Drain System Maintenance
5. Disconnect the drain tubing from both the drain vessel and the drain outlet on
the burner end cap by loosening the clamps on each end of the tubing. Once the
clamps are loosened, the tubing should easily pull out.
6. Place the new piece of drain tubing (Part No. 02507987) next to the drain
interlock cable and carefully rewrap the spiral wrap around them both.
7. Place the drain clamp on the upper end of the new drain tubing. Then attach the
tubing to the drain outlet on the burner end cap. Tighten the clamp securely.
8. Place the other drain clamp on the lower end of the drain tubing. Then attach
the tubing to the drain trap switch assembly. Tighten the clamp securely.
9. Plug the drain interlock connector into the receptacle under the burner. Make
sure the interlock connector is plugged in all the way.
10. Go to Preparing the New Drain Tubing for Use on page 229 .
Preparing the New Drain Tubing for Use
In order for the sample introduction system to drain smoothly, the internal surface
of the new drain tube needs to be prepared. This is easily accomplished when you:
1. Aspirate a 50/50 solution of water and methanol for approximately 5 minutes.
2. Replacement and preparation is now complete.
Adding Water to the Drain Float Assembly
Enough water must be present in the drain system to fill the drain loop and to
activate the drain float assembly. If not, carry out the following procedure:
1. Loosen the drain clamp and remove the drain tubing from the drain outlet on
the burner end cap.
2. Pour about 250 mL of water into the drain tubing.
Note
This important procedure MUST be performed at this point of the drain
tube replacement process.
