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

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 requir e adjus ti ng in le ve ll ing the un it.

• The unit should be positioned such that the operating panel and oven shelves are easily reachable
for loading and unloading.

THE VENT LOCATED ON THE OVEN TOP MUST NEVER BE OBSTRUCTED.

Installation Requirements

It is most important that this ov en 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 m ount one unit on top of another the 31mm ( 1¼") high spacer f eet must be
used. These short feet should be s c re wed on, an d th e unit l if ted on top of the bott om 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 appropr ia te cord and plug.

• To access the electrical connec tion terminal block, ground ing lug (marked with green), an d strain
relief, remove the back panel (4 screws).

WARNING - THIS APPLIANCE MUST BE GROUNDED

side of the unit.

• A connection elbo w and seali ng washer is supplied with this unit f or direct c onnection 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

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.

Cooking guide

Roasting

Set the oven temper ature 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 aut omatically 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 se t temperature, plac e food in the o ven, set roast cook ing 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 m ay be coo ked toget her, eg baking an d roast ing ma y be carried out at the sam e time.
Food which req uires a s lightl y higher tem per ature or m ore bro wning s hould b e pla ced at th e top of the
ove n, so that the bro il element may be s elected (with th e door shut) during the last few m inutes of `
cooking. As the top element is quite powerful, keep a close watch on browning progress.

Grilling/Broiling

Turn the oven thermostat right arou nd to GRILL/BROIL. Plac e an oven rack norm ally on the second
position fr om the top. Pl ac e the f ood on a gr il l tr a y. This al lo ws f at to drain, to prevent sm ok ing. When
the el ement has reached a bright red (5 m inutes) position the dish u nder the GRILL/BROIL elem ent.
Heat food on one side, then turn on the other side.
