other electrical appliances. Poor contact, poor insulation or over current will cause electrical shock or fire.
3. Do not tie up the power supply cord into a bundle by band. Abnormal temperature rise on power supply cord may happen.
4. Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.
5. Do not sit or step on the unit, you may fall down accidentally.
6. Keep plastic bag (packaging material) away from small children, it may cause suffocation.
7. Do not use pipe wrench to install refrigerant piping. It might deform the piping and cause the unit to malfunction.
8. Do not purchase unauthorized electrical parts for installation, service, maintenance and etc.. They might cause electrical shock or fire.
9. Do not modify the wiring of Indoor Unit for installation of other components (i.e. heater, etc.). Overloaded wiring or wire connection
points may cause electrical shock or fire.
10. Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury etc.
11. For electrical work, follow local wiring standard, regulation and this installation instruction. An independent circuit and single outlet
must be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or fire.
12. For water circuit installation work, follow to relevant European and national regulations (including EN61770) and local plumbing and
building regulation codes.
13. Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, electrical shock or
fire.
14.
 This is a R410A model, when connecting the piping, do not use any existing (R22) pipes and flare nuts. Using such same may
cause abnormally high pressure in the refrigeration cycle (piping), and possibly result in explosion and injury. Use only R410A
refrigerant.
 Thickness or copper pipes used with R410A must be 0.8 mm or more. Never use copper pipes thinner than 0.8 mm.
 It is desirable that the amount of residual oil is less than 40mg/10m.
15.
When install or relocate Indoor / Outdoor Unit, do not let any substance other than the specified refrigerant, e.g. air etc. mix into
refrigerant cycle (piping).
Mixing of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
16. Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fire.
17. Install at a strong and firm location which is able to withstand the set’s weight. If the strength is not enough or installation is not
properly done, the set will drop and cause injury.
