5.1 Mechanical installation

Danger: Before starting work, make sure
that the pump has been disconnected from the
power supply.
Provide a weatherproof, frost-free, dust-free and
well-ventilated room for the installation. Choose
an installation site that is easily accessible.
Caution: Dirt can cause the pump to fail.
Flush the pipe system before installation.
Note: In the case of the Star-Z NOVA A
version, the stop valve and non-return valve are
pre-installed. In the case of the Star-Z NOVA
version, these valves have to be installed addi-
tionally.
1. Prepare the installation site so that the pump
can be installed without being exposed to
mechanical stresses.
2. Choose the right installation position - only as
shown in (Fig. A). The arrow on the back of the
housing indicates the direction of flow.
3. Release the union nut - unscrew it completely
if necessary.
Caution: Do not damage the housing seal.
Replace damaged seals.
4. Turn the motor head so that the Wilo-Con-
nector points downwards.
Caution: If the position is wrong, water
can penetrate and destroy the pump.
