1. Safety Summary
NOTICE
Do not touch the main circuit board or electronic components in the wired remote controller or
•
remote devices.
Make sure that dust and/or steam does not accumulate on the circuit board.
Avoid installing the unit in areas where electromagnetic waves are generated, as Electromagnetic
•
interference (EMI) may cause the equipment to malfunction. Do not install where the waves can
directly radiate into the electrical box, wired remote controller cable, or wired remote controller.
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.
If the wired remote controller is installed in a location where electromagnetic energy is generated,
•
make sure that the wired remote controller is shielded and cables are run 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 limits, it may cause severe damage. Check the
operation temperature limits in the manual. If there is no specified temperature, install the unit in a
location where the temperature limits are between 0°C to 40°C.
This manual must be read in conjunction with the installation and operation manuals of other
•
equipment being installed to get a full understanding of the equipment and installation related
topics.
Installation Precautions
WARNING
!
When using the wired remote controller with the built-in temperature sensor, do not install this
•
controller:
○
Where the controller is exposed to direct sunshine.
○
Where the unit is in close proximity to a heat source which will influence the accuracy of tempera-
ture control.
○
Where hot/cold air from the outdoors, or a draft from elsewhere (such as air vents, diffusers, or
grilles) can influence the accuracy of the detection of the actual room temperature.
Perform a test run using the controller to ensure normal operation.
•
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 end user for safe keeping and
future reference.
