ROOF ASSEMBLY OF SOLAR COLLECTORS
20
INSTALLATION CHECK LIST
Once the installation is complete, it is important to check the following:
The outlet side of the collector array is between:

20 – 30 mm (for two solar collectors)
higher up the roof than the inlet side of the collector array and that the solar
hot outlet is higher than the hot sensor housing. If in doubt use a spirit level.
Maximum recommended total combined solar cold and solar hot pipe length
is not exceeded.
Solar cold and solar hot pipe work is insulated in accordance with the
installation instructions.
The pipe work at the connectors is orientated downward, below the collector
connection, to ensure complete drain back of the closed circuit fluid from the
solar collectors in an indirect closed circuit system.
The solar hot and solar cold pipes grade downwards with a continuous fall
of not less than 5° (1 in 10 grade) from the solar collectors to the storage
tank for an indirect closed circuit system. If in doubt use a spirit level.
Maximum height from the base of the storage tank to the top of the solar
collectors is not exceeded.
