tion manual
●
Installation must be carried out by the qualified installer
.
If you install the system by yourself,
it may cause serious trouble such as wa
ter leaks,
electric shocks,
fire and personal inju
ry
, as a result of a system
malfunction.
●
Install the system in full accordance with the instruction manual.
Incorrect installa
tion may cause bursts,
personal injur
y,
wa
ter leaks,
electric shocks and fire.
●
Use the original accessories and the specified components for installation.
If parts other than those prescribed by us are used,
It may cause fall of the unit,
wa
ter leaks,
electric shocks,
fire,
refriger
ant leak,
substandard
performance,
control failure and personal injur
y.
●
When installing in small rooms,
take prevention measures not to e
xceed the density limit of refrigerant in the event of leakage
accordance
with ISO5149.
Consult the expert about prevention measures.
If the density of refrigerant exceeds the limit in the event of leaka
ge,
lack of
oxygen can occur
, which
can cause serious accidents.
●
V
entilate the working area well in the event of refrigerant leakage during installation.
If the refrigerant comes into contact with naked flames,
poisonous gas is produced.
●
After completed installation,
check that no refrigerant leaks from the system.
If refrigerant leaks into the room and comes into contact with an oven or other hot surface,
poisonous gas is produced.
●
Hang up the unit at the specified points with ropes which can support the weight in lifting for portage.
And to avoid jolting ou
t of alignment,
be sure to hang up the unit at 4-point support.
An improper manner of porta
ge such as 3-point support can cause dea
th or serious personal injur
y due to falling of the unit
●
Install the unit in a location with good support.
Unsuitable installa
tion loca
tions can cause the unit to fall and cause ma
terial dama
ge and personal injur
y.
●
Ensure the unit is stable when installed,
so that it can withstand earthquakes and strong winds.
Unsuitable installa
tion loca
tions can cause the unit to fall and cause ma
terial dama
ge and personal injur
y.
●
The electrical installation must be carried out by the qualified electrician in accordance with
“the norm for electrical work”
a
nd “national
wiring regulation”,
and the system must be connected to the dedicated circuit.
P
o
wer supply with insufficient ca
pacity and incorrect function done by improper work can cause electric shocks and fire,
●
Be sure to shut off the power before starting electrical work.
Failure to shut off the po
wer can cause electric shocks,
unit failure or incorrect function of equipment.
●
Be sure to use the cables conformed to safety standard and cable ampacity for power distribution work.
Unconformable cables can cause electric leak,
anomalous hea
t production or fire.
●
Use the prescribed cables for electrical connection,
tighten the cables securely in terminal block and relieve the cables corre
ctly to prevent
o
verloading the terminal blocks.
Loose connections or cable mountings can cause anomalous hea
t production or fire.
●
Arrange the wiring in the control box so that it cannot be pushed up further into the box.
Install the ser
vice panel correctly
.
Incorrect installa
tion may result in overhea
ting and fire.
●
Do not perform brazing work in the airtight room
It can cause lack of oxygen.
●
Use the prescribed pipes,
fl
are nuts and tools for R410A.
Using existing parts (for R22 or R407C) can cause the unit failure and serious accidents due to burst of the refrigerant circui
t.
●
T
ighten the fl
are nut by using double spanners and tor
que wrench according to prescribed method.
Be sure not to
tighten the fl
are nut too much.
Loose flare connection or dama
ge on the flare part by tightening with excess torque can cause burst or refrigerant leaks which
may result in lack of oxygen.
●
Do not open the ser
vice v
alves for liquid line and gas line until completed refrigerant piping work,
air tightness test
and ev
acuation.
If the compressor is opera
ted in sta
te of opening ser
vice valves before completed connection of refrigerant piping work,
you
may incur frost bite or injur
y from an abrupt refrigerant outflo
w and air can be sucked into refrigerant circuit,
which can caus
e
burst or personal injur
y due to anomalously high pressure in the refrigerant
●
Only use prescribed optional parts.
The installation must be carried out by the qualified installer
.
If you install the system by yourself,
it can cause serious trouble such as wa
ter leaks,
electric shocks,
fire.
●
Do not perform an
y change of protective device itself or its setup condition
The forced opera
tion by short-circuiting protective device of pressure s
witch and tempera
ture controller or the use of non
specified component can cause fire or burst.
●
Be sure to switch off the power supply in the event of installation,
inspection or ser
vicing.
If the po
wer supply is not shut off,
there is a risk of electric shocks,
unit failure or personal injur
y due to the unexpected
start of fan.
●
Consult the dealer or an e
xpert regarding remo
v
al of the unit.
Incorrect installa
tion can cause wa
ter leaks,
electric shocks or fire.
●
Stop the compressor before c
losing v
alve and disconnecting refrigerant pipes in case of pump down operation.
If disconnecting refrigerant pipes in sta
te of opening ser
vice valves before compressor stopping,
you may incur frost bite or
injur
y from an abrupt refrigerant outflo
w and air can be sucked,
which can cause burst or personal injur
y due to anomalously
high pressure in the refrigerant circuit
●
Ensure that no air enters in the refrigerant circuit when the unit is installed and remo
ved.
If air enters in the refrigerant circuit,
the pressure in the refrigerant circuit becomes too high,
which can cause burst and
personal injur
y.
●
Do not run the unit with remo
ved panels or protections
T
ouching rota
ting equipments,
hot surfaces or high volta
ge parts can cause personal injur
y due to entra
pment,
burn or electric
shocks.
●
Be sure to fix up the ser
vice panels.
Incorrect fixing can cause electric shocks or fire due to intrusion of dust or wa
ter
.
●
Do not perform an
y repairs or modifications by yourself.
Consult the dealer if the unit requires repair
.
If you repair or modify the unit,
it can cause wa
ter leaks,
electric shocks or fire.
