unit
Protection wall should be constructed with a solid material that
can block the sea breeze and the height and width of the wall
should be 1.5 times larger than the size of the outdoor unit. (You
must secure more than 700mm of space between the protection
wall and the outdoor unit for air circulation.)
• Depending on the condition of power supply, unstable power or voltage may cause malfunction of the parts or
control system. (At the ship or places using power supply from electric generator, etc).
CAUTION
f
Do not install the Air to Water Heat Pump in 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 reduce 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 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 net weight upper than 60 kg, we suggest do not install it suspended on wall, but
considering floor standing one.
CAUTION
f
If the outdoor unit is installed at a height, ensure that its base is firmly fixed in position.
f
Make sure that the water dripping from the drain hose runs away correctly and safely.
f
When you install the outdoor unit at 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 facility in building by
the law of the Ministry of Construction and Transportation.
f
While in installation or relocation of 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.
f
Do not cut or burn the refrigerant container or pipings.
f
Use clean parts such as manifold gauge, vacuum pump, and charging hose for the refrigerant.
f
Installation must be carried out by qualified personnel for handling the refrigerant. Additionally, reference the regulations and laws.
f
Be careful not to let foreign substances (lubricating oil, refrigerant other than R-32, water, etc.) enter the pipings.
f
When mechanical ventilation is required, ventilation openings shall be kept clear of obstruction.
f
For disposal of the product, follow the local laws and regulations.
f
Do not work in a confined place.
f
The work area shall be blocked.
f
The refrigerant pipings shall be installed in the position where there are no substances that may result in corrosion.
f
The following checks shall be performed for installation:
- The ventilation devices and outlets are operating normally and are not obstructed.
- Markings and signs on the equipment shall be visible and legible.
f
Upon leakage of the refrigerant, ventilate the room. When the leaked refrigerant is exposed to flame, it may cause generation of
toxic gases.
f
Make sure that the work area is safe from flammable substances.
f
To purge air in the refrigerant, be sure to use a vacuum pump.
