CAUTION

1. Paste the enclosed refrigerant label adjacent to the charging and/or recovering location.

2. Clearly write the charged refrigerant quantity on the refrigerant label using indelible ink. Then, place the included

transparent protective sheet over the label to prevent the writing from rubbing off.

3. Prevent emission of the contained fluorinated greenhouse gas. Ensure that the fluorinated greenhouse gas is

never vented to the atmosphere during installation, service or disposal. When any leakage of the contained

fluorinated greenhouse gas is detected, the leak shall be stopped and repaired as soon as possible.

4. Only qualified servi

ce personnel are allowed to access and service this product.

5. Any handling of the fluorinated greenhouse gas in this product, such as when moving the product or recharging

the gas, shall comply under (EC) Regulation No. 842/2006 on certain fluorinated greenhouse gases and any

relevant local legislation.

6. Periodical inspections for refrigerant leaks may be required depending on European or local legislation.

7. Contact dealers, installers, etc., for any questions.

This product contains fluorinated greenhouse gases covered by the Kyoto Protocol

Warnings on refrigerant leakage

Check of concentration limit

The room in which the air conditioner is to be installed requires a design that in the event of refrigerant

gas leaking out, its concentration will not exceed a set limit.

The refrigerant R410A which is used in the air conditioner is safe, without the toxicity or combustibility of ammonia,

and is not restricted by laws to be imposed which protect the ozone layer. However, since it contains more than

air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R410A

is almost non-existent.

If a conditioner system is to be installed in a small room, select a suitable model and installation procedure so that

if the refrige

rant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency,

measures can be made before injury can occur).

In a room where the concentration may exceed the limit, create an opening with adjacent rooms, or install

mechanical ventilation combined with a gas leak detection device.

The concentration is as given below.

The concentration limit of R410A which is used in air conditioners is 0.3 kg/m

NOTE

The minimum indoor floor area compared with the amount of refrigerant is roughly as follows:
