Disposal Guideline
03.Maintenance
1. Keep the control interface clean with the use of a
soft dry cloth only. If a cleaning solution is needed,
use a very mild soap solution to dampen the cloth.
Do not spray or squirt any liquid onto your control
interface.
2. Do not use solvent base cleaner, which can cause
damage to the control interface.
3. When cleaning, be careful not to accidentally press
any Buttons, TURN-OFF the unit to ensure that no
adverse unit operation is initiated by accidentally
pressing any buttons.
4. Be careful not to press hard into the display screen,
as it may get damaged.
5. Ensure that the temperature sensor is always clean
and free of dust or dirt build-up to maintain sensor
accuracy.
6. Do not pull apart or attempt to service the
control interface, should you need service to the
device, contact ActronAir Service Department on
1800 119 229.
04. Operational Precautions
Read all instructions in this manual before operating
the air conditioning unit. Failure to do so may result in
damage to the unit and void your warranty.
ACCESS PANELS AND GUARDS: NEVER remove any
access panels or guards as this could cause injury
from electric shock and burns from extremely hot
components. Never allow any bodily parts such as
fingers or objects to protrude through the fan guards
or any other opening as they could cause personal
injury and damage the air conditioner.
SUPERVISION OF CHILDREN AND INFIRM PERSONS:
This appliance is not intended for use by young children
or infirm person unless they have been adequately
supervised by a responsible person to ensure that they
can use the appliance safely. Young children should
1. Do not dispose off the waste electrical and electronic
equipment with local council waste. These must be
disposed off through the council designated hazardous
waste collection centre.
2.The equipment may contain hazardous substances,
improper or incorrect disposal may have a negative effect
on human health and on the environment.

Operation Manual LC7-2 Wall Control

be supervised to ensure that they do not play with the
appliance.
RETURN AIR FILTER: The air conditioner must never
be operated without a return air filter as this will allow a
build up of dust and other contaminantson the indoor
coil. This is very difficult to clean and causes the system
to operate inefficiently or even fail.
CRANKCASE HEATER PRECAUTION: The main
power (Outside switch board) to the system must
be kept ON at all times to prevent damage to the
outdoor compressor unit. Should the main power be
disconnected or interrupted for 6 hours or longer, then
no attempt should be made to start the system for 2
hours after the power has been restored to outdoor
unit. This allows the compressor to warm up, and
remove any liquid refrigerant that may cause damage.

06.Features
1
Auto-Restart After Power Failure
Should a power failure occur whilst the air conditioner is running,
the wall control will restart the air conditioner in the same mode
when the power is restored, if this option is selected.
2
Dual/Triple Wall Control Operation (Optional)
Up to three wall controls can be installed on one system. This is
particularly useful on larger buildings, where you can have up
to three wall controllers in different locations. All connected
controllers will mimic any adjustment made in one controller
(restrictions apply).
3
Room Temperature Display with One Touch
Press the or button and the set temperature display will
change to show the room temperature for 10 seconds.
4
Auto Defrost Function (Heating Mode)
At certain outdoor conditions (low temperature) there may be a
build up of frost on the outdoor heat exchanger. This gradual build
up of frost reduces the performance of the air conditioner. The
system detects this frost build up and will automatically activate the
defrost mode.
The defrost mode is displayed on the wall control by flashing the
DEFROST indicator every 10 seconds.
5
Hot Start Function (Heating Mode)
When the air conditioner starts in heating mode, the indoor fan is
delayed for a short period of time, this allows the heat exchanger
to warm up before the air flow starts, thus minimising cold drafts.
The hot start feature also activates itself when the system finishes
defrosting.
6
Filter Clean Light
The system monitors the accumulated run time of the air
conditioner and after a preset number of hours have expired,
the FILTER indicator will flash, indicating it’s time to check if filter
requires cleaning.
7
Self Diagnosis
In the unlikely event that a fault develops with the air conditioner
the system will detect a fault and displays the relevant fault code on
the wall control.
NOTE
Some applications may require cleaning of the filter at more regular
intervals.
