2. TESTING INSTRUCTIONS
A. Open the main valve on the gas bottle.
B. Shut off all LPG burning appliances. Extinguish the burners on all units equipped
with an ignition safety device. Then wait about 60 seconds until the ignition safety
device has cut out the gas supply (a click should be heard). By setting the gas
valve to the 'ON' position on appliances with an ignition safety device the sound-
ness of the ignition device is also tested.
C. Depress the red test button in the bottom and hold it down for a minimum of 10
seconds, in larger systems this will take longer time. Leaking bubbles may immedi-
ately appear in the sight glass (see fi gure 3) if there is any leakage in the system.
D. If, through the presence of bubbles, the leak detector shows that a leakage exists
in the system, then check the location of these with a soapy solution or a leakage
spray. Spray on to all connections and joints until the leakage is located. If no leak
can be found on joints or couplings the leakage may exist in some safety device.
IMPORTANT! Do not use the system if a leakage is detected.
3. TOPPING UP THE LIQUID
A. Close the regulator valve on the L.P.G. cylinder.
B. Unscrew the sight glass. Cut a corner off the glycol sachet supplied (art.no. 4070
125) and fill to the top mark on the sight glass. Check that the gasket is in the cor-
rect position and then screw sight glass back into place.
C. After topping up the liquid, the gas tightness of the leak detector should always
be tested. The leak detector is selftesting, i.e. bubbles appear in the sight glass if
there is a leak in the tester. Adopt the same procedure as for a normal test.
D. The level of liquid in the detector should be checked regularly and topped up when
required.
IMPORTANT! When the glycol liquid has been topped up the leak tester
should not be turned upside down as the liquid may run out.
4. CHECKING THE FUNCTION OF THE LEAK DETECTOR
A. Start up a unit that uses a small amount of L.P.G. eg. a refrigerator.
B. Depress the red testing button as far as it will go. If bubbles appear in the sight
glass the detector is working. If no bubbles appear the detector is out of order. It
may be blocked with dirt from the connection pipe work. In event of failure contact
your dealer and have the system checked.
