Revision V1
Correction
Check that mains power is plugged into van and that the supply is
switched ON.
Check the van's air-conditioner power circuit breaker is 'ON'
Check the remote control screen. If blank then replace batteries
See Figure 23 - Remote control batteries.
Stand close to unit and point remote directly towards the IR
receiver in the plenum. Test operation of remote. If there is no
'beep' from the air conditioner then replace batteries and re test.
See Figure 23 - Remote control batteries.
Test air conditioner operation by using manual operation button.
See Figure 26 - Status display in corner of inside plenum.

Contact Aircommand Australia for specialist advice on fault
correction and access to our service agents.
Remove filter, clean & replace. See Figure 16 - Remove filter from
plenum. Clean filter every 4 weeks, more frequently with high use
Ensure that at least 2 outlets are opened. Highest capacity occurs
when all 4 outlets are fully opened.
Check that debris has not blocked the external air intake of the roof
top unit. Clear intake grille.
Take action to reduce your peak heat load – extend awnings, close
blinds, windows & hatches, start air conditioner earlier in the
morning.
Discuss your expected heat load with your caravan supplier and size
the air conditioning capacity to suit.
Outside air temperature exceeds the unit's operating temperature
range.
Discuss expected heat loss with your caravan supplier and size air
conditioning capacity to suit.
Outside air temperature is below the unit's operating temperature
range.
During cooling on very hot days the compressor overload may be
activated. This is to protect the unit. Take all steps to reduce heat
load on caravan.
During heating on cold mornings the unit will periodically enter
automatic de-ice mode to clear ice from its outside coil. Normal
operation will resume once ice has been melted.
This is normal. The unit will dehumidify air inside the caravan and
provide more comfortable living conditions.
In humid conditions close doors, windows and hatches.
Run the inside fan on High or Medium.
Avoid using Low or Auto fan speeds in these conditions
This is normal. During heating on cold mornings the unit will
periodically enter automatic de-ice mode to clear ice from the
outside coil. Normal operation will resume once ice has been
melted.
