INTRODUCTION
This oven offers operators the flexibility of combination cooking with additional control over
fan speed and microwave power.
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. Up to 100 programs can be stored and simply recalled by pressing a two digit
number ( 00- 99 ).
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.
Programs can have up to 4 stages each with its own time, fan speed and microwave power
settings.
A simple 2-stage program is shown:
With the oven set to pre-heat at 500°F.
St age 1 The cooking stage begins by applying a gentle fan speed of 20% for 1 minute.
St age 2 The fan speed is increased to 80% for 30seconds to brown the food.
This is only one example of an infinite number of possible multi-stage programs that can be
created and stored.
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 the start button to continue.

PROGRAMMING NUMBER P ADS 1
Pre-programming allows repetitive cooking procedures to be stored for ease of
use.
Each program can comprise up to four stages, allowing at each, independent
control of St age time, Microwave power level and Fan speed. 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
