INSTALLATION

Location

1. Mount the switch vertically as shown in Fig. 1 (wires located uppermost). Locate the switch as close to the pump as possible to ensure the same water level.
2. Prepare a mounting block. Do not fasten the switch directly to the hull. The mounting block should be a minimum of 1 0mm(3/8″) thick marine plywood epoxied to the hull.
3. The switch base may be located up to 6mm (1/4″) higher, but NEVER located lower than the base of the pump.

Mounting

1. Use the switch base (Fig. 1) or mounting ears (Fig. 2) as a template to mark pilot holes in the mounting block.
2. Set drill depth gauge to avoid drilling through the hull. Drill two 3mm (1/8″) diameter pilot holes.
3. Fasten the switch onto the mounting block with #8 x 1/2″(3.5mm diameter x 13mm) stainless steel screws (not supplied).

Testing

1. After installation, press and hold your finger in the two recessed places for 3 seconds.
   • If the wiring is correct, the pump activates.
   • Remove the top finger, the pump stays on.
   • Remove the bottom finger, the pump should turn off after a short delay. Fig 3 – Testing Switch
2. Test with water in the bilge to confirm that the pump turns on and off properly. If not, reposition the switch to allow for activation.
3. Regularly touch the two sensing points with your finger to check whether the function is valid.
4. When there is dirt residue on the sensing point after long-term use, please clean it up in time to avoid the failure of the switch function.
