Electrical Precautions
WARNING
!
Only use electrical protection equipment and tools suited for this installation.
•
Insulate the wired remote controller against moisture and temperature extremes.
•
Use specified cables between units and the wired remote controller.
•
If the power cord is damaged, it must be replaced immediately by a suitably qualified tradesperson.
•
The polarity of the input terminals is important, so be sure to match the polarity when using
•
contacts that have polarity.
Highly dangerous electrical voltages may be used in this system. Carefully refer to the wiring diagram
•
and these instructions when wiring. Improper connections and inadequate grounding can cause serious
injury or death.
Before installing the wired remote controller or remote devices, ensure that the system has been
•
turned off, and after five minutes, power supply to the entire system has been isolated. This is to
ensure that the system has undergone and completed its proper shut-down process.
Do not open the service cover or access panel to the indoor or outdoor units without turning OFF the
•
main power supply. Before connecting or servicing the wired remote controller or cables to indoor or
outdoor units, open and tag all disconnect switches. Never assume electrical power is disconnected.
Verify with a meter and equipment.
Clamp electrical wires securely with a cable ties after all wiring has been completed. In addition, run
•
wires securely through the wiring access channel.
Secure the suspended cables at regular intervals, but not too tightly.
•
Make sure that the terminals do not come into contact with the surface of the electrical box.
•
If the terminals are too close to the surface, it may lead to failures at the terminal connection.
Avoid moisture ingress on to and in to the wired remote controller as it could cause electric shock
•
and/or damage the unit.
Do not use strong detergent such as a solvent. Clean with a soft cloth.
