Monitoring Your System – Please Read Carefully
Once your system is fully operational, you can monitor it using two devices: the flow meter and
the temperature gauge. (See diagram on page 4 for location).
The flow meter is a visual site glass located near the top of the solar tank, and shows the current
flow rate of your system. With maximum sun, the circulation rate will be about 2.5 gallons per
minute. If there is no flow on a sunny day, or if there are excessive bubbles in the flow meter,
this could indicate a problem. However, if the system has reached high limit, indicated by the
temperature gauge being above 150 degrees F, it may have turned off automatically. For an
accurate reading, hot water should be turned “on” for a few seconds somewhere in the house to
move water from the solar tank past the temperature gauge.
The temperature gauge is located just above the solar storage tank, mounted on the “hot” pipe
returning to the solar tank from the solar collector (see diagram on page 4). The temperature
gauge shows the temperature of the heat transfer fluid as it is being heated by the sun. In order to
get an accurate reading, the pump must be in operation.
NOTE: This gauge does not tell you the
internal temperature of the potable water within the solar storage tank. The temperature within
the storage tank will be 20-40 degrees cooler than the temperature gauge reading.
When leaving for extended periods in the summer or winter, there is no need to switch your
system off. (See
Operation and Maintenance, page 34 and Troubleshooting, page 35 .)
You should check your flow meter and temperature gauge at least once a month.
In case of emergency call your installer:
