 The water pressure should not exceed the maximum  

        working pressure of 10 bar. 

NOTE         

Provide adequate safeguards in the water circuit to

 

     

make sure that the water pressure will never  

     

exceed the maximum allowable working  

                   pressure. 
 

13.  PIPING INSULATION 

 

The  complete  water  circuit,  inclusive  all  piping,  must  be 
insulated to prevent condensation and reduction of the cooling 
capacity. 
Protect  the  water  piping  against  water  freezing  during  winter 
period (e.g. by using a glycol solution or heatertape). 
 

 
 

14.  DISCHARGE FROM PRESSURE 

RELIEF DEVICES 

 
Discharge of the refrigerant into installation area has to be in 
accordance  with  local  regulations.  If  required it  is  possible to 
connect  a  1”  pipe  to  each  pressure  relef  valve  on  the 
condenser  and   

½” pipe to each pressure relief valve on the 

evaporator. 
Cross  section  and  length  of  the  discharge  line  must  comply 
with local codes. 
 
 

15.  FIELD WIRING 

 

 All field wiring and components must be installed by a  

        licensed electrician and must compy with relevant  
        European and national regulations 

        The field wiring must be carried out in accordance with 
         the wiring diagram supplied with the unit and the 

 

        

instructions given below. 

 
         Be sure to use a dedicated power circuit. Never use a  
         power supply shared by another appliance. 
 

NOTE   

Verify on the wiring diagram all electrical actions  

             mentioned below, in order to understand the operation  
             of the unit more deeply.

15.2.  Power circuit and cable 

requirements 

 
1      

The electrical power supply to the unit should be   

 

        

arranged so

 

that it can be switched on or off  

        independently

 

of the electrical supply to other  

        items of the plant and equipment in general. 
 

2      

A power circuit must be provided for connection of 

        the unit. This circuit must be protected with the  
        required

 

safety devices, i.e. a circuit breaker, a  

        slow blow fuse on each phase and an earth

 

leak  

        detector. Recommended fuses are mentioned on  
        the

 

wiring diagram supplied with the unit.

 

 
 

 Switch off the main isolator switvch before making any 

        connections (switch off the circuit breaker, remove or 
        switch off the fuses). 
 

 

15.3.  Connection of the watercooled 

water chiller power supply 

 

Using the appropriate cable, connect the power 
circuit to the L1, L2 and L3 terminals of the unit. 

2     

Connect the earth conductor (yellow/green) to the   

       earthing terminal PE.
