Changing between Ratios & Materials:
1. Properly flush and clean the fixed 100cc Fluid Section of the existing material. Using
solvent purge the fixed 100cc fluid section and hoses of the material being removed.
Purge the Solvent from the system (pump and hoses) and clean or replace any
items that will contaminate the new material.
2. Secondary Pump - If the system is using the 20cc, 50cc or another 100cc fluid
section to meter the second material (hardener, activator or B-component) also flush
and clean this pump. As with the main component material purge the secondary
pump and hose with solvent or cleaning agent.
3. When using the Catalyst Pump (5cc pump) with MEKP catalyst it will not necessary
to purge out the catalyst unless the catalyst and pump will not be used for more than
six months. If the catalyst system will sit idle for longer than the expiration date of
the catalyst than drain and pump out the catalyst system. Clean the catalyst jug and
feed tube with warm water, remove and clean any filters.
4. Disconnect and remove the Secondary pump and replace with the new fluid section.
Set the new pump at the desired ratio on the Ratio Arms and connect to the injection
head using the correct hoses.
5. If necessary reconnect the Interlock Air Signals from the Hardener RAV (1:1) to the
Catalyst CAV (188:1) or the other way around.

configured for CAV (lower
ratio materials) this will
connect to the CAV signal
ports.
