
Allow the unit to cool down for at least ten minutes be-
fore removing the cover.
This should allow hot surfaces inside the unit to cool
down sufficiently.
 Loosen the four threaded bolts in the corners of the
cover which connect the cover to the chassis.
 Carefully pull the cover forwards (approx. 5 cm) from
the chassis.
The PE conductor connection between the cover and
the chassis is located o the right-hand side, around
half-way up.
Caution!
The cooling unit will only be stable as
long as the cover and chassis are con-
nected. For this reason, be sure to brace
the chassis, in particular, to stop it falling
over before removing the cover.
Caution!
After removing the cover, there is a risk
of burn injuries from hot component sur-
faces inside the unit.
