMMING NUMBER PADS ( 01-99 )
Pre-programming allows repetitive cooking procedures to be stored for ease
of use.
Each program can comprise up to three stages, allowing at each, independent
control of Convection temperature, Stage time and Microwave power level.
However, programs must be used with caution, since if the food to cook varies
in weight or density, adequately cooked food may not be achieved. Therefore,
it is vital that all food prepared for service should be checked to ensure that
core temperatures have been achieved.
Some experimentation
will be required to
determine the correct
program for a particular
product.
