TENESUN KFXRS-80IIP/A Inverter Commercial Hot Water Heat Pump Unit

TENESUN air source heat pump water heaters are mainly composed of four major components: compressor, evaporator, condenser, and expansion valve. Its working process consists of four steps: First, the evaporator absorbs heat from the air, causing the refrigerant to evaporate into a gaseous state; then, the compressor compresses and heats the gaseous refrigerant, forming a high-temperature, high-pressure gas; next, the condenser transfers the heat from the gas to the water, heating the water; finally, the expansion valve reduces the pressure of the refrigerant, causing it to return to a liquid state, completing the cycle. Inverter technology regulates the compressor speed to provide heat on demand, avoiding energy waste caused by frequent starts and stops, and extending the equipment's lifespan.

Operating Instructions

Before starting, check the power supply, water lines, and unit status to ensure there are no abnormalities;
Start the unit and observe whether the operating parameters are normal;
Adjust the water temperature as needed, but do not set the water temperature too low or too high;
Regularly record operating data for maintenance and analysis.

Precautions

The installation location must be well-ventilated and protected from direct sunlight;
Take necessary precautions against freezing in low-temperature environments during winter;
Regularly clean the pipe filter and remove foreign objects from the external fins of the heat exchanger to maintain efficient operation;
Non-professional person should not disassemble the unit without authorization;
Drain the system of water when it is not in use for an extended period.

Proper operation and maintenance can extend the unit's lifespan and improve energy efficiency. Users should strictly follow the instructions in the manual and contact professional people immediately if any abnormalities occur.
