2) Mix 50% ethylene glycol with 50% distilled water in a clean container. Refer to Table 1 or glycol
manufacturer’s literature for freezing points.

3) Remove pressure cap on top of reservoir. Pour mixture in until level reaches height shown in
Figure 3. Filling reservoir above this level will not cause any damage but coolant may be
expelled from pressure relief port below cap due to normal thermal expansion of coolant.
4) Connect 24 V to controller.
• At the Display check for any ALARMS
• Press the POWER ON/OFF button
• The flywheel will start to spin and the glycol pump will start.
• Recheck glycol level with fluid circulating in coolant circuit. Sight down inside reservoir and
check that coolant level is above upper port on reservoir as shown in Figure 3. Replace cap.
• After several minutes of running, press POWER ON/OFF button to turn power off to
the flywheel and glycol pump. The glycol pump will stop and the flywheel will coast to a
stop.
5) The cooling system is self-purging. If small amounts of air are in the system, they will most likely
be dislodged during the first sea trial. Recheck level after sea trial and add fluid if required.
