Maintenance
2020 Classic

Battery Cleaning
Battery maintenance is an important issue. Maintain a
clean battery top and check terminals and cables for
tightness and cleanliness. A dirty battery will dissipate
its charge through surface contamination. Clean the
battery top with a damp cloth and dry thoroughly.
To ensure maximum battery capacity on the charge
and discharge, the battery terminals and the inside
portion of the cable connector should be scraped
or brushed. The terminals should be tight and free
of corrosion. The battery should be cleaned using
a baking soda and water mix, with a ratio of two
tablespoons of baking soda to a pint of water. The
cable connection should be cleaned and tightened
regularly.
For battery service or replacement, go to a service
station or dealer who sells and services the make of
battery installed in your trailer.
NOTE
Reconnect the battery cables to the correct
battery posts.
Battery Storage
During the winter, the batteries should be removed
from the trailer and stored in a cool, dry place, where
there is no danger of freezing. They should be kept
clean and charged monthly. A battery that is allowed to
completely lose its charge will never regain its original
power or a full charge.
The following recommendations may be helpful if the
battery is to be stored:
• When storing the battery in a vehicle or vessel, it is
not necessary to leave it on charge. Disconnect the
negative battery cable. This will prevent inadvertent
discharging of the battery which may lead to a
complete discharge.
• Fully charge the battery before putting it in storage
and store in a cool place.
• Charge the battery every 30 to 60 days to ensure
maximum battery life.
NOTE
A battery will self-discharge 1-3% per month at 80
degrees.
Water Pump
Water Pump Access Locations
The water pump and strainer are located, depending
on the model, under the refrigerator behind the drawer
or below the wardrobe behind a removable false panel.
Strainer Cleaning
Locate the water pump and housing cap. Turn housing
cap counterclockwise to remove cap and carefully pull
out strainer. Clean strainer in small bucket of clean
water or under running water. If necessary, clean
strainer in a detergent solution. If the detergent solution
is used, rinse thoroughly. Install strainer and housing
cap, being careful not to damage housing cap seal.
Fresh Water Tanks and Draining
Drain Valves
The fresh water line drain valves are located on the
exterior of the trailer for easier access. Between the
tires you will see a galvanized steel box that is a few
inches lower than the trailer frame. The line drains will
be the two brass petcocks extending from the end of
the pan. The white plastic petcock you will see is to
drain the water tank. A second cold water low point
valve is located in the outside utility compartment
between the city water fill and black tank flush.
