IMPORTANT SAFETY INSTRUCTIONS

When using electrical appliances basic safety precautions should be followed, including the
following:

To reduce the risk of burns, electric shock, fire, injury to persons, or exposure to excessive
microwave energy:

 Read all instructions before using the appliance.
 Read and follow the specific 'PRECAUTIONS TO AVOID POSSIBLE EXPOSURE TO

EXCESSIVE MICROWAVE ENERGY'.

 This appliance must be grounded. Connect only to a properly grounded outlet. See

'GROUNDING INSTRUCTIONS' on page 54.

 Install or locate this appliance only in accordance with the provided installation instructions.

Restrictions on use

 Use this appliance only for its intended use as described in the manual. Do not use corrosive

chemicals or vapors in this appliance. This type of oven is specifically designed to heat, cook
or toast food. It is not designed for industrial or laboratory use.

 Never use the appliance to heat alcohol, e. g. brandy, rum, etc. Food containing alcohol can

more easily catch fire if overheated. Observe caution and do not leave the appliance
unattended.

 Never attempt to deep fry in the oven.
 Some products such as whole eggs and sealed containers – for example, closed glass jars –

are able to explode and should not be heated in this oven.

 Do not operate the appliance using microwave only or combination function without food or

liquid inside the cooking chamber as this may result in overheating and may cause damage.

 The appliance should not be used to dry linen.
 Do not attempt to operate the appliance with: an object caught in the door , door that does not

close properly; a damaged door, hinge, latch, sealing surface or without food in the oven.

 Do not use the cavity for storage purposes. Do not leave paper products, cooking utensils o r

food in the cavity when not in use.

oven when not in use.

3 For your safety

eikon e2s Service and Repair Manual UL 16

Precautions when using the microwave combination oven

 When handling hot liquids, foods and containers, care should be taken to avoid scalds and

burns.

 Liquids, such as water, coffee or tea are able to be overheated beyond the boiling point

without appearing to be boiling. Visible bubbling or boiling when the container is removed
from the microwave combination oven is not always present. THIS COULD RESULT IN
VERY HOT LIQUIDS SUDDENLY BOILING OVER WHEN THE CONTAINER IS
DISTURBED OR A UTENSIL IS INSERTED INTO THE LIQUID.

 As with any cooking appliance, care should be taken to avoid co mbustion of the items within

the appliance.

Instructions for safe use of the microwave combination oven

 When heating liquids using microwave only or combination function, the c ontents should be

stirred prior to heating to help prevent eruptive boiling.

 Items should be unwrapped when using convection and combination functions.
 Excess fat should be removed during ‘roasting’ and before lifting heavy containers from the

oven.

 Food with a skin, e. g. potatoes, apples, sausages, etc. should be pierced before heating.
 In the event of glass breaking or shattering wi thin the oven, ensure that food is totally free o f

glass particles. If in doubt, dispose of any food that was in the oven at the time of the
breakage.

 Switch off the appliance at the end of all the cooking sessions for that day.

To reduce the risk of fire in the oven cavity

 Do not overcook food. Carefully attend appliance when paper, plastic, or other combustible

materials are placed inside the oven to facilitate cooking.

 Remove wire twist-ties from paper or plastic bags before placing a bag in the oven.
 Food in combustible plastic or paper containers should be transferred to a microwave/oven

proof container to avoid the possibility of ignition.

 Do not use paper products when appliance is operated in the toaster mode.
 Oversized foods or oversized metal utensils should not be inserted in a microwave/toaster

oven as they may create a fire or risk of electric shock.

 Do not cover racks or any other part of the oven with metal foil. This will cause overheating of

the oven.

 If materials inside the oven ignite, keep the oven door closed. Turn the oven off, and dis-

connect the supply cord, or shut off power at the fuse or circuit breaker panel.

Requirements to be met by operating personnel

 As with any appliance, close supervision is necessary when used by children.
 This appliance should be serviced only by qualified service personnel. Contact nearest

authorized service facility for examination, repair, or adjustment.

