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 The supply to this machine must 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 outlet (power socket) for electrical safety.

Water supply
Connect to a suitable water supply, ensuring the pipes are flushed out to remove all foreign bodies, i.e., flux or
solder. Customers operating an oven in a hard water area must ensure that an efficient water-softening device
protects the water supply to the oven. The customers are responsible for installing and maintaining an adequate
water supply to the oven that complies with local and national water regulations.
The oven ships with a one-metre flexible hose – ¾-inch BSP connections (both ends).
Water pressure requirements: 2 to 4 bar
−Domestic pressure is usually within this parameter.
A water conditioning unit is advised.
No drain is required unless fitting a condenser unit.
Ventilation
It is the customer’s sole responsibility to arrange for adequate ventilation. It should be sufficient to ensure water
does not condense on or around the oven.
Allow a 50 mm gap at the sides and rear of this oven.
Chimneys and evacuation ducts fitted above MONO ovens should be insulated.
Before use
For hygiene reasons, MONO highly recommend thoroughly wiping the inside of the oven and all accessories with
a clean cloth soaked in warm soapy water before using the oven for the first time. Although the utmost care is
taken during assembly and pre-delivery inspection, there is always a possibility of residue contaminating the first
bake if this is not done.
Ensure that the locking casters on the base unit (if supplied) are locked into position.
Safety
Review the safety information on page 12.
Allow sufficient space for the oven door to open fully and easy loading and unloading of product trays
without people coming in contact with hot surfaces.
Racks should be available to allow cooked products to cool safely.
Oven gloves should be available at all times.
