Installation and Operation Manual
Convection Oven ELH 5-3
Dear customer,
Please do read these operation instructions carefully, before starting to work with the convection oven.
They contain important information on correct installation and operation.
This convection oven works with hot air, which is circulating in the oven cavity, hence passing over the
food at high speed, thus guaranteeing an intensive uniform food preparation.
In appliances equipped with a humidifying system, water is injected into the oven cavity and
vaporized. This hot steam prevents food products from becoming dry and reduces the weight loss. n.

Door
For opening, just press the door handle downwards. If you do so in operation, the hot air fan
stops automatically. For closing the door, just slam it gently.
Attention: Hot air is escaping – refer to 1.
Air flap
The air flap serves for ventilation and steam exhaust from the oven cavity. In normal operation
the air flap should be closed, it is only to be opened, if excessive smoke develops inside the
oven or if the moisture content is too high.
Drip tray
The drip tray is located underneath the oven. It has to emptied and
cleaned regularly to avoid overflowing.
In case you wish to collect the dropping fat to preserve it (recommended for the
preparation of fine gravy), just put a gastronorm pan underneath the lowest grid.
7
4.5 Optional extra : Fat filter
In case your oven is equipped with a fat filter, it should always be used.
Exception: Bakery products
5. Cleaning and maintenance
Perfect and regular cleaning of your appliance is of greatest
importance. If used fat and food crusts are reheated again and again,
taste and smell of the fresh dishes will be impaired considerably.
We recommend our special cleaner (Eloma Multi-clean) for a perfect
cleaning of the appliance and its equipment.
Do not use either water jet, high pressure sprayer or steam purifier on outer surfaces.
Water jets may damage parts of the appliance or else get in
contact with electric live parts. DANGER – personal injury caused by
an electric shock. Do not spray into a hot oven cavity.
5.1 Cleaning : Cooking chamber
• Cool the oven down to about 50 - 60°C / 120 – 140° F: Leave all grids, trays,
pans etc. in the oven and spray the special cleaner onto everything including
shelf runners and interior wall.
• Leave the cleaner inside the oven for about 15 minutes to react.
Switch off and rinse the cooking chamber thoroughly with water.
Remove the drain sieve and rinse it .
Dry the inside and then leave the door open by small gap, so that the cooking
chamber is well ventilated.
Do not use sharp tools on the door gaskets.
Be careful not to damage the thermostat sensor.
5.2 Cleaning : Glass panes and outer surfaces
Glass panes
Clean only with a soft rag, do not ever use scouring agents.
Outer surfaces :
Use fat/grease dissolving cleaning agents or special stainless steel cleaners.
Do not use corrosive cleaning agents on the switch panel.
5.3 Cleaning : Grease/fat filter
Cleaning the grease/fat filter should be daily routine. If heavily contaminated
we recommend a cleaning bath or cleaning in a dishwasher. furthermore, we strongly
recommend to work with 2 filters, so that one filter can be immersed in a cleaning bath
or dishwasher while using the other one. Always rinse thoroughly with fresh water.

5.5 How to treat new sheet steel baking trays
Prior to first use, the following treatment of new sheet steel baking trays is indispensable:
1. Rinse trays with hot water
2. Dry them inside the oven at moderate temperature (approx. 130° C / 260° F) for about one
hour .
3. Use normal cooking oil and grease the trays generously on all sides and replace them into
the oven for another hour at approx. 130° C / 260° F.
The oil film dries and acts as a sort of glazing preventing any formation of rust. .
4. Do not ever use sheet steel trays when you want to use humidification i. e injection of
water.
Under no circumstances clean sheet steel trays with metal scrapers.

7. Practical use
General :
By all means pre-heat the convection oven so that the pores may close quickly after charging,
thus keeping the inside of the product juicy and tender.
7.1 Roasting
Big roasts, poultry and game
The roasting temperature should not be too high (approx. 150-180°C / 300 – 360° F).
Use grids or trays.
In addition we recommend to insert a pan, 65 mm deep underneath to collect dripping fat
which can be used as stock to prepare fine gravy.
In case of rather dry meat, brush roasts with fat.
Place roasts well apart, otherwise they will not brown at points of contact.
7.2 Roasting/frying small pieces
Steaks, cutlets, escalopes etc.
Roast on grids except forproducts made of minced meat, those should be fried on trays.
All meat and fish pieces, especially breaded/coated ones, should be brushed with melted
butter or oil, so that they can brown evenly.
For coating products use whatever bread crumbs/coating you like. Add a little mild paprika to
the mixture to make the pieces look appetisingly brown.
Small poultry can be used fresh or deep frozen. Dry poultry carefully, season, brush with fat
and place on grids.
7.3 Baking
Baked products in moulds or on trays, such as pastry, fancy biscuits,
rolls/buns and bread.
Do not forget – preheat the oven !
Set the temperature approximately 10% lower than for traditional ovens.
The lower the temperature, the more uniform is the baking result.
Use the fat filter even when baking, with the exception of big trays, big cakes and bread
loaves.
Place moulds and flan rings on grids and make sure to have sufficient clearance for hot air
circulation.
7.4 Gratinating
Hot circulating air is also used for gratinating soups, toasts, meat, fish and vegetables.
Place the products on trays so that the heat comes mainly on the surface.
11
7.5 Thawing
Deep frozen and ready cooked products in aluminium containers
Please observe the manufacturer's instructions.
The best temperature is about 140°C / 285° F, such temperatures destroy bacteria, the food
is thawed uniformly and subsequently sufficiently heated ready to be served.
7.6 Regenerating/rethermalizing
Large quantities , plates, dishes etc.
Regenerating/rethermalizing means re-heating of ready-made foodstuff.
