 If any gas or impurities except R410A refrigerant come into the

refrigerant pipe, serious problem may occur and it may cause injury.

 Use only rated accessories and install the air conditioner with rated

equipments.

- If you dont’t use the rated accessories, the air conditioner may drop from its place, water may leak or electric shock or fire may occur.

 Ventilate your room when refrigerant gas leaks during installation.

- Toxic gas may generate when refrigerant gas contacts with heat.

 Our units must be installed in compliance with the spaces indicated in

the installation manual to ensure either accessibility from both sides or

ability to perform routine maintenance and repairs. The units’ components must be accessible and that can be disassembled in conditions of complete safety either for people or things.

For this reason, where it is not observed as indicated into the Installation Manual, the cost necessary to reach and repair the unit (in safety, as required by current regulations in force) with slings, trucks, scaolding or any other means of elevation won’t be considered in-warranty and charged to end user.

Selecting the Installation Location

Indoor Unit

 There must be no obstacles near the air inlet and outlet.

 Install the indoor unit on a ceiling that can support its weight.

 Maintain sufficient clearance around the indoor unit.

 Make sure that the water dripping from the drain hose runs away correctly and safely.

 The indoor unit must be installed in this way, that they are out of public access. (Not touchable by the users)

 After connecting a chamber, insulate the connection part between the indoor unit and the chamber

with t10 or thicker insulation. Otherwise, there can be air leak or dew from the connection part.

 Rigid wall without vibration.

 Where it is not exposed to direct sunshine.

 Where the air filter can be removed and cleaned easily.

Space requirements for installation & service



Construction Standard for Inspection Hole.

1) In case, the ceiling is textile, Inspection hole dose not need.

2) In case, the ceiling is plaster board, Inspection hole depends on Inside height of the ceiling. a. Height is more than 1m : Only “B” [Inspection for PBA] is applied. b. Height is less than 1m : Both “A” & ”B” are applied. c. “A” & ”B” are inspection holes.

Unit Depth(D)+50mm

 You must have 20mm or more space between the ceiling and the bottom of indoor unit. Otherwise, the noise from the vibration of

indoor unit may bother the user. When the ceiling is under construction, the hole for check-up must be made to take service, clean and repair the unit.

 It is possible to install the unit at an height of between 2.2~2.5m from the ground, if the unit has a duct with a well defined lenght (300mm or more), to avoid fan motor blower contact.

Indoor Unit Installation

It is recommended to install theY-joint before installing the indoor unit.

Place the pattern sheet on the ceiling at the spot where you want to install the

indoor unit.

Note

Since the diagram is made of paper, it may shrink or stretch slightly due to temperature or humidity. For this reason, before drilling the holes maintain the correct dimensions between the markings.

Insert bolt anchors, use existing ceiling supports or construct a suitable support

as shown in figure.

Install the suspension bolts depending on the ceiling type.

 Ensure that the ceiling is strong enough to support

the weight of the indoor unit. Before hanging the unit, test the strength of each attached suspension bolt.

 If the length of suspension bolt is more than 1.5m,

it is required to prevent vibration.

 If this is not possible, create an opening on the false

ceiling in order to be able to use it to perform the required operations on the indoor unit.

Screw eight nuts to the suspension bolts making space for hanging the

indoor unit.

You must install the suspension bolts more than four when installing the indoor unit.

Hang the indoor unit to the suspension bolts between two nuts.

Note

Piping must be laid and connected inside the ceiling when suspending the unit. If the ceiling is already constructed, lay the piping into position for connection to the unit before placing the unit inside the ceiling.
