configurations, see “Instrument Placement for Bump Testing or Calibration” on
page 47 for more information and suggestions for manifolding.
Each SDM-E2 is shipped with exhaust tubing, GAS 1 and GAS 2 tubing, T-fittings,
and a check valve. Be sure to set aside one 10 foot length of exhaust tubing to direct
the exhaust to a window. Use the other provided 10 foot lengths of tubing to build the
manifold.
Exhaust Tubing
Reference Figure 11 for the instructions below.
1.
Cut a 1-2” piece of tubing for each SDM-E2 and connect it to each station’s
exhaust fitting.
2.
Connect the provided check valves to the short pieces of tubing already
installed at the exhaust fittings. Be sure that the arrows that appear on the
check valve are pointing away from the exhaust fitting.
3.
Cut a 2-3” piece of tubing for every SDM-E2 except the first one and connect it
to the other end of the check valve.
4.
Insert T-fittings into the tubing so that the remaining two ports on the T-fitting
are perpendicular to the exhaust tube and check valve.
5.
For the first SDM-E2, cut a 9-10” piece of tubing and connect it from the check
valve on the first SDM-E2 to the closest port on the second SDM-E2’s exhaust
T-fitting.
6.
Use one of the provided 10 foot lengths of tubing and connect it to the T-fitting
on the last SDM-E2. If a longer exhaust tube is needed, it can be ordered from
RKI Instruments or found locally. The maximum recommended exhaust tube
length is 30 feet.
7.
For the remaining SDM-E2s, cut 6-7” pieces of tubing and connect the
remaining T-fittings.
