4 Principle of operation

4.1 Application

The pump is intended for pumping potable or

process water in a circulation system.

4.2 Functions

Valves The Star-Z NOVA A and Star-Z NOVA C versions

are equipped with a non-return valve (1) on the

pressure side and with a stop valve (2) on the suc-

tion side.

When exchanging the motor head (3), it is suffi-

cient to cut the power by unplugging the con-

nector (5) and to close the stop valve at the

rotating slot (4). The motor head can then be sim-

ply unscrewed >Page 9.

5.1 Mechanical installation

Installation site Provide a weatherproof, frost-free, dust-free and

well-ventilated room for the installation. Choose

an installation site that is easily accessible.

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 indi-

cates the direction of flow.

Danger: Before starting work, make sure

that the pump has been disconnected from the

power supply.

Caution: Dirt can cause the pump to fail.

Flush the pipe system before installation.

Note: In the case of the Star-Z NOVA A

and Star-Z NOVA C versions, 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 additionally.
