Installation manual
Do not modify the length of the power supply cord or use
of extension cord, and do not share the single outlet with
other electrical appliances.
Otherwise, it will cause fire or electrical shock.
Carry out the specified installation work after taking into
account strong winds, typhoons or earthquakes.
Improper installation work may result in the equipment falling
and causing accidents.
The temperature of refrigerant circuit will be high, please
keep the interconnection cable away from the copper tube.
The power cord type designation is H07RN-F.
Equipment complying with IEC 61000-3-12.
If the refrigerant leaks during installation, ventilate the area
immediately.
Toxic gas may be produced if the refrigerant comes into the place
contacting with fire.
After completing the installation work, check that the
refrigerant does not leak.
Toxic gas may be produced if the refrigerant leaks into the
room and comes into contact with a source of fire, such as a
fan heater, stove or cooker.
The appliance is not intended for use by young children or
infirm persons without supervision.
Young children should be supervised to ensure that they
do not play with the appliance.
Don't install the air conditioner in the following locations:
There is petrolatum existing.
There is salty air surrounding (near the coast).
(Except for the models with corrosion-resistant function)
There is caustic gas (the sulfide, for example) existing in the air
(near a hot spring).
The Volt vibrates violently (in the factories).
In buses or cabinets.
In kitchen where it is full of oil gas.
There is strong electromagnetic wave existing.
There are inflammable materials or gas.
There is acid or alkaline liquid evaporating.
Other special conditions.
The insulation of the metal parts of the building and the air
conditioner should comply with the regulation of National
Electric Standard.
Acceptance and Unpacking
After the machine arrives, check whether it is damaged during
the shipment. If the surface or inner side of the machine is
damaged, submit a written report to the shipping company.
Check whether the model, specification and quantity of the
equipment conform to the contract.
After removing the outer package, please keep the operation
instructions well and count the accessories.
Refrigerant pipe
Check the model and name to avoid mistaken installation.
An additionally purchased refrigerant distributor (manifold
adapter and manifold pipe) must be used for installing the
refrigerant pipes.
The refrigerant pipes must have the specified diameter.
Nitrogen of a certain pressure must be filled into the refrigerant
pipe before welding.
The refrigerant pipe must undergo heat insulation treatment.
After the refrigerant pipe is installed completely, the indoor unit
cannot be powered on before performing the airtight test and
creating a vacuum. The air-side and liquid-side pipes must
undergo the airtight test and vacuum extraction.
Airtight test
The refrigerant pipe must undergo the airtight test [with 3.9
MPa(40kgf/
CM2
) nitrogen].
2. CONSTRUCTION CHECKPOINTS
CAUTION
The cooling&heating indoor unit is applicable for the
cooling&heating and the cooling only outdoor unit;the
heating capacity of the indoor unit will be effective only
when the indoor unit connect to the cooling&heating
outdoor unit.
This A/C is a kind of amenity unit. Don’t install it at the
place where for storing machine, precise instrument, food,
plant, animal, artwork or any other special used occasion.
Ground the air conditioner.
Do not connect the ground wire to gas or water pipes, lightning
rod or a telephone ground wire. Incomplete grounding may
result in electric shocks.
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric
shocks.
Connect the outdoor unit wires , then connect the indoor
unit wires.
You are not allowed to connect the air conditioner with the
power source until wiring and piping the air conditioner is done.
While following the instructions in this Installation manual,
install drain piping in order to ensure proper drainage and
insulate piping in order to prevent condensation.
Improper drain piping may result in water leakage and property
damage.
Install the indoor and outdoor units, power supply wiring
and connecting wires at least 1 meter away from
televisions or radios in order to prevent image interference
or noise.
Depending on the radio waves, a distance of 1 meter may not
be sufficient enough to eliminate the noise.
