Features & Benefits Wind-Free Cooling with Micro holes The Wind Free Air conditioner pushes air out through more, micro holes in the panel, producing a dispersed and gentle flow of air actually defined as still air and the key here is all of those holes create a still, cooled air flow that infiltrates the room gently and softly. Still Air condition : According to ASHRAE, If velocity of wind is lower than.1m/s, People can not detect wind. And they define that condition is Still Air 3

Installation Step 1 Optional: Insulating the body of the indoor unit If you install a cassette type indoor unit on the ceiling when temperature is over 27 C and humidity is over 8%, you must apply an extra mm thick polyethylene insulation or a similar type of insulation to the body of the indoor unit. 2 Install the suspension bolts, depending on the ceiling type. Ceiling support Cut away the part where pipes are pulled out for the insulating work. D A Insulate the end of the pipe and some curved area by using separate insulator. Step 2 Installing the indoor unit 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, be sure to maintain the correct dimensions between the markings. 1 Insert bolt anchors, use existing ceiling supports or construct a suitable support as shown in figure. E B C CAUTION Make sure 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 the suspension bolt is more than 1. m, you are required to prevent vibration. 3 Screw eight pairs of nuts and washers to the suspension bolts, making space for hanging the indoor unit. CAUTION You must install all of the suspension rods. It is important to leave sufficient space in the false ceiling to allow access for maintenance or repairs to the drainage pipe connection, the refrigerant pipe connection, or to remove the unit if necessary. Concrete Hole in anchor Hole in plug Insert 8

Installation Step 3 Insulating the refrigerant pipes Once you have checked that there are no leaks in the system, you can insulate the piping and hose. 1 To avoid condensation problems, place Acrylonitrile Butadien Rubber separately around each refrigerant pipe. No gap CAUTION Must fit tightly against body without any gap. Make sure that all refrigerant connection must be accessible for easy maintenance and detachment. Install the insulation not to get wider and use the adhesives on the connection part of it to prevent moisture from entering. Wind the refrigerant pipe with insulation tape if it is exposed to outside sunlight. Install the refrigerant pipe respecting that the insulation does not get thinner on the bent part or hanger of pipe. Add the additional insulation if the insulation plate gets thinner. NBR NOTE Additional insulation Hanger Always make the seam of pipes face upwards. CAUTION The insulation has to be produced in full compliance wirh European regulation EEC / EU 37 / requiring the use of sheaths insulation without using CFC and HCFC gases for health and the environment. 2 Wind insulating tape around the pipes and drain hose avoiding compressing the insulation too much. Indoor unit Insulation cover pipe Insulation pipe a x 3 Select the insulation of the refrigerant pipe. a Refrigerant pipe insulation Insulate the gas side and liquid side pipe, noting the insulation thickness that must differ according to the pipe size. Standard: Less than an indoor temperature of C, with humidity at 8%. If installing in a high humidity environment, use one grade thicker insulator by referring to the table below. If installing in an unfavourable environment, use thicker one. The heat-resistance temperature of the insulator must be more than 1 C. Be sure to overlap the insulation. CAUTION Be sure to wrap insulation tightly without any gaps. 3 Finish wrapping insulating tape around the rest of the pipes leading to the outdoor unit. 4 The pipes and electrical cables connecting the indoor unit with the outdoor unit must be fixed to the wall with suitable ducts. 9

For example, pipes installed at a corridor of a dormitory and studio or near an exit that opens and closes frequently. Places (where the pipes are installed) that are highly humid due to a lack of ventilation. Step 4 Installing the drain hose and drain pipe 1 Push the supplied drain hose as far as possible over the drain socket. 2 Tighten the metal clamp as shown in the picture. 3 Wrap the supplied large sealing pad over the metal clamp and drain hose to insulate and fix it with clamps. 4 Insulate the complete drain piping inside the building (field supply). If the drain hose cannot be sufficiently set on a slope, fit the hose with drain raising piping (field supply). Push the drain hose up to insulation when connecting the drain hose to drain socket. Metal clamp Large seailng pad Drain socket Drain hose Drain pipe Be sure to bond the drain hose and the main pipe. Refrigerant pipe before EEV kit and MCU or without EEV kit and MCU You can contact the gas side and liquid side pipes but the pipes should not be pressed. Drain hose PVC Tube Joint + VP2 (OD: 32 mm, ID: 2 mm) When contacting the gas side and liquid side pipe, use 1 grade thicker insulator. Refrigerant pipe after EEV kit and MCU Install the gas side and liquid side pipes, leave mm of space. Drain pipe When contacting the gas side and liquid side pipe, use 1 grade thicker insulator. CAUTION Check that the indoor unit is level with the ceiling by using the leveller.

Installation Install air ventilation to drain condensation smoothly. Install horizontally. Air ventilation Be horizontal Indoor unit Ceiling Flexible hose If it is necessary to increase the height of the drain pipe, install the drain pipe straight within mm from the drain hose port. If it is raised higher than mm, there may be water leaks. Max. allowable axis gap. mm or more Drain hose Band joint 1/ or more Indoor unit mm or less mm or less Ceiling Max. mm Do not give the hose an upward gradient beyond the connection port. This will cause water to flow backwards when the unit is stopped, resulting in water leaks. Max. allowable bending angle. Under gradient Indoor unit Ceiling Do not apply force to the piping on the unit side when connecting the drain hose. The hose should not be allowed to hang loose from its connection to the unit. Fasten the hose to a wall, frame or other support as close to the unit as possible. NOTE If a concentrated drain pipe is installed, refer to the figure below.

Installation Hanger 1~1.m Main air vent Individual air vent mm or more to mm Main drainpipe Centralized horizontal drainpipe (more than 1/ slope) If 3 or more units are installed, install the main air vent at the front of the farthest indoor unit from the main drain pipe. To prevent water from flowing back to indoor units, install an individual air vent at the top of each indoor unit. The air vents should be T or 7 shaped to prevent dust or foreign substances from entering. You may not need to install air vent if the horizontal drain pipe is in proper slope.
