Take the following precautions to reduce the risk of property damage.
●
Do not touch the main circuit board or electronic components in the controller or remote devices.
Make sure that dust and/or steam does not accumulate on the circuit board.
●
When installing the unit in a hospital or other facility where electromagnetic waves are generated from
nearby medical and/or electronic devices, be prepared for noise and electromagnetic interference
(EMI). Do not install where the waves can directly radiate into the electrical box, controller cable,
or controller. Inverters, appliances, high-frequency medical equipment, and radio communications
equipment may cause the unit to malfunction. The operation of the unit may also adversely affect
these same devices. Install the unit at least 10 ft. (approximately 3m) away from such devices.
●
Locate the controller at a distance of at least 3 ft. (approximately 1m) between the indoor unit and
electric lighting. Otherwise, the receiver part of the unit may have difficulty receiving operation
commands.
●
If the controller is installed in a location where electromagnetic radiation is generated, make sure that
the controller is shielded and cables are sleeved inside conduit tubing.
●
If there is a source of electrical interference near the power source, install noise suppression
equipment (filter).
●
During the test run, check the unit’s operation temperature. If the unit is used in an environment
where the temperature exceeds the operation boundary, it may cause severe damage. Check the
operation temperature boundary in the manual. If there is no specified temperature, use the unit within
the operation temperature boundary of 35°F to 104°F (2°C to 40°C).
●
Read installation and appropriate user manuals for connection with a PC or peripheral devices. If a
warning window appears on the PC, the product stops, does not work properly or works intermittently,
immediately stop using the equipment.
Installation Precautions
Take the following precautions to reduce the risk of electric shock, fire or
explosion resulting in serious injury or death:
●
Perform a test run using the controller to ensure normal operation. Safety guards, shields, barriers,
covers, and protective devices must be in place while the compressor/unit is operating. During the
test run, keep fingers and clothing away from any moving parts.
After installation work for the system has been completed, explain the “Safety Precautions,” use, and
maintenance of the unit to the customer according to the information in all manuals that accompanied the
system. All manuals and warranty information must be given to the user or left near the Indoor Unit.
