Receiving the product 3.1 Inspecting the product On receipt of the product, do the following: 1. Check that the product is as ordered.
TM075004 B C English (GB) A Base plate [mm (in)] 135 (5.3) B 163 (6.4) C 1 2 3 174 (6.9) 5.2 Connecting the pipe system Make sure that the pump is not stressed by the pipe system. Always loosen and tighten the union nuts on the inlet and outlet ports by hand. Damage to the inlet and outlet parts increases the risk of leakage. We recommend that you install isolating valves on the inlet and outlet side of the pump. 1. Turn the union nuts by hand to loosen the inlet and outlet ports.
English (GB) TM075387 Correct pipe sizing for connection to the pump inlet or outlet 5.2.2 Maximum tapping point We recommend that you install the unit so that the height between the unit and the highest tapping point does not exceed the values shown in the table below. TM075383 H Maximum tapping point Model Maximum height [m] 3-25 10 3-35 15 3-45 20 5-25 10 5-55 25 In case the highest tapping point is higher than the values in this table, the external input may be used.
5.3.2 Suction from a tank We recommend that you follow the installation examples. Valves are not supplied with the pump. 5.3.1 Suction from a well 1 2 2 3 3 1 4 5 A 5 7 4 6 Pos.

5.3.4 Inlet pipe length The overview below shows the different possible inlet pipe lengths, depending on the vertical pipe length. The overview is only intended as a guide. In some countries, boosting from the city water mains is prohibited. Please follow local regulations regarding this application. L 1 2 3 9 4 H 7 10 6 2 8 3 TM075262 5 Pos.
WARNING Electric shock Death or serious personal injury ‐ The protective earth (PE) of the power outlet must be connected to the protective earth of the pump. The plug must have the same PE connection system as the power outlet. ‐ 4. Tighten the terminal screws and the cable clamp screw. Make sure not to overtighten the cable clamp screw. 1 2 3 4 Example, plug wiring All electrical connections must be carried out by qualified persons in accordance with local regulations.
8. Control functions 3. Open the tapping point that is the highest or furthest away from the pump to let out air trapped in the system. 8.1 Operating panel English (GB) 2. Open all isolating valves. 4. Turn on the pump's power supply. All the symbols on the operating panel will light up briefly. The Stop icon remains on. 5. Press the Start/Stop button to start the pump.
English (GB) 8.2 Auto reset This function allows the pump to automatically check if the operating conditions are back to normal. If the operating conditions are back to normal, the alarm indication will be reset automatically. The factory setting is: ON The auto reset function works as follows: Alarm Auto reset action Configurable Default Dry run The pump will attempt eight restarts at five-minute intervals. If not successful, this cycle will be repeated after 24 hours.
2 This pump allows connecting external input as an additional condition to the pump operation. External input may be beneficial in the following situations: level switch in roof tank filling to stop the pump when the tank is full • inlet pressure switch to stop the pump in case of raised inlet pressure • moisture detection switch in irrigation applications to run the pump only when the ground is dry.
In the installation below, the level switch is used to signal the pump to run when the water level in the tank drops. The example below shows the float switch in the input closed position. In this case, the pump should not run, and Grundfos GO Remote settings indicate that the input is closed. If you exceed the maximum tapping point of the pump, the external input should run on input only.
9.3 Resetting to factory settings If the performance mode needs to be changed from the default setting, follow these steps: To reset the pump to factory settings via the HMI: English (GB) 9.2.3.1 Selecting the performance mode 1. Press and hold [Enable/Disable] and [Reset] buttons simultaneously for 5 seconds. 1. Remove the pump cover. a. Unscrew and remove the priming plug from the pump. b. Loosen and remove the inlet and outlet connections from the pump. Enable/Disable button c.
COMMUNICATION CABLE INPUT TM075388 Running in Duty/Assist operation mode brings more flow on the outlet side, as both pumps can run at the same time. A pump with an assigned priority will start first and, in case it cannot deliver the necessary flow, the second pump will start. In case one pump fails to start, the system will continue running with one pump. The pumps will switch priority at the start based on the alternation settings. Alternation can be set based on runtime or number of starts.
English (GB) Range and default values for alternation Minimum Default Maximum Resolutio n Alternation of starts and stops 1 1 100 1 Alternation runtime [h] 0.5 5 100 0.5 WARNING Electric shock Death or serious personal injury ‐ Switch off the power supply before you start any work on the product. Make sure that the power supply cannot be switched on accidentally. WARNING Chemical hazard Death or serious personal injury ‐ Make sure that the product has only been used for water.
English (GB) WARNING Electric shock Death or serious personal injury ‐ Check that the product is intact and not cracked. Especially if the product was not drained before standstill or was exposed to frost. TM075258 CAUTION Impurities in the water Minor or moderate personal injury ‐ Before the pump is used for supplying drinking water, flush the pump thoroughly with clean water.
If the product is to be stored for a certain period of time, for example, during winter, drain it by removing the drain plug and store the product indoors in a dry location. Temperature range during storing must be from -40 to 70 °C (-40 to 158 °F). Maximum relative humidity during storage: 95 % RH. A 15. Fault finding CAUTION Hot surface Minor or moderate personal injury ‐ Do not run the pump continuously with a closed inlet or outlet valve.
English (GB) 15.2 The pump does not start Grundfos Eye Indicator light Automatic reset Cause Remedy - - The fuses in the electrical installation have blown. Replace the fuses. If the new fuses blow as well, check the electrical installation. - - The earth leakage circuit breaker or the voltage-operated circuit breaker has been tripped. Cut in the circuit breaker. - - No power supply. Contact the power supply authorities.
15.4 The pump is running Remedy Grundfos Eye Indicator light Cause Automatic reset English (GB) Cause Cause Remedy No The non-return valve is not properly closed, or the pipe system is leaking. This happens when cycling alarm and/or leakage alarm are disabled. Check and repair the pipe system, or clean, repair or replace the non-return valve. No Small continuous consumption. Check the taps and reconsider the usage pattern (ice machines, water evaporators for air-conditioning, etc.). 15.
English (GB) Cause 15.7 The pump starts and stops too frequently Remedy Grundfos Eye Indicator light Automatic reset Cause Remedy - - Leakage in suction pipe or air in the water. Restore the water supply or repair suction pipe. - - A tap has not been closed entirely after use. Check that all taps have been closed. See section Anti-cycling. - - Minor leakage in the system. Check the system for leakages. See section Anti-cycling. Cause 15.
English (GB) If the fault disappears by itself, the pump will attempt to reset automatically, and the fault indication will disappear. The fault indication will still be visible in the Grundfos GO Remote alarm log.
