• All vacuum/pressure pumps generate heat, even
under normal operating conditions. To avoid serious
burns, never touch the head parts or tubing during
and immediately after operation.
• If higher vacuum or pressure is required, use the
High Output Vacuum/Pressure Pump (WP6211560,
WP6222050, WP6210060).
Usage Guidelines
• Always use the Millex
®
-FA
50
vent filter and
1/4 inch silicone tubing included with the pump when
applying vacuum. This will prevent liquids or vapors
from entering the pump. A properly attached
Millex
®
-FA
50
vent filter is illustrated in Figure 1.
• For maximum protection of the pump, use the
Millex
®
-FA
50
vent filter AND a vacuum trap to protect
the pump from vapors and gases. The vacuum
trap consists of a 1 liter filtering flask (Cat. No.
XX1014705), No. 8 stopper (XX1014708) and
silicone tubing. Additional tubing is available as
Cat. No. XX7100004. This assembly is illustrated
in Figure 2.
• Never pump or draw liquids through the pump. This
will damage the pump. The filter flask and vacuum
trap should be emptied after each use.
