Why is there insufficient chlorine in my Intex Water Filtration System?
- H
  howelltonyAug 5, 2025
  Several factors can cause insufficient chlorine in your Intex Water Filtration System. It could be due to not running the system long enough daily, or the salt level in the pool water might be too low (less than 2000ppm). Intense sunlight or an increased number of bathers can also reduce chlorine levels. Additionally, a clogged or dirty electrolytic cell or high UV level exposure may be the cause. To address this, try increasing the system's daily operating time, checking and adjusting the salt level, using a pool cover, cleaning the electrolytic cell, or covering the pool for 2 days with the device running and then test the water using the test strips.

  Joseph WilliamsAug 20, 2025
  If there is no LED display on your Intex Water Filtration System, first ensure that the system has power by checking the switch. Also, reset the household socket GFCI. If these steps don't work, it's possible a power fuse has blown or there is an LED failure. In these cases, contact the Intex Service Center.

What to do if there are white flakes in the water of my Intex Water Filtration Systems?
- D
  Daniel FieldsAug 28, 2025
  If you notice white flakes in the water of your Intex Water Filtration System, it's likely due to excessive calcium hardness. To fix this, drain about 20-25% of the pool water and add fresh water to lower the calcium hardness. Also, inspect the electrolytic cell for scale buildup and clean it if needed.

What to do if the LED panel code flashes and the alarm is on for my Intex Water Filtration Systems?
- E
  Elizabeth DominguezNov 11, 2025
  If the LED panel code is flashing and the alarm is on for your Intex Water Filtration System, several issues could be the cause. Here are a few things to check: * Make sure the filter pump is attached and working correctly. * Ensure that the circulation line isn't blocked by removing the black hat-like plugs, cleaning the filter cartridge, and releasing any trapped air. * Verify the inlet and outlet hoses are connected in the correct direction. * Clean the titanium electrode to remove any scale on the flow sensor pins. * Check that the electrode cord is securely plugged in. * Reset the timers on both the filter pump and saltwater system to resolve any conflicts. * Inspect the electrolytic cell for dirt or scale and clean if necessary. * Add salt if the salt level is low or...

This document describes the Intex Saltwater System, Model CS3110, a device designed for maintaining pool water sanitation.

Function Description:

The Intex Saltwater System is an electrolytic cell that uses sodium chloride (salt) added to the pool water to generate chlorine. This process helps keep the pool water clear and clean by sanitizing it without the need for traditional chlorine tablets or liquid chlorine. The system requires a separate filter pump to circulate the water and ensure proper functioning. It is designed to be installed as the last piece of pool equipment in the water return line to the pool, a placement that extends the life of the titanium plates within the electrolytic cell. The system includes a self-cleaning function for the titanium electrode, which helps maintain optimal efficiency.

Important Technical Specifications:

Model: CS3110
Power: 110-120 Volt AC
Amperage: 0.5 A
Wattage: 30 W
Ideal Salt Level: 3000 ppm (parts per million)
Maximum Chlorine Output/hour: 4 grams/hour
Filter pump minimum flow rate: 300 gallons/hour (1136 liters/hour)
Filter pump maximum flow rate: 1000 gallons/hour (3785 liters/hour)
Hose Connection Fittings: 1-1/4" (32mm)
Salt Type: Only Sodium Chloride (NaCl) salt that is at least 99.8% pure, or water conditioning salt pellets (compressed forms of evaporated salt). Iodized or yellow (yellow prussiate of soda) colored salt should not be used.
Optimum Salt Levels: Between 2500-3500 ppm, with 3000 ppm being optimal.
Cyanuric Acid Recommendation: Approximately 0.35% of the salt level (e.g., 0.35 Lbs for 100 Lbs of salt) to reduce chlorine loss due to UV rays.

Usage Features:

Setup: The system is designed for above-ground pools (AGP) and must be connected in line after the filter pump. Installation involves connecting the system to the filter pump outlet and the pool return line using connector hoses and clamps.
Operation:
- Start-up: Plug in the power cord, test the GFCI, and press the power button. The LED display will show "00" flashing, indicating it's ready for programming.
- Setting Operating Hours: Use the timer button to set the desired operating hours (1 to 12 hours) based on the pool size and ambient temperature, as indicated in the "Operating Time Table." The system will then activate daily at the same time for the set duration. The filter pump must operate for 5 minutes before and 15 minutes after the saltwater system's operation.
- Keypad Lock: Press the lock button to secure the programmed settings. The "WORKING" indicator will light up, and the LED will show remaining chlorinator hours. If forgotten, the system locks automatically after 10 seconds.
- Stand-by/Power Saving Mode: After a cycle, the "SLEEP" indicator lights up, and the LED flashes "93." The system then enters a power-saving mode, with the LED display going blank after 5 minutes. It automatically restarts its daily cycle after 24 hours.
- BOOST Mode: This mode allows for increased chlorine production for 36, 48, or 60 hours to address dirty or grimy pool water. The "BOOST" indicator lights up when active.
- Self-Clean Cycle: The default self-clean cycle for the electrode is 14 hours. This can be adjusted to 10 or 6 hours based on the pool's calcium hardness level (0-150 ppm for 14 hours, 150-250 ppm for 10 hours, 250-350 ppm for 6 hours). This feature reverses the polarity of the electrode to prevent scale buildup.
Salt Management:
- Adding Salt: Turn on the filter pump, keep the Saltwater System off, determine the amount of salt needed using the "Salt Table," spread salt evenly around the pool perimeter (avoiding the skimmer), brush the pool bottom, and run the filter pump for 24 hours to dissolve. After dissolution, turn on the Saltwater System and set the operating time.
- Removing Salt: If the salt level is too high (Code 92 alarm), partially drain the pool (approx. 20%) and refill with fresh water until the alarm disappears.
Cyanuric Acid: Add cyanuric acid to reduce chlorine loss from UV rays, especially after the pool water is clear and clean. Refer to the "Cyanuric Acid Table" for dosage.

Maintenance Features:

Titanium Electrode Cleaning: The titanium electrode has a self-cleaning function, but manual cleaning may be required monthly, especially in hard water areas.
- Procedure: Unplug the unit, insert hat-like plugs into strainer openings to prevent water spillage, disconnect hoses, unscrew the electrode plug collar, disconnect the plug, unscrew the cell nut, remove the electrode, soak it in kitchen-grade vinegar for 1 hour, and then flush with a high-pressure garden hose. Reassemble in reverse order.
Water Chemistry Testing: Use Intex Test Strips (included with the product) to test "Free Chlorine," "pH," "Calcium Hardness," and "Total Alkalinity" levels weekly. Maintain chlorine concentration at 1.0-3.0 ppm.
Long Term Storage: Disconnect the power cord, disconnect the system from hoses, air-dry the unit, inspect and clean the electrolytic cell, and store in a dry place between 32°F (0°C) and 97°F (36°C). The original packaging can be used for storage.
Troubleshooting: The manual provides an LED Code Chart and a Troubleshooting Guide to help diagnose and resolve common issues such as insufficient chlorine, white flakes in the water, no LED display, low pump flow, low/high salt levels, and electrode problems.
Warranty: The Krystal Clear Saltwater System comes with a 2-year limited warranty, the titanium electrode with a 1-year warranty, and hoses & fittings with a 180-day warranty. Proof of purchase is required for warranty claims.
