Installation Manual
4-EN
Caution
•
A double-insulated, separately-shielded, copper conductor with a minimum 600 volt rating
must be used between the 24V Thermostat Interface, the Indoor Unit and wired controllers.
•
Use copper conductors only.
• When installing the device in a hospital, communication facility, etc., provide
sufficient electrical isolation against electromagnetic interference.
Power generators, power inverters, high-frequency medical equipment, or radio communication
equipment may interfere with the normal operation of this device. Contrarily, the device may also affect
medical treatment, image broadcasting, etc., by radiating electromagnetic noise.
• Electrical wires must be run without tension.
• Do not install the device in a location where leakage of flammable gas may occur.
The leaked
gas may accumulate around the device and ignite.
• Do not install the device in environments where large amounts of oil (including
machine), sulfidizing gas, acidic chemical spray, or alkaline chemical spray is present.
These types of substances may damage internal parts and degrade performances of the device. Such
condition of the device may cause electric shock.
• Do not install the device in a high humidity environment where steam could reach the
device.
Even though this product is
designed to withstand condensation in up to 90% RH environments, long
term exposure to condensation may cause a chance for electric shock and/or device malfunction.
• Avoid direct contact to the main circuit board; also, make sure that dust does not
accumulate on the main circuit board.
• Do not install this device in a location where direct sunlight can reach or where the
temperature may become higher than 40°C (104°F) or lower than 0°C (32°F).
If the device is installed in such a location, it may result in malfunctions.
• Do not submerge this device under water.
Doing so may lead to electric shock or may cause malfunctions.
