Operating Manual
1. Connect the gas inlet tubing to the gas supply and route it to the
detector.
2. Connect the gas exhaust tubing to the ventilation and route it to the
detector.
3. Check the length of the gas tubes.
The gas tubes should not form siphons but go straight to the
detector. If the gas tubes are longer than required, use a tubing
cutter to cut the tubes straight to the required length. Make sure
that the cut is at a right angle to the length of the gas tubes.
4. Connect the gas tubes to the elbow connectors. Mind the correct
orientation of the elbow connectors.
a) Connect the gas inlet tubing to the gas inlet elbow connector.
b) Connect the gas exhaust tubing to the gas exhaust elbow
connector.
