SAFETY PRECAUTIONS
DANGER
High voltage
Circuit breaker
Modem (optional)
Always turn off the main power supply in the facility (※1)
before inspecting the interior of the control box.
※
This is important because high voltage remains at the
circuit breaker and the optionally provided modem even
though the circuit breaker in the control box is turned off.
Always observe the following points before operating or
inspecting a unit.
※1: with 30 Amps circuit breaker
Always turn off the main power supply in the facility (※1)
before disconnecting the power plug.
https://daikin-p.ru
Do not touch the condenser fan while power to the
unit is ON.
Before removing the condenser fan cover, turn off the
circuit breaker and disconnect the power plug.
During air-cooled operation : Condenser fan may start
and stop automatically for
the refrigerant high
pressure control.
During water-cooled operation: Condenser fan may start
and stop automatically for
cooling of the control box.
