Concerning MRV Auto Restart function for H-MRV models
Haier Auto Restart function when the unit power drops down suddenly, the unit microprocessor will store the previous
working condition and when the power is on again, the unit will run as this memory.
Auto Restart function is designed basically on the MRV whole system, but it is suitable for each indoor unit individually.
If some of indoor units power cut down, but the outdoor unit and the other indoor units still work, maybe problems
will happen such as freezing at cooling mode and overload protection at heating mode on those indoor units without power.
Reason
When one or some indoor units power drops down and the other indoor units are still work, the indoor units without
the power, will keep the previous working condition before the power is off. And expansion valve keeps open at a kind of
opening rate condition as the previous requirement, so there is refrigerant flowing in the exchanger, but the indoor fan stops
working. If the units work at cooling mode, the indoor units without the power will maybe make freezing. If the unit works
at heating mode, maybe the outdoor unit compressor will stop because of the pressure or temperature protection. This is
our design basically on Auto Restart function currently.
Haier, Herewith, solemnly informs our customers, installers, distributors, etc. when making installation, please make sure
when the power is shut down whether artificially or accidentally, the whole system including outdoor unit and all the
indoor units must be off. If you do not make the installation as our indication, Haier will not be responsible for any pr oblem
resulting from this.
User Caution
About the remote cnotrol operation, above only take wired remote controller and remote controller (1) as a
example about the remote controller (2) and remote receiver use method, it is the same remote controller (1) ,
please use refer to above method.
No sleep function when use remote (2) and remote receiver.

Trouble Shooting
The following cases are not troubles.
Water flow sound is heard.
"Hua-Hua"
A sound of "Pi-Pa" is generated.
Smells are given off.
During operation, mist or steam are
blown out.
During operation, the air conditioner may
sometimes exhibit a sound of "clatter" or
"rumble". This is the common sound of
refrigerant flow but not a trouble.
This is caused by the thermal expansion
or cold shrinkage of plastics.
Sometimes there are smells in the air flow
from the indoor unit. This is caused by the
smell of cigarettes or paint coatings inside
the unit.
During COOL or DRY operation, the unit
may blow out a thin mist. This is the condensate water mist caused by sudden cooling of the indoor air blown out from the
indoor unit.
During COOL operation, it automatically
changes to FAN mode.
The system couldnt be re-started immediately
after turning off.The unit can't start?
In order to prevent frost accumulation on
the heat exchanger in the indoor unit,
sometimes it will automatically transfers
to FAN mode, but soon will return to
COOL mode.
This is due to the systems self-protection
function, which prevents it from restarting
in 3 min after stops.
Please wait
for 3 min.
18
Page 19
Trouble Shooting
During DRY operation, there is no air
sent out or fan speed cant be changed.
In HEAT mode, the outdoor unit
generates water or steam.
This occurs during removal of the frost
(in defrosting operation) on the radiator
of outdoor unit.
Defrost operation
In HEAT mode, the indoor fan still
keeps running even the unit operation
stops.
After the unit stops, the indoor fan will
continue to run for a while to eliminate
residual heat.
