Construction Checkpoints - Carrier Xpower Series Installation Manual

Do not modify the length of the power supply cord, use an
extension cord, or share an outlet with another electric
appliance.
Doing so may cause a fire or electric shocks.
Exercise caution during installation in poor weather.
Improper installation may cause an accident if the unit falls.
Keep cables away from the copper tube because the
temperature of the refrigerant circuit will be high.
The power cord type designation is H07RN-F.
Equipment complies 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 contact
with fire.
After completing installation, check that the refrigerant
does not leak.
Toxic gas may be produced if the refrigerant leaks into the
room and comes into contact with fire, such as a fan heater,
stove, or cooker.
CAUTION
The heating function of the indoor unit is available only
Caution:
when the indoor unit connected to the outdoor unit for cooling and
heating.
This A/C is an amenity. Do not install it at places where
machinery, precision instruments, food, plants, animals, or
artwork is stored.
Ground the air conditioner.
Do not connect the ground wire to gas or water pipes, lightning
rod, or a telephone grounding wire. Incomplete grounding may
result in electric shocks.
Install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric
shocks.
Connect the outdoor unit's wires before the indoor unit's
wires.
Do not connect the air conditioner to a power source until the
wiring and piping is completed.
Install and insulate the drainage pipe.
Failure to do so may cause leaks and damage.
Install the indoor and outdoor units, power supply wiring,
and connecting wires at least 1 meter from TV sets or
radios to prevent image or noise interference.
Depending on radio waves, a distance of 1 meter may not be
sufficient enough to eliminate noise.
Installation manual

Young children and elderly should not use the unit
unsupervised.
Young children should be supervised to ensure they do
not play with the appliance.
Don't install the air conditioner in the following locations:
Where there's petrol.
In salty air, e.g., coasts (except corrosion-resistant models)
Where there's caustic gas (e.g., sulfide near a hot spring).
Where voltage vibrations are excessive (e.g., factories).
In buses or cabinets.
In a kitchens with a lot of oil or gas.
Where there are strong electromagnetic waves.
Near flammable materials or gas.
Where there are acidic or alkaline liquids that could evaporate.
Other special conditions.
The insulation of metal parts in the building and the air
conditioner should comply with the regulation of National
Electric Standard.

2. CONSTRUCTION CHECKPOINTS

Acceptance and Unpacking
After the machine arrives, check whether it is damaged. If the
surface or inner side of the machine is damaged, submit a
written report to the shipping company.
Check whether the model, specifications, and quantity of the
equipment is as per the contract.
After removing the outer packaging, keep the instructions
securely and ensure you have all the accessories.
Refrigerant pipe
Check the model and name to avoid installing the wrong unit.
An additionally purchased refrigerant distributor (manifold
adapter and manifold pipe) must be used for installing the
refrigerant pipes.
The refrigerant pipes must be the specified diameter. The
refrigerant pipe must be filled with nitrogen at a certain
pressure before welding.
The refrigerant pipe must be heat insulated.
After the refrigerant pipe is installed completely, the indoor unit
cannot be powered on before performing the airtight test and
creating a vacuum. The gas-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
2
MPa(40kgf/cm ) nitrogen].
