Safety Cautions
Store the piping to be used during
installation indoors, and keep both ends of
the piping sealed until immediately before
brazing.(keep elbows and other joints
wrapped in plastic.)
If dust, dirt, or water enters the refrigerant cycle,
it may cause the oil in the unit to deteriorate or
may cause the compressor to malfunction.
Use a small amount of ester oil,ether oil, or
alkylbenzene to coat flares and flange
connections.
A large amount of mineral oil will cause the
refrigerating machine oil to deteriorate.
Use lipuid refrigerant to charge the system.
Charge the unit with gas refrigerant will cause
the refrigerant in the cylinder to change its
composition and will lead to a drop in
performance
Before Installing the Unit
Do not install the unit in a place where there
is a possibility of flammable gas leak.
Leaked gas accumulated around the unit may
start a fire.
Do not use the unit to preserve food,
animals, plants,artifacts, or for other special
purposes.
The unit is not designed to provide adepuate
conditions to preserve the quality of these items.
Do not use the unit in an unusual
environment
The use of the unit in the presence of a large
amount of oil, steam,acid, alkaline solvents,or
special types of sprays may lead to a remarkable
drop in performance and/or malfunction and
presents a risk of electric shock, smoke, or fire.
The presence of organic solvents, corroded gas
(such as ammonia,sulfur compounds,and acid
may cause gas or water leak.)
Caution!
Do not use a charging cylinder.
The use of charging cylinder will change the
composition of the refrigerant and lead to power
loss.
Exercise special care when handling the
tools.
An introduction of foreign objects such as dust,
dirt, or water into the refrigerant cycle will cause
the refrigerating machine oil to deteriorate.
Only use R410A refrigerant.
The use of refrigerants containing chlorine(i.e.
R22) will cause the refrigerant to deteriorate.
Warning!
When installing the unit in a hospital,take
necessary measures against noise.
High-frequency medical equipment may interfere
with the normal operation of the air conditioning
unit or the air conditioning unit may interfere
with the normal operation of the medical
equipment
Do not place the unit on or over things that
may not get wet.
When humidity level exceeds 80% or when the
drainage system is clogged, indoor units may drip
water.
Installation of a centralized drainage system for
the outdoor unit may also need to be considered
to prevent water drips from the outdoor units.
