How to clean the Remote Tank Switch

Like with the S1-200 and the S1-700 pump, the Remote Tank Switch (RTS) should not be used in extremely dirty, sandy or muddy water.

If the pump is operated with liquid under normal conditions, it should not be necessary to clean the Remote Tank Switch.

For more information read the following article:

Water quality requirements for S1 systems

WARNING - Disconnect power from the controller before performing any installation, inspection, maintenance or cleaning activities on the motor or pump.

Required tools

Screwdriver (crosshead)

Disassembly steps

Remove the four screws on the top of the Remote Tank Switch using a crosshead screwdriver.

Remove the gasket. Inspect it for damage and clean it if necessary.

Remove the paddle and make sure the spring is not jammed. Rinse or clean if needed.

Inspect the inside of the Remote Tank Switch to ensure it is free of any dirt or obstructions. Clean if necessary.

If any part is damaged, the Remote Tank Switch must be replaced. Please contact your authorized distributor.

Assembly steps

Important: Incorrect assembly will prevent the Remote Tank Switch from working properly.

Ensure that the paddle spring moves freely in the same direction as the flow inlet.

Reinstall the gasket carefully.

Align the direction of the arrow on the Remote Tank Switch with the arrow on the non-return valve (matching the flow direction) and tighten the top chamber with the four screws. Apply a torque of 2 N.m [1.5 lbf-ft].

Sensor Error Remote Tank Switch	Flashing	Solid	The Remote Tank Switch accessory is clogged or damaged.	Inspect the Remote Tank Switch for clogging. Follow the inspection and cleaning steps described above on this webpage, and check for any damage.	If the Remote Tank Switch is not damaged, it will work properly once it has been cleaned and reinstalled. If it is damaged, contact your authorized distributor to replace the Remote Tank Switch.
Low power 1, 2	Flashing	Flashing	A Remote Tank Full Switch accessory is installed, but the "Low power 2" event prompts before the controller identifies a full tank.	If a Remote Tank Switch is installed and the system operates at a low total dynamic head (TDH) compared to the maximum lift of the pump, the pump might stop with a "Low power" error due to the closed float valve before the controller starts to evaluate the "Remote Tank Switch" event. To resolve this, reduce the default value for the “Start-up time” in the S-Connect app: Go to Settings → Advanced Settings → Tank Switch → Remote Tank Switch → adjust the Start-up time to a lower value.	The controller will retry every 2 minutes automatically. You can also restart it manually by toggling the switch off and on.
