NICREW Automatic Gravel Cleaner Instruction Manual

NICREW Automatic Gravel Cleaner

Introduction

With its intelligent 2-in-1 design, the Automatic Gravel Cleaner doubles as both a gravel cleaner and water change system for quick and easy cleaning with no siphoning or annoying mess to clean up. The suction power of the cleaner is designed to remove dirt particles without too much disturbance to the gravel. A mesh filter compartment collects the dirt while letting the water flow back into the aquarium. The filter compartment is simple to remove.

2 1 Cleaner

Gravel Cleaner

This cleaner has sealed the electrical connections from moisture and water. If the cleaner falls into the water, do not worry, unplug it and then retrieve it and let it dry fully.

1. Depending on the aquarium depth, you can add the extension tube or extension nozzle (Fig. 1 and Fig. 2).
2. Insert the unit in the aquarium and turn it on. Move the tube gently back and forth along the bottom of the aquarium.
3. Work gravel tube so that a continuous flow of gravel is picked up and returned to the bottom, moving to new areas as water changes from cloudy to clear.

Note:

• If the pump impeller in this cleaner is clogged with large debris, please loosen the impeller nut counterclockwise and pull the holder out, then you can clean debris from inside.
• The pump must be positioned below the minimum waterline before starting it.

Tips:
It’s normal for your water to appear “not so clear” after a gravel vacuum and everything has been stirred. It should clear within 24 hours or less with good filtration. If you have live plants, we suggest that you vacuum very gently over the top of the gravel. If you have large ornaments, please remove them from time to time and again vacuum lightly.

Water Changer

1. Remove the filter element top cover 4 and connect siphon cap 3) to the unit. Ensure the other end of the hose is placed inside a bucket.
2. Insert the unit in the aquarium and turn it on. The Siphon action will automatically start.

NOTE:

• It is recommended to change up to a maximum of 25% of your total aquarium water every 2 to 4 weeks.
• Removing too much water at one time can disturb the natural aquarium balance.

Filter Element Maintenance

1. Pull out the filter element. The cleaner itself can remain in the aquarium.
2. Remove the end cover pieces from both ends of the filter elements.
3. Take filter-nets off the filter element, and rinse it under running water to thoroughly remove any trapped dirt or debris.
