•
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. EMI 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 wired controller is installed in a location where electromagnetic energy is generated, make sure that the
wired 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 32°F to 104°F (0°C to 40°C).
•
Read this installation and maintenance manual for proper electrical wiring work.
Installation Precautions
•
If the remote sensors are not used with this controller, then do not install this controller...
○ In a room where there is no thermostat.
○ Where the unit is exposed to direct sunshine or direct light.
○ Where the unit is in close proximity to a heat source.
○ Where hot/cold air from the outdoors, or a draft from elsewhere (such as air vents, diffusers or grilles) can
affect air circulation.
○ In areas with poor air circulation and ventilation.
•
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.
