Check the safety valve:
■
Response pressure
■
Correct installation, with discharge pipe
Checking the electrical connections
Check the tightness of the electrical plug-in connectors
and cable grommets
;
check cables for damage.
Filling and flushing the solar thermal system and checking for leaks
!
Please note
Filling and commissioning the solar thermal sys-
tem without first safeguarding the heat transfer
results in thermal stress.
Cover the collectors and keep them covered
until the heat transfer has been regulated.
■
Accessories for flushing and filling the solar thermal
system:
–
Flushing and filling facility
(filling trolley and
charging station)
These contain a high speed pump with a high
pump rate, a filter and a container for heat transfer
medium.
–
Fill valve set
, consisting of shut-off valve, drain
valve and fill valve.
■
Flush the solar thermal system with heat transfer
medium. Otherwise there is a risk that residual water
from flushing may become mixed with the heat trans-
fer medium. This would alter the properties of the
heat transfer medium.
■
Flush brazed copper pipes very thoroughly. Any
residual scale may compromise the operation of the
solar thermal system.
