Cooling tube
CAUTION Hot surface
The cooling tube can become hot while in use.
Before installing the cooling tube, you need to determine the
cooling tube model that you have, and whether you need to
add air flow or not.
To identify the cooling tube model:
Figure 40 Cooling tube models P920 (left) and P921, P922, P923, and P924 (right)
Tables on the next page indicate the need for air flow based
on cooling tube model, process generated temperatures, and
ambient temperature.
NOTICE
The cooling tube is not a pressurized vessel. As such,
it should not be exposed to air pressures exceeding
10 psi (0.7 bar).
Also, to prevent air pressure build-up, the bottom air
outlet should NEVER be blocked in any way. (If a tube
extension is used to redirect air flow, the tube itself
should neither be blocked nor connected to anything
else.)
