Limitations & Safety Notes

• Not suitable for Bonaire evaporative cooler models other than those specified (DS01, DS11, DS21, DS31).

Tradie Pro Tip

When you're swapping out these pads, take an extra 10 minutes to give the water tray and pump a good clean. It prevents algae and scale build-up, which means less call-backs and better cooling performance for the customer.
