Retaining screws
2 Push the assembly firmly sideways. Tighten the knurled retaining screws
alternately, one turn each at a time, so that the assembly is pulled up evenly
into place (see Figure 75 above). Tighten both screws firmly with the fingers
only.
3 Place a suitable wide-necked waste vessel in a convenient position at floor
level.
The waste vessel must be made of a non-glass material which will not
shatter in the event of a flashback or fire.
Locate your waste vessel in an open well-ventilated area where you can
see it.
Never locate the waste vessel in a confined space.
Use small stable vessels and empty them frequently.
WARNING
Fire Hazard.
Do not accumulate large volumes of flammable liquid.
Dispose of flammable liquids in accordance with local regulations.
4 Attach a convenient length of 9 mm ID tubing to the lower outlet of the liquid
trap.
