matches the direction of flow of the liquid.
1. Mount the product in such a way that the liquid can escape via the dis-
charge opening without obstructions.
2. Mount the product to the pump line.
- A straight connection line with a maximum length of 1 m may be
installed between the product and the heat generator.
- The cross section of the connection line must correspond to the cross
section of the inlet of the product.
3. Tighten the connections with a maximum tightening torque of 18 Nm
when making the connections.
- Excessive tightening torque can cause cracks in the material which can
lead to leaks.
