1 INTRODUCTION

1.1 Preliminary note

Your caravan / camper is equipped with an extremely innovative and user-friendly OXYCOM ventilation and cooling system: the CABIN 400

We recommend you read this operating manual carefully in order to ensure proper maintenance and correct use. Keep this manual in a safe place so that you can refer to it at a later date.

Note

You can download the latest version of this manual from: www.oxycom.com

1.2 User groups

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

The CABIN 400 may not be installed by anyone other than your dealer. He has the best knowledge of your vehicle and will adhere to all the relevant regulations and safety standards when installing the unit.

Introduction

00010605 B 4

System construction and function

00010605 B 6

- 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

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.

Figure 3.1 A: OXYZONE base, B: OXYZONE extension (Option), C: end cover with adjustable

exhaust vents, D: screen frame, E: operator panel

Application and use

00010605 B 10

First commissioning of the CABIN 400

Your dealer has installed the CABIN 400 with the greatest possible care. However it is recommended that you check that the water hoses running down to the water reservoir are free of kinks. (see "Figure 3.2").

Figure 3.2 The water hose must be carefully positioned.

If the water hoses become kinked, water that has not evaporated will not return properly to the water reservoir and could overflow out of the roof unit and drain off over the roof. This will lead to higher water consumption.

3.2 Switching on the CABIN 400

Operator panel

Figure 3.3 CABIN 400 operator panel

Note

An audible tone will sound each time an adjustment is made, unless this function has been switched off.

Switching on

When the CABIN 400 is switched off, none of the LEDs are lit or flash.

Press the On/Off switch . The CABIN 400 will automatically return to the settings that had been selected before it was switched off, even if the cooling function was

activated. (If the CABIN 400 has been switched off for a long period, the cooling initialisation program will start up first.)

Note

As soon as the CABIN 400 is switched on, the function that was in use when the unit was switched off will be reactivated.

3.3 Adjusting ventilation settings

Press the fan switch . Each time the switch is pressed, the next ventilation setting is activated:

Figure 3.4 Ventilation settings 1 to 4 are activated sequentially.

3.4 Adjusting cooling settings

The CABIN 400 must be switched on and the desired ventilation setting must be activated.

1. Press the cooling switch .

Cooling starts. The fan will temporarily revert to level 1 so that the OXYCELL can be properly moistened. The LEDs L1, L2, L3, L4 on the operator panel will start to flash, when the cooling function is first switched on. Water is pumped up from the water reservoir to the sprinkler in the roof unit in order to moisten the OXYCELL (heat exchanger). The moistening process when cooling first starts lasts about 3 minutes. The fan operates at level 1 during this period.

2. The cooler will revert to the ventilation setting that had been selected before the cooling function was activated. It is now possible to select any one of the ventilation settings as required, by pressing the fan switch .

Figure 3.5 Cooling settings 1 to 4 are activated sequentially.

Application and use

00010605 B 12

Note

The fan will only provide cooled air when LED Lc is lit.

3.5 Extra water feed for use in extremely dry and/ or hot weather.

When the outside air is extremely dry and/or hot (e.g. in a desert climate), the water in the heat exchanger will evaporate more quickly. The period of time during which the OXYCELL is moistened must be reduced if the "extra water feed" setting has been activated.

To do so simultaneously press the ON/OFF switch and the fan-switch for 4 seconds. (A tone confirms that the setting has been successfully activated)

Note

When the CABIN 400 is next turned off, the water feed setting reverts to normal. The OXYCELL will then be moistened in the normal way.

3.6 Controlling the air stream

The following components make it possible to control the air stream though the OXYZONE:

- The ventilation setting, see "Adjusting ventilation settings" on page 11

- The screen setting (vertical air stream)

- The position of the exhaust vents (horizontal air stream)

Figure 3.6 The air stream can be controlled from the operator panel (B) on the OXYZONE (A). The

air stream can be controlled by adjusting the screen (D) and the exhaust vents (C).

Application and use

00010605 B 13

Note

The most comfortable level of cooling is achieved when the screen is fully open and the exhaust vents are closed.

The highest ventilation level (greatest air displacement) is achieved by fully opening the exhaust vents and closing the screen.

Fine adjustment of the air stream

Fine adjustment of the air stream can be achieved by adjusting the screen in combination with the exhaust vents. If, for example, a horizontal air stream is not required, the exhaust vents should be shut. If only a horizontal air stream is required, the screen should be closed and the exhaust vents should be opened. At night, it is best to adjust the fan or the cooling to level 1.

