Adjusting the refrigerant charge
For lengths over or under 7.5 m., the nominal
charge should be increased or decreased
by the grams indicated in the corresponding
table, depending upon whether the length
of the liquid line has been increased or
decreased.
Check to see whether the refrigerant is cor-
rect by measuring overheating. In normal
summer conditions between 5 and 10° K
is correct.
Checking for leaks
Once the charging through the 1/4" nozzles
located in the circuit is complete, check for
leaks.
Application of R-410A refrigerant
Due to the characteristics of the refrigerant,

needed for efficient operation (free of humid-
ity and dirt), it is obligatory to have a special-
ized group of technicians, with a certificate
of aptitude, handle the refrigerant.

Warning
Loose cables can cause overheat-
ing of terminals or incorrect opera-
tion of the unit. Fire hazards may
also exist. Therefore, make sure all cables
are connected tightly.
Do not power or operate the unit until all
pipes and electrical connections are made.
Make sure the power supply is connected
correctly to the units, as shown in the wiring
diagrams.
