Component Orientation & Hose Connections
The relative position of the CentriVap Cold Trap and the vacuum pump is critical.
The Cold Trap should always be placed before the vacuum pump. Air to cool the
refrigeration system of the Cold Trap is drawn into the right side of the Cold Trap
cabinet and exhausts out the left side of the cabinet. A minimum of 3" should be
allowed between the sides of the Cold Trap and the adjacent wall surfaces.
Restriction of the airflow through the cabinet during operation could adversely
affect performance.
Once positioned properly, the system can be connected with the hoses provided.
Attach one end of the hose to the evaporator and the other end of this hose to one
of the barb fittings on the Cold Trap Cover Assembly. Secure the hoses with the
clamps supplied. Attach another hose to the remaining barb fitting on the Cold
Trap Cover and clamp securely. If the accessory Secondary Trap is not used,
attach the other end of this hose to the inlet port on the vacuum pump. If the
accessory Secondary Trap is used, install the Secondary Trap as explained in
Chapter 5: Accessories for Your CentriVap Cold Trap.
WARNING: Solvents used in the Cold Trap can cause skin, eye, respiratory
and digestive system disorders. Locate the Cold Trap inside a fume hood. It
is recommended that the vacuum pump be located inside a fume hood or
other laboratory ventilation device if hazardous solvents are being used. If
this is not possible, the vacuum pump should have a hose attached to the
exhaust port and the other end of the hose should be positioned inside the
fume hood or ventilation device.
