From 40 m to 65 meters , the long distance kit is required.
The unit is precharged from factory with nytrogene . The installer should remove this gas and charge the units
with the charge of refrigerant R410A , shown in the following tables plus the charge by additional meter shown in
the TABLE 2
The unit is supplied with brazing connections. As an option , the unit can be supplied with gas precharge from the fac-
tory ; in that case only the TABLE 2 has to be taken into account. ( this option includes the service valves).
TABLE 2 : EXTRA REFRIGERANT CHARGE R410A BY METER OF COPPER PIPE
Legislation does not allow refrigerant gas emissions to the atmosphere, so the refrigerants have to be recy-
cled to avoid being released to the atmosphere. Those recycled refrigerants shall be processed afterwards
by an authorized waste manager.
Those components derived from the recycling of the unit have to be managed by authorized waste manager
or be left in local waste facilities according the local normative in each country.
