SYSTEM MAINTENANCE

HEAT TRANSFER FLUID (HTF) QUALITY

The chemical composition of the HTF may change over time. The HTF quality should be monitored on a periodic basis – at least annually. After summer and before any chance of the first freeze is an ideal time. A drop in ph can indicate the system has been stagnating frequently. The cause should be determined and corrected.

To test the pH level, use a digital ph tester or tight range litmus paper. Remove a small sample of the fluid from the airstop on the pump station. The pH should be between

8.1and 12.0. Fluid with pH between 7.5 and 8.1 can be conditioned by your contractor using an inhibitor boost. Fluid with pH above 12.0 or that is dark, dirty or has an acidic smell should be replaced.

PIPING AND EXTERNAL INSULATION

On an annual basis, all piping should be checked for leakage at joints, and unions. Any damaged external insulation should be repaired or replaced.

WIRING AND CONNECTIONS

On an annual basis, check wiring and connections, including sensor wiring and splices. Look for signs of overheating, discoloration, corrosion or loose connections. Any damaged wiring should be repaired or replaced.

FLUID LEAKS

If you detect a glycol or water leak, or the glycol loop pressure drops unexpectedly, contact your installation contractor immediately to diagnose the problem and recharge the system.

SOLAR PANEL CLARITY

If you live in a dusty climate, once a month wash off dirt that settles on the solar panel glass. Clean glass allows the solar panel to maintain a high level of thermal performance.

EXPANSION TANK

Annually check condition of the solar expansion tank. Check to see if it is waterlogged by quickly pressing schrader valve stem at bottom of the tank. You should get a quick burst of air. If fluid is discharged, the tank may be waterlogged and need replacement. Contact a qualified solar installer if the tank needs replacement.

VACATION

For extended periods with no hotwater usage such as vacation it is recommend that the max. tank temperature (S MX) in the solar control be set to 120°F. This maximizes the storage capaicity of heat build-up during the day using the CMX function for maximum collector temperature and will aid in preventing breakdown of the heat transfer fluid due to overheating.
