START-UP 

ALL THE EQUIPMENT MUST BE COMMISSIONED BY AUTHORISED SERVICE CENTRES. 

THIS SERVICE IS LIMITED TO START-UP OF THE UNIT ONLY AND NOT THE CONNECTIONS OR INSTALLATION OF 

THE SYSTEM. 

ONLY QUALIFIED TECHNICIANS MUST PERFORM THE FOLLOWING OPERATIONS. 

 

PRELIMINARY CHECKS  

Before checking, please verify the following  
1.  the  unit  should  be  installed  properly  and  in  conformity 

with this manual. 

2.  the  electrical  power  supply  line  should  be  sectioned  at 

the beginning. 

3.  the  sectioning  device  is  locked  and  the proper warning 

“not to operate” sign is placed on the handle.  

4.  make sure no tension is present  
5.  the coils must be clean and free of obstacles  
6.  the ventilators must be free of leaves, cardboard, fixed 

obstacles (beams, barriers, etc.), snow, etc  

7.  the external ventilators must not be blocked  

 

The  external  ventilators  can  be  subject  to  a  temporary 
block,  especially  if  the  inactivity  period  before  the  first 
start-up was quite long or if outside temperature is very 
low. It is also possible to unblock them manually (ONLY 
WHEN  THE  UNIT  IS  UNPLUGGED    –  RISK  OF 
INJURES)  so  that  jams  or  electric  overloads    are 
avoided when the unit is restarted.  

REFRIGERANT SYSTEM 

Carefully check the refrigerating circuit: the presence of oil 
stains  can  mean  leakage  caused  by  transportation, 
movements or other). 
Open the cocks of the refrigerator circuit, if there are any. 
Using  the  unit  manometers,  if  present,  or  service 
manometers,  verify  that  the  refrigerating  circuit  is  in 
pressure. 
Make sure that all the service outlets are closed with proper 
caps;  if  caps  are  not  present  a  leak  of  refrigerant  can  be 
possible.

 

WATER SYSTEM 

Ensure  that  the  plumbing  system  has  been  washed.  Drain 
the wash water before connecting the unit to the system. 
Check that the water circuit has been filled and pressurised. 
Perform  a  seal  check  at  max.  working  pressure  checking 
that no leaks are present. 
Check  that  the  shut-off  valves  in  the  circuit  are  in  the 
"OPEN" position.  
Check that there is no air in the circuit. If required, bleed it 
using the vent valves in the system. 
Check  that  there  are  no  ARIES  EFFECTS  in  the  transient 
(pump and / or valve  activation/deactivation) 
When  using  antifreeze  solutions,  make  sure  the  glycol 
percentage is suitable for the type of use envisaged.

Check  that  the  circulator  pumps  are  not  blocked.  In  fact, 
their  motor  shaft  may  seize  up,  especially  after  long 
shutdowns.  Unblocking  can  be  accomplished  with  a 
screwdriver using the purge hole.  

ELECTRICAL SYSTEM 

Check  the  proper  tightening  of  the  screws  that  fix  the 
conductors  to  the  electrical  components  in  the  board 
(during  handling  and  transportation,  the  vibrations  could 
have loosened them). 
Verify that the unit is connected to the ground plant.  
Control that all panels and protection devices of the unit are 
repositioned and blocked. 
Charge the unit by closing the sectioning device, but leave 
it on OFF. 
Make  sure  that  the  tension  and  net  frequency  values  are 
within the limit of: 
230 +/- 10% single phase unit; 400/3/50 +/- 10% three-phase 
unit 
Control the unbalancing of the phases: it must be lower than 2% . 
Example:  
L1 - L2 = 388 V,    L2 - L3 = 379 V,   L3 - L1 = 377 V   
average of the measured values = (388 + 379 + 377) / 3 = 381 
maximum deviation from the average = 388-381= 7V 
Unbalancing = (7/381) x 100 = 1.83%  = ACCEPTABLE 
Operating out of the indicated limits causes the loss of the 
guarantee as well as very serious damages.  
 

IF THE CRANKCASE RESISTANCES ARE FITTED 

when the unit is started up for the first time and following all 
prolonged periods of inactivity is OBLIGATORY to connect 
the oil resistances on the compressor crankcase at least 8 
hours before the compressor is to be starter. 
BEFORE  POWERING  THE  RESISTANCES,  OPEN  THE 
COMPRESSORS COCKS, IF PRESENT. 
To  supply  the  resistances  is  necessary  to  switch  off  the 
isolator switch on the unit. 
To make sure  that hte resistances are working, check the 
power input with amperometic pliers. 
At  start-up  the  compressor  cranckase  temperature  on  the 
lower side must be higher at least of  10°C than the outside 
temperature. 
DO  NOT  START  THE  COMPRESSOR  WITH  THE 
CRANKCASE OIL BELOW OPERATING TEMPERATURE.
