Figure 39: Quick Release Valves
Firmly attach the quick release barbs to your chiller supply hoses ensuring a leak free
connection.
With the power turned off , ensure the 10 way dry block is placed in the control unit of the
Omni Reaction Station.
Note: For 25mm glassware remove the 24mm reduction ring located in the vessel port of the
dry block.
Place the reflux unit over the dry block ensuring the legs of the reflux unit sit over the rim of
the dry block cartridge.

Connect the coolant supply pipe work to the reflux head using the ‘quick release’ pipe
fittings
supplied. The connection is made by inserting the quick release fitting into the elbow joint
coupling. Ensure the release button is in the down position before attempting to make the
coupling. (See Figure 39: Quick Release Valves).
Note: The chilled coolant supply must not exceed 3 bar pressure. Ensure there is a free flow
of coolant through the reflux head. Do not turn on the coolant supply until both hoses have
been connected. Condensation will form on the surface of the reflux unit when the coolant
supply temperature is lower than that of dew point.
Turn on the coolant supply and check for any signs of coolant leakage. Allow 15 minutes for
the reflux head to cool before use.
Charge up to ten vessels with chemistry and add stir bars AZS4206 (one per glass vessel).
Screw fasten the reflux caps onto the charged flasks. Ensure the valve taps on each reflux
cap is in the closed position.
Note: Using the inerting facility is optional.
Place the charged glass vessels containing the required chemistry into the dry block by
lowering them through the reflux unit.
Connect a piece of inert tubing between each inerting cap and reflux gas output port.
