Tygon tubing and two hose clamps in the pump accessories kit. Place the hose
clamps over the tubing, and connect one end of the tubing to the pump inlet
barbed fitting and the other end to the barbed fitting on the elbow of the
chemical trap. Use a 5/16” hexdriver or a regular screwdriver to tighten the hose
clamps.
Step 4 - Install the Pump Outlet Fitting
The RV3 pump can be equipped with either a charcoal filter to remove oil mist
from the pump exhaust or a barbed outlet fitting for connecting tubing to the
pump exhaust for venting to a fume hood or house vacuum.
Place the centering o-ring on the pump outlet fitting, place the barbed fitting on
the o-ring. Place the clamp over the outlet fitting, o-ring and barbed fitting and
secure with the screw and wing nut. If the charcoal trap is not used, connect a
length of Tygon tubing over the barbed outlet fitting and place the other end of
the tubing in a fume hood.
To install the charcoal trap, locate the Allen wrench and mounting bracket in the
charcoal trap kit. Use the Allen wrench to remove the two screws on the front of
the top plate of the pump. Insert the screws through the holes in the bracket and
connect to the pump with bracket’s clip on the same side as the pump outlet
(Figure 4-2). Locate the charcoal trap, the short length of clear Tygon tubing and
two hose clamps. The charcoal trap is shorter than the Hopcalite trap used on the
pump inlet. Place the hose clamps over the tubing, and connect one end of the
tubing to the pump outlet barbed fitting and the other end to the barbed fitting on
the elbow of the charcoal trap. Use a 5/16” hexdriver or a regular screwdriver to
tighten the hose clamps.
Step 5 - Install the Chemical Trap and Vacuum Hoses
Place a hose clamp over the end of the vacuum hose (Tygon tubing with black heat
shrink and a metal fitting on one end), and connect the hose to the barbed fitting
