Power Supply Unit and DTC
With reference to Figures 2 & 3:
1. Connect the power supply cable (blue fitting) from the back of the power supply unit to the
front of the DTC, making sure that the black clip is attached (j).
2. Plug in the power supply mains cable and switch on the unit.
3. Connect the serial cable (grey) from the DTC unit (k) to the computer.
4. Fit the red shield gas line (l) between the connectors on the top of the DTC unit and the gas
delivery nozzle.
Dry-air unit connection (or alternative gas source connection)
1. Connect the white PTFE gas line from the dry-air unit to the DTC unit “gas in” port (m),
incorporating a line drier into the gas path if required.
2. To fit a line drier, remove the two blanking caps attached to the line drier (these caps are
fitted to the line drier during transit and also for storage to avoid contamination). Note: Do
not leave the line drier open to the atmosphere. Using the extra short length of PTFE gas
hose, fit the line drier into the gas circuit near to the AD51 or to the DTC, whichever is more
convenient.
3. Adjust the shroud flow rate on the DTC unit to approx.12 ℓ/min (n). The cold flow is pre-set
to 5 ℓ/min in the factory.
Note
Start the vacuum pump 1 hour prior to running the DTC. This must be done before each run.
The pump must be left constantly running whilst the DTC is in use.
We also recommend that you set up the DTC and leave the vacuum pump running for a
minimum of five hours (preferably overnight) with the speedivalve open before using the
system for the first time.
