● Read these Safety Precautions and perform installation work accordingly.
● The following two symbols are used to dangers that may be caused by incorrect use and their degree:
WARNING
This symbol denotes what could lead to serious injury or death if you misuse the PAR-21MAA.
CAUTION
This symbol denotes what could lead to a personal injury or damage to your property if you misuse the PAR-21MAA.
● After reading this installation manual, give it and the indoor unit installation manual to the end user.
● The end user should keep this manual and the indoor unit installation manual in a place where he or she can see it at anytime. When someone moves
or repairs the PAR-21MAA, make sure that this manual is forwarded to the end user.
Ask your dealer or technical representative to install the unit.
Any deficiency caused by your own installation may result in an electric shock
or fire.
Install in a place which is strong enough to withstand the weight of the
PAR-21MAA.
Any lack of strength may cause the PAR-21MAA to fall down, resulting in
personal injury.
Firmly connect the wiring using the specified cables. Carefully check
that the cables do not exert any force on the terminals.
Improper wiring connections may produce heat and possibly a fire.
Never modify or repair the PAR-21MAA by yourself.
Any deficiency caused by your modification or repair may result in an electric
shock or fire.
Consult with your dealer about repairs.
Do not install in any place exposed to flammable gas leakage.
Flammable gases accumulated around the body of PAR-21MAA may cause
an explosion.
Do not use in any special environment.
Using in any place exposed to oil (including machine oil), steam and sulfuric
gas may deteriorate the performance significantly or give damage to the com-
ponent parts.
When installing the remote controller in a hospital or communication
facility, take ample countermeasures against noise.
Inverters, emergency power supply generators, high-frequency medical equip-
ment, and wireless communication equipment can cause the remote control-
ler to malfunction or to fail. Radiation from the remote controller may effect
communication equipment and prevent medial operations on the human body
or interfere with image transmission and cause noise.
Wire so that it does not receive any tension.
Tension may cause wire breakage, heating or fire.
Completely seal the wire lead-in port with putty etc.
Any dew, moisture, insects entering the unit may cause an electric shock or a
malfunction.
Do not install in any place at a temperature of more than 40°C or less
than 0°C or exposed to direct sunlight.
Doing so may cause deformation or malfunction.
