GENERAL UNIT INFORMATION
I. PURPOSE
The Aircommand Ibis 3 air conditioning unit was designed for installation on the roof of a caravan or recreational vehicle to
provide reverse cycle heating and cooling. The unit is intended for vehicles with roofs that are from 25 to 85mm thick. The unit
must be installed so that it is within ±5° of the horizontal plane. It is important that the unit is installed properly according to the
recommended guidelines.
II. ENSURING EFFECTIVE OPERATION
The effectiveness of the air conditioner is dependent on several factors that contribute to the total heat load on the van. When
an Aircommand unit is installed in a van or motorhome Aircommand assumes that the vehicle manufacturer or owner has
properly assessed the potential heat load or sought expert advice and selected the appropriate capacity air conditioning unit.
Roof hatches will significantly increase the heat load into the caravan. Where possible avoid installing roof hatches or only install
hatches that can be effectively insulated. The increase in heat load far outweighs the gain from natural lighting.
The following actions can be taken to reduce peak heat load and help the air-conditioner deliver the most comfort:
Closing all doors, hatches, windows and blinds. Extend all annexes.
Position the vehicle so that the annex will face the sun and protect the windows from direct solar radiation.
Turning off unneeded appliances that might increase the heat load inside the van.
Cook outside if possible.
Park the caravan/RV in a shaded position.
In periods of extreme high temperature it is recommended to start the air conditioner earlier in the morning to greatly
improve its ability to cope with the expected peak heat load.
III. CONDENSATION
In areas of high humidity, the humid air within the van will cause “sweating” or condensation in parts of the unit as the humid,
warm air contacts the colder air discharged from the system. If this occurs please ensure the following:
Close all doors, hatches, windows and blinds to limit the ingress of warm humid air.
Avoid running the inside fan on LOW or AUTO in humid conditions. Running the fan on HIGH fan speed will result in higher
airflow and reduce the tendency to have condensation form.
Aircommand will not be held responsible for damage caused by condensation.
IV. GENERATORS
The Ibis 3 is designed to run using mains power, however many owners may want to use portable generators to run the unit
when in remote locations. Any generator used should deliver high quality, pure sine wave, alternating current at 50Hz, and be
able to handle the compressor start up demand. Given the vast range in quantity and quality of generators on the market
Aircommand cannot recommend a specific model or brand. Discuss your specific requirements with the generator supplier
directly and consider their recommendations.
Aircommand will not be held responsible for damages due to the use of improper generators and such use may void your
warranty.
