Haier AU42NAIERA [7/26] Safety cautions
Safety Cautions
In the event of a refrigerant gas leak,
provide adequate ventilation to the room.
Do not touch the fins on the heat exchanger
with bare hands:they are sharp and
dangerous.
If leaked refrigerant gas is exposed to a heat
source, noxious gases may form.
Direct expesure to outdoor air may present a
health hazard, and it may also cause food items
to deteriorate.
Do not try to defeat the safety features of
the devices, and do not change the settings.
Defeating the safety features on the unit such as
the pressure switch and temperature switch or
using parts other than the dealer or specialist
may result in fire or explosion.
When installing the unit in a small room,
safeguard against hypoxia that results from
leaked refrigerant reaching the threshold
level.
When relocating the air conditioner,
consult the dealer or a specialist.
Consult the dealer for necessary measures to take.
Improper installation may result in water leak,
electric shock, or fire.
After completing the service work, check
for a refrigerant gas leak.
If leaked gas refrigerant is exposed to a heat
source such as fan heater,stove,and electric grill,
noxious gases may form.
Only use specified parts.
Have the unit professionally installed.
Improper installation may cause water leak,
electric shock,smoke, or fire.
Precautions for handling Units for Use with R410A
Caution!
Do not use the existing refrigerant piping
The old refrigerant and refrigerator oil in the
existing piping contain a large amount of
chlorine, which will cause the refrigerator oil in
the new unit to deteriorate.
R410A is a high-pressure refrigerant,and the use
of the existing piping may result in bursting.
Keep the inner and outer surfaces of the
pipes clean and free of contaminants such
as sulfur, oxides, dust/dirt shaving particles,
oils,and moisture.
Contaminants inside the refrigerant piping will
cause 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 manifold, charging hose, gas leak
detector,reverse-flow check valve,
refrigerant charge base,vacuum gauge,
and refrigerant recovery equipment.)
If refrigerant and/or refrigerant oil left on these
tools are mixed in with R410, or if water is
mixed with R410A, it will cause the refrigerant
to deteriorate.
Since R410A does not contain chlorine, gas-leak
detectors for conventional refrigerators will not
work.
With All-Fresh type air cinditioners, outdoor
air may be directly blown into the room
upon thermo off. Take this into consideration
when installing the unit.
Use a vacuum pump with a reverse-flow-
check valve.
If other types of valves are used, the vacuum
pump oil will flow back into the refrigerant cycle
and cause the refrigerator oil to deteriorate.