3 For your safety

eikon e2s Service and Repair Manual UL 17

3.4 Summar y of hazards

General rules for dealing with hazards and safety precautions

The microwave combination oven is designed to protect the user from all hazards that can reasonably
be avoided by design measures.

The actual purpose of the microwave combination oven, however, means that there are still residual
risks; you must therefore take precautions to avoid them. A safety device can provide you with a certain
degree of protection against some of these hazards. You must ensure, however, that these safety
devices are in place and in working order.

The nature of these residual risks and what effect they have are described below.

Hazard points

The following illustration shows a Merrychef e2s microwave combination oven:

Excessive microwave energy

The microwave combination oven generates microwave energy . An operation with an open or damaged
door or cavity can result in external and internal burns of body parts following exposure to microwave
energy.

Heat generation (1)

The microwave combination oven becomes hot inside the cavity and on the inside of the appliance door.
This poses a risk of burns on hot surfaces inside the microwave combination oven, and also on hot
appliance parts, food containers and other accessories used for cooking.

3 For your safety

eikon e2s Service and Repair Manual UL 28

Hot steam / vapour (2)

When cooking food the microwave combination oven may generate hot steam and vapour which
escapes when the appliance door is opened and which is removed through the air vents on the rear of
the microwave combination oven when the appliance door is closed. This poses a risk of scalding from
hot steam when the appliance door is opened. Take particular care when opening the appliance door if
the top door edge is below your field of vision.

Hot liquids

Foodstuffs are cooked in the microwave combination oven. These foodstuffs may also be liquid, or
liquefy during cooking. This poses a risk of scalding from hot liquids, which may be spilled if not handled
properly.

Live components (3)

The microwave combination oven contains live parts. This means a risk from live parts if the cover is not
in place.

Contact with cleaning chemicals

The microwave combination oven must be cleaned using special cleaning chemicals. This poses a risk
from cleaning chemicals, some of which can cause skin burns.

Parts moving against each other (4)

For various actions, such as opening/shutting the appliance door or cleaning the appliance door, there is
the risk that you will crush or cut your hand.

Undercooking of food products

Ensure all food is hot before serving to protect your guests from microbiological contamination of
foodstuffs.

3.5 Aperçu des risques

Règles générales en cas de risques et mesures de sécurité

Le four mixte est conçu tel que l'utilisateur est raisonnablement protégé de tous les risques de con­struction évitables.

Dû à l'objet du four mixte, il existe cependant des risques résiduels contre lesquels vous devez prendre
des mesures de précaution pour les éviter. Vous pouvez vous protéger jusqu'à un certain degré contre
certains de ces risques, par un dispositif de sécurité. Vous devez cependant veiller à ce que ces dis­positifs soient bien en place et qu'ils fonctionnent.

Vous apprendrez dans la suite la nature de ces risques résiduels et quels effets ils peuvent avoir.

Zones dangereuses

La figure suivante montre un four micro-ondes combiné Merrychef e2s :

Excessive microwave energy

Le four micro-ondes combiné génère de l'énergie micro-ondes. Utilisation de l'appareil avec une porte
ou une cavité ouverte ou endommagé peut causer des brûlures externes et internes des parties du
corps suite à une exposition à l'énergie des micro-ondes.

Développement de chaleur (1)

Le four micro-ondes combiné chauffe dans l'enceinte de cuisson et en face intérieure de la porte de
l'appareil. Ceci a pour conséquence un risque de brûlure sur les surfaces chaudes à l'intérieur du four
micro-ondes combiné, à l'intérieur également sur les parties chaudes de l'appareil, sur les supports
d'aliments et autres accessoires chauds utilisés pour la cuisson.

3 For your safety

eikon e2s Service and Repair Manual UL 30

Vapeur / buées chaudes (2)

Le four micro-ondes combiné génère de la vapeur et des buées chaudes qui s'échappent à l'ouverture
de la porte de l'appareil et qui, à porte d'appareil fermée, sont évacuées par les manchons d'évacuation
d'air vicié, en arrière du four. Ceci a pour conséquence des risques de brûlures par la vapeur chaude à
l'ouverture de la porte de l'appareil.
La porte de l'appareil ainsi que son verrouillage de sécurité vous protègent de la vapeur chaude si vous
utilisez la position de ventilation lors de l'ouverture de la porte et sur d'une manière générale, vous
veillez à ce que la porte de l'appareil reste intacte. Porter une attention particulière lors de l'ouverture de
la porte de l'appareil si le bord supérieur de la porte se trouve en dessous du champ du visage, comme
cela est le cas dans un kit de superposition.

