- Fresh water tank (12). As an optional extra, the CABIN 400's water reservoir can
be automatically replenished from the vehicle's fresh water system via a
solenoid valve. This is standard supply for campers and an optional extra for
caravans.
- The extra supply consists of a feed hose (13), a second float switch (11), a
suitably modified circuit board in connection box (5), a solenoid valve and all
the fasteners, etc, that are needed
.
• Control system
- Low voltage control cable (8) between the OXYZONE and the float switch and
pump(s).
- Connection box (5), float switch, water pump and solenoid valve (optional). A
fuse for the 12 V control circuit is fitted in the connection box.
- Float switch in the water reservoir (10) signals when the water level is too low.
- Optional: 2. float switch (11), which switches off the automatic water feed from
the vehicle fresh water tank (12).
2.2 Function
To get the best out of your CABIN 400, it is important that you have a thorough
understanding of the unit's function. We therefore recommend that you carefully read
the following.
Ventilation and cooling
The CABIN 400 can:
• ventilate without cooling
• ventilate while simultaneously cooling
When ventilating, the air inside the caravan/camper is refreshed. When the cooling
function is activated the warm air inside the caravan is replaced by cooled air drawn
from the outside.
Cooling
The unit cools by withdrawing the heat energy required for the evaporation of the
water from the air stream. As the water evaporates, heat energy is withdrawn on the
secondary side of the OXYCELL (heat exchanger). This cools the primary side of the
OXYCELL. The warm air that is drawn in from outside is then cooled in the OXYCELL
before being blown into the camper / caravan.
For a detailed functional description, see "Functional principles of the OXYCELL when
cooling" on page 25 .
The relationship between humidity and cooling capacity
The drier the outside air , the more moisture can be absorbed and the greater the
cooling effect.
The way the weather affects the performance (cooling capacity) of the CABIN 400 is
governed by the laws of physics regarding the ability of air to absorb moisture at
different temperatures. Cooling performance will be greater at higher temperatures
and low humidity than at low temperatures and higher
humidity.
