Precautions for adding refrigerant

• Use a scale having a precision with at least 10 g
per index line when adding the refrigerant.
Do not use a bathroom scale or similar instrument.
• Use liquid refrigerant when refilling the refrigerant.
Since the refrigerant is in liquid form, it can fill quickly.
Therefore, perform the filling operation
carefully and insert the refrigerant gradually.
CAUTION
1. Install the outdoor unit without anything blocking
the air discharging.
2. When the outdoor unit is installed in a place
exposed always exposed to strong wind like a
coast or on a high storey of a building, secure
the normal fan operation using a duct or a wind
shield.
3. In particularly windy areas, install the unit such
as to avoid admission of wind.
4. Installation in the following places may result in
trouble.
Do not install the unit in such places.
• A place full of machine oil.
• A saline-place such as the coast.
• A place full of sulfide gas.
• A place where high-frequency waves are likely
to be generated as from audio equipment,
welders, and medical equipment.
