We are confident that you will be delighted with your TURBOFAN OVEN, and it will become a most valued
appliance in your commercial kitchen.
A new oven can seem very complex and confusing at first glance. To ensure you receive the utmost
benefit from your new Turbofan, there are two important things you can do.
Firstly
Please read the instruction book carefully and follow the directions given. The time taken will be well
spent.
Secondly
If you are unsure of any aspect of the installation, instructions or performance of your oven, contact your
E311 dealer promptly. In many cases a phone call could answer your question.
Model Options
This manual covers models E311 and E311MS.
The E311 models feature a vitreous enamel front exterior finish and full glass door.
The E311MS models feature a stainless steel front exterior finish and a stainless steel exterior door with
full viewing window.
The functionality of both model series are identical.
Note: Both model series are marked with the control panel coding “31”, however the full and specific
model option is found on the appliance rating plate.
Introduction
2

Before Connection to Power Supply
• Remove all packing.
• Check equipment and parts for damage. Report any damage immediately to the carrier and
distributor.
• Remove protective plastic coating from the side panels.
• Check that the following parts have been supplied with your oven:
4 x 4” Legs (Canada only)
4 x Oven racks
• Report any deficiencies to the distributor who supplied the oven.
• Fit the feet to the oven.
• Fit door handle to oven door.
• Check that the available power supply is correct to that shown on the rating plate located on the
right -hand side panel.
208V AC 60Hz, 14.0A, 2.9kW @ 208V 208-220V AC 50Hz, 14.6A, 3.2kW @ 220V
220-240V AC 60Hz, 13.0A, 3.1kW @ 240V 230-240V AC 50Hz, 13.0A, 3.1kW @ 240V
Location
• To ensure correct ventilation for the motor and controls the following minimum installation
clearances are to be adhered to:
• Position the oven in its working position.
• Use a spirit level to ensure oven is level from side to side and front to back. (If this is not carried
out, uneven cooking could occur). The feet/legs used with bench/floor mounting or provided with
stands are adjustable and will require adjusting in levelling the unit.
• The unit should be positioned such that the operating panel and oven shelves are easily reachable
for loading and unloading.
3
Installation
Important:
THE VENT LOCATED ON THE OVEN TOP MUST NEVER BE OBSTRUCTED.
Installation Requirements
It is most important that this oven is installed correctly and that operation is correct
before use.
Installation shall comply with local electrical, health and safety requirements.
Double Units
• When it is desired to mount one unit on top of another the 31mm (1¼") high spacer feet must be
used. These short feet should be screwed on, and the unit lifted on top of the bottom unit, where it
locates safely under its own weight, for normal applications.
Top 8” / 200mm
Rear 1” / 25mm
Left-hand side 1” / 25mm
Right-hand side 1” / 25mm

Electrical Connection
• Ensure unit is fitted with appropriate cord and plug.
• To access the electrical connection terminal block, grounding lug (marked with green), and strain
relief, remove the back panel (4 screws).
WARNING - THIS APPLIANCE MUST BE GROUNDED
Water Connection (Canada only)
• A cold water supply should be fitted to the water inlet which is located on the rear of the left hand
side of the unit.
• A connection elbow and sealing washer is supplied with this unit for direct connection of a 1/2” ID
hose, and is recommended for easy installation and service.
• Connect water supply - Max inlet pressure 80psi / 550kPa.
• Turn on water supply to check for leaks.
Before Use
• Operate the oven for about 1 hour at 200°C (400°F) to remove any fumes or odours which may be
present.

It is recommended that the GRILL/BROIL mode is only used with the oven door open as the
oven fan is then automatically off. If however the GRILL/BROIL mode is used with the door
closed, the elements will cycle on/off when oven temperature rises above 300°C (570°F) to
prevent damage to the oven.
2. Load oven
Place an oven rack normally on the top position. When the element has reached bright red
(5 minutes), position the dish under the GRILL/BROIL element. Heat food on one side, then

Cooking guide
11
This TURBOFAN oven will cook a greater quantity of food faster, at a lower temperature and more evenly
than an ordinary oven. As many excellent recipe books are published, it is not our intention to list recipes,
but to provide a temperature and time chart as a guide.
When the door is opened the fan will switch off but elements will remain on to provide quick heat recovery.
A high powered top element is fitted for toasting or broiling.
Baking
Select a temperature up to 20°C (35°F) lower than used in a conventional oven and preheat until
HEATING indicator goes out. When the HEATING indicator goes out, the oven has reached the
desired temperature and food may be placed in the oven allowing air space between cooking
utensils and around the oven walls.
The following are only approximate guides - use your judgement.

Cooking guide
Roasting
Set the oven temperature to 150-170°C (300°F-340°F). The hot air circulating in the oven reduces
moisture loss and shrinkage. Roasting times are reduced by approximately 10 minutes per kg.
Roast-’n’-Hold
This system will automatically cook food for a set time, then hold the oven at a preset temperature
indefinitely to maintain food at a serving temperature after cooking has been completed.
When the oven has reached the set temperature, place food in the oven, set roast cooking time and
depress the Roast ’n’ Hold button. The hold indicator will come on when cooking is complete.
To return to normal operation, push the Roast ‘n’ Hold switch again (switch will cease illuminating).
Browning
Different foods may be cooked together, eg baking and roasting may be carried out at the same time.
Food which requires a slightly higher temperature or more browning should be placed at the top of the
oven, so that the broil element may be selected (with the door shut) during the last few minutes of `
cooking. As the top element is quite powerful, keep a close watch on browning progress.
Grilling/Broiling
Turn the oven thermostat right around to GRILL/BROIL. Place an oven rack normally on the second
position from the top. Place the food on a grill tray. This allows fat to drain, to prevent smoking. When
the element has reached a bright red (5 minutes) position the dish under the GRILL/BROIL element.
Heat food on one side, then turn on the other side.
Toast, sandwiches etc., on a scone tray on the top rack position.
