1. Installation in the following places may lead to water heater failure:
1) full of oil
2) humid
3) saline areas of the seaside
4) sulfurous gases (sulfuric hot springs)
5) high-frequency facilities, such as radio equipment, candlestick machines and medical equipment
6) special environmental conditions
2.
6)Special environmental conditions
2, the installation of water inlet pipe, must require the installation of check valves and correctly installed in accordance with the arrows on the valve body, such as poor water quality or excessive impurities in the water must be installed with a Y filter and other filtration devices.
3, the installation of circulating heating pipe will be the outlet of the water tank and the host of the water inlet with PPR pipe or aluminum-plastic pipe connected to the exhaust valve must be installed between.
4, pipe layout to minimize the length and unnecessary bending, reduce the pressure of the water system and heat loss, each water pipe and joints should be good insulation to avoid heat loss, resulting in increased power consumption of the host.
5. If there is a wall between the water tank and the outdoor mainframe, a φ70 pipe shall be opened on the wall, and the hole shall be slightly inclined to the outer side and put on the wall sheath on both sides.
6, the installation of safety valves; safety valves should be installed in accordance with the installation schematic, it is strictly prohibited not to install or replace the location of the installation.
7. Installation of drain/dirt valve; for the convenience of maintenance and drainage, it is recommended to install a drain/dirt valve, which can also be blocked with a plug.
8, water and leak detection; water connection is complete, open the tap water inlet valve, open the water tank valve and hot water pipe on any faucet to start adding water until the hot water faucet water overflow and then close the faucet, water storage leak detection to ensure that there is no leakage of connecting pipelines can be. Outdoor unit: The main unit can be installed on the ground, roof, balcony, special platform or any other place that is easy to install and can withstand the operating weight of the main unit. It can also be fixed on a solid external wall with mounting bracket (not hollow brick wall, such as external wall insulation needs to increase the length of expansion bolts).
Second, the installation of the host
1, choose a well-ventilated, smooth exhaust installation place, should not be installed in the following 50m confined space, so as not to affect the host from the air heat.
2, do not install the host in a polluted, dusty place.
3, the host should be free of strong heat sources and other equipment around the exhaust port of corrosive and flammable gases.
4, outdoor host and the surrounding walls or other objects placed between the distance shall not be less than the spacing indicated in the following chart
5, the host is placed on the roof, should pay attention to the direction of the wind, to avoid the direction of the host exhaust direct headwind; and there should be a good lightning protection measures.
6. If the mainframe is installed on the floor, it should avoid strong winds as much as possible, and it must be installed on the foundation with a height of 150㎜ or more, and ensure horizontal installation. Add 10mm~20mm rubber shock absorbing pads between the main unit and the foundation. 7. The mainframe should be installed in a place close to the power supply and water source, so as to facilitate wiring and piping.
8, the host and the hot water tank as close as possible, the distance should not be greater than 5m, the host and the height difference between the heating tank shall not be greater than the head of the machine.
9, near the host should be used for the discharge of condensate produced in the process of work downpipe.
10, near the host should be preset with the host power to match the independent socket.
11, easy to install and operate, strong winds do not blow and dry ventilation
12, can withstand the quality of the outdoor unit, the horizontal installation of the outdoor unit, and will not increase the noise and vibration
13, do not place any obstacles that may lead to heat dissipation of the air is blocked
14, in the summer for a long time in a strong sunshine, please install the awning Water tanks . .
Three, the installation of the water tank
1, the water tank can be installed in the outdoor balcony, flat roof, ground or indoor kitchen, bathroom and other locations, should be installed as close as possible to the point of water use and the location of the host of the heat pump in order to reduce the heat loss of piping, and at the same time, should be installed in the place where the water can be drained.
2, water tanks using advanced polyurethane foam insulation technology, but taking into account the heat loss, or should be placed as far as possible in an unventilated indoor location.
3, the water tank must be mounted upright, can also be used to mounting brackets fixed to a solid external wall (non-hollow brick wall, such as the need to do external wall insulation to increase the length of expansion bolts). Installation base must be solid, solid, load-bearing capacity should be greater than the running weight of the water tank more than twice.
4, such as outdoor host installation of the ground, the water phase of the installation location in the 2 ~ 3 floors above the need to increase a pressurized water pump.
5, the water tank must be installed one-way check valve (has been equipped, installed in the cold water make-up pipe), has changed the water tank maintenance treatment.
6, the use of tap water and the water tank is always open to ensure the supply of water in the tank.
7, no water in the tank or tap water stops, do not use the machine, so as not to cause damage to the machine.
8, the water tank water temperature is relatively high, do not use directly, require hot water and cold water mixing valve connected to the hot water point of use, the use of appropriate adjustment of the water temperature, in order to ensure the safety of human beings.
9, around the water tank should leave more than 500 ~ 600 mm installation and maintenance space.
I hope the above will help you.
