WARNING:
NEVER use the water cooling
coil without a gas flow into the
chamber. Not using inlet gas
during cooldown creates a
vacuum pressure which could
cause extensive damage to the
oven.
CAUTION:
Design the drain system to prevent operator injury from high temperature or pressure
buildup. Piping must be able to withstand short periods of up to 650 F (343 C)
temperatures. Drain lines should be insulated or warning labels installed that a hazard
exists.
WARNING:
Never allow drain to be plugged as a hot oven will generate a small amount of steam when
the water is first turned on. Steam burns.
