Deckma Omd11 Manual Official

Verify the display reads 0 during the clean water flush. If it deviates slightly, use the front panel zero-calibration adjustment.

Wire the alarm relays to the OWS automatic three-way bypass valve. If the ppm exceeds 15, the relay must instantly redirect the discharge back to the bilge holding tank.

Allow the display to stabilize. The reading should be 0 ppm (±2 ppm).
