As in homes, many different products are used in the construction of OTAG
385, such as carpet, linoleum, plywood, insulation, flooring. In the use of
different materials, odor sensitivity is more obvious. Since OTAG 385 has a
small living space, the air exchange inside is significantly less than the house.
These products can outgas different chemicals, including formaldehyde, when
new or when exposed to high temperatures and/or humidity. This outgassing,
along with minimal air exchange, can cause irritation of the eyes, nose, and
throat, and sometimes headaches, nausea, and various asthma-like
symptoms. The elderly and young children, as well as anyone with asthma,
allergies or lung problems, may be more sensitive to the effects of gassing.
Ventilation
It is very important to ventilate the OTAG 385 to reduce exposure to chemicals
from outgassing. Ventilation should be done frequently after purchase and
when temperatures and humidity rise. Note that gas output is accelerated by
heat and humidity. Open windows, vents and doors. Use natural ventilation or
a fan to expel stale air. Reducing airflow by sealing the OTAG 385 increases
the formaldehyde level of the vehicle.
Do not smoke
Smoking inside the OTAG 385 will damage the caravan and release
formaldehyde and other toxic chemicals.
Safety
Passenger Transportation
Since there is no seat belt in OTAG 385 and in order to balance the weight
distribution, you should not travel in OTAG 385 while driving.
Tire Safety
Properly maintained tires improve handling and stopping.
Tools and Equipment
Appliances (stove, refrigerator, etc.) and equipment (hot water heater, oven,
etc.) typically run on LPG. LPG is flammable and is under high pressure.
Misuse may cause fire and/or explosion. Be sure to follow all instructions and
warnings in the manual, as well as in the device and equipment specific user
manuals.
Mold
Mold and mildew spores are present in indoor and outdoor environments. In
order to keep all mold and mildew spores under control, check humidity and
ventilate your caravan regularly. A healthy ventilation should be provided to
control humidity.
Chemical Sensitivity
Immediately after the OTAG 385 is purchased, and sometimes after a long
period of inactivity, a strong odor and/or chemical sensitivity may be
experienced. It is not a fault of OTAG 385.

Tips for Checking Condensation
Uses where it is important to let excess moisture out:
- Bathroom
- Washing dishes
- Hair drying
- Cooking
Avoid dead air spaces as shown!
- Use of a fan to ensure air circulation.
- Leaving cabinets and cabinet doors partially open.
- Keep the temperature as reasonably cool as possible to help alleviate
condensation in the environment.
- OTAG 385 needs to breathe. It will smell when airtight.
- Let some warm air out and outside air in.
- Do not allow humid indoor air to be recycled from use and provide
reasonable ventilation.
Medical Advice
Questions about the effects of formaldehyde on your health should be
addressed to your doctor or local health department.
Long-Term Use Effects
- In long-term use of OTAG 385, it is necessary to be prepared for
condensation and humid conditions that may be encountered.
- In cold weather, when the relative humidity of the indoor air is high,
moisture may condense on the inner surfaces of OTAG 385. This is
exacerbated by the fact that OTAG 385’ insulated walls are much thinner
than house walls.
- The relatively small volume and tight, compact nature of the OTAG 385
mean that even a few passengers’ normal living activities will lead to rapid
moisture saturation.
- Water vapor will condense as moisture inside windows and walls, or as
frost or ice in cold weather, unless it is carried outside by ventilation or
condensed with a dehumidifier.
- Inside the walls or ceiling, warped or stained panels can also condense
out of sight.
- The appearance of these conditions can indicate a serious problem.
When signs of excessive humidity and condensation appear on the OTAG
385 it is important to take action to minimize their effects.

Mold
Molds are microscopic organisms that occur naturally, indoors and out, in
almost any environment. Mold formation in OTAG 385 occurs due to negative
reasons. Molds that are not controlled and tackled can degrade materials such
as aluminum and fabric. Therefore, color changes due to mold may occur. It is
necessary to analyze the potential risks posed by mold.
Factors Contributing to Mold Growth
For mold growth to occur, indoor or outdoor temperatures must be between 4°
and 33°C, and it must also have a source of moisture such as humidity,
stagnant water, moist materials. The fastest growth inside OTAG 385 is due to
its hot and humid condition.
Inhibition of Mold Growth
- Checking relative humidity can prevent mold and mildew growth.
- The use of air conditioners in hot climates will reduce the relative humidity.
- Ventilation is available in the kitchen area.
- To prevent mold growth, using vents when preparing food is an important
factor, even in cold weather.
- Also, opening windows during these activities will help with (natural)
ventilation.
- In extremely humid conditions, using a dehumidifier may help.
- Regular cleaning of mold, which is caused by frequent use of KMP190
and/or growing, is an important preventive measure.
- Any spills should be wiped up quickly and dried as soon as possible.
- Avoid leaving damp items lying around.
- On safe surfaces use mold or mildew-killing cleaning products.
- Check the sealing wicks regularly and reseal as necessary to prevent water
leaks.
- Maintenance of the OTAG 385 and its accessories, as described in both
this manual and accompanying literature, will provide the best protection for
the OTAG 385.
Winter Travel
Traveling in sub-freezing temperatures will require certain precautions to
protect the plumbing system and personal belongings from damage by
freezing.
It is necessary to clear the snow accumulations on the pop-up.
Whenever possible, the heat should be kept at a constant temperature.
It is easier for the heater to keep the room temperature constant than to let
the OTAG 385 temperature drop to 10°C and then try to raise it to room
temperature.
When parking in temperatures below freezing, be sure to have a full supply
of LPG or diesel available and plug into a 220V power source whenever
possible.
Leave cabinet doors, wardrobes, and bedroom doors partially open to allow
warm air to circulate around plumbing lines and fixtures.
