Information regarding maintenance work
Danger
When working on electrical con-
nections, injuries may occur as a
result of electrical current if the
Stirling engine has not cooled
down. Contact with the Stirling
engine can also lead to burns.
■ Only work on the Stirling
engine when the head temper-
ature has fallen below 50 °C.
The Stirling head temperature
is displayed in parameter 8360
(see page 116).
■ Never move or shake the Stir-
ling engine if its electrical con-
nections have been disconnec-
ted or the control unit has been
removed.
Maintenance work on the Stirling engine
The Stirling engine is more or less main-
tenance-free. The Stirling generator is
maintenance-free. Ceramic materials
are used in the Stirling engine. If work
still has to be performed on the Stirling
engine, ensure that ceramic particles are
not released.
Commissioning, inspection, maintenance
■ Allow at least 7 min to elapse
after switching off the appli-
ance before touching the
capacitor terminals.
■ Only work on the Stirling
burner, the auxiliary burner and
the heating surface when these
have cooled down.
■ When working on components
containing water, ensure that
moisture does not enter the
control unit or the power supply
unit.
■ Never damage or open the Stir-
ling engine or subject it to
mechanical loads.
Danger
Fibre dust can result in a risk to
health.
Take appropriate safety meas-
ures when working on the Stirling
engine. Wear a P2 respirator.
Never damage or mechanically
work on the thermal insulation of
the Stirling engine. Observe the
stipulations of the Technical
Guidelines for the Handling of
Hazardous Materials (TRGS) [or
local regulations].
