The water connection pieces must be engaged in the retain-
ing plate before installing it in the heater. The locking lug
must be engaged in the connection piece as shown.
Engaging is carried out mechanically at Webasto, which is
why the entire unit, consisting of the retaining plate and the
connection piece, must always be ordered.
IMPORTANT
The locking lug must be engaged in the connection piece,
as otherwise leaks and a loss of coolant can result. A later
angle bracket adjustment is not permissible with the con-
nection piece engaged.
1. Lay new O-rings (B) in the heat exchanger (H).
