Block Filter:
Improve water quality
by reducing objectionable organic
chemicals, chlorine, tastes and odors.
Recommended change interval
depending on usage and incoming
water quality. Prior to disinfecting the
water system with a chlorine bleach
solution, remove the
fi
lter elements and
reassemble the
fi
lter bowls without the
elements. Use the following procedure to
remove or change the
fi
lter elements.
Removing the Filter:
Turn
OFF
the water
supply and the water pump.
Open the hot and cold faucets at
the service center shower to
bleed off pressure.
Unscrew the
fi
lter bowl
from the
fi
lter head using the
water
fi
lter removal wrench.
Remove the old element and
empty any remaining water
in the bowl.
Installation:
Place the elements in the bowls,
observing primary and secondary
fi
lter
locations.
Screw the bowls onto the
fi
lter heads and
tighten by hand.
Turn ON the water pump or city water.
Close the outside shower faucet after all
the air is purged from the
fi
lter assembly.
Check for leaks.
WATER SYSTEMS
Troubleshooting
If the water pump cycles after closing the
faucets, drain valves and inlet valves, a leak
may be present. At this time check for leaks
around
fi
ttings, valves,
fi
lters, and connections
of the hot and cold water system. If problems
continue take the motorhome to an authorized
dealer for repairs.
Disinfecting Fresh Water
Disinfecting the water system with household
bleach (superchlorination) protects against
bacteriological or viral contamination from
common water sources.
Disinfect the fresh water system:
If the motorhome is new.
If the motorhome has been in storage.
Every three months during use.
To Disinfect the Water System:
1. Remove water
fi
lter elements and re-
install the
fi
lter housings.
2. Drain the fresh water tank. Close drain
when empty.
3. Prepare a disinfecting solution using
one of the following methods:
Combine one gallon of water and ¼
cup of household bleach. Use 1 gallon
of this solution for every 15 gallons of
tank capacity.
Multiply tank capacity (in gallons) by
0.13. The result is the amount (in ounces)
of household bleach to pour into fresh
water tank. These methods will yield a
50 PPM (parts per million) disinfecting
solution in the water system that will act
as a quick-kill dosage for harmful bacteria,
viruses and slime-forming organisms.
Concentrations higher than 50 PPM may
damage the water lines and/or tanks.
4. Pour the solution into the gravity
fi
ll
opening.
5. Top off tank with fresh water.
6. Turn
ON
the water pump in the
motorhome.
7. Open each faucet and run water until
you smell a distinct bleach odor.
8. Turn
OFF
all faucets and allow the
system to stand for four hours.
9. Drain the fresh water tank of the
mixed solution.
