Potlife Volume
Set to the total volume of mixed fluid in the system. This
includes the mix manifold, integrator, static mixer, fluid
hose, and applicator. The ProMix™ II controller uses
this volume and the Potlife Time to determine if the
mixed material has been in the system longer than the
potlife time.
The potlife volume is set in either ounces or cc based on
units selected in Advanced Screen 1. Set from 0-999 cc
or 0-33 ounces. If you change the units, this value
updates to the new units. Default is 350 cc (12 oz.).
The volume of the ProMix™ II mix manifold, integrator,
and static mixer is 100 cc. To determine the volume of
your fluid hose to the gun, use the following information.

Hose Volume
English Units
Hose volume = 154.4 x (ID)
2
(in.) x Length (ft.)
Metric Units
Hose volume = 0.785 x (ID)
2
(mm) x Length (m)
Potlife Volume
Potlife volume = 100 cc + Hose Volume
Example:
If you are using a 25 ft., 1/4 in. ID fluid hose:
Hose volume = 154.4 x (0.25 in.)
2
x 25 ft. = 241 cc
Potlife volume = 100 cc + 241 cc = 341 cc
