■
Electrical installation must have dedicated lines and be installed by professional electricians. The electrical part
must be protected from moisture, otherwise it will cause electric shock, fire and other accidents.
■
The leakage protector must be set correctly. Leakage circuit breakers must be installed in accordance with
electrical codes, and incorrect installation may result in electric shock.
■
The power cord should not be pulled too tightly. Doing so can break the cable and generate heat, which can
lead to fire or other accidents.
■
Do not touch sharp edges and heat exchanger fins. Sharp edges and heat exchanger fins are harmful and
should be avoided.
■
It is forbidden to install the unit where it may leak flammable gases. If flammable gas leaks and accumulates
around the unit, explosions, fires, etc. may occur.
■
If the unit is installed in a hospital, telecommunications station or the like, take appropriate protective measures.
Inverters, self-contained generators, high-frequency medical equipment, and radio communication equipment may
cause the air conditioner to work abnormally or not.
■
Be careful when handling the product. If the weight of the product exceeds 20KG, it cannot be handled by one
person. It should be assisted by special equipment.
■
It is forbidden to directly control the operation and stop of the unit with the power switch and the electric gate.
Such erroneous operations can cause clicks or fires.
■
No unit is allowed to be installed near such places that are dirty, oily, salty, exposed to a large amount of sulfur
gas and where the unit parts may be subjected to corrosion, such as toilet vent, operation room vent and
sewage treatment equipment.
■
If the unit is operated below 0°C, it must be installed at a place at least 300 mm above the ground, so as to
avoid icing of unit base plate and to ensure the normal operation of the unit even though the snow reaches this
height; in addition, the unit shall be placed on a plane (with maximum deviation per meter of not more than 2 mm).
■
It is forbidden to change the setting value of the safety protection device. Failure to do so may result in fire,
explosion, etc.
■
If the wire harness wiring sequence is connected incorrectly, component and controller damage will occur.
Please check the cable sequence before powering on to avoid controller damage.
■
The unit must be warmed up for two hours for the first time. This is to protect the compressor. If the preheating
time is not met, the unit may report the oil preheating and the temperature barrier.
■
If the unit is running below 0 °C, it must be installed at least 300mm above the ground. This is to avoid the unit
chassis freezing, and to avoid the normal operation of the unit due to the thickness of the snow reaching this
height. It should be installed on a flat surface (maximum deviation should not exceed 2mm per meter).
■
Prepare protective equipment and installation tools. Protective equipment, including gloves, work clothes, etc.,
can prevent accidental personal injury.
■
It is forbidden to use fuses that exceed normal capacity. Replacing a fuse with a wire or the like will be a safety
hazard or cause a fire.
■
It is forbidden to short-circuit the safety device and force the unit to start. This can result in damage to the unit,
fire, explosions, etc.
■
It is forbidden to use other uses beyond the scope of its unit design. This machine is not suitable for storing
food, animals, plants, art, etc., otherwise the quality of these items will be degraded.
■
Before the unit is repaired and maintained, the unit must be stopped and the power supply must be cut off.
Otherwise, there will be consequences such as electric shock and accidental injury.
■
When the unit is deactivated for a long time, the residual water inside the unit must be exhausted. If the unit is
out of service for a long time, the water pipe should be filled with preservatives or the remaining water in the pipe
should be removed. Otherwise, the unit components may be cracked and leaked.
■
Do not place or hang any objects above the unit. Accidental injury can occur when an object is dumped or
dropped.
■
It is forbidden to operate the unit with wet hands. Otherwise it will cause an electric shock.
■
Do not touch the unit fan and other moving parts. Failure to do so may result in accidental injury.
■
If the unit is running abnormally, you must cut off the power immediately and get in touch with the dealer
Precautions for using R410A refrigerant
The system must be filled with liquid refrigerant. If a gaseous refrigerant is used to fill the system, the refrigerant
composition in the system will change and the performance of the unit may decrease.
CAUTION
