Tips And Advice - Polar Electro 520 CTH DB 2020 Instruction Book

As the owner and user of the caravan, there are many things you need to think about. Below is a short compilation
of the most common questions people may have before using the caravan.
Loading the caravan
• To achieve the optimum driving properties, it is
important to distribute the load evenly in the caravan.
Read more about this in the section "Loading the
caravan" on page 14.
Pitching for an extended period
• If you are not going to use the caravan for an extended
period, there are a number of steps you must take before
putting the caravan away. Read more about this in the
section "Pitching for an extended period" on page 18.
Condensation/misting in the caravan
• Condensation can occur if you bring wet clothes,
dogs, etc., into the caravan under certain weather
conditions. Ventilation and heating are an effective
way of combating condensation on the inside of
the windows. Read more about this in the section
"Windows, ventilation" on page 22.
Washing the caravan
• Never use high-pressure wash or solvents/degreasing
agent when washing/cleaning the caravan, as this can
damage the seals around windows, roof hatches, etc.,
with a risk of leaks as a consequence. Read more about
washing in the section "Washing" on page 23.
Ventilation system
• Fresh air intakes and vents may not be blocked under
any circumstances.
• Do not perform any modifications or actions in the
ventilation system.
• When you have pitched the caravan, make sure that
the fresh air intakes are completely free of snow and
anything else that could obstruct circulation. When
the caravan is used, dirt and dust collect in the ven-
tilation openings. These must therefore be cleaned
at least once a year in order for the ventilation to
function properly.
Read more about the ventilation system in the section
"Ventilation system" on page 23.
Snow on the roof
• In order for the ventilation in the caravan to work,
it is important for the vents and roof hatches to be
free of snow and ice.
• It is important for the roof to be regularly cleared
of snow to ensure that the weight on the roof is not
excessive, causing the roof to bend inwards. Ice can
also form on the roof when the caravan is heated
up, which can also result in excessive weight on the
roof.
• Snow can be removed from the roof with a spade or
broom. When using a spade, take care to ensure that
you do not damage the roof. It is best not to clear the
snow all the way down to the roof panel.
• Never try to knock ice away with a spade or broom.
This can cause dents in the panels.
• In unfavourable weather conditions in the winter,

there is a risk of snow penetrating through the roof
hatch's ventilation. You must therefore remember
to protect the caravan's fixtures and fittings and its
upholstery, particularly when the caravan is due to
be pitched for an extended period.
The LPG box is equipped with a holder for the box
lid. It is important to use this holder in the right way.
Read more about this holder in the section "LPG
box" on page 25.
In caravans with tent service it is possible to connect
the caravan to cable TV via the TV aerial input in
the tent service output. See the section "Connecting
cable TV" on page 40.
The LPG bottle must be switched off before driving
with the caravan. You are not allowed to drive with
the LPG apparatus lit.
Test the LPG system with the leak indicator every time
it is to be used and whenever you change the bottle. Any
faults must be rectified by an expert. Read more about the
LPG system in the section "LPG system" on page 41.
If you want to leave the caravan for a while, and want
somebody else to start up the heating by connecting
the caravan to 230 V, the built-in "winter connection
function" can be used. Read more about this in the
section "Winter connection function" on page 47.
If the caravan is to be left standing for an extended
period, or if the temperature while it is pitched will be
below 0°C and the caravan is to be left unheated, the
water system and the drainage system must be emptied.
Read more about this in the sections "Emptying the
fresh water" page 52 and "Emptying the drainage
system" page 55.
After the water and drainage system has been used
for a period of time, it may be time to clean the water
and drainage tank.
A decalcification of the water system should be made
in connection with cleaning of the water system.
Read more about this in the sections "Cleaning
the water tank" on page 53, "Decalcification of
the water system" on page 53 and "Cleaning the
drainage tank" on page 55.
To facilitate servicing and moisture testing, remove
all cushions and personal items from the caravan.
