3.3 Warning signs on the combi oven
Fixed platform
A fixed platform for the combi oven is a permanently fixed worktable, a permanently fixed stand or a
permanently fixed stacking kit. These platforms are not intended to be mobile and so are not equipped
with features that would help to move them.
Positioning of warning signs
Obligatory warning signs
The following warning signs must be attached to the combi oven and optional accessories in the area
indicated so as to be easily visible at all times.
Range Warning sign Description
1High voltage / electric shock hazard warning
There is a risk of electric shock from live parts if the safety cover is
opened.
2Hot steam and vapour hazard warning
There is a risk of scalding from hot steam and vapour escaping when
the appliance door is opened.
3 For your safety
Installation manual 13

Range Warning sign Description
2Warning of hot food, hot food containers and hot liquids
There is a risk of burns from hot food and hot food containers if food
containers tip out of the shelf levels or food slips off food containers
that are not held level. This risk is particularly high for shelf levels that
lie above the sightline of the user.
Spillage of hot liquid foods can result in scalds if the upper shelf levels
are loaded with liquids or foods that produce liquid during cooking. Do
not use shelf levels that lie above your sightline for liquid foodstuffs or
food that will liquefy during cooking.
2Warning of corrosive cleaning agents injected into oven
There is a risk of chemical burns or irritation to skin, eyes and respira‐
tory system from contact with sprayed cleaning agents and their va‐
pours if the appliance door is opened during fully automatic cleaning
(ConvoClean system).

3.4 Owner obligations
Personnel for working at the combi oven
The owner must ensure that all work relating to conveying, setting up and installing the appliance, and
taking the appliance out of service, is performed solely by qualified personnel as specified in 'Require‐
ments to be met by personnel, working positions' on page 20.
Personnel for working on electrical parts
The owner/operator must ensure that only qualified electricians carry out installation, putting into serv‐
ice, servicing, maintenance or repair work on the combi oven.
Electrical installation, putting into service, servicing, maintenance, repair and testing work on the com‐
bi ovens must be carried out solely by authorized service representatives and in accordance with the
documentation specified by Convotherm for initial start-up, servicing, maintenance and repair.
The required tasks must be performed solely by qualified electricians who are suited to do so because
of their training and recent professional experience and who have the requisite knowledge of relevant
standards, rules and accident prevention regulations.
Every qualified electrician who carries out installation, initial start-up, service, maintenance or repair
work must have read and understood the installation manual.
Rules for working on electrical parts
The combi oven’s electrical connection must be made in accordance with the respective valid regula‐
tions, accepted engineering standards and the procedures listed in the installation manual.
Before putting the appliance into service and after any servicing, maintenance or repair work, electrical
safeguards and all protective equipment (mechanical and electrical) must be checked for compliance
and proper function, and, if stipulated by applicable regulations, relevant measurement-based verifica‐
tion and documentation provided.
Before any intervention work, the appliance must be disconnected from the power supply, protective
measures taken to ensure the power cannot be switched on again, and a check performed to verify
that the appliance is actually de-energized.
After de-energization has been ascertained, a waiting time of at least 15 minutes is mandatory to allow
full discharge of the DC bus capacitors.
To ensure operational and functional safety, all electrical connections must be checked and all manda‐
tory electrical tests required for putting the appliance into service and operating the appliance must be
