CAUTION
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℃, 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.
