Secure arm in place by tightening the
set screw. Note: You will need to adjust arm once
locking mechanism is in place.
Step 4:
Install Locking mechanism onto the
mounting bracket of the EcoMAXX NRV. Note:
Ensure the handle is centered in the locking mech-
anism. If installed incorrectly, handle may rub or
stick preventing the counter weight from locking in
place during an event.
Step 5:
Slide counter weight onto the shaft and
insert safety pin to keep counter weight in place.
Step 6:
Insert bolt and washer to secure the
counterweight onto the shaft.
Step 7:
With safety bolt in place and counter-
weight secured, mount the breaking element to
the counterweight and tighten bolts. Note: Bolts
need to be snug. Do not over tighten, this may
damage the breaking element.
Step 8:
IMPORTANT!! Be sure to remove safe-
ty pin from the counterweight. Failure to do so will
cause the EcoMAXX No Return Valve to not close
fast enough during an event.
