•
Carry out test run to confi rm that no abnormality occurs after the installation. Then, explain to user the operation, care and maintenance as stated in
instructions. Please remind the customer to keep the operating instructions for future reference.
•
If there is any doubt about the installation procedure or operation, always contact the authorized dealer for advice and information.
Do not use unspecifi ed cord, modifi ed cord, joint cord or extension cord for power supply cord. Do not share the single outlet with other electrical
appliances. Poor contact, poor insulation or over current will cause electrical shock or fi re.
Do not tie up the power supply cord into a bundle by band. Abnormal temperature rise on power supply cord may happen.
Keep plastic bag (packaging material) away from small children, it may cling to nose and mouth and prevent breathing.
Do not purchase unauthorized electrical parts for installation, service, maintenance and etc.. They might cause electrical shock or fi re.
Do not modify the wiring of Tank Unit for installation of other components (i.e. heater, etc). Overloaded wiring or wire connection points may cause
electrical shock or fi re.
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 fi re.
For water circuit installation work, follow to relevant European and national regulations (including EN61770) and local plumbing and building
regulation codes.
Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, electrical shock or fi re.
Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fi re.
Install at a strong and fi rm 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.
This equipment is strongly recommended to be installed with Residual Current Device (RCD) on-site according to the respective national wiring
rules or country-specifi c safety measures in terms of residual current.
Only use the supplied or specifi ed installation parts, else, it may cause unit vibrate loose, water leakage, electrical shock or fi re.
The unit is only for use in a closed water system. Utilization in an open water circuit may lead to excessive corrosion of water piping and risk of
incubating bacteria colonies, particularly Legionella, in water.
If there is any doubt about the installation procedure or operation, always contact the authorized dealer for advice and information.
Select a location where in case of water leakage, the leakage will not cause damage to other properties.
When installing electrical equipment at wooden building of metal lath or wire lath, in accordance with electrical facility standard, no electrical contact
between equipment and building is allowed. Insulator must be installed in between.
Any work carried out on the Tank Unit after removing the front panel which is secured by screws, must be carried out under the supervision of
authorized dealer and licensed installation contractor.
For cold water supply has a backfl ow regulator, check valve or water meter with check valve, provisions for thermal expansion of water in the hot
water system must be provided. Otherwise it will cause water leakage.
The piping installation work must be fl ushed before Tank Unit is connected to remove contaminants. Contaminants may damage the Tank Unit
components.
The installation may be subjected to building regulation approval applicable to respective country that may require to notify the local authority
before installation.
The Tank Unit must be shipped and stored in upright condition and dry environment. It may laid on its back when being moved into the building.
This unit must be properly earthed. The electrical earth must not be connected to a gas pipe, water pipe, the earth of lightening rod or a telephone.
Otherwise there is a danger of electrical shock in the event of an insulation breakdown or electrical earth fault in the Tank Unit.
