What 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.
Why is my DAB Water Pump not providing the required water pressure?
If your DAB Water Pump isn't delivering the expected performance, consider these possible reasons: * The set might be undersized for your system's needs; consult the Technical Catalogue to verify. * Water consumption could be exceeding the well's flow rate or the capacity of the first collection tank. Increase the flow rate from the well or tank. * The motors might be turning in the wrong direction. Correct this as described in point 5.5 of the “Starting up” section. * One or more pumps could be clogged. Dismantle and clean the pump body and impellers, ensuring they are in good condition. * Pipes might be obstructed. Clean or replace them. * The foot valve could be clogged or blocked (if the set is above head). Clean or replace it. * Water might be recycling between the pump...
What to do if my DAB Water Pump set does not start?
If your DAB Water Pump set fails to start, there are several potential causes to investigate: 1. Ensure that the main motive power switch and/or main auxiliary circuit switch are turned on (position “1”). Check for the green light indicating that the panel is live. 2. Check the transformer and fuses for any issues causing a lack of voltage at the auxiliaries. 3. For sets with three pumps, a faulty automatic inverter SZ3 could be the problem. You can connect together the input and output connectors XC1 and XC2 of the inverting device and order a new automatic inverter. 4. Verify that electric power is reaching the pump remote control switches by checking the operation of the remote control, minimum pressure switch, and minimum level float, which are placed in series. 5. Inspect the el...
Why does my DAB 2 JET SET stop and not restart?
If a pump in your DAB Water Pump set stops and refuses to restart, here’s what to investigate: * For single-phase pumps, the internal motor protection might have tripped. For both single-phase and three-phase pumps, the motor protection might have tripped. Allow the motor to cool down. Refer to the E-BOX Electric Panel instructions booklet. * Excessive energy consumption could be the issue. This might occur if the pump is under excessive force due to dirt, a missing phase, dry operation, or worn bearings. Identify and eliminate the cause. * Check if current is reaching the coil of the remote control switch using a tester to examine the electric circuit up to the coil, and repair any interruptions. * The remote control switch coil itself might be interrupted, requiring replacement....
