Auto Restart function for C-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 problem resulting from this.

Safety cautions

Entrusted installation
Installation should be entrusted with after-sale
servicemen. Self-installation is likely to cause
water leakage, shock and fire, etc.

Installation should be done according to this
installation manual. Inappropriate installation
may lead to water leakage, shock and fire, etc.

Connection of the earth wire
The earth wire should not be connected to
gas pipes, water pipes, lightning rods or
telephone wires. Poor earth may lead to
shocks.

After-sale servicemen should take measures
to avoid refrigerant leakage.
Refrigerant leak may cause anoxia when
a certain density is reached. If the room
is small, make sure to have sound safety
measures to avoid anoxia accidents.

Installation site
The site must be firm enough to withstand the
weight of the air conditioner to prevent
falling.
During installation, if refrigerant leakage
occurs, ventilation measures must be taken.
When refrigerant meets with fire, hazardous
gas will be produced.
After installation, make sure that there is
no refrigerant leakage.
Refrigerant, if meeting with heaters and
stoves, etc in the room, may produce
hazardous gas.
The installation of the electric part should
be conducted by qualified professionals
and done according to the installation
manual. Special return circuit must be used.
Insufficient capacity return circuit and
inappropriate installation may lead to fire
accidents.
Specific cables should be used for the
wiring. To avoid external tension of the
cables, the terminals should be firmly fixed.
Inappropriate connection and fixture may
lead to fire accidents.

Electric leak breaker should be installed.
Without it, shock accidents may occur.
Do not install at places where inflammable gas
leak may occur.
Gas leakage may lead to fire accident.

In order to discharge the condensed water,
the installation of the drainpipe should be
done in accordance with the manual
instructions. The drainpipe should be treated
for heat isolation. Inappropriate treatment
may lead to water leakage in the room.

Test run
After indoor units are installed,all
cassettes hinded models should be
tested.when the units are confirmed
to be normal,other fitments can be
installed.
