Chapter 4: Using Your Freeze Dryer
collected frozen solvent will obstruct the flow of
vapor to the collector chamber. At this point the
unit should be defrosted. First, release system
vacuum by turning the plastic knob on a valve to
the “vacuum”/open position or by pulling the
collector chamber drain hose plug. Now turn the
vacuum and refrigeration switches on the control
panel to “off.” When operating in the automatic
start-up mode, the vacuum automatically shuts off
when the refrigeration switch is turned to “off.”
Defrosting
The following procedure should be followed when
defrosting the collector chamber:
1. Pull the collector chamber drain hose out from
the side on the unit and remove the drain plug.
Place the drain hose in a suitable container to
collect the condensate that will be defrosted.
2. Remove the freeze dry chamber or manifold
and pour warm water over the ice in the
collector chamber. Do not fill the chamber
more than 3 inches from the top as water will
enter the vacuum stand pipe and drain into the
vacuum pump. Dispose of the liquid
appropriately.
3. After all condensate is defrosted from the
collector chamber, flush the chamber with
water and wipe chamber dry.
4. Reinstall the drain hose plug and slide drain
hose back into cabinet.
Utilization of acid requires
immediate cleaning and
neutralization after defrost or
physical damage to the collector
chamber will result.
Do not attempt to chip ice from
collector chamber as damage may
occur to the chamber.
