Seasonal Shutdowns and Start-ups: A Comprehensive Guide for Optimal Aquatic Facility Performance
As the seasons change, so too do the operational demands on your aquatic facility. Whether you're preparing for a complete holiday shutdown or a period of reduced activity, and then gearing up for a bustling summer season, the processes of shutting down and starting up your hydraulic systems are critical. Done correctly, they prevent costly damage, ensure compliance, and guarantee optimal performance when it matters most.
That’s why we’ve put together this comprehensive guide to help you navigate these transitions smoothly, safeguarding your investment and extending the lifespan of your equipment.
1. The Shutdown Phase: Protecting Your Investmen
A well-executed shutdown is more than just turning off the power; it’s a proactive measure to protect your facility from the elements and potential issues during dormancy.
Water Chemistry and Filtration System Preparation:
Neutralise and Clean: Ensure all pool water is properly balanced and then drained. Thoroughly clean and backwash filters, removing any accumulated debris and bio-film. Consider a deep clean or chemical soak for filter media if recommended by the manufacturer or your maintenance schedule.
Chemical Lines & Dosing Systems: Flush all chemical lines with fresh water to prevent crystallisation or corrosion. Drain and clean chemical storage tanks and ensure dosing pumps are properly purged and stored according to manufacturer guidelines.
UV and Ozonation Systems: Power down and inspect UV lamps and ozone generators. Follow manufacturer instructions, which may include draining water from reactors or protecting sensitive components.
2. Hydraulic System Checks:
Drain All Pipework: This is paramount, especially in regions prone to freezing. Systematically drain all water from pumps, heaters, heat exchangers, chlorinators, and all associated pipework. Use air compressors where necessary to ensure lines are completely clear of water, paying special attention to low points and dead legs where water can accumulate.
Pump Care: Isolate power to all pumps. Disconnect and thoroughly clean pump baskets and impellers. For long-term shutdowns, consider removing drain plugs from pump casings and store smaller pumps in a dry, protected environment. Lubricate seals and bearings if recommended by the manufacturer.
Heater Protection: Drain all water from your heaters and heat exchangers. For gas heaters, ensure gas lines are shut off. For heat pumps, follow specific manufacturer guidelines, which often involves draining and possibly covering the unit.
Valves and Actuators: Ensure all valves are in a half-open position (if safe to do so) to prevent seals from sticking over extended periods. Lubricate moving parts where appropriate.
Flow Meters & Sensors: Carefully remove or protect any delicate flow meters, pressure gauges, or sensors that could be damaged by freezing or extended inactivity.
3. General Plant Room & Facility Security:
Cleanliness: Perform a thorough clean of the entire plant room. Remove any loose items, chemicals, or tools.
Pest Control: Implement measures to deter pests from nesting in warm equipment or pipework.
Security: Ensure all doors, windows, and access points to the plant room are securely locked. Consider regular checks during the shutdown period.
The Start-up Phase: A Smooth Revival
Bringing your facility back online requires careful planning and a systematic approach to prevent immediate issues and ensure long-term reliability.
1. System Reassembly & Inspection:
Visual Inspection: Before introducing water, perform a comprehensive visual inspection of all hydraulic components, pipework, valves, and electrical connections. Look for any signs of damage, corrosion, or leaks that may have occurred during the shutdown.
Filter & Pump Reassembly: Reinstall drain plugs, filter media, pump baskets, and any components removed for storage. Ensure all connections are secure.
Valve Positioning: Return all isolation and bypass valves to their correct operational positions. Double-check every valve.
2. Water Refill & Leak Checks:
Slow Fill: Gradually refill the pool and then the hydraulic system. This allows air to escape slowly and helps identify any immediate leaks.
Leak Detection: As the system fills, meticulously check all pumps, filters, heaters, valves, and pipe joints for any signs of water leaks. Address any leaks immediately before proceeding.
3. Initial System Operation & Performance Verification:
Pump Priming: Ensure all pumps are properly primed before starting. Air in the lines can damage pump seals and motors.
Gradual Start-up: Begin by starting pumps individually, checking pressure gauges and flow rates to ensure they are operating within expected parameters. Listen for unusual noises.
Heater & Sanitisation System Activation: Carefully bring heaters online, following manufacturer guidelines. Activate your sanitisation systems (chlorinators, UV, ozone) and verify their operation. Calibrate chemical controllers as needed.
Water Chemistry Balancing: Re-establish proper water chemistry balance, including pH, alkalinity, calcium hardness, and sanitiser levels. Allow the system to circulate for several hours, then retest and adjust.
Flow Rate & Pressure Checks: Verify that design flow rates and pressures are being achieved throughout the system. This indicates optimal circulation and filtration.
4. Comprehensive Operational Testing:
Full System Run: Once individual components are verified, run the entire system under normal operating conditions for an extended period (e.g., 24-48 hours).
Backwash & Clean: Perform an initial backwash and filter cleaning after a period of circulation to remove any residual debris from the system.
Final Safety & Compliance Checks: Ensure all safety systems are active and alarms are functional. Verify compliance with all local health and safety regulations before public access.
