Pressure Accumulator Tank - Holiday Navigator 2003 Owner's Manual

The pressure accumulator tank mounts in the water bay near the water
pump. The pre-charge pressure in the accumulator tank should be checked
monthly.
The Accumulator Features:
1. Smooth flow from the faucets.
2. Reduced water pump cycling.
3. A pre-charged air cushion.
4. Elimination of pulsation and water hammer.
5. Water pressure at faucets.
The accumulator tank has a tire valve that is used to pre-charge the tank
with air pressure. The pre-charge pressure must not exceed the water pump
cut-in pressure, the pressure at which the pump restarts. The water pump has a
cut-in pressure of 40 psi. The pre-charge pressure of the accumulator tank is 18
to 22 psi. To check the air pressure in the accumulator tank the water pump
and city water will need to be off. Open a faucet to relieve the water pressure.
Using a tire air pressure gauge, one that reads low air pressure, check the
accumulator tank pressure monthly. Use a hand-operated pump to add air
pressure to the accumulator tank. The amount of airflow and high-pressure
from a compressed air system can quickly overcharge the tank causing the
internal bladder or tank to rupture.
