Electrical Safety Notice
Electrical safety and advice regarding supplementary
electrical protection
Commercial bakeries, kitchens and food service areas are environments where electrical appliances
may be located close to liquids, or operate in and around damp conditions, or where restricted
movement for installation and service is evident.
The installation and periodic inspection of the appliance should only be undertaken by a qualified, skilled
and competent electrician, and connected to the correct supply suitable for the load as stipulated by the
appliance data label.
The electrical installation and connections should meet the necessary requirements of the local electrical
wiring regulations and any electrical safety guidelines.
We Recommend:
Supplementary electrical protection with the use of a residual current device (RCD)
Fixed wiring appliances 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:
BS 7671:2018 – Guidance Note 8 – 8.13 : Other locations of increased risk
It is recognized 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
there are washing and drying machines in close proximity, 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 includes:
Automatic Disconnection of Supply (ADS) by means of 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 so as to comply with Regulations 419.2 and 544.2.
The supply to this machine must be protected by a 30mA-rated Type ‘A’ RCD

Water Leak Safety Notice
WARNING Act immediately to get a water leak fixed by a suitably qualified
engineer and prevent death or serious injury from electrocution.
It is essential to regularly check for any signs of a water leak from an oven installation. If there is
evidence of a water leak, do not ignore it. Immediately report it to a manager or as applicable to your
organisation.
Furthermore:
Disconnect or completely isolate the oven from the electrical supply (see Chapter 6).
Place an out-of-service notice on the oven.
Contact your appointed service agent or MONO Equipment for assistance (see Back Page).
Ovens need to be maintained and serviced at appropriate intervals to help prevent water leaks from the
internal plumbing and external hose connections. See Chapter 13 for maintenance information.

Engineers Notice
If these numbers appear in the temperature window, please check the following:
888 Indicates that the control board temperature is above 80°C (176°F).
Using oven gloves, check that the cooling fan entry is not blocked.
999 Indicates there is a problem with the thermocouple.
Check for connection problems or a faulty thermocouple.

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 one or more durable reinforced tiles, 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.
Classic ovens are supplied with LED displays. All programmable parameters have separate indicators for easy
programming and extra bake time, if required. An energy saving 7-day timer is also standard.
The simplified electrical circuits aid reliability with overheat protection (on controllers and oven) to ensure long life
of controllers, all housed in splash-proof electrical enclosures. The lights are low voltage, sealed from the chamber
and easily accessed from outside the oven.
An “i” button can be used to upgrade firmware without the need of dismantling the panels.
Fitted with a choice of hinged easy to clean double-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.
