Re-install the new drive in reverse order.
In order to replace the entire changeover valve, the
hydraulic connection for the valve [1] that is to be
replaced must be closed and bled accordingly.
After bleeding, you can loosen the three valve [1]
screw connections. After replacing one or both
valves [1], ensure that no air bubbles have formed
in the heat exchanger [2]. If there is air in the heat
exchanger [2], this can be bled manually via the
connections [3] in the upper part of the cooling
module for both sides. All screw connections must
be checked after replacing.
