6.1  PRELIMINARY INFORMATION 

 

The indicated operations should be done by qualified 
technician with specific training on the product. 

Upon request, the service centres performing the start-up; the 
electrical, water connections and the other system works are 
by the installer.  

Agree upon in advance the star-up data with the service 
centre. 

6.2  PRELIMINARY CHECKS 

 

6.3  REFRIGERANT CIRCUIT

 

6.4  HYDRAULIC CIRCUIT

 

6.5  ELECTRICAL CIRCUIT

 

Before checking, please verify the following : 

• 

the unit should be installed properly and in conformity with 
this manual. 

• 

the electrical power supply line should be sectioned at the 
beginning. 

• 

The line sectionalizing device is open, locked and 
equipped with the suitable warning 

• 

make sure no tension is present  

1.  Check carefully  the refrigerating circuit: the presence of oil 

stains can mean leakage caused by transportation, 
movements or other). 

2.  Verify that the refrigerating circuit is in pressure: Using the 

unit manometers , if present, or service manometers. 

3.  Make sure that all the service outlets are closed with 

proper caps; if caps are not present a leak of refrigerant 
can be possible.

1.  Before realizing the unit connection make sure that the 

hydraulic system has been cleaned up and the clearing 
water has been drained 

2.  Check that the water circuit has been filled and 

pressurized  

3.  Check that the shut-off valves in the circuit are in the 

"OPEN" position.  

4.  Check that there isn’t air in the circuit, if required, 

evacuate it using the air bleed valve placed in the system 
high points. 

5.  When using antifreeze solutions, make sure the glycol 

percentage is suitable for the type of use envisaged.  

Verify that the unit is connected to the ground plant  

Check the conductors tightening: the vibrations caused by 
handling and transport might cause loosing 

Feed the unit by closing  the sectioning device, but leave it on 
OFF. 

Check  the tension and line frequency values which must be 
within the limits :  

 400/3/50 

+/- 

6% 

Control the unbalancing of the phases:  

 

it must be lower than 2%

2)

3)

The working out of the limits can cause irreversible damages 
and voids the warranty. 

Check with amperometric pliers the operating of the 
compressor carter heating. Before proceeding with the start-
up, leave the unit powered with stopped compressors for 
some hours.
