Push the wind shroud onto the water tank to plug the joint (Fig. D). 6. When installing the vacuum tubes, one tube should be installed on each side of the water tank first so that the water tank and bracket can be positioned as a whole. Notes 1. Check if the seal rings in the tank holes are all ready, if the sealing planes are clean, free of foreign bodies and breakage. 2. Put the wind shroud on the open end of the vacuum tube with the inclined plane downward and to a position about 10cm to the tube end. Before installing, wet the tube end with water to facilitate installation.

Any form of modification of the installation structure of the water heater may cause problems in use. 2. There are 5 ways for the heater pipeline to enter the house: flue, exhaust pipe, penetrating hole, special pipeline well for solar water heater, embedded bushing. Of which the first 3 are relatively popular. Before installing the pipeline, the installation personnel will discuss the entering way and installation position of the pipeline with you for your convenient use. During piping, the penetrating hole must have an adverse slope and be sealed properly to prevent rain and odor from coming into the house. 3. The overflow pipe must be fastened firmly and its indoor opening must be kept downward. The overflow water can be discharged directly into the sewer. The distance between the opening of the overflow pipe and the sewer plane should not be more than 15cm. Never hang the overflow pipe arbitrarily as splash of large amount of overflow water will damage articles in your house. 4. Never install valve in the overflow pipeline to ensure rapid, accurate transfer of Full-of-Water signal. 5. Check valves should be installed on the trunks of water supply and drain pipes that are connected with the tap water pipe to prevent back flowing of water in the tank. 6. When several water heaters are combined, the installation plan should be validated by a professional service person of Haier.
