  There should not be any heat source or steam 

near the unit. 

  A place where air circulation in the room is good. 

  A place where drainage can be easily done. 

  A place where noise prevention is taken into 

consideration. 

  Do not install the unit near the door way. 

  Ensure the spaces indicated by arrows from the 

wall, ceiling, fence or other obstacles. 

  Recommended installation height for indoor unit 

shall be at least 800 mm. 

  Must install on a vertical wall. 

  When install electrical equipment at wooden 

building of metal lath or wire lath, according to 
electrical facility technical standard, no electrical 
contact between equipment and building is 
allowed. Insulator must be installed in between. 

  Do not install the unit at outdoor. This is designed 

for indoor installation only. 

  When connecting solar pump station cable 

between indoor unit and solar pump station, the 
distance between both apparatuses shall be 2 ~ 8 
meters and the maximum length of 10 meter only. 
Failure to do so may lead to abnormal operation 
to the system. 

  If an awning is built over the unit to prevent direct 

sunlight or rain, be careful that heat radiation from 
the condenser is not obstructed. 

  Avoid installations in areas where the ambient 

temperature may drop below -20°C. 

  Keep the spaces indicated by arrows from wall, 

ceiling, fence or other obstacles. 

  Do not place any obstacles which may cause a 

short circuit of the discharged air. 

  If outdoor unit installed near sea, region with high 

content of sulphur or oily location (e.g. machinery 
oil, etc), it lifespan maybe shorten. 

  When installing the product in a place where it will 

be affected by typhoon or strong wind such as 
wind blowing between buildings, including the 
rooftop of a building and a place where there is no 
building in surroundings, fix the product with an 
overturn prevention wire, etc. (Overturn prevention 
fitting model number: K-KYZP15C) 
 

 

 

  If piping length is over 10 m, additional refrigerant 

should be added as shown in the table.

For better ventilation & multiple-outdoor installation,  

please consult authorized dealer/specialist.

The centre of installation plate should be at more than 
551 mm at right and left of the wall. 
The distance from installation plate edge to ground 
should more than 1550 mm. 

  Always mount the installation plate horizontally by 

aligning the marking thread and using a level gauge. 

  Mount the installation plate on the wall with 6 sets of 

plug, bolt and washer (all non-supply) with size M8. 

 

1  Insert the piping sleeve to the hole. 
2  Fix the bushing to the sleeve. 
3  Cut the sleeve until it extrudes about 15 mm 

from the wall. 

 

When the wall is hollow, please be sure to use the sleeve for 
tube assembly to prevent dangers caused by mice biting the 
connecting cable. 

 

4  Finish by sealing the sleeve with putty or 

caulking compound at the final stage.

1  When connecting solar pump station cable 

between indoor unit and solar pump station, the 
distance between both apparatuses shall be 2 ~ 
8 meters and the maximum length of 10 meter 
only. Failure to do so may lead to abnormal 
operation to the system. 

2  Engage the slots on the indoor unit to the hooks 

of installation plate  . Ensure the hooks are 
properly seated on the installation plate by 
moving it left and right. 

3  Fix the screws   to the holes on the hooks of 

installation plate,  , as illustrated below.

  The minimum requirement of water in the system is 

30 litres. If this value could not be achieved, please 
install additional buffer tank (field supply). 

  Water inlet and water outlet in indoor unit are used 

for connection to water circuit. Please request a 
licensed technician to install this water circuit. 

  This water circuit must comply with all relevant 

European and national regulations, i.e. IEC/EN 
61770. 

  Be careful not to deform the piping with excessive 

force when doing piping connection job. 

  Use Rp 1¼" nut for both water inlet and outlet 

connection and clean all pipings with tap water 
before connecting to the indoor unit. 

  Cover the pipe end to prevent dirt and dust when 

inserting it through a wall. 

  Choose proper sealer which can withstand the 

pressures and temperatures of the system. 

  If an existing tank is to be connected to this 

indoor/outdoor unit, ensure the pipes are clean 
before water pipe installation is carried out. 

36 

  An external filter (30 mesh or more, field supplied) 

must be installed before the water inlet of the indoor 
unit (with “WATER IN” indication). 

  Refer to Diagram 4.1 for pipe connection of 

Radiator, Floor Heater, Tank Unit, Solar Pump 
Station, 3-way Valve Kit, 2-way Valve Kit and etc. 
Fail to connect the pipes appropriately might cause 
the unit malfunction.

  Be sure to use two spanners to tighten the 

connection. Tighten the nuts with torque wrench: 
117.6 N•m. 

  If non-brass metallic piping is used for installation, 

make sure to insulate the pipes to prevent galvanic 
corrosion. 

  Make sure to insulate the water circuit pipes to 

prevent reduction of heating capacity. 

  After installation, check the water leakage condition 

in connection area during test run.

Do not over tighten, over tightening cause water leakage. 



1  Please make flare after inserting flare nut 

(located at joint portion of tube assembly) onto 
the copper pipe. (In case of using long piping) 

2  Do not use pipe wrench to open refrigerant 

piping. Flare nut may be broken and cause 
leakage. Use proper spanner or ring wrench. 

3  Connect the piping: 

o

 

Align the center of piping and sufficiently 
tighten the flare nut with fingers. 

o

 

Further tighten the flare nut with torque 
wrench in specified torque as stated in the 
table.

  Use inner diameter 15 mm drain hose in the market. 

  This hose must to be installed in a continuously 

downward direction and in a frost-free environment. 

  Do not insert this hose into sewage or drain pipe 

that may generate ammonia gas, sulfuric gas, etc. 

  If necessary, use hose clamp to further tighten the 

hose at drain hose connector to prevent leakage. 

  Water will drip from this hose, therefore the outlet of 

this hose must be installed in an area where the 
outlet cannot become blocked.
