Safety Instructions
!
COLLECTOR WARNING: A SOLAR COLLECTOR
GENERATED HEAT FROM SUNLIGHT. THIS LEADS
TO THE COLLECTORS AND THEIR CONNECTORS GETTING
VERY HOT, EVEN WHEN THEY ARE NOT FILLED. COVER
THE COLLECTORS WITH OPAQUE MATERIAL UNTIL THE
INSTALLATION HAS BEEN COMPLETED.
!
SAFETY VALVE WARNING: NEVER INSTALL ANY
VALVES OR SHUT-OFF DEVICES IN THE PIPING
BETWEEN THE COLLECTORS AND THE SAFETY VALVE. THE
SAFETY VALVE IS ACTIVATED AT 87 PSI.
NEVER SET THE SOLAR LOOP PRESSURE GREATER THAN
THE DHW WATER SUPPLY PRESSURE. IF THE POTABLE
WATER PRESSURE IS TOO LOW, A BOOSTER PUMP MAY
BE NEEDED TO ASSURE THAT IT EXCEEDS THE REQUIRED
SOLAR LOOP PRESSURE.
The solar system must not bypass auxiliary system safety
devices.
Check Valve
The Flowstar pump station is equipped with two check
valves to prevent heat loss from single pipe thermo-
siphoning between the storage tanks and the solar loop and
collectors.
Drain Valve
Install a drain valve at the lowest point of the system.
Expansion Tanks
The diaphragm-type expansion tanks are designed for
an operating pressure of 87 psi and are resistant to
deterioration from propylene glycol mixtures.
