Swift MONZA CAMPERVAN Owner's Manual page 45

The water systems, and in particular storage
tanks, in campervans are susceptible to
contamination by bacteria if care is not taken
with their use and cleaning. The symptoms
caused by bacterial contamination are not purely
limited to gastro-intestinal diseases, but may
also manifest themselves as ear, nose, throat,
eye or skin infections. It is therefore important
that you carry out the following procedure prior
to using the campervan each time, even if you
boil or filter all water you use for drinking.

For the fresh tank:
1. Drain down the system (open all taps to
allow air in, enabling the system to drain
quickly). Removing the underside sump
bolts is advisable to remove all water.
2. Remove any aftermarket filters fitted, and
replace with a short length of hose or empty
filter cartridge (this will ensure the filter is
not affected by the disinfectant/ sterilant
solution).
3. Fill the water system with a disinfectant/
sterilant solution (check that the solution at
full strength appears at all taps/showers).
Allow to stand for the recommended period
of time.
4. Drain the system completely.
5. Thoroughly clean the outside of all taps/
connectors with a cloth soaked in the
disinfectant/sterilant.
6. Flush the system through with clean drinking
water until no traces of disinfectant/sterilant
can be detected at any tap.
Suitable sterilising chemicals are available
from your campervan dealer, accessory
shop, chemist or home-brew shops. It is not,
however, recommended to use bleach or sodium
metabisulphite.
Sterilising
Do not use products that contain aggressive
agents for sterlising the water system. Always
use products designed for stainless steel tanks
available from your campervan dealer.
