The following procedures are to be considered by the installer; their 
personnel  must  be  qualified,  and  certified  to  perform  installation  in 
order  to comply  all  specifications  and  good  practices  to assure  the 
correct unit´s operation. 

1.- PHYSICAL INSPECTION (BEFORE ELECTRICAL CONNECTION) 

 

Check unit for possible transportation or handling damage.  

 

 

 

 

Visually check for refrigerant leaks. 

 

 

 

 

Only Open unit to install system piping. Do not remove connection´s protection until 
hydraulic circuit is to be closed. 

 

 

 

 

Check for foreign objects in fan discharge. 

 

 

 

 

Check pulley alignment, and band tension. 

 

 

 

 

Check that air intake is not obstructed and has the required space  suggested on Fig. 1    

 

 

 

 

1.- HYDRAULIC CIRCUIT INSPECTION 

Water  connections  are  NPT 

type  inner  thread  (to  identify  the  connection  diameter,  see  unit’s  data 

sheet).  The  installation  of  a  water  filter  is  necessary  on  all  hydraulic  circuits  in  order  to  avoid  solid 
particles in it, which must be installed on the return side of the circuit, and cleaned once the system´s 
initial charge is finished. 

Check water filter to be clean. 

 

Verify that all service valves are open. 

 

Check for adequate makeup water supply. 

 

Verify that all piping is water full and air has been vented out. 

 

Check Thermometers. 

 

Check Manometers. 

 

Note: 

Accessories such as Thermometers, manometers, measuring ports, etc. are recommended but not 

necessary for the unit´s operation.  

WARNING! If hydraulic circuit contains air, it may compromise the units operation. 

1.2.1.  ELECTRICAL SUPPLY INSPECTION 

The electrical piping are nipple NPT threaded conduit (1” inch diameter on all models) the units require 3 
phase grounded electrical power.  

Verify that the thermo-magnetic switch is of correct capacity for the unit.
