Running should only be performed by qualified personnel with experience in installations of this type. Carefully read hydraulic and electrical circuit installation. Check all your settings – microcontroller, PSL relays, PSH relais settings. Check details of cooled and cooling liquid circuits.Do not start the pump until the system has been filled with liquid and vented. Furthermore, the required minimum inlet pressure must be available at the pump inlet. The system cannot be vented through the pump.Checking and adjustment of the coolant and cooling liquids circulation systems - Check valves condenser and evaporator circulation system (if the system provides the flow switch). - Turn on the systems pumps. - Check the direction of rotation of the pumps.Note: When the wrong direction of rotation may trigger the flow switch and the pump stops (if the system provides the flow switch). If the pumps do not run, check the switch.
