USER NOTICES
◆When operating, the total capacity of all indoor units should be not larger than that of that
of the outdoor unit. Otherwise, it will cause insufcient cooling (heating) performance.
◆A breaker (or fuse) needs to be installed in every indoor unit, and the capacity should
comply with the indoor unit’s electrical parameter; all indoor units are required to be centralized
controlled by a main switch which can cut off the electric power supply in case of emergency. The
breaker (or fuse) on each indoor unit has the function of short circuit prevention and abnormal
overload avoiding and it should be energized in normal situation. The main switch is intended
to control the power supply of all the indoor units. Before cleaning and maintenance job being
carried out to the indoor units, it is very important to turn off the main power supply switch.
◆In order to turn on the units successfully, the main power switch should be closed 8 hours
before the operation.
◆After receiving the “turn off” signal, every indoor unit will continue to work for 20-70sec
to make use of the rest cool air or the rest heat air in the heat exchanger for preparing for the next
operation, which is certainly normal.
◆When the selected operating mode of the indoor unit conicts with the operating mode of
the outdoor unit, the malfunction indicating LED will blink 5s later on the indoor unit or remote
controller, then the indoor unit will stop. At this time, change the operation mode of the indoor
unit to the one that is compatible with the outdoor operating mode to make the operation normal.
The cooling mode can go with the dry mode, while the fan mode can go with any other mode.
◆The appliance shall not be installed in the laundry.
◆An all-pole disconnection switch having a contact separation of at least 3mm in all poles
should be connected in xed wiring
◆Main switch provided by the end user: the main switch handle should be black or gray,
and it can be locked in “OFF” position with padlock
◆The main disconnection device should be described in this manual and the height should
be recommended at 0.6-1.7m. Over current protection is required (EN 60947-3, EN 60947-2).
◆The outdoor environment temperature range for cooling is 18-43°C DB, while the outdoor
environment temperature range for heating (only for the heat pump type unit) is -16-15°C WB.
