EMERGENCY SITUATIONS
1. The counter does not start or switches off.
Check whether there is an electrical blackout in progress;
Check that the main wall switch is on.
If the electrical interruption does not depend on the above-mentioned reasons, immediately contact
the closest service centre and fully empty the counter, placing the removed products in cold rooms or
in other equipment capable of preserving them.
2. The counter temperature is too low.
Check that the counter is not loaded beyond the recommended level and that the air vents are
not obstructed;
Start a forced defrost and clean the counter (following safety measures) to then resume standard
operation;
Make sure that the counter is not near heat sources and/or air draughts which could hinder
proper operation;
Should malfunctioning persist, immediately contact the closest service centre.
3. The counter makes too much noise.
Check that the screws and nuts are fastened all the way.
Using a level, check that the counter is level.
Should the noise persist, immediately contact the closest service centre.
4. Gas Leak or Fire.
The refrigerant circuit must not be damaged to prevent leaks into the environment. If the gas comes
into contact with the air, there is a risk of fire in the presence of a suitable trigger such as an open
flame or sparks caused by electrical equipment.
For this reason components have been adapted to prevent these risks and when they need to be re-
placed, original components which have been approved for the specific use must be requested.
If servicing due to a breakdown or malfunction, qualified personnel must always be contacted to as-
sess and perform the type of procedure required in compliance with statutory safety regulations for
this type of gas.
The equipment needed for the procedures must comply with the same requirements as the compo-
nents of the system, thus avoiding electrical equipment and flames in the presence of flammable
gases.
For specific procedures related to emptying and loading the system, proceed with equipment suitable
for
the type of gas (vacuum pump, leak detector, etc.) and in any case avoid the presence of flammables
in the premises and in particular contact with flames or sparks.
5. Other particular situations.
Metal parts must be handled with care to avoid possible and not unlikely abrasions and/or cuts as
well as possible crushing.
Removing the bottom surfaces exposes the evaporator and motor fans with the ensuing danger
that this could cause.
