The start-up operations should be performed in compliance with all requirements of the previous  paragraphs.

All of the operations described in this chapter MUST BE PERFORMED BY TRAINED PERSONNEL ONLY. Before 
commencing service work on the unit ensure that the electric supply is disconnected. The top case and dischar-
ge line of compressor are usually at high temperature. Care must be taken when working in their surroundings.

7.2 Drive access

Access to the unit once installed, should only be possible to authorized operators and technicians. The owner of the equipment is the com-
pany legal representative, entity or person owns the property where the machine is installed.
They are fully responsible for all safety rules given in this manual and regulations. 

7.4 Periodical checks

If leak detection instruments are installed on the system, they must be inspected at least once a year, to make sure 
that they work properly.

If a defect is detected that compromises the reliable operation of the unit, the unit cannot be re-started until it has been 
repaired.

7.3 Scheduled maintenance

The owner must make sure that the unit is periodically inspected, also on-site, adequately maintained, according to the type, size, age and 
use of the system, and to the indications contained in the Manual.
Servicing during the unit’s operating lifetime and, in particular, scheduled leak detection, on-site inspections and check-ups of safety 
equipment, must be carried out as provided by local laws and regulations in force.

A

Inspection after an intervention with possible effects on the mechanical strength or after use change or in case the machine has not being working 
for more than two years. Replace all the components which are not suitable any more. Do not carry out checks at a higher pressure than the one 
indicated in the project.

leakage of refrigerant is detected, a leakage search must be carried out on the entire system.

C

Inspection after installation in a different position than the original one. Refer to point A when mechanical strength could have been affected by the 
change.

D

Leak search, following a well-founded suspicion of refrigerant leakage. It is recommended examined the system for leakage, either directly (use 
of leak detection systems) or indirectly (deduction of leakage based on analysis of operating parameters), focusing on the parts most prone to 
leakage (e.g. joints).
