Electrical Safety Notice
Electrical safety and advice regarding supplementary
electrical protection
Commercial kitchens and food service areas are environments where electrical appliances may be located close to
liquids, operate in and around damp conditions or where restricted movement for installation and service is evident.
The appliance installation and periodic inspection should only be undertaken by a qualified, skilled, and competent
electrician and connected to the correct power supply suitable for the load as stipulated by the appliance data label.
The electrical installation and connections should meet the mandatory requirements of the local electrical wiring
regulations and any safety guidelines.
We recommend:
Supplementary electrical protection with the use of a residual current device (RCD)
Fixed wiring appliances should also incorporate a locally situated switch disconnector to connect to, which
is easily accessible for switching off and safe isolation purposes. The switch disconnector must meet the
specification requirements of IEC 60947.
Your attention is drawn to the following:
BS 7671:2018 – Guidance Note 8 – 8.13: Other locations of increased safety risk
It is recognised that there may be locations of increased risk of electrical shock other than those specifically
addressed in Part 7 of BS 7671. Examples of such locations could include laundries, where washing and drying
machines are nearby, and water is present, and commercial kitchens with stainless steel units where, once again,
water is present. Where, because of the perception of additional risks being likely, the installation designer decides
that an installation or location warrants further protective measures, the options available include:
Automatic Disconnection of Supply (ADS) using a residual current device having a residual operating
current not exceeding 30 mA;
Supplementary protective equipotential bonding; and
Reduction of maximum fault clearance time.
The provision of RCDs and supplementary bonding must be specified by the host organisation’s appointed
installation designer or electrical contractor and installed by a suitably qualified and competent electrician to comply
with Regulations 419.2 and 544.2.
WARNING Separate supplies to each deck must all be protected by a 30mA-rated
Type ‘A’ Residual Current Device (RCD).
Before installation, it is recommended that a qualified and competent
electrician first tests the electrical outlets for electrical safety.

1. Introduction
The electric modular Deck Oven is an easy-to-use practical, good-looking oven, giving an excellent heat recovery
rate and an even bake across a wide range of bread and confectionery products.
Good looking and completely reliable
Conceived with the no-nonsense requirements of both the independent and in-store baker in mind, designed to be
visually pleasing and give reliable service for many years visually. This oven will more than satisfy the most
discerning customer.
Top-quality specification
The external and internal contact surfaces are stainless steel.
Each modular deck has durable reinforced one-piece tiles and increased high-grade insulation and high-
temperature ceramic sealant to make the oven more efficient.
The oven comes with a patented integral steaming system, which reduces energy consumption and the overall size
of the oven. The system produces natural steam with the advantages of spray steam. Pre-steam is also available
to reduce the effects of long loading times.
No drainage is required.
Eco-touch ovens are supplied with TOUCH displays for user-friendly control. This display can show pictures of
product types or program numbers that have been set by the user. When not being used, the screen can show
your company logo. A voice-prompt facility is also available for basic instructions like “Bake over”.
The lights are low voltage, sealed from the chamber and easily accessed from outside the oven.
Fitted with a choice of hinged easy to clean glazed doors (using low energy-loss reflective glass for high visibility)
or metal doors, means low energy consumption and the high kW rating gives good recovery.
(0-100% heating available both top and bottom).
As it is our policy to improve our machines continuously, we reserve the right to change
specifications without prior notice.

General safety messages
CAUTION Magnets information:
−Magnetic fields in magnets, used in devices and machinery, can inhibit pulse
generators for Implantable Cardioverter Defibrillators (ICDs) and pacemakers.
Magnets can activate a switch prohibiting the ICD from delivering vital signals
such as lifesaving shocks.
−If you have an ICD or pacemaker, avoiding close or prolonged contact with
magnets or their magnetic fields is advisable. Keep magnets at least six inches
from where your device is implanted. If you feel any interference in any way,
immediately move away from the source.

5. Installation
General
A solid, smooth, level floor is recommended on which to position the oven, and access for maintenance
should be considered.
The oven is not a “built-in” design. Sufficient clearance must be left in front of the access panels (right-
hand side) for servicing.
If not chosen as an oven option, an extraction hood should be sited above the oven to disperse excess
steam and heat, which could adversely affect the bakery ceiling and ambient temperature.
A chain retainer, shorter than the power cables, should be fitted to protect them from strain if the oven
moves. Fit it to the wall or floor and the base, using the hole in the castor fixing corner plates.
Only trained engineers are authorised to install this oven. All water and electrical connections must
comply with local and national regulations.
Electrical connections
The main connection point for all deck supplies is at the top of the oven.
A wall isolator must be available to isolate the oven completely. This isolator must be easily accessible
to the oven operator.
Read the Safety section on page 12.
