• Read these Safety Precautions carefully to ensure correct installation.
• This manual classies the precautions into WARNING and CAUTION.
• Be sure to follow all the precautions bellow: they are all important for ensuring safety.
!
WARNING: Failure to follow any of WARNING is likely to result in grave consequences such as death or serious injury.
!
CAUTION: Failure to follow any of CAUTION may in some cases result in grave consequences.
• The following safety symbols are used throughout this manual:
Be sure to observe this instruction
Be sure to establish an earth connection
Never attempt
• After completing installation, test the unit to check for installation errors. Give the user adequate instructions concerning the
use and cleaning of the unit according to the Operation Manual.
!
WARNING
• Installation should be left to the dealer or another professional.
Improper installation may cause water leakage, electrical shock, or re.
• Install the heat pump according to the instructions given in this manual.
Incomplete installation may cause water leakage, electrical shock, or re.
• Be sure to use the supplied or specied installation parts.
Use of other parts may cause the unit to come lose, water leakage, electrical shock, or re.
• Install the heat pump on a solid base that can support the unit’s weight.
An inadequate base or incomplete installation may cause injury in the event the unit falls o the base.
• Electrical work should be carried out in accordance with the installation manual and the national electrical wiring rules or
code of practice.
Insucient capacity or incomplete electrical work may cause electrical shock or re.
• Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance.
• For wiring, use a cable long enough to cover the entire distance with no connection.
Do not use an extension cord. Do not put other loads on the power supply, use a dedicated power circuit.
(Failure to do so may cause abnormal heat, electric shock or re.)
• Use the specied types of wires for electrical connections between the indoor and outdoor units.
Firmly clamp the interconnecting wires so their receive no external stresses. Incomplete connections or clamping may cause terminal over-
heating or re.
• After connecting interconnecting and supply wiring be sure to shape the cables so that they do not put undue force on the
electrical covers or panels.
Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, or re.
• If any refrigerant has leaked out during the installation work, ventilate the room.
(The refrigerant produces a toxic gas if exposed to ames.)
• After all installation is complete, check to make sure that no refrigerant is leaking out.
(The refrigerant produces a toxic gas if exposed to ames.)
•When installing or relocating the system, be sure to keep the refrigerant circuit free from substances other than the
specied refrigerant(R410A), such as air or moisture.
(Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise or rupture, resulting in injury.)
• Be sure to establish a ground. Do not ground the unit to a utility pipe, arrester, or telephone earth.
In complete earth may cause electrical shock, or re. A high surge current from lightning or other sources may
cause damage.
!
CAUTION
• Do not install this system in a place where there is danger of exposure to inammable gas leakage.
If the gas leaks and builds up around the unit, it may catch re.
• Establish drain piping according to the instructions of this manual.
Inadequate piping may cause ooding.
•Tighten the are nut according to the specied method such as with a torque wrench.
If the are nut is tightened too hard, the are nut may crack after a long time and cause refrigerant leakage.
• Maintain proper clearances around unit per this manual.
