Safety Cautions SiBE041525F
ix
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.
Warning
Caution
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.
