Preparation for Installation When deciding on the location of the air conditioner with the owner, the following restrictions must be taken into account. General Do NOT install the air conditioner in a location where it will come into contact with the following elements: ◆ ◆ ◆ ◆ ◆ Combustible gases Saline air Machine oil Sulphide gas Special environmental conditions If you must install the unit in such conditions, first consult your dealer.
ENGLISH Deciding on Where to Install the Indoor Unit 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.

Indoor Unit Installation It is recommended to install the refnet joint before installing the indoor unit. 1 Place the pattern sheet on the ceiling at the spot where you want to install the indoor unit. Note Concrete 2 Insert bolt anchors, use existing ceiling supports or construct a suitable support as shown in figure. 3 Install the suspension bolts depending on the ceiling type.
ENGLISH Purging the unit On delivery, the indoor unit is loaded with refrigerant gas. All this gas must therefore be purged before connecting the assembly piping. To purge the inert gas, proceed as follows. Unscrew the pinch pipe at the end of each refrigerant pipe. Result: Note All inert gas escapes from the indoor unit.
Connecting the Refrigerant Pipe There are two refrigerant pipes of differing diameters: ◆ A smaller one for the liquid refrigerant ◆ A larger one for the gas refrigerant ◆ The inside of copper pipe must be clean & has no dust. 1 Refrigerant oil Remove the pinch pipe on the pipes and connect the assembly pipes to each pipe, tightening the nuts, first manually and then with a torque wrench, a spanner applying the following torque. Outer Diameter 6.35 mm (1/4") 9.52 mm (3/8") 12.70 mm (1/2") 15.
ENGLISH Cutting/Flaring the Pipes 1 Make sure that you have the required tools available (pipe cutter, reamer, flaring tool and pipe holder). 2 If you wish to shorten the pipes, cut it with a pipe cutter, taking care to ensure that the cut edge remains at a 90° angle with the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly.
Performing Leak Test & Insulation Leak Test To check for gas leaks on the indoor unit, check the connection part of each refrigerant pipe by using a leak detector. Insulation Once you have checked that there are no leaks in the system, you can insulate the piping and hose. 1 No gap To avoid condensation problems, place T13.0 or thicker Acrylonitrile Butadien Rubber around each refrigerant pipe. Note ◆ Always make the seam of pipes face upwards. NBR(T13.
ENGLISH Drainpipe and Drain Hose Installation Care must be taken when installing the drainpipe and drain hose for the indoor unit so that condensate water is drained correctly outside. 1 Fix the flexible hose to the drainpipe. ◆ The connection port of the flexible hose and PVC drainpipe must be fixed with PVC adhesives. ◆ Check out that the connected part doesn’t leak. 2 Connect the flexible hose to the flexible hose port. ◆ Make sure that a rubber ring is installed on the drain hose port.
Drain Hose Installation (cont.) Note ◆ If a concentrated drain hose is installed, refer to the figure below. Drain clamp 1/100 or more slope 100mm or more Air ventilation Concentrated drain hose Testing the drainage You should test the drainage after completing the installation. Prepare a little water about 2.0 liters. 1 Turn the cover drain pump, then pull it out. 2 Pour water into the indoor unit as shown in figure.
ENGLISH Connecting the Connection Cord The indoor unit is powered from the outdoor unit via the connection cord. 1 Remove the screw on the electrical component box and remove the cover plate. 2 Route the connection cord through the side of the indoor unit and connect the cable to terminals; refer to the figure below. 3 Route the other end of the cable to the outdoor unit through the ceiling & the hole on the wall. 4 Reassemble the electrical component box cover, carefully tightening the screw.
Assigning Address to Indoor Unit 1 Before installing the indoor unit, assign an address to the indoor unit according to the air conditioning system plan. 2 The address of the indoor unit is assigned by adjusting MAIN(SW01, SW02) and RMC(SW03) rotary switches. K1 K2 K3 K4 SW04 K5 K6 K7 K8 SW05 K9 K10 SW06 SW01 SW02 RMC SW03 Setting Main Address ◆ The MAIN address is for communication between the indoor unit and the outdoor unit. Therefore, you must set it to operate the air conditioner properly.
ENGLISH Additional Functions Increasing fan speed ◆ If external static pressure is too great, the air flow volume may drop too low at each air outlet. This problem can be solved by increasing the fan speed. Switch No. Switch ON Switch OFF K3 Normal fan speed High fan speed K1 K2 K3 K4 SW04 Compensation for lost temperature in heating operation ◆ Reduces the difference between an actual room temperature and a sensed temperature by the air conditioner when heating. Switch No.
Bio-pure Filter installation (optional) The air conditioner can be fitted with a Bio-Pure filter to remove minute dust particles. The service life of the filter is approximately three months depending on the time during which the air conditioner is used. Accessories 1 Bio-pure filter M4x10 tapped Screw 1 4 Remove the vinyl packing from the filter. Note E-18 Do not remove the packing from a bio-pure filter until you wish to use the filter, as it will lose its properties.
ENGLISH Troubleshooting Detection of errors ◆ If an error occurs during the operation, an LED flickers and the operation is stopped except the LED. ◆ If you re-operate the air conditioner, it operates normally at first, then detect an error again.
Troubleshooting (cont.) LED Display Indicators Abnormal conditions Operating Self-diagnostic error (including the indoor unit not detected) Displayed on appropriate indoor unit which is operating Displayed on outdoor unit 1. Error of electronic expansion valve close 2. Error of electronic expansion valve open X X 3. Breakaway of EVA OUT sensor 4. Breakaway of EVA IN sensor 5. Breakaway of COND MID sensor Displayed on appropriate indoor unit which is operating Displayed on outdoor unit 6.
ENGLISH Wired remote controller ◆ If an error occurs, is displayed on the wired remote controller. ◆ If you would like to see an error code, press the Test button.
