Introduction
The PASCO scientific Model TD-8556A Steam Genera-
tor is an efficient source of steam and hot water for the
student lab. The one liter stainless steel tank is electrically
heated with a variable output of up to 400 Watts. The dan-
gers of overheating are eliminated by the thermal circuit
breaker that disconnects the power if the water boils dry.
Operation
➤ ➤ ➤ ➤ ➤CAUTION:
➀
The stainless steel tank gets HOT when the unit
is on.
➁
DO NOT immerse the unit in water.
➂
ALWAYS plug into a grounded receptacle. Do
not use a three-to-two-prong adaptor.
Operation is simple. Plug the unit into a standard 115/220
VAC, 50/60 Hz outlet. Fill the one liter tank approxi-
mately 1/2 to 3/4 full of water and place the rubber stop-
per over the top. Flip the ON/OFF switch to ON. The
switch will light to show that power is entering the unit.
Turn the power dial clockwise, and the heater will click
on. Set the dial to 8 if you want steam or boiling
water, to a lower setting if you want hot but not boiling

Fill with water,
1/2 to 3/4 full.
To direct the output of
steam, attach 1/4-inch
inside diameter tubing. For
maximum output of steam,
block one opening.
water. At full power, it will take 10-15 minutes to bring
3/4 of a liter of water from room temperature to boiling.
A baster is provided for removing hot water from the tank
for use in experiments. If you need steam, attach plastic
tubing (1/4-inch inside diameter) to the tubes on the rubber
stopper—two experiments can be performed simultane-
ously. For the full steam output of approximately 10 grams/
minute, block the tubing on one side with a tubing clamp.
If the water in the tank runs low, the thermal circuit
breaker will cut off the power to the heater and the LOW
WATER light will come on. In this case, just add more
water to the tank. When the tank cools sufficiently, the
heater will restart automatically.
If the ON/OFF switch ever fails to illuminate when
switched to ON, check the fuse on the front panel of
the unit.
➤ ➤ ➤ ➤ ➤IMPORTANT: If the fuse is blown, replace
only with a similarly rated fuse. For 115 V use 5
Amp, 250 V, for 220 V use 2.5 Amp, 250 V.