Liquides très chauds

Le four micro-ondes combiné permet de cuire des aliments. Ces aliments peuvent également être
liquides ou se liquéfier pendant la cuisson. Ceci a pour conséquence un risque d'échaudure par des
liquides chauds pouvant être renversés en cas de manipulation incorrecte.

Pièces sous tension (3)

Le four micro-ondes combiné comporte des pièces sous tension. Ce qui signifie danger dû aux pièces
sous tension si le capot n'est pas à sa place.

Contact avec les nettoyants

Le four micro-ondes combiné nécessite un nettoyage à l'aide de produits nettoyant spécifiques. Ceci a
pour conséquence des risques causés par des nettoyants ayant un effet en partie corrosif.

Pièces mobiles l'une par rapport à l'autre (4)

Lors de différentes activités, par ex. ouverture/f ermeture de la porte de l'appareil ou nettoyage de la
porte de l'appareil, vous risquez de vous écraser ou de vous couper la main.

Interruption de la chaîne du froid

Assurez-vous que tous les aliments sont chauds avant de servir pour protéger vos hôtes de contami­nation microbiologique des aliments.

Select the cooling fan and check if it is operating correctly.
When increasing the fan power from L (low) to H (high) the fan

noise should become louder.

Place a microwave safe container of water into the cavity, and
close the oven door.

Select a magnetron to test the current draw at maximum output,
this will time-out after 30 seconds.

Dual magnetron model (2000W e2s variant):
Test the magnetrons individually and together.
Using heat proof gloves, r emove the container and c lose the ov en

door.
Individual magnetron test:
If there is a magnetron error present, then first reset the error.
If during the magnetro n test th e current is between 1. 1 - 2.2 A and

the error re-occurs after 8 seconds then the failure can be found
in the 230V circuit .

Refer to the schematics to find the fault for repair (fuses, SRB,
door switches, connections, power supply).

If during the magnetron test 0 A and the error reoccurs after 8
seconds then the failure can be found in the high voltage circuit.

Replace high voltage components (diode/rectifier, capacitor or
magnetron) to find out the failing component. Never measure in
the high voltage circuit. See "Replacing comp onen ts " secti on of
this manual.

Select the convection fan and check if it is operating correctly.
When increasing the fan power gradually to 100% the fan noise

should become louder.

Select the heater, it increase s t o maximum temperature and then
cycles (the convection fan is ON by default).

Check the cavity temp eratur e and h eater eleme nt curren t dra w at

9.3 Fault finding

Hardware control components

Operations communication:

1.

The oven has two main parts being the QTS assembly (keyboard, screen, logic)
and the SRB (Smart Relay Board to switch and monitor the required operation).

2.

communicates information on the operation back to the QTS.

3.

The QTS and SRB have their own Personality Module (PM) fitted with the respec­tive software to be able to communicate and work with each other.

The power provision to the QTS and the communication between QTS and SRB is
enabled via ONE cable with RJ45 connectors fitted.

Start up sequence
With the oven switch in the OFF position and the mains power ON, the QTS & SRB boards boot up.
When the oven switch is turned ON the splash screen briefly displays oven information and the cabinet

cooling fan is activated.
After completing a successful logic test, the safety relay is energised and the oven preheats or displays

a preheat temperature choice. Once preheated the oven displays the main menu if in "Full Service
Mode" or a recipe selection if in "Quick Service Mode".

Shutting down sequence
When the oven switch is turned OFF the screen displays ‘Shutting Down’ and the cooling fan operates

until the cabinet temperature has been sufficiently reduced (c avit y tem per atur e of 50°C / 122°F ).
The safety relay is de-energised and the QTS & SRB boards remain active.
