GENERAL SPARROW UNIT INFORMATION
I. PURPOSE
The Aircommand Sparrow air conditioning unit is designed for installation on the roof of a caravan or recreation vehicle to
provide reverse cycle heating and cooling.
 The roof must be capable of supporting the weight of the unit (29kg).
 The mechanisms for raising pop-top roofs must be capable of operating with the added weight of this air-conditioning unit.
 The absolute minimum thickness of the roof must not be less than 25mm.
 The maximum thickness of the roof must not exceed 125mm.
 Trimming of the ductwork will be necessary depending on the roof thickness. You will need to supply longer M8 hold down
bolts if you roof thickness exceeds 85mm.
It is important that the unit is installed properly and according to the recommended guidelines.
Aircommand will not be held responsible for problems relating to incorrect or improper installation methods.
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 and selected the appropriate capacity air-conditioning unit.
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 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 if possible.
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 discharge 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 Sparrow Mk4 is designed to run using mains power, however many owners may want to use portable generators to run
them 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.
