Precautions on pipeline installation
1. Any alteration to the structure of the solar water heater may cause problems in use.
2. There are five ways to connect the water pipe to the room: flue, vent hole, through-hole in
the wall, pipe well for solar pipes and embedded sleeves, wherein the former three types
are commonly used. Before installation, the installation staff will consult the entry form and
installation location of the pipe in a comprehensive way and in consideration of your
convenience. A slope in the through-wall must be ensured during pipeline layout, and
sealing shall be guaranteed to prevent the entry of rain or odors.
3. Keep the smoothness of the air pipe to prevent the blockage of impurities, which may lead
to collapse and deformation of the water tank under suction when using water.
4. To avoid the return of water in the tank, a non-return valve shall be installed at the joint of
the water upward/downward pipes and the tap water.
5. The installation project should be confirmed by our professional service personnel when
installing several sets of the series of the products.
