CASCADE 2
DOMESTIC SOLAR WATER
HEATING SYSTEM
INSTALLATION, OPERATION AND MAINTENANCE MANUAL
The Cascade 2 domestic water heating system has gone through an extensive design, technical and per-
formance review by the Solar Rating & Certification Corporation (SRCC). The installation of your Cascade
2 system is intended to be executed by properly licensed and experienced professional contractors in ac-
cordance with SRCC Standard OG-300, “Operating Guidelines and Minimum Standards For Certifying”,
and shall conform to applicable federal, state and local regulations, codes, ordinances and standards gov-
erning the installation of solar water heating systems.
The solar energy system described by this manual, when properly installed and maintained, meets the
minimum standards established by the SRCC. This certification does not imply endorsement or warranty
of this product by the SRCC.
OG-300 system certification is granted to SunEarth by the SRCC. It may not be used for any commercial
purpose without prior written consent of SunEarth. SunEarth must approve any deviation from the mate-
rials and methods described in this manual in writing.
The Cascade 2 Drainback solar water heating systems can be protected against freeze damage
to temperatures as low as -50ºF (-46ºC). This system should not be installed in areas within
the continental United States where the annual ambient temperature has ever fallen below
minus 50° Fahrenheit (-46° Celsius). The Cascade 2 Drainback system must be installed as
specified in this manual to have effective freeze protection at these low temperatures.
Freeze tolerance limits are based upon an assumed set of environmental conditions. Extended periods of
cold weather, including ambient air temperatures above the specified limit may cause freezing in exposed
parts of the system. It is the owner’s responsibility to protect the system in accordance with SunEarth’s
instructions if the ambient temperature approaches the specified freeze tolerance limit.
