Hayward TriStar XL HCP3000 Series Variable Speed Pump - Owners Manual - Page 26

i. Re-check the strainer housing cover and all threaded connections for suction leaks. Check if all system hose clamps are tight. ii. Check voltage to ensure that the motor is rotating at full rpm's. iii. Open the housing cover and check for clogging or obstruction in suction. Check the impeller for debris. iv. Remove and replace the shaft seal only if it is leaking. • Low Flow - Generally: 1. Clogged or restricted strainer or suction line. Contact a qualified repair professional. 2. Undersized pool piping. Correct the piping size. 3. Plugged or restricted discharge line of filter, valve partially closed (high gauge reading). Sand filters - backwash as per manufacturer's instructions; D.E. filters - backwash as per manufacturer's instructions; Cartridge filters - clean or replace the cartridge. 4. Air leak in suction (bubbles issuing from return fittings). Re-tighten the suction and discharge connections using PTFE tape. Inspect other plumbing connections, and tighten as required. 5. Plugged, restricted, or damaged impeller. Replace the impeller including a new seal assembly. • Noisy Pump: 1. Air leak in suction piping, cavitations caused by restricted or undersized suction line or leak at any joint, low water level in pool, and unrestricted discharge return lines. Correct the suction condition or throttle return lines, if practical. Holding your hand over the return fitting will sometimes prove this, or by putting in a smaller eyeball fitting. 2. Vibration due to improper mounting, etc. Mount the pump on a level surface and secure the pump to the equipment pad. 3. Foreign matter in the pump housing. Loose stones/debris hitting the impeller could be the cause. Clean the pump housing. 4. Motor bearings noisy from normal wear, rust, overheating, or concentration of chemicals causing seal damage, which will allow chlorinated water to seep into bearings wiping out the grease causing bearing to whine. All seal leaks should be replaced at once. • Interference With Home Automation/Power Line Communication Equipment: 1. Make sure the terminal board connections agree with the wiring diagram on the pump data plate label. 2. Check for and correct any improper or loose wiring connections. 3. Install noise filter (from home automation/power line communication equipment vendor) to prevent equipment interference. Check System Messages Code Check System DC voltage too high Check System DC voltage too low Check System Drive is overheated Check System Drive overload Check System Pump has stalled Check System Pump failed to start Check System Motor phase lost Check System Processor failed Check System Communication failed Troubleshooting Indicates that the internal DC bus voltage is too high. Verify that line voltage is within 10% of pump rated voltage at the terminal block. Indicates that the internal DC bus voltage is too low. Verify that line voltage is within 10% of pump rated voltage at the terminal block. Also, verify that power supply connections are properly made at the circuit breaker as well as at the terminal block. Indicates that the internal components of the drive have become overheated. Motor airflow path should be checked for obstructions and cleared if present. Check ambient temperature and verify against motor nameplate (50°C/122°F). Indicates that motor current is too high. Check impeller, diffuser, shaft seal, and motor for any issues or binding. Indicates that the drive has lost control over motor shaft rotation. Check impeller, diffuser, shaft seal, and motor for any issues or binding. Indicates that the drive was not able to start the motor. Check impeller, diffuser, shaft seal, and motor for any issues or binding. Indicates that one of the motor phases is open and that the motor/drive may need to be replaced. Contact Hayward Technical Service for additional assistance. Indicates that there is a problem with the processor in the motor/drive, and that the motor/drive may need to be replaced. Contact Hayward Technical Service for additional assistance. Indicates that there are communication problems between the user interface and motor/drive. Connections between the user interface and motor/drive should be verified. 25 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
