Safety Cautions
Do not mix air or gas other than the specified refrigerant (R-32 /
R-410A / R-22) in the refrigerant system.
If air enters the refrigerant system, an excessively high pressure results,
causing equipment damage and injury.
If the refrigerant gas leaks, be sure to locate the leaking point and
repair it before charging the refrigerant. After charging the
refrigerant, make sure that there is no leak.
If the leaking point cannot be located and the repair work must be
stopped, be sure to pump-down, and close the service valve, to prevent
refrigerant gas from leaking into the room. Refrigerant gas itself is
harmless, but it may generate toxic gases when it contacts flames, such
as those from fan type and other heaters, stoves and ranges.
When relocating the equipment, make sure that the new installation
site has sufficient strength to withstand the weight of the
equipment.
If the installation site does not have sufficient strength or the installation
work is not conducted securely, the equipment may fall and cause injury.
Check to make sure that the power cable plug is not dirty or loose,
then insert the plug into a power outlet securely.
If the plug is dusty or has a loose connection, it may cause an electrical
shock or fire.
When replacing the coin battery in the remote controller, be sure to
dispose of the old battery to prevent children from swallowing it.
If a child swallows the coin battery, see a doctor immediately.
Installation of a leakage breaker is necessary in some cases
depending on the conditions of the installation site, to prevent
electrical shocks.
Do not install the equipment in a place where there is a possibility of
combustible gas leaks.
If combustible gas leaks and remains around the unit, it may cause a fire.
Check to see if parts and wires are mounted and connected
properly, and if connections at the soldered or crimped terminals
are secure.
Improper installation and connections may cause excessive heat
generation, fire or an electrical shock.
If the installation platform or frame has corroded, replace it.
A corroded installation platform or frame may cause the unit to fall,
resulting in injury.
Check the earth / grounding, and repair it if the equipment is not
properly earthed / grounded.
Improper earth / grounding may cause an electrical shock.
