cau e the refrigerant oil to deteriorate.
Do not use the following tools that have
been used with the conventional
refrigerants. prepare tools that are for
exclusive use with R410A.
(Gauge anifold, charging hose, gas leak
detector,reverse-flow check valve,
refrigerant charge base,vacuu gauge,
and refrigerant recovery equip ent.)
If refrigerant and/or refrigerant oil left on the e
tool are mixed in with R410, or if water i
mixed with R410A, it will cau e the refrigerant
to deteriorate.
Since R410A doe not contain chlorine, ga -leak
detector for conventional refrigerator will not
work.
With All-Fresh type air cinditioners, outdoor
air ay be directly blown into the roo
upon ther o off. Take this into consideration
when installing the unit.
