1. PURPOSE The Aircommand CORMORANT 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 45kg The absolute minimum thickness of the roof must not be less than 25mm Standard fittings will allow installation on a roof up to 85mm thick Installations on thicker roofs will require custom ducting and hold down bolts Trimming of the ductwork will be necessary if the roof thickness is less than 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 e g size and heat load of the van When an Aircommand unit is installed in a van or motorhome Aircommand assumes that the vehicle is well insulated 25mm of foam minimum in all walls and roof that the windows are of moderate size preferably double glazed and the roof hatches are moderate insulated and airtight when closed Other methods of reducing heat load include Closing all doors hatches windows and blinds Position the vehicle so if an annex is used it will face the sun and protect the windows from direct radiation Turning off appliances that might increase the heat load2.

6. Ensuring the caravan RV is parked 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 high heat load HI 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 Closing all doors hatches windows and blinds to limit the ingress of warm humid air During operation the air conditioner will remove large quantities of water from the inside air and if warm humid outside air is limited then so the condensation will reduce greatly Avoid running the inside fan on LO or AUTO in such conditions Running the fan on HI 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 CORMORANT unit is equipped with a gen kit that allows it to be started using a generator Any generator used should have a steady full sine wave at 50hz and be able to handle the compressor start up demand However given the vast range in quantity and quality of generators on the market Aircommand cannot recommend a specific model or brand We do suggest a minimum output of 2 8 Kw This recommendation doesnot include allowances to run auxiliary
