Check to see that the tank is properly installed. The trailer bed
should be level to prevent the tank from rolling.
Tighten all the cap screws to 70 ± 5 ft. lbs. torque on the end
clamp bolts.
The rubber in new tank will "cold flow" under the
pressure and the torque will drop. Tanks should be re-torqued
periodically until the rubber has set and the torque doesn’t drop
appreciably.
If leakage is noted at the fittings or if the tank is
subjected to hard usage, cap screws should be re-tightened
periodically.
Attach the pressure gage to the filler/discharge valve as shown in
Fig. 2-7.
Then open the pressure gage valve. (3, Fig. 2-7).
Before
NOTE
Before using the tank for the first time or prolonged
storage, flush the tank with 100 to 300 gallons of clean
disinfectant and water solution. The solution consists of
1/2 gallon of commercial bleach mixed in 250 gallons of
fresh water.
Surge the cleansing solution by walking back
and forth on the tank or by rocking the truck with abrupt
starts and stops.
The resultant surge will clean the
collapsed tank without exposing its interior to contaminants’
or foreign objects.
Rinse tank with 250 gallons water to remove bleach taste.
When the cleaning is complete, close t h e
