RISK OF OVERTURNING 

 

The manufacturer disclaims all responsibility for damage 
to  objects  and/or  persons  resulting  from  the  equipment 
being  wrongly  removed  from  the  pallet,  or  from  the 
operation  being  made  by  unsuitable  personnel,  with 
improper means/protections and without complying with 
the  existing  laws  on  manual  handling  of  loads  and  with 
the operations described in this manual.

REFRIGERANT SCALE SCREW RELEASE

 
The unit is transported, with the scale blocked by a locking screw to 
avoid damaging the load cell. The scale locking screw is placed on 
the  equipment  bottom  side  (see  the  box  shown  above)  and  is 
formed by a bolt. For commissioning, unscrew the screw.
 
 
 
 

Commissioning 

 

7.1 

Connections 

 
The unit has to be positioned on a horizontal surface to ensure the 
correct operation. 
The  unit  has  to  be  connected  to  the  electric  mains  following 
instructions on the identification plate of the unit applied next to the 
main switch, mainly as to applicable voltage and power.
 

 

The A/C service stations are designed for 230VAC, 50Hz. 

Follow the information on the rating plate.

 

7.1.1 

Positioning and connection

 

 

HANDLING: During handling, the minimum devices required 
for  correct  handling  shall  be  ensured,  as  provided  for  by 
accident prevention provisions. 

 

POSITIONING: Place the unit in a stable place. The location 
must  be  well  ventilated,  with  a  good  rate  of  change  of  air. 
The  unit  must  be  located  at  least  10  cm  from  any  potential 
obstacles to its internal ventilation.
rain and excessive humidity as they can irreparably damage 
it. In addition, the equipment must never be directly exposed 
to the sunrays or to excessive dust. 

 

INSTALLATION: the unit must be installed by a 
technician  in  scrupulous  observance  of  in  accordance  with 
electrical engineering principles. The use of the equipment in 
explosive atmosphere is forbidden.

 

CONNECTIONS:  since  the  unit  is  connected  to  the  main 
power  supply,  it  must  be  properly  grounded  with  its  pow
plug GND pin. Failure to ground the unit can damage it and 
constitutes a risk of fatal injury to the operator. Position the 
unit  so  that  the  power  plug  is  easy  for  the  operator  to 
access.
