Operation Instructions
4-3
9. Install the hitch pins into all six (6) frame legs.
Install all the hitch pins and be sure that they
extend completely through both sides of each
leg. Use the hitch pin installation tool if necessary
to reach the holes.
Failure to install hitch pins in all six (6) frame legs
may result in damage to the tower.
10. Use the hydraulic controls to lower tank until it
rests upon the hitch pins. Turn off the power unit.
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 the tank level at all
times.
11. Connect the water supply to the tank. Check the
ball float ball and float valve for proper operation.
12. Use tie downs to prevent wind damage to the
tower tank in high wind conditions. Tie-down
locations and details are given in “Figure 4-1: Tie-
downs” on page 4-4.
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 fill
pipe, the pipe plug (shown in the Section 8
Illustrated Parts Breakdowns) must be
unscrewed.
7. 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.
