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...
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.

Indoor Unit Installation It is recommended to install the refnet joint before installing the indoor unit. Place the pattern sheet on the ceiling at the spot where you want to install the indoor unit. Since the diagram is made of paper, it may shrink or stretch slightly due to temperature or humidity.
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: 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. Remove the pinch pipe on the pipes and connect the assembly pipes to Refrigerant oil each pipe, tightening the nuts, first manually and then with a wrench, a spanner applying the following torque.
Cutting/Flaring the Pipes Make sure that you have the required tools available (pipe cutter, reamer, flaring tool and pipe holder). 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.
Drain Hose Installation Care must be taken when installing the drain hose for the indoor unit to ensure that any condensate water is correctly drained outside. Liquid Insert the flexible hose to the drain hose port. refrigerant port Attach the drain hose to the drain hose port with an adhesive for PVC and tape to prevent water leaks, then secure the hose with Gas refrigerant port a band etc..(The band is not supplied with the air conditioner.)

Lift-up Drain piping If it is necessary to increase the height of the drain hose somewhat, install a lift-up drain piping. Connect a lift-up drain pipe top to the drain hose with an adhesive for PVC. Wrap the insulation drain with a vinyl tape. Connect the lift-up drain pipe to the indoor unit drain hose with an adhesive for PVC.
Connecting the Connection Cord The indoor unit is powered from the outdoor unit via the connection cord. Remove the screw on the electrical component box and remove the cover plate. Route the connection cord through the side of the indoor unit and connect the cable to terminals;...
Assigning Address to Indoor Unit Before installing the indoor unit, assign an address to the indoor unit according to the air conditioning system plan. The address of the indoor unit is assigned by adjusting MAIN(SW02) and RMC(SW01) rotary switches. K1 K2 K3 K4 K5 K6 K7 K8 K9 K10 K11 K12 SW03...

Bio-pure Filter Installation (optional) The air conditioner can be fitted with a Bio-Pure or deodorizing filter to remove minute dust particles or odours. The service life of the filter is approximately three months depending on the time during which the air conditioner is used. Accessories Deodorizing Bio-pure filter...
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. LED Display on the indoor unit LED Display Indicators Abnormal conditions...
