Vent Fitting Assembly
1. Remove the dust cap and clamp the coupling half in place.
2. Install the vent pipe; hand-tighten only.
Some tank models are equipped with cam lock lever couplings whose design is
different from the design of other tank models.
3. Install the mushroom type vent relief cap, hand-tighten only. Make sure the flap moves freely. The
flap must be in the closed position.
Only two operator controls are utilized on the water tanks. They are the gate or ball valve to control the
water flow during fill/discharge and the drain ball valve to control draining.
