Check that the voltage and frequency of the product match voltage and frequency of the installation site. I am at my wits end with two this and am trying to fix this issue. Receiving the product 2.1 Inspecting the product Check that the product received is in accordance with the order. ![]() My goal is to end up with good water pressure and a quiet unit that does not fail after 4 years!! I am at my wits end with two this and am trying to fix this issue. I am now concerned that the failure of the previous pumps (well and MQ) were caused by the same thing that is causing the issue with the SCALA2. The pump will be in a closet in the same room that we are finishing. we plan to finish the basement and don’t want to go back to the MQ as it was loud - and this judgement is based off noise heard on the main and second level. The unit is Quiet!! However we are concerned that the motor fluctuations in the pump and our water heater will cause the units to fail prematurely. we like the SCALA 2 - pressure is good and immediate. I was told that the town mandated the builder place pressure pumps in all the houses on our street in order to get approval to build the development. ![]() We have an irrigation system that we run at most 6-8 weeks in the summer. Now the Gurunfos rep is saying that we should get rid of the SCALA 2 and go back to the pump we had previously- MQ-3.Ĩ yrs ago we had a well pump which failed after 4ish - we were told there was a hole in the bladder. per Grundfos reps - back flow valves removed from the unit and there was one additional valve before the unit that was also removed. water pressure checked at the house (after the meter) -35psi water pressure checked at the street - 35psi we noticed and then reported the issue to our plumber, Grundfos instructed him to replace the pump to fix the issue. I have video clips of the pump and water heater along with a pressure gauge readings while it is happening. The fluctuations also cause fluctuations at our on demand water heater - the temp of the water doesn’t change but you can hear the heater motor surge when the SCALA surges. Enter the product for which you want to troubleshoot in the search bar at the top. You can see and hear the water fluctuations at the end source (toilet and faucets). Whichever situation you’re in, you can find the pump troubleshooting guide you’re looking for in 3 possible places: Grundfos Product Center the Grundfos for Engineers Search Engine and the Grundfos GO Remote app. Periodically the #5 error code lights up. This cycle repeats about every 45-6o seconds as long as the demand remains. However, with a large draw (toilet flush, dish and clothes washer and tub) the pressure starts off good and then after about 45 seconds the pressure fluctuates from low to high. ![]() Pump turns on with demand and has good pressure. Check the non-return valves, and keep the ventilation holes free of dust.We had a SCALA 2 installed several months ago and have been caving issues ever since. SCALA1 requires no maintenance, but it is recommended to keep the pump clean. It is also possible to add external input control and schedule a pump operation via calendar function. With Grundfos GO, you can easily setup SCALA1 as a Twin booster system, operating as duty/stand by as well as duty/assist. The pump has a built-in motor protection that will stop the pump if exposed to excessive temperature due to high ambient temperature, in case of seizure or overload, thus preventing a motor burnout. Max runtime protection can stop the pump after a desired period of continuous operation, preventing potential damage due flooding in case of pipe breakages.Cycling protection which will prevent pump starting frequently in case of minor leakages in installation.Dry running protection that will automatically stop the pump in case of water shortage.SCALA1 incorporates advanced protection features such as: SCALA1 can communicate with Grundfos GO app via built in Bluetooth, which enables detailed pump monitoring and high customization options, making this pump a good fit for every application. This facilitates easy installation and start-up of the pump and provides more reliable water supply in installations where there is a risk of dry running and leakages in suction hose or pipes. Provided it is filled with water, the pump can lift water from a depth of 26 feet in less than 5 minutes. As it is self-priming, the SCALA1 can pump water from a level below the pump. De Grundfos SCALA 2 is een volledig geïntegreerde, zelfaanzuigende, compacte watervoorziening voor drukverhoging binnen huishoudelijke toepassingen.
