For your safety, please read through this manual carefully before
installation to minimize the risk of fire, property damage, personal
injury, or death. Ensure the solar hot water system is properly
installed in accordance with this manual before use.
INSTALLATION OR SERVICE IS REQUIRED TO BE PERFORMED BY
LICENSED PROFESSIONALS WHERE SOLAR, PLUMBING, AND
ELECTRICAL WORK IS REQUIRED.
The installer should be guided by the instructions furnished with
the tank, as well as local codes and utility company requirements.
Preference should be given to codes and requirements where they
differ from the furnished instructions. Always use the latest edition of
codes.
Additional publications which should guide the installer include:
Local, state, provincial, and national codes, laws, regulations, and
ordinances.
Introduction
Your water heater has an internal heat exchanger for use with solar
collectors. When there is not sufficient solar energy, the water
heater utilizes a backup system to provide hot water. In SE Series
models, the water heater has an electric heating element. (Refer to
Applications in this manual for piping examples of both models.)
Your system uses a circulation pump to circulate heat transfer fluid
(HTF) throughout a closed loop system. Closed loop propylene
glycol systems provide additional freeze protection for the solar
components.
