Küül® pads are a durable and long lasting cooling media.
Following are suggestions that will maximize the life and efficiency of the cooling pads.

• Port-A-Cool, LLC, recommends that the pH of the water be maintained at a level between 6 and 8. Exceeding these limits will seriously deplete the resin content of the pad and thus reduce its structural integrity.

• Remove and brush pads with a soft bristled brush and then flush system to remove debris. This should be done every 4 to 6 weeks during operating season.

• A clean water distribution system is the most important aspect for maintaining the entire evaporative cooling system.
This, coupled with quarterly inspection/maintenance checks, will ensure a properly operating evaporative cooling system.

• Frequently check system for damaged or clogged cooling pads.

• Minimize the number of on/off wetting cycles for the cooling pads.

• Completely dry the cooling pads once every 24 hours.

• Maintain a water bleed off rate of 3-5% per day.

• Ensure sump tank is enclosed and cleaned bi-weekly.

• Clean water filters weekly.
