BMKH42M-NDG3 Owners & Installation Manual

Preface
Blueridge Free Match System adopts the cutting-edge manufacturing technology and takes global
acknowledged, environmental-friendly R410A as refrigerant, which is a green product in the 21
st
century. Please carefully read this manual before installation and operation. Instructions before reading
this manual：
(1) This unit measures on the base of UL1995.
(2) Free Match System conforms to design standard: ARI 210240-2008.
(3) For guaranteeing personal safety when operating this system, please strictly follow the
instructions listed in the manual.
(4) The total capacity of the indoor units which runs at the same time can not exceed that of the
outdoor units; otherwise, the cooling (heating) effect of each indoor unit would be poor.

(5) Switch the main power on 8 hours before starting the unit, helpful for a successful startup.
(6) It is a normal phenomenon that the indoor unit fan will still run for 20~70 seconds after the
indoor unit receives the “stop” signal so as to make full use of after-heat for the next operation.
(7) When the running modes of the indoor and outdoor units conflict, it will be indicated on the
display of the wired controller in five seconds and then the indoor unit will stop. In this case, they can
back to the normal condition by harmonizing their running modes: the cooling mode is compatible with
the dehumidifying mode and the fan mode can go with any other 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 power recovery.
(8) Cautions for the Debugging and Maintenance Personnel:
During debugging and maintenance, prior to the startup of the compress make sure the heating 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!
