Pool Maintenance Summary

The Hayward SwimPure Plus is an automatic chlorine generation system designed for pool and spa sanitation. It operates by converting a low concentration of salt (sodium chloride) in the pool water into free chlorine, which then sanitizes the water by killing bacteria and algae. After sanitizing, the chlorine reverts back to sodium chloride, allowing for continuous recycling and reducing the need for additional sanitizing chemicals. Salt only needs to be replenished when water is lost due to backwashing, draining, or splashing.

Function Description:

The SwimPure Plus is suitable for most residential swimming pools up to 40,000 gallons (150,000 liters) and commercial pools up to 25,000 gallons (95,000 liters). The actual chlorination required varies based on bather load, rainfall, temperature, and pool cleanliness. Hayward does not recommend using this system to generate bromine.

The system uses one of three chlorinator cells, which must be purchased separately:

T-CELL-15: For pools up to 40,000 gallons
T-CELL-9: For pools up to 25,000 gallons
T-CELL-3: For pools up to 15,000 gallons

Important Technical Specifications:

Salt Levels: Ideal range is 2700 to 3400 ppm (parts per million), with 3200 ppm being optimal. Low salt levels reduce efficiency, while high levels can cause the system to shut down and may make the water taste salty (typically above 3500-4000 ppm).
Water Chemistry (Ideal Levels):
- Free Chlorine: 1.0 to 3.0 ppm
- pH: 7.2 to 7.8
- Cyanuric Acid (Stabilizer): 60 to 80 ppm (80 ppm best)
- Total Alkalinity: 80 to 120 ppm
- Calcium Hardness: 200 to 400 ppm
- Metals: 0 ppm
- Saturation Index: -0.2 to 0.2 (0 best)
Power Input: 120VAC or 240VAC. The unit is shipped configured for 240VAC; jumpers must be moved for 120VAC operation.
Circuit Protection: Protected by a 20 amp mini ATO fuse on the circuit board.
Mounting: Raintight enclosure suitable for outdoor mounting, minimum 5 ft (2 meters) horizontal distance from the pool/spa. Mount vertically with knockouts facing downward. Do not block the four sides of the control as it acts as a heat sink.
Plumbing: Flow switch and cell should be plumbed in the return line, preferably downstream of all other pool equipment (filter, heater, solar). Designed for 2" (51mm) PVC pipe; adapters for 1½" (38mm) plumbing are not included.
Flow Switch: Requires at least a 12" (25cm) straight pipe run before (upstream) the flow switch. The arrow on the flow switch (top of gray hex) must point in the direction of water flow.
Electrolytic Cell: Install using provided unions, hand-tightened for a watertight seal.
Bonding: Must be bonded with an 8 AWG copper wire (6 AWG Canada) to the pool bonding system.

Usage Features:

Main Switch (AUTO/SUPER CHLORINATE/OFF):
- AUTO: Normal operation, chlorine production based on "Desired Output %" setting during filtering/pumping cycle.
- SUPER CHLORINATE: Electronically "super chlorinates" (shocks) the water for 24 hours (pump must be on). Useful for high bather load, heavy rain, or cloudy water.
- OFF: Prevents electrolytic cell energization and chlorine generation. Use for servicing equipment.
"Desired Output %" Adjustment Knob: Controls the amount of chlorine generated. Raise to increase, lower to decrease chlorine levels. Inactive when controlled by a remote pool automation system.
Indicator LEDs:
- POWER: Indicates input power.
- GENERATING: Steady during normal operation; flashing indicates water is too hot or cold to operate.
- SUPER CHLORINATE: Illuminates during super-chlorination.
- REMOTELY CONTROLLED: Illuminates when a remote pool automation control (Hayward Pro Logic, Pentair Intellitouch, Polaris Eos) is controlling the unit. Flashing indicates the automation control is in SERVICE or TIME-OUT mode.
- NO FLOW: Illuminates when flow switch detects no water flow, stopping chlorine generation. Flashing indicates a 15-60 second time delay.
- CHECK SALT: Flashing indicates low salt (below 2700 ppm) and low efficiency; steady indicates very low salt and system shutdown.
- HIGH SALT: Illuminates when salt level is too high, causing system shutdown.
- INSPECT CELL: Flashing indicates reduced cell efficiency or scheduled inspection; steady indicates greatly reduced efficiency and system shutdown.
Diagnostic Displays: Sequential pushes of the "diagnostic" button cycle through: Pool temperature, Cell voltage, Cell current, Desired Output %, Instant salinity, Product name, Software revision level, and Chlorinator cell type.
Temperature Display: Shows current pool water temperature in °F (default) or °C.
Salt Display: Shows average salt level in ppm (default) or grams per liter.
Instant Salinity: Shows real-time salt level. Can be used to "update" the main Salt Display after adding salt.
Chlorinator Cell Type Setting: Must be configured for the specific cell installed (t-3, t-5, t-9, t-15).
Low Temperature Cutoff: Automatically stops generating chlorine when water temperature drops below 50°F (can be overridden with SUPER CHLORINATE).
Pool Automation Control Integration: Compatible with Hayward Pro Logic, Pentair Intellitouch, and Polaris Eos. When connected, the automation control manages functions, and the SwimPure Plus's main switch and "Desired Output %" dial are disabled.

Maintenance Features:

Electrolytic Cell Self-Cleaning: The cell has a self-cleaning feature to maintain optimum efficiency.
Cell Inspection Reminder: The "Inspect Cell" LED flashes after approximately 500 hours of operation to remind users to inspect and clean the cell. Pressing the diagnostic button for 3 seconds resets the timer.
Cell Cleaning:
- Turn off power before removing.
- Inspect for scale (crusty/flaky deposits) or debris.
- Flush with a high-pressure garden hose.
- If deposits remain, use a plastic or wood tool to scrape them off (do not use metal).
- For severe cases, use mild acid washing: Mix a 4:1 solution of water to muriatic acid (ALWAYS ADD ACID TO WATER). Soak the cell for a few minutes (ensure wire harness compartment is not submerged), then rinse. Repeat if necessary.
Winterizing: Drain all water from the pump, filter, and supply/return lines in areas prone to freezing temperatures to prevent damage to the electrolytic cell and flow switch. The electronic control can withstand winter weather and does not need to be removed.
Spring Start-up: Do not turn on the SwimPure Plus until pool water chemistry is balanced to recommended levels.
Salt Type: Use only sodium chloride (NaCl) salt that is >99% pure, such as food quality or water softener salt (e.g., "Coarse Solar Salt"). Do not use rock salt, salt with yellow prussiate of soda, anti-caking additives, or iodized salt.
Adding Salt: For new plaster pools, wait 10-14 days. Turn on circulating pump, add salt directly to the pool, brush to speed dissolving, and run filter pump for 24 hours for even dispersion.
Removing Salt: Only by partially draining the pool and refilling with fresh water.
Cyanuric Acid (Stabilizer) Check: Always check stabilizer levels when checking salt, as they often decline together.
