CAUTION
•For 18K-36K models, each pipelines needs to be evacuated individually.
For 42K, only need to vacuum at the main stop valve.
•An
excess or a shortage
of
refrigerant is the main cause
of
trouble to the unit. Charge the correct refrigerant quantity
according to the description in the manual.
•Check for refrigerant leakage in detail.
If
a large refrigerant leakage occurs, it will cause difficulty with breathing or harmful
gases would occur if a
fire
was being used in the room.
•
Additional refrigerant charge
The unit has been filled with refrigerant.
Please according "Piping Requiremenr to calculate additional charge.
After vacuum pump procedure has been finished, first exhaust air from charge hose, then open valves, charge
refrigerant as "liquid • type through Liquid stop valve.
At the end, please close valves and
record
the refrigerant charging quantity.

eAvoid the wirings from touching the refrigerant pipes, plate edges and electrical parts inside the unit.
If
not do, the wires will be damaged and at the
worst,
a fire will occur.
e
1nstall an ELB (Electric Leakage Break)in the power souroe.
If ELB is not used, it will cause electric shock or fire at the worst.
•This unit uses an inverter, which means that it must be used an earth leak detector capable handing harmonics in order to prevent
malfunctioning of the earth leak detector itself.
e
Do not use intermediate connection wires, stranded wires(see <Attentions when Connect the power supply wiring>), extension
cables or control line connection, because the use of these wires may cause fever, electric shock or
fire.
eThe tightening torque of each screw shall
be
as follows.
M4: 0.74
to
0.96 ft-lb (1.0
