How to use

To replace the filter head, disconnect power to the filter and close any intake and output valves or clamps to stop water flow. Remove hoses from the existing head, drain remaining water from the canister, then unfasten the head from the canister body according to the manufacturer’s service instructions. Position the replacement head, ensuring O-rings or gaskets are correctly seated, align the ports with the corresponding hoses and secure the head to the canister body. Reconnect hoses and valves, open the valves or clamps, prime the filter if required by the model, then restore power and check for proper flow and any signs of leakage.

Usage recommendations

Inspect O-rings and gaskets during installation and replace them if they show wear. Use manufacturer-approved hose sizes and tighten hose clamps evenly to avoid deformation. After installation, monitor the filter for a short period to ensure correct sealing and normal water circulation before leaving the aquarium unattended.
