DRAINING THE TANK
WARNING
The tank can only be emptied by gravity or suction pump. Use of air pressure to
unload the tank is not authorized as it may cause the tank to burst under
pressure and cause injury to personnel.
Draining by Gravity
1. The end of the tank opposite the valve must be 8 to 10 inches higher than the valve end of the tank to
thoroughly complete draining of the tank. The valve corner should be the lowest level of the tank. Use
the grade elevation or portable ramps under the appropriate trailer wheels.
2. Connect one end of the 4-inch diameter hose assembly to the tank filler/discharge valve.
3. Connect the other end of the hose to the hose or container requiring the potable water.
4. Close the tank pressure gage valve.
5. Open the filler/discharge valve on the tank to start the flow.
6. After the operation is complete, close the filler/discharge valve on the end of the tank.
Draining by Pump
1. Connect one end of the 4-inch diameter hose assembly to the tank filler/discharge valve.
2. Connect the other end of the hose to the hose from the pump.
3. Close the tank pressure gage valve.
4. Open the tank filler/discharge valve.
5. Start the pump. Draining rate is not a factor in tank operations.
6. After operation is complete, close the tank filler/discharge valve.
7. Close the valve on the pump.
8. Disconnect the 4-inch diameter hose assembly from the hose container or vacuum pump, depending
on applicability.
9. Disconnect the hose from the tank filler/discharge valve.
REPACKING
CAUTION
Make sure the tank is completely dry before folding. Water will create mildew,
decreasing the life of the tank if it is not completely dry.
1. Remove the pressure gage (1).
2. Disconnect hold-down kit ratchets (2) and remove. Hang loose ends of the belts over the sides of the
trailer.
