Easy, one-step cleaner for evaporative coolers and water lines that have salt, calcium, rust or other mineral buildup. Similar to JR’s ECT, with higher amounts of organic and inorganic acids to remove buildup quickly. JR’s will protect the metal surfaces of the cooler to prepare the cooler and pads for better, more efficient performance. For increased performance/maintenance, add JR’s ECT when refilling reservoir to create a cooler environment with cleaner air and to conserve water usage. This product contains organically-inhibited acids. Use 32 oz max in a full reservoir of fresh water.

Pad replacement
Conserves water: one quart of concentrate is used per 25 gallons of water in reservoir

INSTRUCTIONS

If your cooler is equipped with a bleed-off, disconnect it. Remove all loose material from pads and reservoir. Rinse out the pan area. Fill reservoir with clean water and add contents of JR's ONCE THROUGH bottle.

IMPORTANT
Remove blower drive-belt, replace pad panels and circulate water for 6 to 12 hours. If build up is excessive, additional treatments of JR's ONCE THROUGH CLEANER may be required. When cleaning is finished, attach hose to drain and flush reservoir. Do not allow water flushed out of reservoir to settle on roof, side walks, driveways or plants. Then simply reinstall drive-belt, and refill reservoir with clean fresh water. For better cooler performance and proper maintenance add JR's EVAPORATIVE COOLER TREATMENT when refilling reservoir. It will cause your home to become cooler, and your air much cleaner, as well as save you on the use of water.
