OPTIONS

The refill type can be chosen from two
options:

STANDARD

and

BUS

(to be used for

high capacity - > 3 Kg - A/C systems only.

The misuse of the charging mode setting

may lead to charging inaccuracies.

Excludes

includes

the oil charging

cycle from the automatic procedure
(ON/OFF choice). The setting allows the
user to exclude the oil charging even if an
automatic oil charging mode with scale has
been chosen

When requested you may release

NCG’s by

following the directions on Pg.7 Air pressure
relief.
