To Next PageTo Next PageWhat to do if my DAB 2 JET SET Water Pump set won't stop running?
If your DAB Water Pump set continues to run, not shutting off, there are a couple of things you should check: * Inspect the system for significant water leaks in joins, couplings, and pipes. * Examine the pressure switches or pressure transmitter for faults or clogs. Clean or replace them as needed.
Why does my DAB 2 JET SET cycle on and off too often?
If the pumps in your DAB Water Pump set are starting and stopping too frequently during operation, here are a couple of potential reasons: * The expansion vessels might be damaged. Empty them and check the preloading (refer to the “Instructions for running the set” section). If the diaphragm has a hole, replace it. * The starting and stopping pressure calibrations might be too close. Adjust the settings (refer to the “Regulating the set” section).
Why is the motor of my DAB Water Pump vibrating?
If the motor of a pump in your DAB Water Pump set is vibrating, consider these possible causes: * The contacts on the remote control switch might be worn or faulty. Replace the remote control switch. * The pump might be blocked. Free it. * The bearings might be worn. Replace them. * If it’s a three-phase motor, a phase might be missing. Check the motor power supply.
How to prevent water hammer in my DAB Water Pump system?
To address water hammer in your DAB Water Pump system: * If water hammer occurs during operation, check the non-return valve of the hot water distribution mains. * If water hammer occurs when turning off the flow, install more expansion vessels or water hammer dampers in the affected pipe.
Why is my DAB Water Pump running backwards when stopped?
If one or more pumps in your DAB Water Pump set are turning in the opposite direction when stopped, here’s what to check: * The respective non-return or foot valves may not be closing properly or are blocked. Check their seal and correct operation. * The respective suction pipe might not be hermetically sealed. Test the seal under pressure.
