HOW TO CHANGE THE BATTERIES IN THE REMOTE CONTROLLER
CIRCUIT BREAKER
When you do not use the room air conditioner, set the circuit breaker to “OFF”.
HOW TO USE THE AIR CONDITIONER EFFECTIVELY
1. An average room temperature setting is probably the best for you as well as being
economical.
• Excessive cooling or heating is not recommended for health reasons. High electricity
bills may also result.
• Close the curtains or blinds to prevent heat from flowing into or escaping the room as
well as to make more effective use of electricity.
2. At intervals, the doors and windows should be opened to let fresh air in.
CAUTION
Make sure the room is ventilated when operating the air conditioner
at the same time as other heating appliances.
3. Using the timer is recommended before going to sleep or going out.
4. The following must never be used for cleaning the indoor and outdoor units:
• Benzine, thinner and scrub can damage plastic surfaces or coating.
• Hot water above 40°C can shrink the filter and deform plastic parts.
5. Do not block the air intake and air outlet.
• Do not block the air outlets and intakes of the indoor and outdoor units with curtains
or other obstacles which could degrade air conditioner performance and cause unit
failure.
TEMPORARY SWITCH
If the remote controller does not work due to battery
failure, press this switch to start and stop operation.
•
This temporary operation will be at the setting made
most recently. (The unit will immediately go into
automatic operation once power is switched on.)
TEMPORARY SWITCH
CAUTION
1. Do not mix new and old batteries, or different type of
batteries together.
2. Remove the batteries when you do not use the remote
controller for 2 or 3 months.
Install the new batteries.
The direction of the batteries should match the marks in
the case.
Remove the cover as shown in the figure and remove the
old batteries.
