How do I adjust my Grundfos pm2?
The PM 2 can be adapted to the individual installation. Via a number of DIP switches located behind the control panel, the start pressure can be adjusted from 1.5 to 5 bar. Furthermore, the PM 2 can be set to an operating mode with 1 bar differential pressure between start and stop of the pump.
How do you reset a Grundfos pressure pump?
The Auto-reset function can be activated/deactivated by press- ing the on/off button for 5 seconds. Note: When water is consumed, the pump will start and stop automatically, whether the Auto-reset light is on or off.
What happens if pressure tank pressure is low?
If tank pressure drops, the bladder may have a tear or hole in it. A tank is waterlogged if it is completely filled with water or has too much water to function correctly. Waterlogged bladder pressure tanks contribute to the following problems : The pump motor cycles – turns on and off – too often.
Why does my pressure switch Keep clicking on and off?
It is normal for the relay switch to “click” on and off slowly when you are running water continuously. It’s the pump switching on and off as pressure falls and rises.
How do I know if my Grundfos pump is working?
If you think you have a problem with your pump, try lightly touching it. If it’s working properly there will be a slight vibration and it will be warm to the touch. If your pump isn’t working, turn off its power supply and get a cloth and a screwdriver.
How much air should be in my water pressure tank?
Your well tank’s pressure should be set at 2 psi below the pressure switch’s cut-on point. This differs depending on your tank’s pressure settings. Most well tanks come set at 30/50. The cut-on pressure for the well pump is 30 psi, so the pressure of the tank should have a pressure of 28 psi.
How do I increase water pressure in my pressure tank?
The simplest way to increase your well water pressure is to adjust the pressure switch on your pressure tank. Pressure tanks have both “cut-on” and “cut-off” pressure settings. When the water pressure in your tank drops below the cut-on level, the pressure switch activates and increases the pressure in the tank.
