Installation Procedures
Selection of the installation place
Avoid install the air
conditioner near the place
where possibility of
inflammable gas leakage
exists.
Select the place so as to not
annoy neighbor with the
hot/cold air or noise.
Refrigerant piping connection
During installation,if refrigerant leakage occurs,take
ventilation measurement immediately.
As soon as the leaked refrigerant gas meets fire,
poisonous gas will generate.
During the operation, if refrigerant gas leakage exists, execute venting practice at once. Once refrigerant gas contacts
fire, harmful gas will produce.
Make sure no refrigerant gas leakage after installation. If refrigerant gas contacts fire from warmers or furnaces, harmful
gas will produce.
Connecting method
Make the pipe as short as possible to ensure high efficiency.
Apply refrigerant oil at half union and flare nut.
Bend piping with as wide angle as possible to avoid pipe crash.
When connecting pipe, hold the pipe center-to-center and screw nut on by hand, then tighten with two spanners.
Refer the tighten moment in following table. As shown in Fig.
Be careful not to let foreign matters, such as sands enter the pipe.
If tighten nut without pointing to center
it could cause screw thread damage
which could lead to gas leakage.
Installation place
If some obstacles exit, it
may cause capacity
reduction or noise
increase.
Snow protection work is necessary where outdoor unit is blocked up by snow.
It is advisable not to install the air conditioner at the following special place. It
may cause malfunction; consult the sales dealer when you have to install the unit
on such a place.
The place where corrosive gas generates (Hot spring area etc.)
The place where salt breeze blows (seaside etc.)
The place dense soot smoke exists.
The place where humidity is extraordinarily high.
The place where near the machine which radiates the electromagnetic wave.
The place where voltage variation is considerably large.
WARNING
Install the air conditioner firmly on the foundation
that can fully support the weight of the unit.
After finishing installation,confirm the refrigerant gas
does not leak.
If the refrigerant gas leaks in the room,once it meets
heater,burner and gas stove etc.fire source,the poisonous
