Haier 1U125S2SN1FA Installation Manual page 5

When service panels are removed, live parts can easily
be touched by accident, Never leave the unit unattended
during installation or servicing when the service panel is
removed.
DANGER: DO NOT TOUCH PIPING AND INTERNAL
PARTS
Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.
Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping
and internal parts time to return to normal temperature
or, if you must touch them, be sure to wear protective
gloves.
Warning:
Ask your dealer or qualified personnel to carry out
installation work. Do not install the machine by yourself.
Improper installation may result in water leakage, electric
shocks or fire.
Perform installation work in accordance with this installation
manual.
Improper installation may lead to water leakage, electric
shocks or fire.
The equipment is not intended for use in a potentially
explosive atmosphere.
For 1UH series units only.
For year round cooling applications with low indoor humidity
conditions, such as Electronic Data Processing rooms,
contacet yout dealer or see the engineering databook or
the service manual.
Consult your local dealer regarding what to do in case
of refrigerant leakage. When the unit is to be installed in
a small room, it is necessary to take proper measures so
that the amount of any leaked refrigerant does not exceed
the concentration limit in the event of a leakage. Otherwise,
this may lead to an accident due to oxygen depletion.
Be sure to use only the specified accessories and parts
for installation work.
Failure to use the specified parts may result in water
leakage, electric shocks, fire, or the unit falling.
Install the unit on a foundation that can withstand its
weight.
Insufficient strength may result in the fall of equipment
and causing injury.
Carry out the specified installation work in consideration
of strong winds, typhoons, or earthquakes.
Improper installation work may result in accidents due to
fall of equipment.
Make sure that all electrical work is carried out by qualified
personnel according to the applicable legislation and this
installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or improper
electrical capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or fire.
Make sure that all wiring is secure, using the specified
wires and ensuring that external forces do not act on the
terminal connections or wires.
Incomplete connection or fixing may cause a fire.
When wiring between the indoor and outdoor units, and
wiring the power supply, form the wires so that the
fronstside panel can be securely fastened.
If the frontside panel is not in place, overheating of the
terminals, electric shocks or a fire may be caused.
If refrigerant gas leaks during installation work, ventilate
the area immediately.
Toxic gas may be produced if refrigerant gas comes into
contactwith fire.
After completing the installation work, check to make
sure that there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into
the room and comes into contact with a source of fire,
such as a fan heater, stove or cooker.
When planning to relocate former installed units, you
must first recover the refrigerant after the pump down
operation.
Never directly touch any accidental leaking refrigerant.
This could result in severe wounds caused by frostbite.
Be sure to install an earth leakage circuit breaker in
accordance with applicable legislation. Failure to do so
may cause electrical shock and fire.
Caution:
Earth the unit.
Earthing resistance should be according to applicable
legislation.
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete earthing may cause electric shocks.
Gas pipe.
Lgnition or explosion may occur if the gas leaks.
Water pipe.
Hard vinyl tubes are not effective earths.
Lightning conductor or telephone earth wire.
Electric potential may rise abnormally if struck by a
lightning bolt.
Install drain piping according to this installation manual
to ensure good drainage, and insulate the pipe to prevent
condensation.
Improper drain piping may cause water leakage, and
make the fumitures get wet.
Install the indoor and outdoor units, power wire and
connecting wire at least 1 meter away from televisions
or radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter
may not be sufficient to eliminate the noise.)
Do not rinse the outdoor unit, This may cause electric
shocks or fire.
Do not install the unit in places such as the following:
Where there is mist of mineral oil, oil spray or vapour
for example a kitchen.
Plastic parts may deteriorate, and cause them to fall
out or water to leak.
Where corrosive gas, such as sulphurous acid gas,
is produced.
Corrosion of copper pipes or soldered parts may cause
the refrigerant to leak.
