Connect Static Mixers, Gun, and
Hoses
1. Connect the outlet of the two primary static mixer
tubes (AW) to the gun and hose assembly (ZU).
2. Check that all connections are tight.
Add Heating Fluid to Heated
Hoppers
1. Use a 50/50 mixture of water and ethylene glycol
(engine coolant) for heating fluid in the outer cavity
of the hopper. Approximately 12 gallons (45 liters) of
heating fluid is needed for each hopper.
NOTE: The ethylene glycol mixture provides the fastest
heat-up time and prevention of algae build-up
regardless of ambient temperature. Oil can be used but
heat-up time will increase and the hopper level needs to
be lower to allow for thermal expansion.
2. Remove fill port cap (ET) and pour heating fluid in
the outer cavity through the fill port (EK).
NOTICE
To prevent creating a flare on the mixer tube, do not
use a union swivel end on the mix tube inlet.

Other glycols (RV/Marine Antifreeze) are not
recommended for use as a heating fluid. These
materials are not rated for higher temperatures and
could cause damage to the immersion heaters.
