• To realize the function of the air conditioner unit, a special refrigerant circulates in the system. The used
refrigerant is the fluoride R32, which is specially cleaned. The refrigerant is flammable and inodorous.
Furthermore, it can leads to explosion under certain conditions.
• Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm to the ozonosphere.
The influence upon the greenhouse effect is also lower. R32 has got very good thermodynamic features
which lead to a really high energy efficiency. The units therefore need a less filling.
• Before installation, please check if the adopted power is accordance with that listed on nameplate, and
check the safety of power.
• The unit shall contact with the supply mains by a full disconnection device under overvoltage category
Ⅲ .
• Before using, please check and confirm if wires and water pipes are connected correctly to avoid water
leakage, electric shock or fire etc.
• Don't directly expose the unit under the corrosive ambient with water or dampness.
• Never press the button with sharp objects to protect manual controller. Never use other wires instead
of special communication line of the unit to protect control elements. Never clean the manual controller
with benzene, thinner or chemical cloth to avoid fading of surface and failure of elements. Clean the
unit with the cloth soaked in neutral eradicator. Slightly clean the display screen and connecting parts to
avoid fading.
• The power supply line must be separated with the communication line.
◆ Safety notices for on-site installation
• Installation should be performed by qualified servicemen who have taken specialized training and
acquired corresponding certificates in accordance with relative laws, regulations and this manual,
otherwise it would lead to damage to the unit, water leakage, electrocution, or fire hazards etc.
• The unit should be installed on the smooth foundation capable of supporting the unit and fixed with
screw bolts. The foundation with inadequate strength would lead to leakage, turn-over or personal injury
or death.
• Special lines should be used for electric installation by qualified electricians. Lines with inadequate
capacity would lead to electrocution or fire hazards.
• Make sure each connector is properly tightened; otherwise it would lead to overtemperature or fire
hazards etc.
• When installation is finished, please check for the drainage lines, pipelines, and electric lines to prevent
water leakage, electrocution or fire hazards.
• The appliance is intended to be permanently connected to the water mains and not connected by a
hose-set.
• This equipment should be installed where the drainage system can work well. Never block the drain hole.
Improper drainage system would lead to drainage difficulty and make the unit suffer from malfunctions.
• When there is something unusual (like stinky smell) during installation or commissioning, please cut off
the main power at once and then contact the aftersales service center. This ongoing unusual condition
will damage the air conditioning unit and lead to electrocution or fire hazards.
• When refrigerant leaks, take corrective measures as soon as possible to prevent oxygen depletion by
increased refrigerant concentration.
