5.8 Long piping length and high drop
The max. high drop can be up to 50m when outdoor is lower than indoor. And the max. single way
total pipe length can be up to 300m.
5.9 Easier maintenance
a. Auto diagnose function
The PCB will check the unit automatically, if there is error such as compressor wiring, sensor,
communication etc., the PCB will indicate failure code via the LED or the wired controller. Many
test modes or backup running modes are possible for easier test running and troubleshooting.
b. Auto restart function
The unit has memory function, when the power is cut off, the unit will memorize the operation state
at the moment, when the power comes again, the unit will run as the previous state.
5.10 Reliable performance
a. High COP
High efficiency and great energy saving are the purchased aim for every air conditioning
manufacturer. Haier MRVII has been designed to get high COP from the reasonable structure and
the excellent electric system.
b. Approved for RoHS certificate
All the parts in the unit have been approved for RoHS certificate. The parts are in conformance
with RoHS directive. Thus Haier MRVII will be environmental for human and nature.
The directive is to approximate the laws of the Member States on the restrictions of the use of
hazardous substances in electrical and electronics equipment and to contribute to the protection of
human health and the environmentally sound recovery and disposal of waste electrical and
electronic equipment.
