When water flows without air, close the tap. 4. Open the highest tapping point in the installation, preferably a shower. 5. Adjust the pressure setpoint to the required pressure by means of the buttons. See section 4.3 How to set the correct pressure. 6. Close the tapping point. Startup has been completed. Fig. 9 Priming the pump Carry out the electrical connection according to local regulations. Check that the supply voltage and frequency correspond to the values stated on the nameplate. DANGER Electric shock Death or serious personal injury - Switch off the power supply before starting any work on the product. Make sure that the power supply cannot be accidentally switched on. DANGER Electric shock Death or serious personal injury - The pump must be earthed. - The pump is supplied with a grounding conductor and grounding-type attachment plug. To reduce the risk of electric shock, be certain that the pump is connected only to a properly grounded, grounding type receptacle (protective earthing). - If national legislation requires a Residual Current Device (RCD), a Ground Fault Circuit Interrupter (GFCI), or equivalent in the electrical installation, this must be type B (according to UL/IEC 61800-5-1) or better, due to the nature of the constant DC leakage current. If the power supply cable is damaged, it must be replaced by the manufacturer, his service agent or similarly qualified persons in order to avoid hazard. We recommend that you fit the permanent installation with a residual-current circuit breaker (RCCB) with a tripping current less than 30 mA. DANGER Electric shock Death or serious personal injury - Check that the power plug delivered with the product is in compliance with local regulations. - Make sure that the pump is connected only to a properly grounded, grounding-type receptacle (protective earthing). - The protective earth of the power outlet must be connected to the protective earth of the pump. The plug must therefore have the same PE connection system as the power outlet. If not, use a suitable adapter. The electrical connection must be carried out by an authorised electrician in accordance with local regulations. DANGER Electric shock Death or serious personal injury - The pump must be connected to an external main switch with a minimum contact gap of 3 mm (0.12 inch) in all poles. Do not start the pump until it has been filled with liquid. If the suction depth exceeds 6 m (20 ft), it may be necessary to prime the pump more than once. Always tighten priming and drain plugs by hand.TM06 4204 1615 English (GB)7 4.3 How to set the correct pressure The pump can be set to provide a water pressure between 1.5 to 5.5 bar (22 to 80 psi) at intervals of 0.5 bar (7 psi). The factory setting is 3 bar (44 psi). See section 3.2 System sizing. 4.3.1 Boosting from a well or a tank If you are boosting from a well or a tank, make sure not to set the pressure setpoint too high. The difference between the inlet pressure and outlet pressure must not exceed 3.5 bar (51 psi). Fig. 10 Boosting from a well or a tank 4.3.2 Boosting from the mains The pressure settings 4.5, 5.0 and 5.5 bar (65, 73 and 80 psi) require a positive inlet pressure and these settings must only be used when boosting from the water mains. Fig. 11 Boosting from the mains 4.3.3 Self-learning setpoint If the pump cannot reach the user-defined pressure setpoint, the self-learning function will automatically lower the setpoint. See section 8.3.2 Self-learning function. 4.4 Shaft seal run-in The shaft seal faces are lubricated by the pumped liquid. A slight leakage from the shaft seal of up to 10 ml per day or 8 to 10 drops per hour may occur. When the pump is started up for the first time, or when the shaft seal has been replaced, a certain run-in period is required before the leakage is reduced to an acceptable level. The time required for this depends on the operating conditions, that is, every time the operating conditions change, a new run-in period will be started. Under normal conditions, the leaking liquid will evaporate. As a result, no leakage will be detected. The leakage is visible where the screws are mounted on the base plate. If the unlikely event of an internal leakage occurs, the liquid will be drained through the bottom of the pump. Install the pump in such a way that no undesirable collateral damage can arise. 5. Handling and storing the product 5.1 Handling the product 5.2 Storing the product If the pump is to be stored for a period of time, for example during the winter, drain it and store it indoors in a dry location. See section 10. Starting up the product after standstill. Temperature range during storing must be -40 to 70 °C (-40 to 158 °F). 6. Product introduction 6.1 Product description Fig. 12 Grundfos SCALA2 pump The inlet and outlet openings include flexible connections of ± 5 °. We recommend to use the default pressure of 3.0 bar (44 psi) which will suit most applications. The difference between the inlet pressure and outlet pressure must not exceed 3.5 bar (51 psi). Example: If the inlet pressure is 0.5 bar (7 psi), the maximum outlet pressure is 4 bar (58 psi). If you set the pressure too high, this might cause the pump to operate for up to three minutes after the tap is turned off.

Fig. 17 Expert menu overview 8.3.2 Self-learning function The factory setting for this function is "on". On If the pump cannot reach the user-defined pressure setpoint, the self-learning function will automatically adjust the setpoint. The pump will lower the setpoint to either 4.5, 3.5 or 2.5 bar (65, 51 or 36 psi). The self-learned setpoint is indicated on the operating panel by one flashing green light. After every 24 hours, the pump will automatically attempt to revert to the original user-defined setpoint. If this is not possible, the pump will again return to the self-learned setpoint. The pump will continue to operate with the self-learning setpoint, until the user-defined setpoint can be reached. Example: The user-defined pressure is set to 5 bar (72 psi), indicated by constant green lights on the pressure indicator panel. The pump is unable to reach this pressure due to negative pressure on the inlet side. The self-learning function automatically adjusts the setpoint to 3.5 bar (51 psi), indicated by one flashing green light on the pressure indicator panel. After 24 hours, the pump will automatically try to adjust the setpoint back to 5 bar (72 psi). Fig. 18 User-defined setpoint (left) and self-learned setpoint (right) How to reset the self-learned setpoint 1. You can manually reset the settings by pressing any button on the operating panel. The pump will immediately try to reach the original setpoint. 2. If the pump keeps reducing the setpoint due to self-learning, we recommend to reduce the setpoint manually on the operating panel. Off If you set the self-learning function to off and the pump is unable to reach the desired setpoint, the pump will show alarm 5. Expert settings are for installers only. Move cursor up.
