Sparrow MK4 General 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.

The unit is not designed to be installed on sleeper cabs of

prime movers although may be suitable in some circumstances.

Warranty will be voided if installed in such circumstances

without the prior approval of Aircommand Australia.

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 north 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:

• 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 condensate from the inside air which will drain

onto the van roof. The quantity of condensate will be

dependent on the humidity in the air. Avoid running the inside

fan on LO or AUTO in such conditions. Running the fan on HI

fan speed will result in higher airﬂ ow 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 speciﬁ c model or brand.

Discuss your speciﬁ c 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.
