Do not add or replace refrigerant other than specifi ed type. It may cause product damage, burst and injury etc.
Do not use joint cable for Indoor / Outdoor Unit connection cable. Use specifi ed Indoor / Outdoor Unit connection cable, refer to instruction 5 CONNECT
THE CABLE TO THE INDOOR UNIT and connect tightly for Indoor / Outdoor Unit connection. Clamp the cable so that no external force will be acted
on the terminal. If connection or fi xing is not perfect, it will cause heat up or fi re at the connection.
For electrical work, follow the national regulation, legislation and this installation instructions. An independent circuit and single outlet must be used. If
electrical circuit capacity is not enough or defect found in the 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 authorized dealer or specialist for installation. If installation done by the user is incorrect, it will cause water leakage, electrical shock or fi re.
•
This is a R32 model, use piping, fl are nut and tools which is specifi ed for R32 refrigerant. Using of existing (R22) piping, fl are nut and tools may cause
abnormally high pressure in the refrigerant cycle (piping), and possibly result in explosion and injury.
•
Thickness for copper pipes used with R32 must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.
•
It is desirable that the amount of residual oil is less than 40mg/10m.
When install or relocate Indoor Unit, do not let any substance other than the specifi ed 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.
For refrigeration system work, 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 weight of the set. 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.
During installation, install the refrigerant piping properly before running the compressor. Operation of compressor without fi xing refrigeration piping and
valves at opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
During pump down operation, stop the compressor before removing the refrigeration piping. Removal of refrigerant piping while compressor is operating
and valves are opened will cause suck-in of air, abnormal high pressure in refrigerant cycle and result in explosion, injury etc.
Tighten the fl are nut with torque wrench according to specifi ed method. If the fl are nut is over tightened, after a long period, the fl are may break and
cause refrigerant gas leakage.
After completion of installation, confi rm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant contacts with fi re.
Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant contacts with fi re.
Use the attached accessories parts and specifi ed parts for installation. Otherwise, it will cause the set to fall, water leakage, fi re or electrical shock.
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 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.
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 Indoor Unit after removing any panels which is secured by screws, must be carried out under the supervision of authorized
dealer and licensed installation contractor.
This system is multi supply appliance. All circuits must be disconnected before accessing the unit terminals.
The piping installation work must be fl ushed before Indoor Unit is connected to remove contaminants. Contaminants may damage the Indoor Unit components.
This installation may be subjected to building regulation approval applicable to respective country that may require to notify the local authority before installation.
Be aware that refrigerant may not contain an odour.
This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and telephone.
Otherwise, it may cause electrical shock in case of equipment breakdown or insulation breakdown.
Do not install the Indoor Unit at place where leakage of fl ammable gas may occur. In case gas leaks and accumulates at surrounding of the unit, it
may cause fi re.
Prevent liquid or vapor from entering sumps or sewers since vapor is heavier than air and may form suffocating atmospheres.
Do not release refrigerant during piping work for installation, re-installation and during repairing a refrigeration parts. Take care of the liquid refrigerant,
it may cause frostbite.
Do not install this appliance in a laundry room or other high humidity location. This condition will cause rust and damage to the unit.
Make sure the insulation of power supply cord does not contact hot part (i.e. refrigerant piping) to prevent from insulation failure (melt).
Do not apply excessive force to water pipes that may damage the pipes. If water leakage occurs, it will cause fl ooding and damage to other properties.
Select an installation location which is easy for maintenance.
Incorrect installation, service or repair of this Indoor Unit may increase the risk of rupture and this may result in loss or damage of property or injury.
Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the furniture.
Power supply connection to Indoor Unit.
•
Power supply point should be in easily accessible place for power disconnection in case of emergency.
•
Must follow local national wiring standard, regulation and this installation instruction.
•
Strongly recommended to make permanent connection to a circuit breaker.
- Power Supply 1: For WH-UD03JE5* and WH-UD05JE5*, use approved 15/16A 2-poles circuit breaker with a minimum contact gap of 3.0mm.
- Power Supply 2: Use approved 16A 2-poles circuit breaker with a minimum contact gap of 3.0mm.
Ensure the correct polarity is maintained throughout all wiring. Otherwise, it will cause electrical shock or fi re.
After installation, check the water leakage condition in connection area during test run. If leakage occurs, it will cause damage to other properties.
Installation work.
It may need two or more people to carry out the installation work. The weight of Indoor Unit might cause injury if carried by one person.
2
For WH-UD07JE5* and WH-UD09JE5*, use approved 25A 2-poles circuit breaker with a minimum contact gap of 3.0mm.
