CAUTION
Do not install the Air to Water Heat Pump in the following places.
•
The place where there is mineral oil or arsenic acid. There is a chance that parts may get damaged due to burned resin.
The capacity of the heat exchanger may be reduced or the Air to Water Heat pump may be out of order.
•
The place where corrosive gas such as sulfurous acid gas generates from the vent pipe or air outlet. The copper pipe
or connection pipe may corrode, and the refrigerant may leak.
•
The place where there is a danger of existing combustible gas, carbon fiber, or flammable dust. The place where thinner
or gasoline is handled.
This device must be installed according to the national electrical rules.
With an outdoor unit having a net weight upper than 60 kg, we suggest not installing it suspended on the wall,
but considering a floor-standing one.
•
If the outdoor unit is installed at a height, ensure that its base is firmly fixed in position.
•
Make sure that the water dripping from the drain hose runs away correctly and safely.
•
When you install the outdoor unit at the wayside, you should install it above 2 m height or make sure that the heat
from the outdoor unit shouldn't be in direct contact with passersby. (The ground for application: The revision of
regulation for the facility in the building by the law of the Ministry of Construction and Transportation.
•
While in the installation or relocating the product, do not mix the refrigerant with other gases including air or
unspecified refrigerant. Failure to do so may cause pressure increase to result in rupture or injury.
•
Do not cut or burn the refrigerant container or pipings.
•
Use clean parts such as a manifold gauge, vacuum pump, and charging hose for the refrigerant.
•
Installation must be carried out by qualified personnel handling the refrigerant. Additionally, reference the
regulations and laws.
•
Be careful not to let foreign substances (lubricating oil, refrigerant other than R-32, water, etc.) enter the pipings.
•
When mechanical ventilation is required, ventilation openings shall be kept clear of obstruction.
•
For disposal of the product, follow the local laws and regulations.
•
Do not work in a confined place.
•
The work area shall be blocked.
•
The refrigerant piping shall be installed in a position where there are no substances that may result in corrosion.
•
The following checks shall be performed regarding installation: The ventilation devices and outlets are operating
normally and are not obstructed.
•
Markings and signs on the equipment shall be visible and legible.
•
Upon leakage of the refrigerant, ventilate the room. When the leaked refrigerant is exposed to flame, it may cause
the generation of toxic gases.
•
Make sure that the work area is safe from flammable substances.
•
To purge air in the refrigerant, be sure to use a vacuum pump.
•
Note that the refrigerant has no odor.
•
The units are not explosion proof so they must be installed with no risk of explosion.
•
This product contains fluorinated gases that contribute to the global greenhouse effect. Accordingly, do not vent
gases into the atmosphere.
•
For installation with handling the refrigerant(R-32), use dedicated tools and piping materials.
•
Servicing and installation shall be performed as recommended by the manufacturer. In case other skilled persons
are joined for servicing, it shall be carried out under the supervision of the person who is competent in handling
flammable refrigerants.
•
For servicing the units containing flammable refrigerants, safety checks are required to minimize the risk of ignition.
•
Servicing shall be performed following the controlled procedure to minimize the risk of flammable refrigerants or
gases.
•
Do not install where there is a risk of combustible gas leakage.
•
Do not place heat sources.
•
Be cautious not to generate a spark as follows: Do not remove the fuses with power on.
•
Do not disconnect the power plug from the wall outlet with power on.
•
It is recommended to locate the outlet in a high position. Place the cords so that they are not tangled.
•
If the indoor unit is not R-32 compatible, an error signal appears, and the unit will not operate.
•
After installation, check for leakage. Toxic gas may be generated if it encounters an ignition source such as a fan
heater, stove, and cooker. For cylinders, make sure that only the refrigerant recovery cylinders are used.
•
Never directly touch any accidental leaking refrigerant.
•
This could result in severe wounds caused by frostbite.
