Understanding the Water Management Systems in Seeley Evaporative Coolers


Evaporation Process: Water evaporates to cool the air, and some is discharged to maintain water quality. Seeing water discharge from your cooler every 1 to 3 hours can be normal. Here's why:

Water Management Overview: Your Seeley evaporative cooler will have either a WaterManager™ system or a continuous bleed system. Check with your dealer to find out which one is installed.

WaterManager™ System: The WaterManager™ system is economical and automatically maintains water quality. There are three types of WaterManager™ systems: Salinity Control, Timed Salinity Drain, and Continuous Bleed.

  1. Salinity Control (Economical and Drains Only When Necessary):
    • Automatic Monitoring: Continuously checks water quality and partially drains water when needed, replacing it with fresh water.
    • Frequency of Draining: Depends on water quality and evaporation rate. Hard water with higher mineral content results in more frequent draining. Soft water with low mineral quality means draining less often.
    • Salinity Control: Measures salinity levels and drains water when salinity and mineral content is high to maintain optimal water quality.
    • Drain Valve: Releases saline water, adding fresh water to dilute minerals and salts, ensuring efficient operation.
    • Operation Delay: If the tank is empty, the fan delays operation until the tank refills and the pads are saturated.
  2. Timed Salinity Drain (Every 1 or 2 Hours of Pump Run Time Depending on Model and Manufacture Date):
    • Timed Drain: Drains water at regular intervals (every 1 or 2 hours) regardless of water quality.
    • Frequency of Draining: Based on a timer set for continuous operation in cooling mode. The interval can be either 1 or 2 hours depending on the model and manufacture date.
    • Drain Valve: Releases water when the timer reaches the set point, adding fresh water to dilute minerals and salts.
    • Operation Delay: If the tank is empty, the fan delays operation until the tank refills and the pads are saturated.
  3. Continuous Bleed System (Over a Period Typically Discharges More Water than Salinity Control and Timed Drain):
    • Operation: Captures water as it runs off the pads and diverts some of it to the drain.
    • Adjustable Bleed Rate: The bleed rate is set by the installer based on local conditions. The more plugs that are inserted, the more water is diverted to the drain.
    • Maintenance: This system helps maintain optimal water quality and ensures the efficient operation of your evaporative cooler.
  4. Tank Drain Delay - Coolers with Water Management System (Salinity Control or Timed Salinity Drain):
    • The system will automatically drain the water from the tank 72 hours (3 days) after the last operation. This feature is designed to minimize water usage while ensuring proper system maintenance.

 

Why Water Discharge/Draining is Necessary:

  1. Keeping the Water Clean:
    • Minerals and Salts: When water evaporates, it leaves behind minerals and salts. If these build up, they can cause problems. Draining the water regularly helps to keep it clean.
  2. Enhancing Cooler Efficiency:
    • Improved Cooling: Clean water ensures the cooling pads can absorb and evaporate water effectively, which means your cooler can cool the air more efficiently.
    • Avoiding Scale: Scale is a hard, chalky buildup that can form on the pads and parts inside the cooler. Regular draining helps prevent this.
  3. Extending the Life of the Cooler:
    • Less Wear and Tear: By keeping minerals and salts from building up, you reduce the wear and tear on the cooler's parts.
    • Less Maintenance: Clean water means you won't have to clean or fix the cooler as often, saving time and money.

Importance of Sufficient Bleed-Off:

  1. Stopping Calcium and Mineral Buildup:
    • Inside Parts: Without enough bleed-off, calcium and minerals can build up on the parts inside the cooler, causing them to fail sooner and work less efficiently.
    • Cooling Pads: If the pads get clogged with minerals, they won't absorb and evaporate water as well, making the cooler less effective.
  2. Ensuring Consistent Performance:
    • Stable Cooling: Enough bleed-off ensures the cooler works consistently, providing steady and efficient cooling.
    • Less Breakdowns: By preventing mineral buildup and corrosion, you reduce the chances of the cooler breaking down unexpectedly.

By regularly draining the water and ensuring fresh water is introduced, you can keep your evaporative cooler running smoothly, efficiently, and for a longer time.

Water Usage Calculation: Seeley International cannot accurately calculate gas, water, or power consumption due to varying individual requirements and conditions. Factors include climatic conditions, installation specifications, product selection, service charges, and user expectations. Comparisons are based on equivalent-sized products under predetermined conditions.

Checking Water Manager Setting Using a MagIQtouch Controller: Navigate to: SETTINGS > COOLER > WATER MANAGER > 7378 > CONT.

  • Salinity Measurement: Replace water when the salinity level reaches the set point.
  • Timed Salinity Hours: Drains the tank every 1-2 hours.
  • No Drain Control: Salinity control is external to the electronics, e.g., continuous bleed.

 



The Tank Drain Delay (after the cooler is turned off) can be adjusted by the installer in the MagIQtouch menu to 3 hours, 12 hours, or 72 hours (3 days). Navigate to: SETTINGS > COOLER > TANK DRAIN DELAY > 7378 > 3hrs, 12hrs, 3 days > ACCEPT


Understanding Water Conditions for Your Evaporative Air Cooler

This guide is intended to provide awareness about water conditions and how they might affect your evaporative air cooler. Dealers and installers should be aware of their local conditions.

Water Hardness Levels:

  • Hard Water: Contains higher mineral content, primarily Calcium and Magnesium.
  • Soft Water: Contains low mineral content.

Water Hardness in Australia:

  • Soft: 0 - 60 ppm (mg/l)
  • Moderately Hard: 61 - 120 ppm (mg/l)
  • Hard: 121 - 180 ppm (mg/l)
  • Very Hard: >181 ppm (mg/l)

DIY Detergent Hardness Test:

  1. Fill a bottle with 50ml of water.
  2. Add drops of detergent and shake well after each drop until suds form.
    • Soft: <30 drops
    • Moderately Hard: ~40 drops