However, the user is of course free to select any of the possible permutations.

Note

We recommend opening a window or skylight at the front and back of the sleeping area to maintain a flow of air. The flow of cooled air will descend towards the floor. If two skylights or windows are open, warmer air will be forced out of the vehicle by the incoming flow of cooled air. This ensures optimum air movement.

The window or skylight that is open should be as far away as possible from the roof unit's exhaust vents (in order to prevent ineffective air movement).

If all the windows and doors are closed, warmer air will be forced out of the camper's/caravan's ventilation grilles. This may be insufficient to allow optimum ventilation and/or cooling.

3.7 Using the cooling function to the best effect

It is better to take measures to prevent the inside of the vehicle warming up, rather than allowing it to heat up during the day and then turning on the cooling. It is therefore recommended that you turn on the CABIN 400 as early as possible, e.g. when you leave the camper / caravan in the morning.

If the vehicle is fitted with roller blinds, we recommend you shut them (when not in the vehicle). Your accessory supplier stocks standard reflective materials, which can be applied to the outside face of large glazed surfaces. Windows will otherwise allow excessive amounts of heat to penetrate to the interior.

3.8 Required water purity and the use of additives

Drinking water must be used for the cooling system in order to avoid the build up of impurities.

Using an antibacterial additive (additive 2)

Before using the CABIN 400 for the first time, or prior to starting the unit up after a long period of disuse, we recommend adding an antibacterial additive (additive 2) to the water as indicated on the packet.

Application and use

00010605 B 14

Note

Use only pure drinking water. Do not use water that appears to contain sediment or water from pools or lakes.

If in doubt, request information from the local water authority or the manager of the camping site. See "Water quality" on page 24 )

Note

The CABIN 400 has been constructed in such a way that no health risks will arise if contaminated water is inadvertently used. As the system does not produce a mist of fine droplets, there is no risk of infection by legionnaire's disease.

3.9 Filling the water reservoir

Warning signals indicating an insufficient water level

The cooling function requires water. Water is not required when the unit is used for ventilation purposes. The water reservoir must be replenished dependent on weather conditions and use (this is partly influenced by the fan settings and the number of operating hours).

Note

Insufficient water will not however cause damage to the CABIN 400.

Warning signal: if there is insufficient water in the vehicle fresh water tank when the unit is used for cooling, an audible tone will sound at the operator panel and LED L1 will flash (only applies to systems where the reservoir is replenished automatically).

Once the fresh water tank has been refilled, the warning indicator can be turned off by pressing the button. The system will then replenish the CABIN 400 water reservoir.

Refilling the reservoir (systems without automatic replenishment)

Note

It is not necessary to switch off the CABIN 400 when refilling the water reservoir.

LED1 will flash when it is necessary to refill the water reservoir.

1. Remove the cap from the water reservoir.

2. Refill the reservoir with drinking water. (see "Required water

purity and the use of additives" on page 13).

3. Replace the cap.

The system will automatically return to normal operation.

3.10 Draining the water reservoir

We recommend that you drain the water reservoir and refill it with fresh water at least once a week. As the unit is used, more and more sediment will build up in the bottom

Application and use

00010605 B 15

of the reservoir. If the reservoir is only refilled and not fully drained, sediment will build up much faster in the system.

Warning signal: after a set number of operating hours, the system indicates when the water reservoir needs draining (LED 2 and LED 4 will flash). The system will however continue to function.

Proceed as follows to fully drain and replace the water in the water reservoir:

Step 1: Draining the water reservoir and checking the filter

1. Turn off the cooling function by pressing the button.

2. Remove the cap (including hose and cable) from the water reservoir.

3. Check that the water pump filter is clean.

If the filter looks dirty, remove and clean it. See "Cleaning the water pump filter" on page 21.

Note

After cleaning, do not forget to refit the filter. The system will otherwise become clogged, which may cause damage to the OXYCELL.

4. Draining water off via the drain cock (open the drain cock, the position of the drain

cock depends on the type of vehicle).

5. Pour a little drinking water into the reservoir in order to wash away any sediment

(loosen the strap and shake the reservoir to and fro).

