The high polish finish inside the Refrigerated Chamber is designed to minimise the
adhesion of particles to the side walls.
Do not use scouring powder or harsh detergents or you will degrade
the polished finish

TO CLEAN ThE KNIfE hOLDER
Remove the knife or blade before cleaning Knife holder
It is important to keep the Knife Holder clean. To clean behind the clamp plate, drip
xylene behind the clamp plate to loosen any wax build up. Remove any wax build up
with a fine brush.

DEfROSTING
Remove the specimen from the cryobar before defrosting. The cryobar
will reach temperatures of +80°C during the Defrost cycle
The accumulation of frost within the Refrigerated Chamber reduces the efficiency of the
refrigeration system. Press
[IMMED DEfROST] if the cooling coils are frosted up, or if
the performance of the refrigeration unit deteriorates.
Alternatively, use the ‘DAY 8’ setting of the timer to defrost
for 15 minutes at a regular time each day. The temperature
of the Refrigerated Chamber will not normally rise above 0°C.
Note
1 This cycle is used to remove the build up of small amounts of ice around the
main evaporator coil and the cooling fins at the rear of the cryo-chamber.
For a thorough defrost of the complete instrument, use the Fumigate cycle every
week. This takes about 5 hours and will totally defrost all of the pipes. The resulting
condensate will flow into the waste bottle and the temperature of the cryo-chamber will
rise above 0°C during the cycle.
