Please note
To prevent equipment damage,
cover the collectors before any
work on the components of the
solar thermal system begins.
Mixing the heat transfer medium
with water reduces the frost and
corrosion protection. Only flush
the system with the specified
heat transfer medium. Never mix
"Tyfocor LS" with other heat
transfer media.
Checking the frost protection temperature and the pH value of
the heat transfer medium
Check the frost protection temperature
of the "Tyfocor LS" heat transfer medium
with a Viessmann antifreeze tester or the
manual refractometer in the solar service
case (accessory).
Checking the thermal insulation of the pipes
Check the thermal insulation of the pipes
for positioning and damage and adjust if
required.
Replace any damaged parts.

Electrically isolate the system (e.g. at a
separate MCB/fuse or the main isolator)
and safeguard against unauthorised
reconnection.
Check the pH value using the pH strip in
the solar service case (accessory).
Note
The thermal insulation of external pipes
must be resistant to temperature and UV
rays. The insulation must be protected
against attack from small animals and
birds (e.g. metal sheath).
