Instruction:
1. Sending cold water after reducing the temperature in vacuum tube when first to transport water.
2. hot water tap, sprayer valve and upriver valve and downriver valve are in closure condition when no using. Upriver valve and downriver valve should be opened when watering.(others are closed)
3. Overflow pipe will outflow water after the water is full. At this time, please close upriver valve and open hot water tap for two minutes to free less water of water tank in order to outflow water after heating to loss heat.
4. Pleas test water temperature when bathing in order to prevent higher temperature hurting people. 5. Using fan heater to increase the temperature when the temperature in the room is low.
6. Adjusting cold and hot valve to the suitable temperature for bathing according to season, illumination and hydraulic pressure when adjusting water temperature.
7.please at once send water or many make vapour dry in the night or morning and make high temperature after using hot water in the daytime of summer. Then, water tube may crack..
8.after filling full water in the spring, summer and autumn, you must pay more attention to dry vapour if there is no use in continuous sunny days. Sending water should be in the night or the morning.(before the sun rising)
9、trying to avoid water heater to sunshine for a long time to affect its gasket ring, performance and service life of vacuum tube.
10.Having to check creepage protector, fuse, etc before heating with electricity. Filling water and plug power supply. Please do not heat without water and cut power after heating.
Stopping bathing with electricity!!
11.please do not use when there is thunder and rain. Keep water full in water tank when blowing typhoon.
12.making blowoff valve closure and opening water heater, then freeing water in upriver and downriver tubes before adding blowoff equipments.
| Common sense of solar energy：

一.Features of solar energy water heater
Solar energy water heater has very obvious advantages, such as, safety, cleanliness, saving energy, environmental protection, etc compared with general water heaters. This is why it can quickly occupy water heater market |
| 二.How choose and purchase solar energy water heater
Good products should have whole instruction, warranty card, marker and packing container. The appearance is beautiful and the structure is reasonable. The products should have perfect after-sale service guarantee. |
| 三.What size you choose water heater
Hot water of 35kg to 50kg(the temperature is about 45℃) is generally needed when bathing. The sun is not general energy and it can not produce hot water, so you need to choose water heater with double water dosage and reserve hot water and use it in rainy days. If it rains continuously, you can choose water heater with light and electricity to ensure using hot water in any time. |
| 四.What kind of pipeline should be chosen
The water heater always puts on top of buildings and has a certain of pressure with buildings, the temperature of hot water achieves 90℃, etc, so you’d better choose cross-linking or aluminum-plastic laminated tube or strong plastic hose. They have pressure resistance, high temperature resistance, low temperature resistance, etc. Thermal capacity of galvanized tube is big; hot loss is lot and easy to produce watermark, so it’s not better choose. |
| 五.How to check water heater
There is no sun shade in front of water heater and toward the south after finishing installing. Water heater can deviate about 10 degrees to the west. There is no leakage for water tank, pipeline, valve and tie-in. Insulated pipes should have no disjunction and bottom pour ladle. The position connecting vacuum tube and water tank is suitable. |
| 六.How to increase water temperature
1. Ensuring to reserve the temperature of upriver water pipes and downriver pipes.
2. Choosing cross-linking with small thermal conductivity
3. Choosing vacuum tube water heater with big capacity or pretty long, and keeping more hot water to increase basic water temperature.
4. Sending water after taking a bath in the night, and trying to keep water full in water tank to prevent high water temperature.
5. Free less water after filling in water to prevent hot water from overflowing in return pipes.
6. Water temperature will rise after shining in two days or half water of water tank shining in a day.
7. Using warm air blower to increase room temperature when water temperature is low for bathing. Add boiling water to increase temperature when tubbing.
8. Linking power after adding full water when using electric heating equipments, and cutting power when bathing.
9. The temperature will be low after using for a long time. Cleaning surface dusts of vacuum tube and baffle-board, and bottom sedimentary furring in vacuum tube. |
| Fault clearing ： |
| No flowing |
1. There is no water in water tank, and please use it after filling water full.
2. Tie-in of pipeline falls off and jams, and please reconnect dredge pipeline.
3. Upriver pipeline and downriver pipeline may be frozen in winter. They can automatically unfreeze after the sun rising in about three hours. It can add blowoff valve in cold areas.
4. Upriver valve and downriver valve make water. And there is no water in water pipelines for a long time. It can cause water to return.
5.Sprayer valve or hot water tap are not available, and they actually don’t open. |
| No sending water or no flowing in overflow pipes |
1. Stopping water or the water pressure is too low
2. Tie-in of pipeline falls off and destroys
3. Valves are not available and don’t be opened.
4. Overflow pipe falls off
5. Vacuum tube destroys |
| Water temperature is not high |
1. The time of sunlight is not enough for new water heater. It can be used in the second sunny day. 2. Upriver valve and downriver valve are broken or don’t screw down. Cold water continuously enter water tank to stop hot water flowing.
3. The sunshine is not good and radiant energy of sunlight is not enough. Please shine in one more day.
4. There is no preservation temperature in upper and bottom pipelines. The temperature in winter temperature is too low and hot loss is too serious.
5.Vacuum tube gets air leakage, and hot loss is too fast. |
| Water temperature is cold or hot |
1. The pressure of tap water is bigger than the pressure of hot water. Letting less cold water in, and then opening hot water and adjusting output of cold water.
2. Please don’t open other valves of tap water when bathing. |
| Water temperature is too high to adjust temperature. |
Water pressure is too low, and taking a bath when water pressure is high, or free water into bathtub to freeze or add cold water to adjust water temperature, and then taking a bath. |
| Ektexines of tap water pipelines are hot when opening upriver valve. ? |
Water pressure is too low; hot water returns. Please add water when water pressure is high. |
| Hydraulic discharge of sprayers is not big |
1. Water pressure of water pipes is too low and the differential pressure between water tank of water heater is very low and the pressure is low after mixing.
2. Eyelet of sprayers is small and less, or some impurities jam. Please change sprayers with large spraying capacity or clean sprayers. |
