TMC Reef Flow 2.0 1000nano Installationsanleitung Seite 9

Orange LED Flashing = Pump error
An orange flashing LED on the controller indicates a pump error. In this instance:
• Check motor & check controller
• Check PSU
• Check all connection cables and power cord to ensure all are undamaged and
connections are correct
• Check impeller for signs of blockages/damage and ensure the Reef Flow 2.0 nano is
fully submerged
Caution: Always isolate the PSU from the mains electricity before installing or carrying
out any maintenance to the pump.
Regular maintenance will prolong the life of your pump and we recommend that you
clean it frequently to avoid any loss in performance or damage to the motor. Ensure algae,
marine fauna and any other detritus does not foul or block the blades of the impeller or
the guard as this will cause excessive noise and will damage the motor. A blocked impeller
could also reverse the flow direction, causing the pump to draw in water rather than pump
it out.
The impeller should be regularly checked for signs of degradation and replaced as neces-
sary. Please note: The impeller is not covered under the guarantee.
The pump comes apart easily for maintenance.
1. Unplug the pump from the mains electricity supply.
2. Carefully slide the magnet from the outside of the aquarium.
3. Remove pump from aquarium.
4. Gently twist and remove the impeller guard.
5. Remove impeller, and clean with fresh water.
6. Rinse all parts with fresh water, and use a soft brush to remove any debris/detritus
inside.
7. Inspect for wear and tear.
Useful tip: if your pump is covered heavily with coralline algae, soak in a mild acid, such
as white vinegar, and scrub off algae before attempting to open. Rinse with fresh water
before use.
