The CO
2
will bleed out of the cooling nozzle, into the chamber. When all
the CO
2
is out of the system, the flow of gas from the nozzle will stop.
3. Using a wrench, disconnect the Transfer Hose (loosen the large brass
fitting) from the CO
2
tank.
4. Replace the empty tank with a fresh Liquid CO
2
tank. Then, using a
wrench, reconnect the transfer hose.
5. Turn “OFF” the “COOL” switch on the front panel. This will close the Cool
Valve.
6. After the system is turned “OFF”, open the manual valve on top of the CO
2
cylinder.
The Transfer Hose and Cool Valve will now be pressurized. If any leaks
occur, close the manual valve on top of the CO
2
cylinder and tighten any
fittings that are leaking. Open the manual valve and recheck for leaks.
4.2.1.5 Specifications and Performance
1. Cooling Capacity:
The Model 563 CO
2
Gas Cooling System, when used in the ETS Model
518 Chamber with a full 50 lb. CO
2
tank, will provide cooling to at least 32
°F (0 °C). The total CO
2
consumption rate for the system depends upon
the temperature that is being maintained.
The following chart shows the approximate consumption rate for the
system at different temperatures, assuming a full 50lb. CO
2
tank and room
ambient temperature of 72 °F (23 °C).

NOTE
These consumption rates are for maintaining the above temperatures. When
lowering the temperature from room ambient to the set-point temperature, the
consumption rate will be higher. The consumption rate will be as shown once
the set-point temperature is reached.
