Safety Instructions
Outdoor Operation and Electrical Safety
Skimmers not for outdoor use; ensure plug placement avoids water damage.
Operating Conditions and Water Parameters
Use GFCI; do not run without water; observe water level and temperature.
Preparation and Setup
Mounting Skimmer Components
Fit suction cups, remove cap, screw on Hydrofoamer, connect hose, and mount elbow.
Installing Outlet and Filtration Accessories
Mount outlet pipe, then fit outlet fleece or post-filter.
Model-Specific Water Levels and Outlet Pipes
Specifies water levels and outlet pipe lengths for different skimmer models.
Post-filter Usage and Maintenance
Outlet Fleece vs. Post-filter
Outlet fleece removes micro-bubbles; Post-filter ensures mechanical filtration.
Installing and Cleaning the Post-filter
Mount, rinse, adjust height, and clean post-filter bag weekly.
Cabinet Placement and Environment
Skimmer Accessibility and Space Requirements
Ensure easy access and sufficient space above the skimmer for cup removal.
Optimal Placement Zone
Place skimmer in a quiet water zone, away from drain outlets or air ejectors.
Initial Operation Procedures
Observing Water Flow and Initial Setup
Water rises to outlet pipe; skimmer needs no air/water adjustments from factory.
Managing Initial Overfoaming
Reduce air output with a hose clamp if skimmer boils over during initial use.
Start-up Phase Observations
Initial Noise Reduction and Foam Cup Checks
Running noise decreases after 2 weeks; check foam cup daily during aquarium start-up.
Marine Aquarium Start-up Foam Characteristics
Foaming water is light and aqueous in marine start-up; foam color varies with organic load.
Performance Adjustment with Booster Ring
Using the Booster Ring for Fine-Tuning
Booster Ring adjusts height and internal water level for performance tuning.
Booster Ring in Post-filter
Post-filter is height adjustable and integrates a Booster Ring.
Ozone Connection and Operation
Air Pump Requirement for Ozone
An additional air pump is necessary to mix air and ozone for the skimmer.
Connecting Ozone Input
Connect the silicone hose to the nipple for ozone input.
Weekly Maintenance Procedures
Skimmer Cup Cleaning and Fluid Check
Check skimmer fluid, empty and clean the cup, keeping the Hydrofoamer operational.
Strainer and Post-filter/Fleece Cleaning
Clean the skimmer strainer and the post-filter or outlet fleece.
Annual Maintenance and Disassembly
Disassembly and Component Removal
Disconnect hose, unscrew Hydrofoamer, remove pipes, disc, and other parts.
Cleaning, Reassembly, and Restart
Rinse parts, clean air route, reassemble, and restart the plant.

Troubleshooting Common Issues
Water Flow Issues During Initial Operation
Water not rising into chamber; incorrect pipe or new skimmer.
Foam Not Rising Into Reaction Pipe
Cause: Incorrect outlet pipe. Remedy: Fit correct outlet pipe.
Foam Production and Rising Issues
Cause: New tank or skimmer. Remedy: Wait for load increase or break-in period.
Low or High Water Levels Affecting Foam
Adjust water level or use Booster Ring for low/high levels.
Soiled Pump or Nozzle System
Cause: Pump or nozzle system soiled. Remedy: Clean pump and nozzle.
Clear Skimmed Liquid Boiling Over
Cause: New unit or recent cleaning. Remedy: Reduce air volume.
Decreasing Foam Formation Over Time
Cause: Aquarium maturing, less waste. Remedy: Use Booster Ring to increase sensitivity.
Soiled Water Inlet or Nozzle System
Cause: Inlet or nozzle system soiled. Remedy: Clean inlet, pump, nozzle, or disassemle skimmer.
Hydrofoamer Not Operational or Intermittent
Cause: Hydrofoamer not working or blocked. Remedy: Check, clean, replace parts or motor block.
Skimmer is Loud Due to Water Level
Cause: High water level allowing water into air path. Remedy: Adjust water level.
Soiled Dispergator or Defective Pump
Cause: Dirty Dispergator or faulty pump. Remedy: Clean Dispergator, check impeller, replace parts.
Foam Not Rising Due to Turbulent Zone
Cause: High flow or air bubbles in filter zone. Remedy: Find a quieter location.
Skimmer Placement After Biological Filtration
Cause: Filter systems can interfere. Remedy: Do not place at the end of a filter chain.
