Chapter 4: Using Your Freeze Dryer
Defrosting
The following procedure should be followed when
defrosting the collector coil:
1. Pull the collector chamber drain hose out from
the front panel of the unit and remove the drain
plug. Place the drain hose in a suitable
container to collect the condensate that will be
defrosted off the collector coil.
2. Press the DEFROST switch on the control
panel. The green annunciator above that
switch will illuminate. Allow unit to operate in
this condition until all condensate is defrosted
from the collector coil. Dispose of the liquid
appropriately.
3. Flush the collector chamber with water and
wipe chamber dry.
4. If rapid defrost is desired, pour warm water
over the collector coil.
Do not fill the
chamber above the collector coil as water
will enter the vacuum stand pipe and drain
into the vacuum pump.
5. Press the DEFROST switch, the green
annunciator will be off. Reinstall the drain
hose plug and slide drain hose back into
cabinet through the front panel. Dispose of the
liquid appropriately.
Utilization of acid requires
immediate cleaning and
neutralization after defrost or
physical damage to the collector
chamber and collector coil will
result.
Do not attempt to chip ice from
collector coil as damage may
occur to the coil.
