7.3. Cleaning
Cleaning of acrylic components use only mild detergents solutions NEVER
solvents.
Wipe stainless steel surfaces with alcohol and then dry, do not use abrasives.
The Condenser of the CoolSafe once drained, wipe dry and then lightly
cleaned with alcohol, ensure that the drain valve is open. Do not forget to
close the valve once the condenser has dried.
7.4 Checking for Leaks on Cool Safe Freezer Dryer
Always start from the vacuum pump and work forwards towards the chamber.
1.
Check vacuum hose connection to the pump. If the pump is fitted with a
nozzle and if this is held in place with a clamp i) check that there is a centring
ring with seal fitted between the flange on the pump and the nozzle. Make
sure the clamp is tight and that the hose is pushed well onto the nozzle, and
that the clip on the hose is tight.
2.
Check the other end of the vacuum hose where it connects to the CoolSafe ,
make sure the clip is tight.
3.
The drain valve on the front of the Cool Safe also has to be checked for leaks.
First unscrew the drain valve (with black knob) all the way until its loose and
then pull towards you. The barrel of the valve then comes away from the
body. On the end of the barrel there is a white Teflon plug, make sure this is
clean and without any scratches, also wipe the inside of the valve body.
Replace the valve barrel into the body of the valve, push in and then screw
the valve completely to the fully closed position. When vacuum is applied
check that there is no leak from the drain-this can be done placing a finger
over the drain spigot, you will feel if there is a leak.
4.
Check the seal on the acrylic plate of the chamber that interfaces with the
top s/steel part of the Cool Safe. This can be done by squirting or brushing
some frothy soap solution all around, if there is a leak this will be sucked in
towards the condenser.
5.
If leak(s) are found on the seals, clean both the surface of the s/steel and the
seal, using a clean tissue slightly wetted with alcohol.
6.
Check that the lid of the chamber is located correctly, again check that the
seal is OK as previous.
