It is important to keep the distance between the unit and the instrument to be cooled as short as possible. Tubing
should be straight and without bends. If diameter reductions must be done, they should be made on the inlet and
outlet of the instrument to be cooled, not on the chiller.
When fittings must be changed or the chiller is not used for a long period, be sure to drain all liquid out of the unit.
Shut down the unit at first, then put a cup on the ground and disconnect the fitting from the instrument cooled
then let the fluid in the tank flow out into the cup and disconnect the fitting on the chiller. Before positioning the
unit in the storage be sure the drain tap is closed.
