User Notice
During using, the total capacity of indoor units in simultaneous service shall not exceed the
capacity of outdoor unit; Otherwise the cooling (or heating) output of each indoor unit will be low.
Install a circuit breaker (or fuse) to each indoor unit according to capacity of the unit and a
master circuit breaker to all indoor units. Each of the circuit breaker, which are normally on, is used
for short circuit and abnormal overload protection of indoor unit. The master circuit breaker is used
to supply or cut off power of all indoor units together. The general power supply of all indoor units
must be cut off before cleaning them.
For smooth start of air conditioner unit, the main power switch shall be put to “ON” position 8
hours before start.
Upon receiving of STOP signal by each indoor unit, the fan of related indoor unit will continue
to work for 20~70 seconds for purpose of utilizing the remaining cold air or heats in heat exchanger
and also make preparations for next use. This is normal.
When the run mode selected for indoor unit conicts against the run mode of outdoor unit,
the fault indicator on indoor unit will blink after 5 seconds or the operation of line controller display
will conict, while the indoor unit will be stopped. To resume the normal status in this case, you
shall switch the run mode of indoor unit until it does not conicts against the run mode of outdoor
unit. The cooling mode does not conict against the dehumidify mode, nor fan mode against other
modes.
During installation, do not mix communication lines with power cables. Be sure to separate
them at minimum spacing over 30cm; otherwise it might result in communication problem.
Make sure the heater band of the compressor work 8 hours continuously before the compressor
was started up when the system is being debugged or maintained.The syetem has to work more
than 30 minutes continuously once the compressor is started up,or damage to compressor may
occure.
