Requirements on maintenance and notices:
1. If system will stay idle for long time, cover the collector with a nontransparent film and disconnect it
from the power supply to prevent overheating of the collector.
2. Check the system regularly to find out if it operates properly; check the manometer to know if the
pressure valve is normal (normally pressure should be at least 1 Bar) ; if the pressure value is under
standard, check if there is any leakage on the pipes; if not, antifreeze shall be refilled into the system.
3. If the system needs replace the antifreeze liquid, it shall be emptied first. The liquids in the pipes
shall be drained up so as to fill antifreeze into it. If liquid cannot be drained up from the system, dry it by
blowing the system with a blower; don’t stop blowing until the system is completely dry.
4. Check the low temperature resistibility of the antifreeze regularly
（
For the detailed interval, consult the
local antifreeze supplier
）.
5. Pull the lever of the relief valve monthly to flush the valve seat and valve clack; keep dirt and scaling
off its sealing surface since they would cause leakage or Open/Close failing. Check if the valve can be
opened or closed normally.

Collector should be mounted fully protected against lightning strikes. If there isn’t any lightning protect
facility,a lightning rod or grounding line is required. The following is the drawing for mounting the lightning
rod on a flat or sloped roof:
