Changing the Hopcalite Trap
The chemical trap contains an ozone destruction material Hopcalite and is
consumed when the ozone is removed. In order to protect the pump, it is vital that
this trap be replaced when indicated. A replacement trap and a 5/16" hexdriver or
flathead screwdriver is required. To change the trap:
•
Set the NOA to the Stop mode and wait until the pump is off.
•
Use the hexdriver to loosen the hose clamps on the vacuum tube leading to the
NOA, and the clamp on the clear Tygon tubing leading to the pump. Remove
the trap from the securing clamp on the pump.
•
Remove the old trap from the tubing. A Material Safety Data Sheet is included
with the traps and provides guidelines for proper disposal of the traps. Contact
your safety or environmental health department with any questions on disposal
of the trap.
•
Remove the plastic caps from the ends of the new chemical trap. Hold the trap
vertically and gently tap on the trap to remove any dust. Turn the trap upside
down and repeat the process to remove any dust from the other end of the
trap.
•
Place the hose clamp over the short length of clear Tygon tubing and connect
the elbow end of the trap. Secure the hose clamp with the hexdriver.
•
Place a hose clamp over the black vacuum hose leading to the NOA and connect
the remaining end of the trap to the tubing. Secure the hose clamp with the
hexdriver.
•
Press the trap into the c-clamp on the vacuum pump.
•
Follow the procedures below to reset the timer for the trap.
