There may be no power when turning on the CircuPool RJ Classic Series due to the following reasons:

1. The system is in "Power Off" mode. Press the Power button on the keypad to activate it.
2. The power protection mechanism has activated, possibly due to a power surge, lightning strike, or heavy storm.
3. A blown fuse may be present (look for a black or grey mark in the fuse).
4. Excessive calcium deposits or debris may be contacting the titanium cell.
5. The reset breaker may be faulty and need replacement.

If you press the super chlorinate button the power off lights up but if you press the power button nothing happens.

If the power button on a CircuPool RJ Classic Series unit does not respond while the super chlorinate button activates the power off light, it likely indicates that the unit is in "Power Off" mode. In this case, press the Power button at the top of the keypad to activate the system. If this does not work and no LED lights or display appear, despite confirmed input power, the power protection mechanism may have activated due to a power surge, lightning strike, or debris on the cell. A qualified professional should perform further troubleshooting.

  • Page 2: Basic Water Chemistry

    CircuPool Help Guides: RJ Classic Series BASIC WATER CHEMISTRY Managing the water chemistry of your pool is critical for effective chlorination and ensuring the safety of swimmers in the pool and preventing damage to your pool materials and equipment. This guide reflects national standards for pool water chemistry; for in-depth assistance, please consult your local pool professional and provide them with a copy of your manual in order to ensure that they are familiar with your specific pool equipment.
  • Page 3 CircuPool Help Guides: RJ Classic Series pH - Acidity/Alkalinity pH indicates how acidic or basic the water is. pH should be tested daily at first. Once you gain experience with your pool, less frequent monitoring may be appropriate, depending on your pool's typical rate of pH change. pH levels between 7.5 and 7.8 are ideal, while levels between 7.2 and 7.8 are acceptable for swimming.
  • Page 4: Phosphates & Nitrates

    CircuPool Help Guides: RJ Classic Series BASIC WATER CHEMISTRY - PHOSPHATES & NITRATES Phosphates are a part of the environment: Phosphates became a household word in the 1970's. This is when people started to use low-phosphate and phosphate-free laundry detergents to help minimize the detrimental effects of excess phosphates in lakes, streams, wetlands and other runoff areas- effects such as unwanted algae blooms.
  • Page 5: Langelier Saturation Index

    CircuPool Help Guides: RJ Classic Series BASIC WATER CHEMISTRY - LANGELIER SATURATION INDEX (LSI) LSI is a measurement of the water’s ability to absorb and hold solids in a solution. It is important to know that the scale on which LSI is measured is very narrow, meaning that a small change can indicate a significant difference in your pool.

    CircuPool Help Guides: RJ Classic Series Water Fault / Add Salt LED Indicators This Help Guide will troubleshoot possible causes for the “Water Fault” and/or “Add Salt” light to remain continuously illuminated. IMPORTANT: The "Add Salt" light is only a display indicator and does not cause the system to change its behavior or cease operation if the salt level is above the minimum level required.
  • Page 13 CircuPool Help Guides: RJ Classic Series 2. Low or Absent Water Flow through the Salt Cell The water flow should always fully fill the entire Electrolytic Cell at all times. The minimum flow requirement is typically 30 gallons per minute. As the Electrolytic Cell has no ability to increase or decrease water flow, if the water is not completely filling the Cell then that indicates a problem with the pool's circulation system.

    CircuPool Help Guides: RJ Classic Series How to Clean the Electrolytic Cell The Electrolytic Cell has the self-cleaning Reverse Polarity feature built-in, which prevents mineral deposits from forming rapidly. However, the Cell may eventually need to be manually cleaned. The frequency of mineral build-up is dependent upon the balance of the pool's water chemistry, specifically the Saturation Index (see page 5).
