1. Safety Precautions 
  Read the following “SAFETY PRECAUTIONS” carefully before installation of (Mono bloc) Air-to-Water Heatpump 
system (hereafter referred to as “Mono bloc unit”). 
  Electrical works and water installation works must be done by licensed electrician and licensed water system 
installer respectively. Be sure to use the correct rating and main circuit for the model to be installed. 
  The caution items stated here must be followed because these important contents are related to safety. The 
meaning of each indication used is as below. Incorrect installation due to ignorance or negligence of the 
instructions will cause harm or damage, and the seriousness is classified by the following indications. 
 
 WARNING 
This indication shows the possibility of causing death or serious injury. 
 CAUTION 
This indication shows the possibility of causing injury or damage to properties only. 
 
 
The items to be followed are classified by the symbols: 
 
 
Symbol with white background denotes item that is PROHIBITED from doing. 
 
Symbol with dark background denotes item that must be carried out. 
 
 
Carry out test run to confirm 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. 
 
 WARNING 
1. 
Do not install Mono bloc unit near handrail of veranda. When installing Mono bloc unit at veranda of high rise building, child may climb 
up to Mono bloc unit and cross over the handrail and causing accident. 
 
2. 
Do not use unspecified cord, modified cord, join 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. 
 
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 pipe. 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.  This unit is a multi supply appliances. All circuits must be disconnected before accessing to the unit terminals. 
 
10. 
Do not modify the wiring of Mono bloc unit for installation of other components (i.e. heater, etc.). Overloaded wiring or wire connection 
points may cause electrical shock or fire. 
 
11.  Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury etc. 
 
12. 
For electrical work, follow the local national 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. 
 
13. 
For water circuit installation work, follow to relevant European and national regulations (including EN61770) and local plumbing and 
building regulation codes. 
 
14. 
Must engage an authorized dealer or specialist for installation. If installation is defective, it will cause water leakage, electrical shock or 
fire. 
 
15.  Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fire. 
 
16. 
Only use the supplied or specified installation parts. Else, it may causes Mono bloc unit vibrate, fall, water leakage, electrical shock or 
fire. 
 
17. 
Install at a flat, strong and firm location which is able to withstand the Mono bloc unit’s weight. If the location is slanting, or strength is 
not enough the set will fall and cause injury. 
 
 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 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 
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 aluminium fin, 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 with a minimum 3.0 mm contact gap. 
Power supply 1: Use approved 20A 4-poles circuit breaker. 
Power supply 2: Use approved 20A 4-poles 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.
