- Align precisely both parts of the connection (unit and tubes). There
is no error risk when both tubes have different diameters.
- Run a pressure test in the cooling tubes and a search for leaks to
verify the cooling installation.
- Create a vacuum in the installation to eliminate humidity inside the
circuit.
- Charge the unit with gas as per the data stated in the technical
characteristic table. If the equivalent length
of the cooling lines is over 6 m, an additional
charge will be needed per meter as per the
following table.
Connection of the unit to the cooling lines
For the refrigerant lines, use only cooling type seamless tubes. Under
no circumstance use sanitary type cooper pipe.
Following these steps is recommended:
- Revise and clean the tube ends to eliminate the burs from cutting
them and any other impurity that could have deposited inside or on
the outer surface. How clean the tubes are will dictate the degree or
airtightness. Also, we will avoid the dirt formation that may collapse
some spots in the cooling circuit.
- Apply isolator to the tubes, covering them and affi x it with tape. The
material used must guarantee air tightness at operating pressure
and temperature.
- Remove the plugs that protect the cooling connections of the unit
precisely at the moment of connecting the tubes.
Note: Check the undercooling of the fl uid when fi lling out the "operation
verifi cation sheets" to make sure the charge is correct.
