Only operate the bleeding valve if the temperature of the heat transfer fluid is < 140° F.
When bleeding the system, the collectors must not be hot! Cover the collectors and, if possible, bleed the system in
the morning.
See Material Safety Data Sheet on page 45 for safety information.
Check heat transfer fluid
The heat transfer fluid must be checked every two years with regard to its antifreeze and pH value.
- Check antifreeze using antifreeze tester and replace or refill if necessary!
Target value is ca. - 77° F and - 22° F depending on climatic conditions.
- Check pH value with a pH indicator rod (target value approx. pH 7.5):
If the limit pH value is less than ≤ pH 7, replace the heat transfer fluid.
Maintenance of the collector
The collector or the collector array must be inspected visually, once a year, for any damage, leaks and
contamination. Additional recommendations on operation and maintenance can be found in the supplier's general
documentation and instructions on commissioning and maintenance.
Connecting the collectors to one another
The collectors must be connected to one another and/or to the connection pipes using the supplied connectors.
When tightening the union nuts and/or compression fittings, always balance (counter) the torque* with a pipe wrench
or another spanner to prevent damage to the absorber.
Do not run the solar collector(s) without a Pressure Relief Valve, safety valve in the system to avoid over pressure in
the solar circuit.
Warning: Freeze tolerance limits are based upon an assumed set of environmental conditions.
Warning: If the freezing point of the fluid in an exposed part of the system is above the freeze tolerance
limit specified for the system: Extended period of cold weather, including ambient air temperatures
above the specified limit, may cause freezing in exposed parts of the system. It is the owner’s
responsibility to protect the system in accordance with the Supplier’s instructions if the air temperature is
anticipated to approach the specified freeze tolerance limit.
