Your system can display different error codes. These are generally used by our Engineers to
determine the fault; here we have listed them below for your convenience.
Error code shown on display
Meaning of Error
Flashing LED on
Outdoor PCB
Note: Above errors are for the outdoor PCB to match with the error displayed on the indoor unit.
Outdoor PCB Flashing LED Codes
(this is a normal function)
Switch off if any error codes occur and contact us immediately, otherwi se further damage may
occur
which will be outside the scope of warranty.
In wintertime you may notice steam rising from the outdoor unit during defrost, this is normal. It is also
common for the outdoor unit to drip water in the winter; this is the moisture condensing on the cold
copper coils.
Please contact us if you have any doubts about the correct operation of your system.
You must contact us first for any service or warranty issues, no unauthorized work should be carried out
on your system, any such unauthorized work will not be paid by us and may invalidate any warranty.
IMPORTANT - Items to note:
l Fix the machine firmly; otherwise it may produce noise and vibration, or blow over in high winds.
l
If using wall brackets for the outdoor unit, bolt t he unit to the brackets securely, check all bolts and
serviceability of brackets and all fixings often, service or replace as required to prevent bracket failure
and injury or death. Air Conditioning Centre
cannot accept any liability for damage to property or
persons caused by insufficient servicing or checking fastness and safety of all components.
l Install the outdoor unit where it will not disturb your neighbo urs. You may require planning permission in
some areas, if in doubt always check first with your
Local Council before proceeding.
l IMPORTANT: When switching between heating and cooling modes, switch off system for 3 minutes
before changing the mode
to allow the refrigerant to settle.
l
When using heating mode, the indoor unit fan will not operate until sufficient heat has been generated
by the outdoor unit, this may take several minutes initially each time heating is selected.
Please be
patient and wait for the indoor unit fan to operate and blow warm air.
l
AUTO MODE is designed to keep the room at a rough ambient temperature using heating and cooling.
This is more useful if you are leaving the room unattended and just want to keep it at an average
temperature as it is not that precise for temperature accuracy. The idea is designed to use minimal
electricity so the temperature range is +/- 5 degrees either way from where you have set it, this avoids
the machine heating and cooling all day and ‘fighting’ itself using lots of power unnecessarily.
You will
find that if you are occupying the room then either co oling mode or heating mode will give a
more accurate temperature.
