Setting up the StP420
Selecting a Site for the STP420
The flow resistance in the STP420 is negligible (<0.01 Pa at 1 m3/h).
The required negative pressure does not depend on the STP420, but on
the flow resistance of the suction hose. In the laboratory, the permanent
negative pressure must be maintained at the connection point of the
fume hood or the exhaust system, and be lowered according to the tube
length and flow rate.

You must exercise caution when opening the lid of the rotational
chamber if it contains formaldeyhyde, to avoid exposure.
• To guarantee sufficient ventilation, make sure the instrument can be
sited the following distances from walls or other instruments:
• Rear: 30 cm/12 inches
• Left side: 30 cm/12 inches
• Right side: 20 cm/8 inches
• All interfaces for peripherals (for example, remote alarm system) are
located on the left side of the device. These must be easily accessible.
• The site must have a heat emission no greater than 1200 W. Make
sure the site has adequate means to dissipate heat.
• There must be a suitable power source for optimal operation.
Emergency power is also recommended.
Note!
The equipment has a 1.5m/60-inch power cord, with a three-wire ground
plug.
