Mechanical Installation

Installation site checklist
Never install the unit in an explosive or flammable environment.
Always refer to the local and national regulations, legislation, and codes in force regarding selection of
installation site, and water and power connections.
Keep the manual, drawings, and diagrams accessible for detailed installation and operation instructions. It is
important that the manual is available for equipment operators.
Ensure that the ingress protection rating of the Unit (IP 55, Type 1) is suitable for the installation environment.
Ingress protection. IP55 (type 1) rating can only be guaranteed if the unit is properly closed.
Make sure that there is no liquid on the unit before opening the control panel and plastic cover of the frequency
converter unit.
Ensure all cable glands and unused holes for glands are properly sealed.
Make sure that the panel and plastic cover of the frequency converter unit is correctly closed.
Device damage through contamination. Do not leave unit without the terminal box cover.
Remove scraps, dirty and solid parts from inside control panel and the frequency converter unit.

Unit installation

Install the unit according to the systems liquid flow.
Usually arrows on the pump housing show flow and rotating direction.
The standard rotating direction for the unit is clockwise (seen from fan cover). For more information contact
Service.
The unit must be installed according to Figure 7.
Always install a backflow-prevention device on the suction side.
Install the unit a well-ventilated room, allowing sufficient clearance (0.5 m) on all sides and front for
maintenance. Guarantee 0.5 m in height above the highest part.
Position the set on a level and sturdy surface.
It is recommended to install a closing valve immediately after the unit.
It is recommended to install a drain valve for testing if no tap has been provided near the unit.
Piping
The pipes that are connected to the set must be adequately sized (if possible, according to manifold diameter).
You can use either end of the manifold, but do not forget to plug the unused end.
Suction pipe and foot valve must be of sufficient size to prevent excessive flow resistance and the consequent
cavitation phenomena.
To prevent undue stress, expansion joints and suitable pipe supports should be provided (Figure 7). The weight
of the pipes and tanks increases when they are filled with water.
Before starting the set, make sure you have closed and tightened all the unused couplings.
