left-hand side of the rear of the unit and plug into a
live outlet. Turn on power entry module switch.

5.
Rinse one complete reservoir volume of water through
the cartridges to drain.
6.
Remove a new 0.2 micron filter and bell assembly
from its bag and insert it into the Luer fitting. Gently
turn it clockwise until it is fully seated in the Luer fit-
ting.
7.
Refill the reservoir with pretreated water.

NOTE
The upper end cap is the one with the right-an-
gle turn and the two flanges. The lower end cap
extends straight out from the cartridge. (See
Figure 3.)
NOTE
The two flanges on the end cap should be able
to slide down on each side of the keyway wall.
NOTE
Cartridge rinse up procedure must be followed
after each cartridge and/or filter replacement.
NOTE
In the event that you overfill the feedwater res-
ervoir, allow the excess water to drain from the
reservoir through the overflow drain tubing be-
fore replacing the Ventgard cap. This will pre-
vent wetting the filter element.
