Preface
Super Free Match Series Systems adopt the advanced manufacturing technology and takes the
environmental-friendly R410A as refrigerant, which is a green product in the 21st century. Please
carefully read the manual before installation and operation.
The total capacity of the indoor units which runs at the same time cannot exceed the capacity of
the outdoor units; otherwise, the cooling (heating) effect of each indoor unit would be lower
than the nominal capacity.
Make sure that the manual is kept by the operators or serviceman.
The refrigerant pipes and accessories must be designed exclusively for R410A.
It is a normal phenomenon that the fan of indoor unit will still run for 20~70 seconds after the
indoor unit receives the “stop” signal so as to make full use of the waste heat.
When the work mode of the indoors is conflict with the modes of outdoor units, it will be
indicated on the display of the wired controller in five seconds and then the indoor unit will
stop. In this case, please harmonize their work modes: the cooling mode is compatible with the
dry mode.
If the supply power fails when the unit is running, then the indoor unit will send the “start”
signal to the outdoor unit three minutes later after the power recovery.
The power cable and transmission line must not be twisted together, but instead of separated
with an interval of at least 2cm; otherwise it may be result in communication problem.
This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that they do not play with the appliance.
Cautions for the debugging and maintenance personnel:
During debugging and maintenance, before the startup of the compressor, it makes sure that the
heater belt of the compressor has been energized for at least eight hours! Once the compressor is
started, it must be guaranteed that it works continuously for at least 30 minutes, otherwise it would
be damaged!
