Isolation Valves
Isolations valves must be installed for installation of the solar thermal system. These valves will be ball
valves and will be on the incoming mains water line and supply line to the fixtures as seen in the system
diagram in Section 3.1.
4.3.5
Check Valve
A check valve must be installed for installation of the solar thermal system. The valves insure water does
not thermosyphon in reverse to the house. Failure to install the check valve will greatly reduce the
operation of the system. As seen in the system diagram in Section 3.1
4.3.6
Thermostatic Mixing Valve (Anti-Scald Valve)
A thermostatic mixing valve must be installed in most jurisdictions to minimize the risk of scalding from
extremely hot water supplied by the Solar system. The installation shall conform to the plumbing code
adopted by the authority having jurisdiction or, in the absence of such code, the International Plumbing
Code. As seen in the system diagram in Section 3.1.
4.3.7
Pressure Regulating Valve
A pressure regulating value must be installed in the system to ensure the equipment is protected from
pressure building in the system. Failure to install the pressure regulator valve can result in pressures
exceeding warranty of the components. Ensure Pressure is set below system limits. As seen in the
system diagram in Section 3.1.
4.3.8
Drain Valve
A drain valve should be installed in the system for ease of servicing. Location of the drain valve should
be at the lowest point in the system. As seen in the system diagram in Section 3.1.

This system contains hot surfaces and fluids. Please exercise extreme caution during start up,
maintenance and decommissioning.
•
Avoid touching any surface before taking its temperature as pipes and surfaces of

•
Prior to draining any fluid ensure that fluid can be discharged to a safe
location.
•
Fluid may be extremely hot and under high pressure. In certain circumstances there may even
be steam in the system.

When working near the electrical connection ensure it is turned off at the
breaker. Ensure that all electrical connections are secure and have been
installed by a trained professional.
This system is intended for use with fresh, potable water only. No other fluid shall be used that would
change the original classification of this system. Unauthorized alterations to this system could result in
a hazardous health condition.
