Page 3: Safety Warnings
SAFETY WARNINGS WARNING – ELECTRIC SHOCK The Aqualeak 10K operates using mains voltage that is dangerous to life. Before work commences, make sure that the mains power is isolated by a competent person and a Lock Out and Tag-Out procedure has been followed. Prove the mains supply is de-energised with a suitable multi-meter which has been checked with a proving unit. - Page 4 10K manual Light Emitting Diode Least significant bit Metre minutes millimetre Most significant bit msec milli-second Newton metre Number Power Supply Unit Remote Terminal Unit seconds Volts (Alternating Current) Volts (Direct Current) Watts Issue 1.0, 31st July 2019 Page 4...

10K uses sensing equipment (sold separately) to detect the presence of water and other liquids. If a leak is detected, an alarm is activated, the distance to the leak is displayed, and the Aqualeak 10K can report the presence of the leak to a Building Management System (BMS). -
Page 8: Description
10K manual DESCRIPTION Capable of accommodating up to 2500 m (8200 ft) of sensor cable, the Aqualeak 10K has an audible alarm and can communicate via Modbus. As a stand-alone solution, the Aqualeak 10K provides alarm notification, and numeric distances to leaks or problems, on its front panel. -
