5 .3 .3 Waste/aspiration hoses
The distillation and sample residue can be aspirated and collected separately from the cooling water.
For this purpose a separate collection tank is necessary. The collection tank must be located lower
than the instrument to guarantee proper drainage.
Connect the waste/aspiration hose to the waste outlet and place it directly into the drain (sink). For this
purpose, shorten the EPDM hose to the optimal length. In order to prevent any back-flow, the hose
may be placed maximum 10 cm into the tank.
5 .3 .4 Storage tank connection
To connect the storage tanks, proceed as follows:
• Cut the Nylflex hose into pieces of the appropriate length (use a Viton hose for the acid resistant
pump).
• Insert a FEP suction hose into the Nylflex hose.
• Push an EPDM sealing ring over the Nylflex hose.
• Now fasten the hoses to the tank with the red screw cover.
• Connect the hoses at the appropriate connections at the instrument side and secure them with the
clamps.
