11. Install one flat washer on outside of spring
12. Compress spring and slide actuator rod onto the
pin
13. Install one flat washer on outside of actuator rod
14. Insert cotter pin in hole of pin.
•
Ensure release cable is free and not binding when
cotter pin is installed. Test actuator to ensure cor-
rect operation and release cable does not bind or
interfere with butterfly valve wheel, and butterfly
valve moves to the completely closed position.
15. Return stand tank to normal service.
COLD WEATHER STORAGE
Ice will cause serious damage to the fill pipe and fill
pipe valves if water is allowed to freeze in the tank or
water piping. Ensure all water is drained from the unit
when the temperatures are expected to fall below
freezing for any period of time.
1. Ensure that the unit is stable and is positioned on
level ground. Do not lower the tank.
Empty tank of water prior to lowering. Never
move a tank containing water.
2. Shut-off all water fill sources (hydrant or pump) to
the fill pipes.
3. Open discharge BFV and drain water from the
tank. Be careful not to drain the water so quickly
that it will erode the ground beneath the frame.
4. Use the hydraulic controls to lower the frame to
the ground (as described previously in
“Lowering” procedures).
Keep feet from under the frame or personal injury
could occur. Remove hoses or tools from under
frame before lowering tank.
Extension of the front and rear hydraulic
cylinders are controlled by separate valves. To
avoid damage when raising or lowering the tank,
adjust hydraulic cylinders to keep tank level at all
times.
5. Disconnect and drain fill source hosing.
6. Open fill pipe valves. In order to fully drain the
7. fill pipe, the pipe plug (shown in the Section 8
Illustrated Parts Breakdowns) must be
unscrewed.
8. Check to ensure that all water has drained from
tank, fill pipes, and valves.
REACTIVATING UNIT
1. Re-install pipe plug into fill pipe valve.
2. Close discharge BFV and fill pipe valves.
3. Set up the tank in accordance with “Set Up”
operating procedures.
