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.
1. Install the outdoor unit without anything
blocking the discharging air.
2. When the outdoor unit is installed in a place
always exposed to strong winds like on the
coast or on a high story of a building, secure
the normal fan operation using a duct or a
wind shield.
3. Especially in windy areas, install the unit to
prevent the 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.