6. Close the drain cock.

Step 2: Filling the water reservoir

1. Replenish the reservoir with drinking water by pressing “reset” or by pouring water

into the reservoir. (see "Required water purity and the use of additives" on page

13).

2. Add additive 1 to the water as indicated on the packet.

Note

Additive 1 improves the distribution of the water in the elements of the OXYCELL heat exchanger.

3. If the water pump filter has been cleaned: ensure that the filter has been

correctly refitted to the pump.

4. Refit the cap (including hose and cable).

5. Turn off the "insufficient water in the water reservoir" signal (if

active)

6. (see illustration on the right: LED1 flashes) or the "drain and

refill the water reservoir" signal (see the illustration below: LED4 flashes), by pressing the button.

The CABIN 400 is now ready for use again.

Application and use

00010605 B 16

3.11 Turning off the audible warning tone

The audible warning tone can be turned off by simultaneously pressing the and

buttons for 4 seconds.

Note

The audible tone will sound each time the CABIN 400 is turned on and off.

3.12 When it freezes

Fully drain the water reservoir. Pull off the feed hose from the pump and drain it. Move the pump away from any residual water in order to avoid it freezing up. Protect the pump against knocks and bumps. Obviously the vehicle's main water feed line must also be drained in order to prevent frost damage to the solenoid valve.

The pumps in the water reservoir are fitted with a foam filter that envelops the pump. This filter has two functions:

1. Sound absorption: The filter prevents contact noise between the pumps and the

water reservoir

2. Keeping the system free of obstructions: The filter catches particles in the

water, which would otherwise be sucked in by the pump and foul the system (obstructions in the system would reduce cooling performance).

Cleaning the water pump filter

Perform the following operation at the same time as "Draining the water reservoir" on page 14.

1. Remove the foam filter from the pump.

2. Rinse the filter clean using fresh tap water.

3. Refit the filter around the pumps and put them back in the water reservoir.

Note

If you do not refit the filter, the system will become fouled. The OXYCELL must be replaced if it is allowed to become fouled.

The pumps in the water reservoir are maintenance-free. The materials used are environentally safe and will not affect the taste or smell of the water.

5 STORAGE MODE

5.1 When

The CABIN 400 should be set to storage mode, if you do not intend to use it for four weeks or more.

Why

The storage mode helps prevent chemical and bacteriological contamination of the water reservoir and the OXYCELL in the roof unit.

5.2 Function

Step 1

Clean the inside of the unit as indicated on the instructions label of the bottle of additive 2 (Bakterizid). First drain the water reservoir fully and refill it with fresh water. Only then should you add additive 2 to the water reservoir.

Note

When the “storage mode” has been activated, the water reservoir will no longer be automatically replenished. Water has to be poured into the water reservoir by hand.

Step 2: Drying the OXYCELL (roof unit)

1. Close the the OXYZONE unit's screen frame and outlet vents.

2. Add water by hand until the maximum level is reached and

pour in a bottle of additive 2. Activate the "storage mode" by pressing the ventilation and cooling buttons simultaneously for 4 seconds. LEDs L1 and L3 will flash. The system will now start to purge (the pumps will switch on at regular intervals). After about 20 minutes, the system will stop purging and the fan will then dry off the OXYCELL in the roof unit.

3. After approx. 1.5 hours all the LEDs will light up and remain lit. This indicates that

the CABIN 400 has been successfully set to storage mode.

6.3 Functional principles of the OXYCELL when cooling

This section goes into more detail than the section entitled "Function" on page 6; it will be of interest to readers who wish to know more about the cooling principles used.

A fan in the roof unit sucks in air from the outside. The incoming air is separated into two air streams within the OXYCELL: one air stream, which only comes into contact with a permanently dry surface in the OXYCELL, and a second air stream which flows across a different surface in the OXYCELL that is moistened by a sprinkler.

The air stream over the damp surface absorbs moisture and is allowed to escape through the roof unit. This cools the OXYCELL, thereby also cooling the air stream across the permanently dry surface in the OXYCELL. This cool, dry air flows through the OXYZONE into the caravan / camper.

7 TROUBLESHOOTING

The CABIN 400 is a robust system. Any problems that arise can most probably be attributed to reduced air throughput, insufficient water levels or problems with the water feed and return.

The "Problem solving" table simplifies the identification of possible causes of a problem and advises how problems can be solved.

If you are unable to solve a problem, we advise you to turn off the system and refer the problem to an authorised dealer.
