SUNSUN support FAQ

Common questions about manuals, registration, and support for this brand.

  • Why is my SUNSUN aquarium heater displaying an E1 error?

    The E1 error code on SUNSUN heaters, such as the GR-500C, typically indicates that the unit has been removed from the water or the water level is too low. The heater automatically shuts off to prevent damage; ensure it is fully submerged to resume operation.

  • How do I adjust the range on the SUNSUN wireless dog fence?

    For models like the AS01 or D-27, use the Signal Range Set Button on the transmitter. You can select from 5 levels, corresponding to a purely circular play area with a radius ranging from approximately 100 to 500 feet.

  • Can SUNSUN pond pumps be used in saltwater?

    Yes, many SUNSUN pumps, such as the CET-8000 'SuperECO' adjustable pump, are designed with ceramic shafts and components suitable for use in both freshwater and saltwater (seafood) aquariums, as well as garden ponds.

  • How often should I clean my SUNSUN canister filter?

    Maintenance frequency depends on the bio-load of your tank, but generally, the mechanical filter media (sponges/pads) should be rinsed every few weeks using aquarium water (not tap water). Detailed disassembly instructions are found in the user manual for your specific HW-series model.
