Notice
The total capacity of the indoor units which runs at the same time can not exceed 150% of
that of outdoor units; otherwise, the cooling (heating) effect of each unit would be reduced.
A breaker (or fuse) needs to be installed in every indoor unit, and the capacity should be in
accordance with indoor unit’s electrical parameter; all indoor units are required to be
controlled by a main switch, this switch can cut off the electric power supply in case of
emergency. The breaker (or fuse) on each indoor unit has the function of preventing a short
circuit and avoiding abnormal overload, it should be connected in a normal situation. The
main switch controls the power supply to all of the indoor unitsDŽBefore cleaning and
maintaining 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 applied 8 hours
before the operation.
It is normal for the indoor unit to still run for 20- 70 seconds after the indoor unit receives the
"stop" signal so as to make full use of any remaining heated or cooled air.
When the running modes of the indoor and outdoor units conflict, it will be indicated on the
display of the control panel for five seconds and the indoor unit will stop. At this time, change
the operation mode of the indoor unit to the one that would not conflict with the outdoor
operating mode to make the operation normal. The HEAT mode will conflict with the COOL
mode, DRY mode and FAN mode, while the COOL mode, DRY mode and FAN mode are
compatible between each other.
The appliance shall not be installed in moist places, such as the laundry, kitchen or
bathroom.
Power supply fluctuating range (+/-10%, +/-1Hz) .
Humidity range: 30%~95%.
Main switch is provided by the end user: and must comply with National, State and/or Local
Codes.
The instruction of the main power switch should be included in the user manual
The cooling range of the unit is the outdoor ambient temp 0-110 F(-17~43 ) DB, the heatingć
range of the unit (only for the heat pump type unit) is the outdoor ambient temp. 5-75 F
(-15~24) DB.
