 WARNING 

18. 

This equipment is strongly recommended to be installed with Residual Current Device (RCD) on-site according to the respective 
national wiring rules or country-specific safety measures in terms of residual current. 

 

19. 

The unit is only for use in a closed water system. Utilization in an open water system may lead to excessive corrosion of the water 
piping and risk of incubating bacteria colonies, particularly Legionella, in water. 

 

20.  If there is any doubt about the installation procedure or operation, always contact the authorized dealer for advice and information. 

 

21.  Select a location where in case of water leakage, the leakage will not cause damage to other properties. 

 

22. 

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. 

 

23. 

This installation may be subjected to building regulation approval applicable to respective country that may require to notify the local 
authority before installation. 

 

24. 

Any work carried out on the Mono bloc 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. 

 

25. 

This unit must be properly earthed, the electrical earth must not be connected to a gas pipe, water pipe, the earth of a lightning 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 
Mono bloc unit. 

 

 

 CAUTION 

1. 

Do not install the Mono bloc unit in areas where there is a risk of flammable gas leakage. There is a risk of fire if flammable gas 
accumulates near or around the Mono bloc unit. 

 

2. 

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. 

 

3. 

Make sure the power supply cord does not contact with hot part (i.e. water piping). High temperature may cause insulator of power 
supply cord damage hence electrical shock or fire. 

 

4. 

Do not touch the sharp aluminum fins or edges of metal parts. 
If you are required to handle sharp parts during installation or servicing, please wear hand glove. 
Sharp parts may cause injury.  

 

 

5. 

Do not apply excessive force to water pipes that may damage the pipes. If water leakage occurs, it will cause flooding and damage to 
other properties. 

 

6. 

Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water leakage may happen and may 
cause damage to properties of the user. 

 

7. 

The piping installation work must be flushed before the Mono bloc unit is connected to remove contaminants. Contaminants may 
damage the Mono bloc unit components. 

 

8.  Select an installation location where it is accessible for maintenance. 

 

9. 

Power supply connection to the Mono bloc 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. It must be a double pole switch with a minimum 
3.0 mm gap. 

Power supply 1: Use approved 40A circuit breaker 

Power supply 2: Use approved 40A circuit breaker 

 

10.  Ensure the correct polarity is maintained throughout all wiring. Otherwise, it will cause electrical shock or fire. 

 

11. 

After installation, the installer is obliged to verify correct operation of the Mono bloc unit. Check the connection point for water leakage 
during test run. If leakage occurs, it will cause damage to other properties. 

 

12. 

Installation work. 
Four or more people are required to carry out the installation work. The weight of Mono bloc unit might cause injury if carried by less 
than four people.
