This symbol denotes item that is PROHIBITED from doing.
1. Do not modify the machine, part, material during repairing service.
2. If wiring unit is supplied as repairing part, do not repair or connect the wire even only partial wire break. Exchange the whole wiring
unit.
3. Do not wrench the fasten terminal. Pull it out or insert it straightly.
4. Engage dealer or specialist for installation and servicing. If installation of servicing done by the user is defective, it will cause water
leakage, electrical shock or fire.
5. Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electric shock or fire.
6. Use the attached accessories parts and specified parts for installation and servicing. Otherwise, it will cause the set to fall, water
leakage, refrigerant leakage, fire or electrical shock.
7. 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.
8. Do not install outdoor unit near handrail of veranda. When installing outdoor unit at veranda of high rise building, child may climb up
to outdoor unit and cross over the handrail and causing accident.
9. For electrical work, follow the local national wiring standard, regulation and the 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.
10. 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 electric shock in case equipment breakdown or insulation breakdown.
11. Do not use joint cable for indoor / outdoor connection cable. Use specified indoor / outdoor connection cable, refer to Installation
Instructions CONNECT THE CABLE TO THE INDOOR UNIT and connect tightly for indoor / outdoor connection. Clamp the cable so
that no external force will be acted on the terminal. If connection or fixing is not perfect, it will cause heat up or fire at the connection.
12. When install or relocate Air to Water Heatpump indoor / outdoor unit, do not let any substance other than the specified refrigerant, eg.
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.
13. 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 of copper pipes used with R410A 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 40 mg/10 m.
14. During installation, install the refrigerant piping properly before run the compressor. Operation of compressor without fixing
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.
15. During pump down operation, stop the compressor before remove the refrigeration piping. Removal of refrigeration piping while
compressor is operating and valves are opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and
result in explosion, injury etc.
16. After completion of the installation servicing confirm there is no leakage of refrigerant gas. It may generate toxic gas when the
refrigerant contacts with fire.
17. Ventilate the room if there is refrigerant gas leakage during operation. Extinguish all fire sources if present. It may cause toxic gas
when the refrigerant contacts with fire.
18. Only use the supplied or specified installation parts, else, it may cause unit vibrate loose, water/refrigerant leakage, electrical shock
or fire.

19. The unit is only for use in a closed portable water system. Utilization in an open water circuit or non-portable water circuit, may lead to
excessive corrosion of the water piping and risk of incubating bacteria colonies, particularly Legionella, in water.
20. Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.
21. Do not dismantle refrigerant piping using pipe wrench. It might deform the piping and cause the unit to malfunction.
22. Select a location where in case of water leakage, the leakage will not cause damage to other properties.
23. Do not locally purchase electrical parts of the product for the purpose of installation, service, maintenance and etc. They might cause
electrical shock or fire.
24. Do not branch the power from terminal block to heater tape. Overloaded terminal block will cause electrical shock or fire.
25. Installation or servicing work. It may need two people to carry out the installation or servicing work.
26. Do not use unspecified cord, modified 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 fire.
27. Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the flare
may break and cause refrigerant gas leakage.
1. Do not install the air-to-water heatpump indoor unit and outdoor unit at place where leakage of flammable gas may occur. In case gas
leaks and accumulates at surrounding of the unit, it may cause fire.
2. Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage
the furniture.
3. It may need two persons to carry out the installation work. The weight of indoor / outdoor unit might cause injury if carried by one
person.
4. Do not touch outdoor unit air inlet and aluminium fin. It may cause injury.
5. Select an installation location which is easy for maintenance.
6. Pb free solder has a higher melting point than standard solder; typically the melting point is 50F - 70F (30C - 40C) higher. Please
use a high temperature solder iron. In case of the soldering iron with temperature control, please set it to 700 ± 20F (370 ± 10C).
Pb free solder will tend to splash when heated too high (about 1100F / 600C).
7. Power supply connection to the indoor unit.
1. Power supply point should be in easily accessible place for power disconnection in case of emergency.
2. Must follow local national wiring standard, regulation and this installation instruction.
3. Strongly recommended to make permanent connection to a circuit breaker. It must be a double pole switch with a minimum
3.0 mm gap.
- Use approved 30A circuit breaker for power supply 1
- Use approved 30A circuit breaker for power supply 2
- Use approved 15A/16A circuit breaker for power supply 3 (Not applicable for SXC09D3E5)
8. Do not release refrigerant during piping work for installation, servicing, re-installation and during repairing a refrigeration parts. Take
care of the liquid refrigerant, it may cause frostbite.
