Electrical Requirements
The CentriVap Refrigerated Concentrator requires a dedicated grounded electrical
outlet. This outlet requires a 15 Amp circuit breaker or fuse for models rated at
115V (60 Hz). An 8 Amp circuit breaker or fuse is required for models rated at
230V (50/60 Hz). 115V models are equipped with a 15 Amp NEMA 5-20P plug.
The power cord on 230V models is equipped with a NEMA 6-20P plug. If this
does not match with the available receptacle, remove this plug and replace it with
an approved plug of the suitable style.
It is recommended that an emergency switch for disconnecting the mains in the
case of a malfunction is located remote from the CentriVap. It should be outside
the room in which the CentriVap is housed, or adjacent to the exit from that room.
Location and Exhaust Requirements
The CentriVap Concentrator should be located on a surface that is stable, flat and
level.
WARNING: The CentriVap System should be located within a fume hood if
hazardous or flammable solvents are used. Heating of materials could lead
to the liberation of hazardous gases. In all cases, regardless of the solvent
used, it is strongly recommended that the vacuum pump is vented in a fume
hood. An accessory secondary trap is available to minimize the exhausting of
solvents into the atmosphere. This does not, however, negate the need to
exhaust the vacuum pump into a fume hood. Failure to properly vent the
CentriVap will expose personnel to potentially harmful chemicals.
The CentriVap Refrigerated Concentrator has not been evaluated by an
approval agency for the use of biological, radio toxins or flammable liquids
or materials.
Vacuum Pump Requirements
A vacuum pump must be provided by the user. A vacuum pump with a free air
flow rate of 90 liters per minute and 1.3 x 10
-4 mBar ultimate pressure is adequate
for aqueous samples. More volatile samples can be satisfactorily processed using
a diaphragm pump with a free airflow of 42 liters per minute and 200 mbar
vacuum. The inlet fitting on the vacuum pump must be suitable for 0.50 ID hose.
