Use a dedicated power circuit for the indoor unit. Do not use
a power circuit shared with the outdoor unit or any other
appliance.
●
Make sure that all wiring and protection devices are properly
selected, connected, identified and fixed to the corresponding
terminals of the unit, specially the protection (earth) and power
wiring, taking into account the applicable national and local
regulations. Establish proper earthing. Incomplete earthing
may cause electric shock.
●
Protect the indoor unit against the entry of small animals (like
rodents) which could damage the drain pipe and any internal
wire or any other electrical part, leading to electric shock or
short-circuit.
●
Keep a distance between each wiring terminal and attach
insulation tape or sleeve as shown in the figure.
