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 256 programs can be stored and simply recalled by pressing the
appropriate number ( 1- 256 ).
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 6 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.
Stage 1 The cooking stage begins by applying a gentle fan speed of 20% for 1 minute.
Stage 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 hat can be
created and stored.
The instructions outlined in this guide are intended to ensure the safety and long life of your Merrychef oven.

1 AIR OUTLETS
These vents on the rear panels enable air which has
been used to cool internal components to escape. It
will not allow microwave energy to escape into the
environment. They must be kept free from obstruction.
OVEN CAVITY
The cavity is constructed from stainless steel and
vitreous enamelled panels.  It must be kept clean
(see CLEANING).
CONVECTION FAN, GREASE FILTER & CATALYTIC CONVERTOR
The convection fan, which is located behind the
catalytic convertor pulls air in through the filter
which removes the majority of the smoke from the
air flow. The air is then heated and returned to the
cavity through the impinger plates to produce an
even heat pattern in the oven. This layout minimises
areas where grease build up can occur. Great care
should be taken when cleaning this area of the oven
- please note the cleaning requirements on see
CLEANING.
The metal grease filter grill covering the fan must be
kept clean and free of debris (See CLEANING)
AIR INLET FILTERS ( LEFT & RIGHT )
Situated at the left and right hand side of the base
at the front. These are part of the ventilation system
and must be kept free of obstruction and cleaned on
a daily basis.

DOOR
This is a precision-made energy barrier with three microwave safety interlocks. It must be kept clean (see
CLEANING section). The door should NOT be used
to support heavy dishes.
DOOR SEALS
These ensure a tight seal around the door.  They
should be kept clean and checked regularly for signs
of damage.  At the first sign of wear they should be
replaced by a Merrychef approved Service Agent.
STEAM VENT (on rear of oven)
This enables steam to escape and prevents build up
of condensation. It will not allow microwave energy to
escape.

PROGRAMMING NUMBER PADS 1
Pre-programming allows repetitive cooking procedures to be stored for ease
of use.
Each program can comprise up to eight stages, allowing at each, independent control of Stage 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.
Programs can also be saved to a MenuKey see Page 18.
Some experimentation
will be required to
determine the correct
program for a particular
product.
