Precautions for installation of domestic air energy water heater

Date:2020-02-26 Hits:

1. Air energy installation location

    First choice: In the enclosed balcony, the enclosed balcony is a semi-open space that can be controlled independently; the water heater can be used as an air conditioner in summer (suitable for lunch break) when installed in this position, and a fresh air blower replaces the air in winter, which is an excellent installation location. Customers with strong desires in the Northeast must install in this location.

    Second choice 1: Outdoor terraces. The terraces in front of and behind large houses are also very suitable for installing air energy, which is convenient and safe.

    Second choice 2: Air-conditioning unit. Generally, houses have air-conditioning units. A slight improvement on this position is also very suitable for installing air energy. If you encounter a narrower air-conditioning unit, you cannot install it.

    Second choice 3: Small platforms, beams and columns outside the wall, where water heaters are installed, and some reinforcement may be needed.

    Second choice 4: The roof platform, where the solar energy was originally installed, can be installed with air energy. Note that there must be hot and cold water pipes, and the power socket must have a waterproof box.

    Second choice 5: bathroom, kitchen, if the bathroom or kitchen is relatively spacious, it can also be installed in these places, but you must pay attention to the layout of drainage facilities.

    Final selection: wall-mounted installation, there is a certain risk of wall-mounted installation, customers try not to choose, the reason is that they may fall in shocks such as earthquakes; if the customer insists on wall-mounted installation,

    Preferential: The closest location of the kitchen under the same conditions is preferred. The hot water is used most frequently in the kitchen, followed by public toilets. The closer the distance is, the less cold water is. 50% of the hot water is used by the kitchen in one year.


2. There are drainage facilities

    The installation of air-energy water heaters has condensed water discharged during use, so the installation location must have floor drains, water ditches and other drainage facilities.


3. Installation location of the instrument

    The instrument, that is, the control panel, needs to be installed nearby to avoid rain; because most of the operation mode chooses the "economy mode", the control panel is actually rarely operated, and there is no need to install it in a very conspicuous position. It can be installed on the balcony or corridor wall. installation.


4. Water pipe layout

    The inlet and outlet pipes of air energy water heaters are preferably 25PPR pipes (commonly known as 6 in charge). Note that the screw thread of the water pipe is still 4 points; the air energy water heater is a central water heater, and the outlet pipe is actually a main pipe. "phenomenon. For customers who install the return water device, the diameter of the return pipe only needs to be 4 minutes.


5. Power socket

    The power socket is a three-pin plug with a wire diameter of 1.5 square meters (or more), preferably with a waterproof box.


6. Basic requirements for on-site installation:

    6.1. The bulk machine must be installed on site, so you must carry a vacuum pump, a spirit level, a copper pipe expansion interface tool, especially a vacuum pump, which is the key equipment.

    6.2. The coil and connecting pipe must be evacuated, and the vacuum degree should reach 550 mmHg and above; if refrigerant is used to drive the air inside the copper pipe, it will inevitably reduce the amount of refrigerant (the refrigerant is very expensive and manufacturers will not add more) and affect the heating efficiency , Will also pollute the environment.

    6.3. The level deviation of the host should be less than 5mm.


7. Test program:

    7.1. Connect the cold water pipe first, and the cold water pipe is connected to the water inlet at the position of the safety valve (the cold water pipe interface should be installed with an overhaul valve);

    7.2. Filling the water tank and filling the water tank is the most important link (filling must be completed before the hot water pipe is connected). After the hot water outlet has water flowing out (indicating that the water tank has been filled with water), close the valve and stop filling;

    7.3. Connect the hot water pipe and open the water inlet valve;

    7.4. Plug in the power cord and start running

    7.5. Check the water pipe wires, listen to the sound, check the fan, and observe the instrument. After running for 10 minutes, the test machine is completed.

8. Do not move the water temperature probe at will: the water temperature probe cannot be separated from the blind pipe for detecting the temperature of the water tank, so as to avoid overheating of the heater of the unit and damage to the unit.

9. The hot water temperature should be appropriate: When the hot water temperature is above 50 degrees, it must be mixed with hot and cold water to avoid scalding.

10. Selection of fuse: Don't use copper wire or iron wire instead, it may cause malfunction or cause fire.

11. Confirm the use power of the electrical equipment: the main power supply must meet the power requirements of the heat pump water heater, and the electricity use must meet the national civil/commercial use requirements. Otherwise, the unit will be damaged by over-voltage and under-voltage operation, or even fire.

12. Leakage protection switch: The customer should install a leakage protection switch with equal power and good grounding performance.
