The tracer-gas supply cylinder is connected to the Dosing Gas Inlet
on the rear panel of the 1303 using nylon tubing. This tubing is avail-
able from LumaSense, accessory number AF0008.
To connect the tracer-gas supply:
1. Attach one end of the tubing AF0008 to the outlet of the pressure-
regulator as recommended by the regulator manufacturer.
2. Push the other end of the tubing into the Dosing Gas Inlet stub
on the rear panel of the 1303.
After connection, slowly open the regulator’s valve and allow the pres-
sure to rise. The tracer-gas supply pressure must be within the follow-
ing range to ensure efficient dosing:
Minimum: 300 kPa (~ 3 bar) absolute
Maximum: 450 kPa (~ 4,5 bar) absolute
If you are using a pressure-regulator which displays pressure relative
to atmospheric pressure (101 kPa or 1 bar), the pressure reading
should be within the range 200 kPa to 350 kPa (2 bar to 3,5 bar).
The tracer-gas supply tubing is removed from the Dosing Gas Inlet
stub by pushing on the flange at the end of the stub, and simultane-
ously pulling the tubing gently.
2.3.4 Connecting the Sampler Outlet to the Gas Monitor
This connection uses the same tubing (PTFE, LumaSense No. AF0614)
as for the sampling tubes, section 2.3.1 . The tubing is connected to the
Outlet to Monitor stub on the rear panel of the 1303, and to the Air
Inlet stub on the rear panel of the Gas Monitor. The tubing is con-
nected as described in
section 2.3.1 .
2.3.5 Waste Air Outlet
The Waste Air Outlet stub, next to the Outlet to Monitor stub on the
rear panel of the 1303, exhausts waste air from the 1303’s sampler
system as a new sample is collected. If you do not wish the waste air to
mix with the air in the room where the 1303 is positioned, connect a
length of PTFE tubing (LumaSense No. AF0614) to the Waste Air Out-
let stub and direct the tubing to a suitable exhaust-point: for example,
out of a window.
