Do not overfill the unit. If the lower (supply) tank is 1/2 full, do not fill the upper (fill) water tank more
than halfway. Overfilling the tank may cause the unit to overflow.
IMPORTANT: The white polymer connector for the wire to the tap assembly is designed to fit in one
direction only. If this is disconnected and resistance is felt when reattaching, do not attempt to force it
into place. Reverse its position to reconnect.
Keep the PiMag
Waterfall
Component replacement
Hand wash the water tanks periodically (approximately once a month) to keep them clean and free of
deposits. You may use a mild detergent or soap. When cleaning the unit, do not use a scrubber or
paper towels, which may result in scratches on the surface. Use a soft cloth to dry.
The prefilter may be rinsed or flushed if it becomes discolored or water flow is reduced. Use cold water only.
Do not boil the filter cartridge. Clean only by rinsing in cold water.
The replacement filter must be prepared by soaking (preferably for 8 hours) before installation.
Follow steps 3 through 5 as described in the Assembly Instructions in this manual.
After changing the filter (and prefilter pads), reassemble the Waterfall. Fill the unit with cold water. Then
press and hold the LED indicator button for 8 to 10 seconds, to reset the indicator for a new cycle. The

two full cycles.
