SERIOUS EMERGENCIES

The following are considered serious emergencies:
- Outbreak of fire in the machine room
- Explosion of pipes or pressurized parts
- Visible or noticeable leakage of coolants
- Short-circuit in the machine room
- Damage due to lightning
- Damage due to other natural events
In these cases, proceed as follows:
- Immediately disconnect the power supply using the circuit breaker on the control panel outside the room.
- In the case of small fires which allow entrance into the room, use an extinguisher.
- In the case of serious fires which make accessing the room impossible, request assistance from the local
Fire Brigade.
- When the room is secured, call technical assistance to restore the system to normal operation.
Note:If the company has its own internal specialized group able to intervene in the case of serious
emergencies, they should have the following equipment:
- protection against hot/cold burns;
- respiratory tract protection, such as masks and oxygen respirators.

19.Scheduled maintenance

ATTENTION!: Before any maintenance or cleaning operation, disconnect electrical and hydraulic power
For regular machine performance, it is recommended that every six months you:
- Check and remove any exterior dirt, damage, corrosion, or coolant leakage;
- Check for any malfunctions, or anomalous noises or vibrations;
- Check the torque on bolts;
- Check the anti-vibration supports;
- Check the intake pressure and the temperature of the incoming gas;
- Check the oil level (top off if necessary);
- Perform an oil acidity test (replace if necessary);
- Check the condition of the suction filters (replace if necessary);
- Perform the following checks for each compressor:
- temperature at end compression;
- delivery pressure;
- oil pump performance and oil differential pressure switch (if present);
- oil level;
- electrical absorption;
- resistance casing functioning (replace if necessary);
- Check the Freon level in the containers (top off if necessary);
- Check the state of the indicator light on the main line (humidity level);
- Check the state of the filters on the liquid line (replace if necessary).
- Replace the safety valve every five years, as required under EN378-4
We also recommend replacing the filters of the liquid line and for the suction line provided with the unit after
no more than 100 hours of operation.
Note:The condenser on the unit should be cleaned regularly.
For other details regarding scheduled maintenance, please consult your Maintenance contract.

20.Disposal of the system

The system must be disposed of in accordance with your country's waste management legislation and in
respect of our environment.
Before dismantling the system, it is necessary to first collect the coolant and remove the lubricant oil.
Note:These operations, as well as transport and waste processing should be performed by authorized,
specialized personnel only.
Note:The user is responsible for delivering the product for disposal to the collection centre specified by
the local authorities or manufacturer.
Violation of the norms may lead to specific sanctions, established autonomously by individual legislation by
each country belonging to the EC and which are binding to all those subject to said norms.
