FLUID SAFETY LABELING (cont):
Valve “E”
– the label is affixed to
the tempering valve.
This valve is used to limit the
temperature of the water to the
fixtures in the dwelling to prevent
scalding.
Sight Glass
– this label is affixed
to the base of the sight glass on the
drainback tank.
The sight glass is used as a means
by which an observer can easily
identify that the system is operating
properly.
Valve “F”
– the label is affixed to
the isolation valves.
These valves are used to isolate the
solar system for repair and/or
maintenance. These valves are
normally open during system
operation.
Freeze Protection
– this label is
affixed to the collector return line
at the base of the drainback tank.
Manual intervention is required as
a secondary precaution to protect
components from freeze damage,
when air temperatures fall below
-60° F (-51.1°C).
Tank Drain
– this label is affixed
to the tank drain valve at the base
of the water heater.
This valve is to be used only as
directed in the water heater
owner’s manual or as directed in
this manual. Power should be
disconnected, at the circuit
breaker, prior to service.
WARNING / HOT
– labels are
affixed to the collector return line
at the drainback tank, the hot water
supply line from the water heater
and on all system components that
could present a safety hazard due to
high temperatures.
NOTE: The fluid safety labeling, as described above, is intended as a
means of identification for the homeowner and/or service personnel.
Removal of these labels could result in personal injury.
