Precautions
For safety reasons you should only fill the collectors when there is no direct irradiation from the sun (covering the
collectors can be an option). Especially in regions exposed to frost, for flat plate collectors you should use a mixture
of anti freeze with water (40% anti freeze). The solar thermal system should be filled and commissioned within one
week of installation, because heat build-up in the collector array can damage the flat gaskets in empty systems. If
this is not possible, the flat gaskets should be replaced before commissioning to prevent leakage.
Attention : Anti freeze that is not premixed must be mixed with water prior to charging the system
Recommended antifreeze for flat plate collectors – FHWM-GY-50005
25% antifreeze / 75% water mix - freeze point 14°F
40% antifreeze / 60% water mix - freeze point -5°F
50% antifreeze / 50% water mix - freeze point -25°F
It may not be possible to completely empty collectors one they have been filled. For this reason collectors exposed
to frost should only be filled with a distilled water/antifreeze mixture, also for pressure and function tests.
Alternatively, the pressure test can also be carried out using compressed air and leak detection spray.
Installing the temperature sensor
The temperature sensor should be installed in the sensor sleeve nearest to the collector array flow. To ensure
optimal contact between the sensor and the surrounding environment, the gap between the sensor sleeve and the
sensor element should be filled with a suitable conducting compound. All materials used for installing temperature
sensors (sensor element, conducting compound, cables, sealing and insulating materials) must be suitably
temperature resistant (up to 482° F).
Operating pressure: The maximum operating pressure is 145 psi.
Bleeding
The system must be bled:
- When commissioning the system (after filling the collectors)
- 4 weeks after commissioning
- When necessary, e.g. if there are malfunctions
Warning:
Risk of scalding due to steam and hot heat transfer fluid!
