This version has a straight outlet with 8 mm compression fittings (RVS 8) on both sides, coupling nut type M-MS and olive type D-MS. It comes with 2 hose adapters, pipe socket RST 8 x 8 mm hose nozzle. The housing is marked Alde Leak Detector 4071.

How it works

• quick leak check of the whole system after the tester at the press of a button
• a leak shows as bubbles in the sight glass
• the glycol mixture supplied allows testing also below 0°C
• maximum working pressure 2 bar, pressure loss below 1 mbar
• the manufacturer recommends testing every time the gas system is used and at every cylinder change

Connections and installation

• suitable for all low pressure LPG systems in marine applications
• 8 mm compression fitting (RVS 8) on both sides with coupling nut type M-MS and olive type D-MS
• the 2 hose adapters RST 8 x 8 mm nozzle let you connect the tester to a gas hose
• as close as possible to the regulator outlet, ideally in the gas cylinder locker; otherwise in a place protected from UV light and water
• always before any gas fittings or appliances, vertically with the sight glass visible, following the flow direction arrows
• fixing screws and reinforcing sleeves for copper tubes are included

How to test

• open the main valve on the gas cylinder
• switch off all gas appliances and wait about 60 seconds until the flame failure devices cut off the gas (a click can be heard)
• press and hold the red button at the bottom for at least 10 seconds, longer in large systems
• wait at least one minute for the first bubble; if the following bubbles come more than 10 seconds apart, the system can be deemed sound
• if the tester shows a leak, do not use the system; find the leak with soapy water or a leak detection spray

Topping up and checking the tester

• close the cylinder valve, unscrew the sight glass and fill to the top mark, then refit the sight glass and check the gasket
• after filling, do not turn the tester upside down as the liquid may run out
• after topping up, check the tester itself for leaks
• check the liquid level regularly
• function check: run an appliance with low gas consumption (e.g. the fridge) and press the button fully - bubbles mean the tester works
