I have been doing Jingmeirun air energy for 8 years, and my installation experience is as follows:
Choose a location that is ventilated and sunny.
A frame should be welded below the air source, 20-30 cm above the ground, to facilitate the discharge of defrost water.
PPR pipes of 5p-8p should be made of DN40 or above, iron pipes should be made of DN32 or above, and pipes above 10p should not be lower than the air outlet. All cut-off doors should be of large aperture and large flow (same caliber as the pipes) ).
The water pump uses a centrifugal pump or a multi-stage pump. (When the water pump inlet is smaller than the pipe diameter, the water inlet and outlet should be the same as the pipe diameter.) The variable frequency pump needs market inspection due to its short time.
After installation, check the temperature difference between the inlet and outlet water. The temperature difference is within 3- 5 degrees Celsius is normal. If the temperature difference is large, a bypass valve should be installed on the inlet and outlet pipes and a cut-off door should be used to control the water flow until the temperature difference is normal.
The terminal system must be equipped with a filter. After installation, clean the filter once every two days during the initial operation, and clean it 5 times continuously.
When connecting the power supply, the live wire and neutral wire must be connected to the corresponding wiring port. When selecting a gate, use a circuit breaker instead of a leakage switch.
It is necessary to add softened water to the air. During the heating period, if no one lives in the home or sometimes there is, sometimes there is not, water must be drained or antifreeze must be added (corrosion or freezing damage is not guaranteed).
It is recommended to use 250-550 watt centrifugal pump or multi-stage pump for 5p 6p, 370-550 watt centrifugal pump or multi-stage pump for 8p, 550-750 watt Lingxiao brand multi-stage pump for 10p and 750 watt for 15p. Lingxiao brand water pump with a lift of 27 watts
If the air energy connection cable is more than 50 meters, the cable should be doubled in thickness and the voltage and current should be tested before starting the compressor. After starting the compressor, check whether the voltage and current are normal
p>Cables should be copper cables (those using aluminum wires must use copper-aluminum noses)? Note: It is strictly forbidden to tilt the air during loading and unloading?
The working voltage must not exceed 10% of the standard voltage.
(Too high will damage electrical components, too low will cause poor performance)
Clean the fins once a year for household machines and twice a year for commercial machines (otherwise the heat exchange area will be reduced)
