Installation notes
Warning
Installation and maintenance are to be performed only by qualified personnel who are familiar with local codes and
regulations, and who are experienced with this type of equipment. Must be avoided the unit installation in places
that could be considered dangerous for all the maintenance operations.
Handling
The chiller is mounted on heavy wooden skids to protect the unit from accidental damage and to permit easy
handling and moving. It is recommended that all moving and handling be performed with the skids under the unit
when possible and that the skids not be removed until the unit is in the final location.
If the unit must be hoisted, it is necessary to lift the unit by attaching cables or chains at the lifting holes in the
evaporator tube sheets. Spreader bars must be used to protect the control cabinet and the other areas of the
chiller.
Location
A levelled and sufficiently strong floor is required.
Rubber-in-shear isolators can be furnished and field placed under each corner of the package. A rubber anti–skid
pad should be used under isolators if hold-down bolts are not used.
Vibration isolator in all water piping connected to the chiller are recommended to avoid straining the piping and
transmitting vibration and noise.
Evaporator and Condenser water flow and Delta T
Standard configuration on water side connections is 2 passes for both evaporator and condenser. Use pressure
drop curves to check if it’s the best solution.
In order to optimize performances with higher delta T ( lower water flow ), 3 passes evaporator and 3 or 4 passes
condenser configurations are available on request.
