This chiller can be used simply by connecting your garden hose to both ends of the chiller. You can either slip the garden hose onto the ends of the chiller directly then secure with stepless hose clamp. Alternatively for a better connetion use the compression fittings.
Then lower the chiller into your hot wort and cycle the water through the chiller until you reach the desired temperature.
While the water is flowing through the chiller if you agitate your hot wort this will significantly aid the heat transfer from the wort to the chiller coil and will reduce the cooling time by more than half.
