they could cause irritation to the skin or eyes. The manufacturer’s instructions must betaken as
strictly observed.
When applying detergents and degreasing products, rubber gloves, face mask and protective goggles must be worn, in
accordance with the applicable safety regulations.
If the oven is cleaned everyday, the operation can be completed quickly, giving an appliance in perfect condition and
ready for use the next day.

The appliance is made of high quality stainless steel. However, under certain conditions, corrosion may appear.
To keep the stainless steel surfaces permanently free of corrosion, only use suitable cleaning products.
To ensure the correct operation of the equipment, Fagor Industrial recommends the following maintenance tasks are
performed daily:
•The machine should be cleaned at the end of each working day.
•ATTENTION: Do not use jets of water, pressure or steam cleaners to clean the machine or its environment.
•DO NOT use abrasive or corrosive, materials, solvents, chlorine or chlorine-based products or hypochlorites to
clean the machine. Only use products suitable for cleaning industrial dishwashers in the correct doses.
After switching off and draining the machine every day:
•Disconnect the power switch.
•Remove the frames and clean with a brush under a strong jet of water.
•Replace all the parts correctly.
•Thoroughly clean the chamber; attached food waste should be removed with a brush.
•At the end of the day, the door of the machine should be left open.
Before carrying out any cleaning operations, the appliance must be disconnected at the mains.
Some models are equipped with a drainage pipe for cleaning, as well as for collecting the possible flow of liquids
from the food. It is essential to remove and clean the drain lid during the cleaning operation , to prevent it from being
blocked up with solid waste. This is so that any liquids present do not become stagnant. It should be installed again
after cleaning.
The appliance must be switched off if cleaning with water. Panels should not be moved to access electrical
components except by technical staff authorised to carry out maintenance and repair operations.
The inside of the cooler should be cleaned with great car.
7.2. REGULAR CHECKS PERFORMED BY THE USER

7.4. SPECIALISED MAINTENANCE
To ensure that the equipment is in perfect and safe condition, it should be maintained and serviced by an Authorised
Service Centre at least once a year.
DANGER
• High voltage.
• Before removing the panel from the machine, accessing components and carrying out work on live
components, disconnect the machine from the power supply.
Use the resources and tools suited to each operation on the machine.

•Checking the correct operation of the dispensers.
•Tightening of the electrical connections on the terminals, once a year.
Check that the temperature of the premises does not exceed that indicated for your machine.
The guarantee will be made void if there is insufficient ventilation.
Check that the doors close properly.
Do not disassemble the mobile components guards or front panels without first having turned the appliance
off.
Gloves must be worn before accessing the appliance area, given the existence of high temperatures of some
components, with the resulting risk of burns.
If the supply hose is damaged, it should be replaced by authorised technical personnel in order to avoid
risks.
It if is replaced, the earth pin must be positioned again.
If a cable requires replacement, the cross-section must never be reduced.
If it is necessary to disassemble the inner lid of the electrical installation, it is extremely important to leave it
exactly as it was when reassembling it.
