Hygger Electric Vacuum Gravel Cleaner HG-955 / HG-955-AC

Quick Guide

The Hygger Electric Vacuum Gravel Cleaner is designed for water changes, fish waste cleaning, and sand washing in aquariums. It features an adjustable handle (29-103cm) and a powerful water pump. Important: Always keep the water pump fully submerged during operation. Do not run the pump dry. Keep the electrical connector away from water at all times.

Assembly Instructions

The device is modular and can be assembled based on your specific cleaning needs:

• Water Pump: The base unit.
• Extension Tubes: Connect to the pump to adjust the length.
• Three-way Valve: Connects the pump/tubes to the filter housing.
• Filter Housing: Contains the filter sponge.
• Attachments: Choose between the Debris Vacuum, Brush Head, Sand Washing Head, or Sand Vacuum depending on the task.
• Outlet: Connect the soft water pipe here for water changes.

Follow the step-by-step assembly diagrams in the manual to connect the pump, extension tubes, three-way valve, and filter housing. Ensure all connections are secure.

Operating Modes

• Removing Debris: Use the Debris Vacuum or Brush Head. Ensure the filter housing is attached to catch waste.
• Washing Sand: Use the Sand Washing Head for coarse sand or the Sand Vacuum for fine sand. Keep the vacuum upright and slightly lift the device to clean horizontally.
• Water Change: Connect the soft water pipe to the outlet. You can use the device with or without attachments. For low water levels, remove the sponge pad from the sand vacuum and place it on the intake strainer to prevent impeller blockage.

Safety Precautions

• Do not run the pump dry.
• Keep the water pump completely submerged when in use.
• Do not use if the power cord is damaged.
• Keep away from children.
• Do not use in flammable or corrosive liquids.
• Operate only in water temperatures between 40°F and 95°F.
• Create a 'drip loop' with the power cord to prevent water from dripping onto the receptacle or plug.

Maintenance

• Regularly remove the filter housing and clean the filter sponge.
• The filter sponge can be replaced with other brand sponges or filter pads if necessary.
• If the pump stops working or makes noise, check for blockages in the motor or impeller.

Troubleshooting

• Pump stopped working: Check power connection, ensure the pump is not damaged, check for impeller blockage, or ensure the pump is fully submerged.
• Noise: The motor may be blocked. Take it out and clean the motor.
• Insufficient water flow: The impeller may be damaged and require replacement.
