Emergency operation

x If the remote controller is lost or broken, use the

“force” switch button to operate the air
conditioner.

x If this button is pushed with the unit OFF, the air

conditioner will operate in Auto mode.

x If this button is pushed with the unit ON, the air

conditioner will stop running.

Airflow direction adjustment

1. Use the up-down swing and left-right swing

Within the temperature range provided in the following table, the air conditioner may stop
running and other anomalies may arise.

x If the temperature is too high, the air conditioner may activate the automatic protection

device. If so, the air conditioner may be shut down.

x If the temperature is too low, the heat exchanger of the air conditioner may freeze, leading

to water leakage or other malfunctions.

x With long-term cooling or dehumidification, at a relative humidity of above 80% (doors and

windows are open), there may be water condensation or dripping near the air outlet.

Conditions that will prevent the unit from running normally

x The fan of the indoor unit will not start running immediately after heating is started, this is to

avoid the blowing out of cool air.

x When it is cold and wet outside, the outdoor unit will develop frost over the heat exchanger

which will compromise the heating capacity. The air conditioner will start to defrost on order
to remedy this condition.

x During defrost, the air conditioner will stop heating for about 5-12 minutes.
x Vapour may arise from the outdoor unit during defrosting. This is not a malfunction and is

normal during the defrosting process.

x Heating will resume after defrosting has completed.

Note: The appearance and functions of the remote controllers may vary slightly from

model to model. Some indicators and functions on your remote control may not be
applicable to the model you have purchased.

Precautions

x Before first time use of the remote

controller, install the batteries and ensure
the “+”and “-” poles are correctly
positioned.

x Ensure the remote controller is pointed to

the signal receiving window, and that
there is no obstruction in between and the
distance is 8m at the maximum.

x Do not let the remote controller drop or

fling it at will. Do not let any liquid in the
remote controller. Do not expose the
remote controller directly to the sunlight or
excessive heat.

x If the remote controller does not function

normally, remove the batteries for 30
second before reinstall them. If that
doesn't work, replace the batteries.

x When replacing the batteries, do not mix

the new batteries with old ones or mix
batteries of different types, which could
cause failure of the remote controller.

x If the remote controller is not to be used

for a long period of time, remove the
batteries first, lest the leakage from them
may damage the remote controller.

x Properly dispose the discarded batteries.

Note:

This is a universal remote controller and may
cover a variety of models. Some of the
buttons may not be applicable to the
particular model you have purchased. If so,
these will not function on your model. (If a
specific function is not available on the air
conditioner, pressing the corresponding
button will have no effect).
