The Helmer Plasma Thawers are equipped with a unique disconnect drain valve system to empty the
chamber bath quickly and easily. The built-in quick drain system provides for frequent and fast
draining of the chamber - it can even be done daily - which will greatly help in maintaining a clean
chamber. The procedure for draining the chamber bath is as follows:
Caution:
For safety purposes turn the power switch OFF
before draining the chamber bath.
1) Place the open end of the drain hose securely into a sink or drain.
2) Push the other end of the drain hose with the coupling valve into the drain plug that is
located on the left side of the unit towards the back, until it "clicks" securely in place. The
chamber water will immediately begin to flow out of the chamber until it is empty. Squeeze
the tubing just after the coupling and release to remove any air pockets, improving the speed
of draining.
3)
After the chamber bath has fully drained, press down on the button located on the top of the
drain plug to disconnect the drain hose.
If draining to the right side of the unit, contact Helmer and request a drain tube "U-Fitting Assembly."
This will allow the drain tubing to be easily run to the right side of the unit.
G. Plasma Overwraps
Included with the unit is a dispenser box of 250 Helmer Plasma Overwraps. The disposable Plasma
Overwraps protect frozen random and apheresis plasma against contaminants, as required by AABB
standards, and isolate a broken FFP bag. To access the Plasma Overwraps carefully remove the
perforated section at the one end of the dispenser box and place the dispenser box into the plastic
holder on the side of the unit. Individual Plasma Overwraps can now be easily removed from the
dispenser box as needed.
Carefully fit a frozen plasma bag into a Plasma Overwrap and place it into one of the compartments in
the Basket Assembly. Make sure that the metal finger tab on the top of the Basket Assembly is
inserted through the slot at the top of the Plasma Overwrap - this will prevent the Overwrap from
falling down into the chamber.

H. Chamber Cover
The chamber cover is designed to aid in the reduction of airborne contaminates, bacterial growth, and
water evaporation. The chamber cover is intended to be used only during those times that the
