NSTALLING THE NDOOR 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.
NSTALLING THE NDOOR 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.
NSTALLING THE NDOOR 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 torque...
NSTALLING THE NDOOR 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.
NSTALLING THE NDOOR 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.
NSTALLING THE NDOOR Drainpipe and Drain Hose Installation Care must be taken when installing the drainpipe and drain hose for Flexible the indoor unit so that condensate water is drained correctly outside. hose Drainpipe Fix the flexible hose to the drainpipe. The connection port of the flexible hose and PVC drainpipe must be fixed with PVC adhesives.
