NAMES AND FUNCTIONS OF THE REMOTE CONTROLLER SWITCHES
The figure below shows the remote controller with the cover opened. Note that all the items that may be dis-

●
When you operate the air conditioning system at the start of the season or after it has been stopped for a prolonged
period,
turn the power switch on (ON) 12 hours before starting the air conditioning operation
in order to protect the
air conditioning system (the current is conducted into the crank case and warms the compressor). Do not turn the power
supply switch off during the season. (The current is conducted to the crank case heater while the compressor is stopped,
keeping the compressor warm and preventing failure of the compressor due to accumulation of liquid refrigerant.)
●
Do not turn the power supply switch off during the season.
Do not turn the power supply switch of an
unused indoor unit off either, keep it “ON.”
If the power supply to one of the indoor units in the same
system is turned off, water may leak from the indoor unit (drained water overflows).
●
Turn the power supply switch off during the off-season in order to save electricity. (If the power supply switch is kept turned on, current
continues to be conducted to the crank case heater and power is consumed even if the air conditioning system is not operated.)
