Owners/Users
To get the most out the CABIN 400, you need to have a thorough understanding of
how the unit functions. See "System construction and function" on page 5.
For daily use, see "Application and use" on page 8.
If you do not intend to use the CABIN 400 for a period of four weeks or more, the
system must be put into storage mode in order to prevent sediment and contaminant
build-up in the water reservoir and the OXYCELL (heat exchangers) in the roof unit.
For instructions, see: "Storage mode" on page 22.
The CABIN 400 is a robust system. Cleaning the inlet screen, the water reservoir and
the exhaust filter is the only maintenance required. (see "Maintenance" on page 18)
If the system is inadvertently switched on or if problems arise, see "Troubleshooting"
on page 26.
Installation

Figure 2.1 Schematic diagram showing the installed CABIN 400 system. The arrow indicates the
direction of vehicle movement.
• The roof unit (1): contains the OXYCELL (heat exchanger) and the fan.
• Inside the vehicle:
- The OXYZONE (2) allows adjustment of the horizontal and vertical air streams.
The operator panel is fitted to the OXYZONE.
- The water reservoir (3) for the water feed to and return from the roof unit
(OXYCELL), complete with screw-on cap (4) and connection box (5).
- Water feed hose (6), water return hose (7), reservoir drain hose (14), water
reservoir overflow (9).
- There are two pumps in the water reservoir. The feed pump delivers water to the
sprinkler in the OXYCELL (heat exchanger) in the roof unit. The return pump
returns excess water to the water reservoir.

- 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.
System construction and function

00010605 B 7
In very damp weather, humidity will be extremely high and ambient air will be less
able to absorb extra moisture. For maximum CABIN 400 performance in these
weather conditions, the exhaust ducts of the OXYZONE should be opened fully and
the screen slide fully shut. The air stream will be clearly perceptible.
Water consumption
When the cooling mode is activated, water is pumped from the reservoir for a few
seconds at intervals of a number of minutes. The water is fed through the feed hose
to a sprinkler in the roof unit. The sprinkler moistens the heat exchanger. Any water
that is not immediately used by the heat exchanger returns to the reservoir through
the return hose. Evaporated water is exhausted to the outside via the roof, together
with the moist air (on the cooler side).
Depending on usage (cooling setting and the weather) the water reservoir will
gradually empty and will at some point need refilling.
Note
In extremely dry and/or warm weather (above 35oC), we recommend
increasing the frequency with which the heat exchanger is moistened.
See "Extra water feed for use in extremely dry and/or hot weather." on
page 12.
Note
As an option, the vehicle fresh water tank can be used to automatically
replenish the water reservoir. The parts required for this may only be
fitted by the dealer.
Advantages of the CABIN 400
• The construction and function of the CABIN 400 offer significant advantages in
comparison to typical air conditioning systems:
• Energy consumption is low: approx. 15% of the energy consumption of typical air
conditioning systems.
• Noise levels are low both inside and outside the caravan/camper. This keeps
nuisance to a minimum for both the user and the surrounding environment.
• The air is cooled very quickly; it is even possible to leave a window or door open
in the caravan/camper.
• The system is compact, light and does require much maintenance.
• The system is environmentally friendly:
- environmentally harmful cooling gases are not used;
- all the materials used in the manufacture of the CABIN 400 can be recycled.

3 APPLICATION AND USE
3.1 Prior to commissioning
Water reservoir
Ensure there is enough water in the water reservoir. Use water of the same purity as
dr inking water . It is re comm ende d that an anti-algae additive is used. For instructions
about using additives see "Required water purity and the use of additives" on page 13.
For instructions on filling see "Filling the water reservoir" on page 14.
Note
The water reservoir has been carefully positioned by the installer. All
hoses have been installed carefully and without kinks. Do not tamper
with the installation in order to avoid catching or restricting any of the
hoses.
Power supply at the final destination
When the final destination is reached, the CABIN 400 receives its electrical supply via
the 230 Volt mains connection.
Power supply when travelling
When the CABIN 400 is used during the journey to the final destination, the electrical
supply is provided by the 12 Volt battery via a static converter. Even though the unit
consumes very little power, it should be noted that it can flatten the battery. As
standard, the Cabin 400 is fitted with a static converter with an automatic switch-in
function. Should the external 230 V supply be interrupted, the static converter will
automatically switch to battery power.
Application and use
17
00010605 B 9
Note
When the vehicle is not in use, the static converter should be switched
of at the main isolator. Otherwise the unit will continue to draw a small
amount of power, which could flatten the batteries.
Ventilation and cooling
The operator panel on the OXYZONE is used to set the desired level of ventilation or
cooling (see "Adjusting ventilation settings" on page 11 and "Adjusting cooling
settings" on page 11). Air flow is regulated by adjusting the slides in the screen frame
and the exhaust vents of the OXYZONE.
