Water Filter (Opt) - Monaco 2002 Diplomat Service Manual

The water pump will not shut-off/runs when the faucet is closed:
• Make sure the fresh water tank fill valve is completely closed.
• Check output side (pressure) plumbing for leaks and inspect for a
leaky toilet or valves.
• Look for loose drive assembly or pump head screws.
• Are the valves or the internal check valve held open by debris or is the
rubber swollen?
The water pump is noisy or rough in operation:
• Check for plumbing which may have vibrated loose.
• Does the mounting surface multiply noise (flexible)?
• Check for mounting feet that are loose or compressed too tight.
• Look for loose pump head to motor screws (three long screws).
• Is the motor with the pump head removed? Is noise coming from the
motor or pump head?
The water pump is rapid cycling:
• Look for restrictive plumbing/flow restrictors in the faucets or shower
heads.
The water filter is located under the
galley sink. It may have been installed
without the cartridge placed in the unit.
The unit's ADC Cartridge can easily be
installed by following the instructions
on the cartridge wrapper. A fresh
replacement cartridge is needed when
the flow of water from the faucet is
restricted. The life of the filter will vary
depending on the condition of the unfil-
tered water and the quantity used.
Each time water passes through the
water filter, dirt particles are trapped and
held in the tiny pores of the micro-pure coating on the
filtering element within the cartridge. As the cartridge actively removes the
impurities from the water its microscopic pores fill up and the amount of water
flowing from the cartridge gradually lessens. When the flow of water from the
water filter becomes too slow for convenience it should be serviced. If the car-
tridge is not changed, the flow will eventually stop entirely. Even if the car-
tridge does not indicate its need to be changed, change it at least once a year
for reliable performance from the purification system.
