Excella II, International and Argosy models and
in the front roadside corner on Caravelle and
Minuet models, and fill with a hose or a bucket.
Close and lock .the spout and the water system
is ready for use.
To clean the tank, pour some bicarbonate of
soda into the filler spout with several gallons of
water and allow to stand for a minimum of four
hours. Then flush the tank out by opening a
faucet, allowing the water pump to drain the
system. Then refill with fresh drinking water. If
the water tank must be cleaned further, the
following procedure is recommended.
1 . Prepare a sodium hypochlorite solut~on
using potable water and household bleach
(5 1/4 to 6%) in the ratio of
1/4
CUP
of bleach
to 1 gallon of water. (Common household
bleaches are Purex and Clorox.)
2. Pour 1 gallon of hypochlorite solution for
each 1 5 gallons of capacity into the empty
water tank.
3 . Add enough potable water to completely
fill the water system.
4. Allow closed system to stand for three
hours.
5. Drain the hypochlorite solution from the
system and refill with potable water.
6. Excessive hypochlorite taste or odor
remaining in the water system is removed
by rinsing the system with a vinegar
solution mixed in the ratio of 1 quart of
vinegar to 5 gallons of water.
7. Drain the system and flush with fresh
drinking water.
8. Drain the system and refill with fresh
drinking water.
The optional Everpure QC-2 Water Filter is
located under the galley sink. It will remove
even very fine dirt and colloidal matter, and
eliminates most chlorine, phenol and similar
distasteful odors and tastes, while delivering
sparkling taste-free water for drinking and
cooking. The filter is connected to the cold
water galley drinking faucet only. The filter will
also remove iron and sulphur provided the
water supply is chlorinated. Super-chlorination
will precipitate the iron and sulphur which will
then be removed by the QC-2 Filter. To purify
any questionable water, fill the Everpure
Chlorine Disinfectant Dispenser with liquid
bleach and add 1 / 6 ounce (one teaspoonful)
per 10 gallons of water in the water tank. The
