Dimensions of pipe connections
All size of the connectors on the solar water heaters are 1/2 inch.

Precautions
1)
When using solar water heater in cold climate, please put insulation layer around the pipes which
outside the room.
2)
If you use electric heater, the person who install the electric heater must have electrician qualification.
And you need to use electricity leakage protection plug and should connect with ground wire.
7.
Max. working pressure
This type is non-pressurized type, but the solar water heater could bear the gravity of water inside.
8.
Installation Angle
It is common for collectors to be installed at an angle that corresponds to the latitude of the location.
Installing at an angle less than 20° is not recommended as the heat pipes perform best in the range of 20-70
degree While adhering to this guideline, an angle of la/-10°is acceptable, and will not greatly reduce
solar output.
Angles beyond this range may be used, but a decrease in heat output will result. An angle lower than the
latitude will enhance summer output, while a greater angle will enhance winter output.
9.
Wind and snow load
When installing the collector please consider the issue of wind resistance and the resultant stress on the
attachment points. the standard frame is designed to withstand wind speeds of up to
100km/h and 30cm
snow accumulation without damage. For the areas with possibility for high winds, additional reinforcement
of attachment points may be required and can easily be supplied by your local installers.
