Air-to-water Heat Pump
5
NOTE
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 operate the unit with wet hand, and don’t allow children to operate the unit.
The On/off in the instruction is for the operation to on and off button of PCB for users; cut off power
means to stop supplying power to the unit.
Don’t directly expose the unit under the corrosive ambient with water or dampness.
Don’t operate the unit without water in water tank. The air outlet/inlet of unit cannot be blocked by
other objects.
The water in unit and pipeline should be discharged if the unit is not in use, to prevent the water
tank, pipe line and water pump from frost-cracking.
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 cord must be separated with the communication line.
Any person who is involved with working on or breaking into a refrigerant circuit should hold a
current valid certificate from an industry-accredited assessment authority, which authorizes their
competence to handle refrigerants safely in accordance with an industry recognized assessment
specification.
Servicing shall only be performed as recommended by the equipment manufacturer. Maintenance
and repair requiring the assistance of other skilled personnel shall be carried out under the supervision
of the person competent in the use of flammable refrigerants.
