CONTENTS Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock and fire. Page PRECAUTIONS...................................................................................1 INSTALLATION INFORMATION..........................................................
If the refrigerant leaks during installation, ventilate the area immediately. Toxic gas may be produced if the refrigerant comes into the place contacting with fire. There are inflammable materials or gas. There is acid or alkaline liquid evaporating. Other special conditions. The temperature of refrigerant circuit will be high, please keep the interconnection cable away from the copper tube. The appliance shall be installed in accordance with national wiring regulations.
ACCESSORIES For the following items, take special care during construction and check after installation is finished Check if the following accessories are included with your unit. 2 1 1X 3 1X 2X Tick when checked 4 2X Is the indoor unit fixed firmly? The unit may drop, vibrate or make noise. Is the gas leak test finished? It may result in insufficient cooling or heating. 1X 1X+1X 8 7 1X 6 5 Is the unit fully insulated? Condensate water may drip.
1.1 Selecting installation site - - - 1000/39.4in - 1000/39.4in Where optimum air distribution can be ensured. Where nothing blocks air passage. Where condensate water can be properly drained. Where the false ceiling is not noticeably on an incline. Where sufficient clearance for maintenance and service can be ensured. Where there is no risk of flammable gas leaking. The equipment is not intended for use in a potentially explosive atmosphere.
1.2 Make the ceiling opening needed for installation where applicable.(For existing ceilings.) - Create the ceiling opening required for installation. From the side of the opening to the casing outlet, implement the refrigerant and drain piping and wiring for remote control (unnecessary for wireless type). Refer to each piping or wiring section. - After making an opening in the ceiling, it may be necessary to reinforce ceiling beams to keep the ceiling level and to prevent it from vibrating.
1.3 4) Check if the unit is horizontally levelled. Install the indoor unit - Do not install the unit tilted. The indoor unit is equipped with a built-in drain pump and float switch. (If the unit is tilted against the direction of the condensate flow (the drain piping side is raised), the float switch may malfunction and cause water to drip.) - Check if the unit is levelled at all four corners with a water level or a water-filled vinyl tube as shown in figure below.
OUTDOOR UNIT INSTALLATION 2.1 Precautions for selecting the location 1) Choose a place solid enough to bear the weight and vibration of the unit, where the operation noise will not be amplified. 2) Choose a location where the hot air discharged from the unit or the operation noise will not cause a nuisance to the neighbours of the user. 3) Avoid places near a bedroom and the like, so that the operation noise will cause no trouble.
2.4 Outdoor unit installation 2.3 Installation guidelines Where a wall or other obstacle is in the path of outdoor unit's inlet or outlet airflow, follow the installation guidelines below. 1) Installing outdoor unit When installing the outdoor unit, refer to "Precautions for selecting the location" . For any of the below installation patterns, the wall height on the outlet side should be 47.2in / 1200mm or less.
3 INSTALL THE REFRIGERANT PIPE 3.1 Flaring the pipe end 1) Cut the pipe end with a pipe cutter. All field piping must be provided by a licensed refrigeration technician and must comply with the relevant local and national codes. 2) Remove burrs with the cut surface facing downward so that the chips do not enter the pipe. Precautions Cut exactly at right angles. Execute heat insulation work completely on both sides of the gas piping and liquid piping.
3.3 Installation of the throttle. (For some models) 5 /19 00mm 3.4 Purging air and checking gas leakage When piping work is completed, it is necessary to purge the air and check for gas leakage. .7in WARNING Do not mix any substance other than the specified refrigerant into the refrigeration cycle. When refrigerant gas leaks occur, ventilate the room as soon as possible. The specified refrigerant should always be recovered and never be released directly into the environment.
Pipe length Up to 49.2ft / 15m Run time Not less than 10 min More than 49.2ft / 15m 2) Be sure to insulate both the gas and liquid piping. Use separate thermal insulation pipes for gas and liquid refrigerant pipes. See the figure below. Not less than 15min *2. If the compound pressure gauge pointer swings back, refrigerant may have water content or a loose pipe joint may exists. Check all pipe joints and retighten nuts as needed, then repeat steps 2) through 4). Inter-unit wire Gas pipe 3.
4 CONNECT THE DRAIN PIPE 4.3 How to perform piping 4.1 Installation of drain piping 1 3 6 5 1 530/20.9in 5 4 750/29.5in 2 220/8.7in 1-1.5m 3~5ft 300/11.8in 0~75 0~3in Install the drain piping as shown in figure below and take measures against condensation. Improperly rigged piping could lead to leaks and eventually wet furniture and belongings. 1~1.
4.4 Testing of drain piping 5 After the piping work is finished, check if drainage flows smoothy. General instructions Add approximately 1L of water gradually through the air discharge outlet. Method of adding water (see the figure below) All field wiring and components must be installed by a licensed electrician and must comply with relevant European and national regulations. 106/4.2in 65/2.6in 100/3.9in Use copper wire only.
How to connect wiring Remove the control box lid of the indoor unit. Remove the cover of the outdoor unit. Follow the "Wiring diagram label" attached to the indoor unit's control box lid to wire the outdoor unit, indoor unit and the remote control. Securely fix the wires with a field supplied champ. Attach the cover of the outdoor unit.
6 INSTALLATION OF THE DECORATION PANEL - After installing the decoration panel, ensure that there is no space between the unit body and decoration panel. Otherwise air may leak through the gap and cause dewdrop. (See figure below) Detach the intake grille. - Slide the 2 grille hooks toward the middle of the decoration panel. 1 2 Mount the intake grille. 1 2 Intake grille Grille hook Ensure that the buckles at the back of the grille be properly seated in the groove of the panel.
Close the intake grille, and close the 2 grille hooks. 7 TEST OPERATION Make sure the control box lids are closed on the indoor and outdoor units. Refer to ''For the following items, take special care during construction and check after installation is finished'' on page 2. After finishing the construction of refrigerant piping, drain piping, and electric wiring, conduct test operation accordingly to protect the unit. Test operation after installing decoration panel 1 Open the gas side stop valve.
