Test running - FIRST TIME OPERATION
z
Make sure that all the pipes and wires are connected.
z
Make sure that both the liquid valve and gas valve on the side of the outdoor unit
are COMPLETELY OPEN. (Top & Bottom Hex Valves)
Connect the indoor unit to the power source
Connect the mains wires to an independent power source socket of the correct rating.
Fit batteries in the remote control.
When operating for the first time - run the air-conditioner in cooling mode (SNOW FLAKE on wall
unit display) for 30 minutes on the lowest temperature setting. Then turn off using the remote
control. Wait for 3 minutes to allow the refrigerant to settle. Then run in heating mode (RED SUN
on wall unit display) for 20 minutes on highest temperature. Then switch off for 3 minutes before
setting to your desired temperature on cooling or heating modes.

Performance & Evaluation
Test the outdoor / indoor air temperatures.
Make sure that the temperature difference between the outdoor and indoor air is
greater than 8
o
C. The unit may not heat or cool if the selected temperature is not more than 8
degrees difference from the outdoor temperature.
8 Service & Maintenance
Check the indoor dust filters every 3 months, wash in warm water with washing up liquid only, dry
naturally.
Check the outdoor unit and ensure no plants or leaves/sticks etc can obstruct the fan operating,
and that air can flow freely through the rear cooling fins.
You system should be serviced and refrigerant levels checked every 1 – 2 years, please contact
us to arrange this.
If you ever notice a reduction in cooling or heating efficiency, first check the filters, if they are clear,
please contact us.

Error Codes
Your system can display different error codes. There are too many to list here but the most
common codes are:
E4 generally means a lack of refrigerant or too low pressure.
E5 can mean too high pressure, caused by a kinked pipe or defective valve.
Switch off if any error codes occur and contact us immediately, otherwise further damage may
occur.
dF is not an error code, it means your system is simply defrosting itself and will resume to normal
operation in a few minutes time. This is a standard feature and should be left to complete the
defrost, no action is necessary.
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.
IMPORTANT - Items to note:
z
Fix the machine firmly; otherwise it may produce noise and vibration.
z
If using wall brackets for the outdoor unit, bolt the unit to the brackets securely.
z
Install the outdoor unit where it will not disturb your neighbours.
z
IMPORTANT When switching between heating and cooling modes, switch off system for 3
minutes before changing the mode to allow the refrigerant to settle.
z
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.
z
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 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 cooling mode or
heating mode will give a more accurate temperature.
