•
Read the “SAFETY PRECAUTIONS” car
efully first of all and strictly follow it during the installation work in or
der
to pr
otect yourself.
•
The pr
ecautionary items mentioned below ar
e distinguished into two levels, and
.
: W
rong installation would cause serious consequences such as injuries or death.
: W
rong installation might cause serious consequences depending on cir
cumstances.
Both mentions the important items to pr
otect your health and safety so strictly follow them by any means.
•
Be sur
e to confirm no anomaly on the equipment by commissioning after completed installation and explain the
operating methods as well as the maintenance methods of this equipment to the user accor
ding to the owner’
s
manual.
•
Keep the installation manual together with owner’
s manual at a place wher
e any user can r
ead at any time.
Mor
eover if necessary
, ask to hand them to a new user
.
•
For installing qualified personnel, take pr
ecautions in r
espect to themselves by using suitable pr
otective
clothing, gr
oves, etc., and then perform the installation works.
•
Please pay attention not to fall down the tools, etc. when installing the unit at the high position.
•
If unusual noise can be hear
d during operation, consult the dealer
.
•
The meanings of “Marks” used her
e ar
e shown as follows:
•
This installation manual deals with outdoor units and general installation specifications only
. For indoor units, r
efer to pa
ge fr
om 203.
•
When install the unit, be sur
e to check whether the selection of installation place, power supply specifications, usage limita
tion (piping length, height dif
fer
ences between indoor and outdoor units, power
supply voltage and etc.) and installation spaces.
SAFETY PRECAUTIONS
Never do it under any cir
cumstances.
Always do it accor
ding to the instruction.

•
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 processing,
splice the power cord,
or share a socket with other power plugs.
This may cause fire or electric shock due to defecting contact,
defecting
insulation and over
-current etc.
•
Installation must be carried out by the qualified installer
.
If you install the system by yourself,
it may cause serious trouble such as water leaks,
electric shocks,
fire and personal injur
y,
as a result of a system malfunction.
Do not
carr
y out the installation and maintenance work except the by qualified installer
.
•
Install the system in full accordance with the installation manual.
Incorrect installation may cause bursts,
personal injur
y,
water leaks,
electric
shocks and fire.
•
Be sure to use only for household and residence.
If this appliance is installed in inferior environment such as machine shop and etc.,
it can cause malfunction.
•
When installing in small rooms,
take prevention measures not to
e
xceed the density limit of refrigerant in the event of leakage,
referred
by the formula (accordance with ISO5149).
If the density of refrigerant exceeds the limit,
please consult the dealer and install
the ventilation system,
otherwise lack of oxygen can occur
, which can cause serious
accident.
•
Use the original accessories and the specified components for
installation.
If parts other than those prescribed by us are used,
It may cause water leaks,
electric shocks,
fire and personal injur
y.
•
Install the unit in a location with good support.
Unsuitable installation locations can cause the unit to fall and cause material
damage and personal injur
y.
•
Ensure the unit is stable when installed,
so that it can withstand
earthquakes and strong winds.
Unsuitable installation locations can cause the unit to fall and cause material
damage and personal injur
y.
•
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.
•
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 circuit.
•
T
ighten the fl
are nut by tor
que wrench with specified method.
If the flare nut were tightened with excess torque,
this may cause burst and
refrigerant leakage after a long period.
•
Do not open the operation v
alves for liquid line and gas line until
completed refrigerant piping work,
air tightness test and ev
acuation.
If the compressor is operated in state of opening operation valves before
completed connection of refrigerant piping work,
air can be sucked into refrigerant
circuit,
which can cause bust or personal injur
y due to anomalously high pressure
in the refrigerant.
•
The electrical installation must be carried out by the qualified electrician
in accordance with
“the norm for electrical work”
and
“national wiring
regulation”,
and the system must be connected to the dedicated circuit.
Power supply with insufficient capacity 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 power 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 heat production or fire.
•
This appliance must be connected to main power supply by means of a
circuit breaker or switch (fuse:16A) with a contact separation of at least
3mm.
•
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 installation may result in overheating and fire.
•
Use the prescribed cables for electrical connection,
tighten the cables
securely in terminal block and relieve the cables correctly to prevent
o
verloading the terminal blocks.
Loose connections or cable mountings can cause anomalous heat production or fire.
•
Be sure to fix up the ser
vice panels.
Incorrect fixing can cause electric shocks or fire due to intrusion of dust or water
.
•
Be sure to switch off the power supply in the event of installation,
inspection or ser
vicing.
If the power 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.
•
Stop the compressor before remo
ving the pipe after shutting the
ser
vice v
alve on pump down work.
If the pipe is removed when the compressor is in operation with the ser
vice valve
open,
air would be mixed in the refrigeration circuit and it could cause explosion
and injuries due to abnormal high pressure in the cooling cycle.
•
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 water
leaks,
electric shocks,
fire.
•
Be sure to wear protective goggles and glo
ves while at work.
•
Earth leakage breaker must be installed.
If the earth leakage breaker is not installed,
it can cause electric shocks.
•
Do not bundling,
winding or processing for the power cord.
Or
, do not
deforming the power plug due to tread it.
This may cause fire or heating.
•
Do not run the unit with remo
ved panels or protections.
Touching rotating equipments,
hot surfaces or high voltage parts can cause
personal injur
y due to entrapment,
burn or electric shocks.
•
Do not perform an
y change of protective device itself or its setup
condition.
The forced operation by short-circuiting protective device of pressure switch and
temperature controller or the use of non specified component can cause fire or
burst.
