Pressure Accumulator Tank; Water Filters - Holiday Rambler Imperial 2008 Owner's Manual

WATER SYSTEMS — 6
Water pump will not prime or sputters
(No discharge/motor runs):
Is the pump inlet strainer clogged with
debris?
Is there water in the tank or has air
collected in the water heater?
Is the inlet tubing and plumbing
sucking in air at plumbing connections
(vacuum leak)?
Check for proper voltage with the
pump operating.
Check the pump housing for cracks or
loose drive assembly screws.
Water pump will not shut-off or continues
to run when the faucet is closed:
Check to see if the fresh water/tank fi ll
valve is completely closed.
Check the output (pressure) side
plumbing for leaks and inspect for a
leaky toilet or valves.
Look for a loose drive assembly or pump
head screws.
Water pump is noisy or rough in operation:
Check for plumbing that may have
vibrated loose.
Does the mounting surface multiply
noise (fl exible)?
Check for mounting feet that are loose or
compressed too tight.
Look for loose pump head to motor
screws.
Water pump is rapid cycling:
Look for restrictive water fl ow in the
faucets or shower heads.

PRESSURE ACCUMULATOR TANK

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 tank can be accessed
behind a sliding panel in the compartment next
to the water service bay.
Valve
Cap
Remove tank valve cap to check air
pressure
Accumulator Features:
1. Smooth fl ow from the faucets.
2. Reduced water pump cycling.
3. A pre-charged air cushion.
4. Elimination of pulsation and water
hammer.
5. Sustained water pressure at faucets
before pump cycles on.
The accumulator tank includes a valve
designed to pre-charge the tank with air
pressure. Pre-charge pressure must not exceed
water pump cut-in pressure, the pressure at
which the pump restarts.

The water pump has a cut-in pressure of 40
psi. Pre-charge pressure of the accumulator
tank is 18 to 22 psi. To check 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. Check
the accumulator tank pressure monthly using
a tire air pressure gauge (one that reads low
air pressure). Use a hand-operated pump to
add air pressure to the accumulator tank only
when needed. The amount of airfl ow and
high-pressure from a compressed air system
can quickly overcharge the tank, causing the
internal bladder or tank to rupture.

WATER FILTERS

A whole house water fi lter system consisting
040494e of a primary and secondary fi lter is used to
provide clean water. Water supplied by shore
service or the fresh water holding tank is
fi ltered to all faucets, shower and any standard
or optional appliances. The primary mesh
fi lter removes dirt and small particles. The
secondary carbon block fi lter helps to further
purify by removing foul taste and some harmful
organisms.
First Stage - Five Micron Sediment
Filter: For reduction of suspended
solids, dirt and rust. Life expectancy
varies with incoming water condition.
Recommended change interval
depending on usage and incoming water
quality.
