Carrier 42BB Manual De Instalación, Operación Y Mantenimiento página 61

* For the assembly of the hydraulic network it
is advisable to use a water filter, type "Y", at
the conditioner inlet or a temporary filter in
order to avoid the entrance of dirt that may
obstruct the coil.
* In order to prevent the destruction of the
coils, which are manufactured in copper, it is
necessary to adjust the thread with two pipe
wrenches. One of them performs the
adjustment and the other holds the copper
connection, leaning in the direction opposite
to the effort made to adjust the thread. See
drawing.
