When re-using the existing pipe system for R22 or R407C, pay attention to the following items. ž Change the flare nuts with the attached ones (JIS category 2), and reprocess the flare parts. ž Do not use thin-walled pipes. l Use phosphorus deoxidized copper alloy seamless pipe (C1220T specified in JIS H3300) for refrigeration pipe installation. In addition, make sure there is no damage both inside and outside of the pipe, and no harmful substances such as sulfur, oxide, dust or a contaminant stuck on the pipes. l Do not use any refrigerant other than R410A. Using other refrigerant except R410A (R22 etc.) may degrade inside refrigeration oil. And air getting into refrigeration circuit may cause over-pressure and resultant it may result in bursting, etc. l Store the copper pipes indoors and seal the both end of them until they are brazed in order to avoid any dust, dirt or water getting into pipe. Otherwise it will cause degradation of refrigeration oil and compressor breakdown, etc. l Use special tools for R410 refrigerant. Metal plate 10mm 2. Prepare a joint for connecting VP-20 pipe, adhere and connect the joint to the drain hose (the end made of rigid PVC), and adhere and connect VP-20 pipe (prepare on site). As for drain pipe, apply VP-20 made of rigid PVC which is on the market. l Make sure that the adhesive will not get into the supplied drain hose. It may cause the flexible part broken after the adhesive is dried up and gets rigid. l Do not bend or make an excess offset on the drain hose as shown in the picture. Bend or excess offset will cause drain leakage. Over 20mm Work procedure 1. Remove the flare nut and blind flanges on the pipe of the indoor unit. Make sure to loosen the flare nut with holding the nut on pipe side with a spanner and giving torque to the nut with another spanner in order to avoid unexpected stress to the copper pipe, and then remove them. (Gas may come out at this time, but it is not abnormal.) l Pay attention whether the flare nut pops out. (as the indoor unit is sometimes pressured.) 2. Make a flare on liquid pipe and gas pipe, and connect the refrigeration pipes on the indoor unit. Bend the pipe with as big radius as possible and do not bend the pipe repeatedly. In addition, do not twist and crush the pipes. Do a flare connection as follows: l Make sure to loosen the flare nut with holding the nut on pipe side with a spanner and giving torque to the nut with another spanner in order to avoid unexpected stress to the copper pipe, and then remove them. l When fastening the flare nut, align the refrigeration pipe with the center of flare nut, screw the nut for 3-4 times by hand and then tighten it by spanner with the specified torque mentioned in the table below. Make sure to hold the pipe on the indoor unit securely by a spanner when tightening the nut in order to avoid unexpected stress on the copper pipe. 3. Cover the flare connection part of the indoor unit with attached insulation material after a gas leakage inspection, and tighten both ends with attached straps. l Make sure to insulate both gas pipes and liquid pipes completely. Incomplete insulation may cause dew condensation or water dropping. 4. Refrigerant is charged in the outdoor unit. As for the additional refrigerant charge for the indoor unit and piping, refer to the installation manual attached to the outdoor unit.

Make sure to make descending slope of greater than 1/100 and do not make up-down bend and/or trap in the midway. l Pay attention not to give stress on the pipe on the indoor unit side, and support and fix the pipe as close place to the unit as possible when connecting the drain pipe. l Do not set up air vent. 1.5m ~ 2m Supporting metal No bump No trap Air vent Trapped air will generate noises. Not touching the water Insulation material Descending slope greater than 1/100 l When sharing a drain pipe for more than one unit, lay the main pipe 100mm below the drain outlet of the unit. In addition, select VP-30 or bigger size for main drain pipe. As wide as possible (about100mm) VP-30 or bigger Descending stop greater than 1/100 4. Insulate the drain pipe. l Be sure to insulate the drain socket and rigid PVC pipe installed indoors otherwise it may cause dew condensation and water leakage. After drainage test implementation, cover the drain socket part with pipe cover (small size), then use the pipe cover (big size) to cover the pipe cover (small size), clamps and part of the drain hose, and fix and wrap it with tapes to wrap and make joint part gapless. Drain up The thickness of insulation should be 20mm or more. l The position for drain pipe outlet can be raised up to 600mm above the ceiling. Use elbows for installation to avoid obstacles inside ceiling. If the horizontal drain pipe is too long before vertical pipe, the backflow of water will increase when the unit is stopped, and it may cause overflow of water from the drain pan on the indoor unit. In order to avoid overflow, keep the horizontal pipe length and offset of the pipe within the limit shown in the figure below. ⑥ Drain pipe Caution l Install the drain pipe according to the installation manual in order to drain properly. Imperfection in draining may cause flood indoors and wetting the household goods，etc. l Do not put the drain pipe directly into the ditch where toxic gas such as sulfur, the other harmful and inflammable gas is generated. Toxic gas would flow into the room and it would cause serious damage to user’s health and safety (some poisoning or deficiency of oxygen). In addition, it may cause corrosion of heat exchanger and bad smell. l Connect the pipe securely to avoid water leakage from the joint. l Insulate the pipe properly to avoid condensation drop. l Check if the water can flow out properly from both the drain outlet on the indoor unit and the end of the drain pipe after installation. l Make sure to make descending slope of greater than 1/100 and do not make up-down bend and/or trap in the midway. In addition, do not put air vent on the drain pipe. Check if water is drained out properly from the pipe during commissioning. Also, keep sufficient space for inspection and maintenance. - 295 to 325mm Drain hose 100 or less 600mm or less Pipe diameter f 6.35 f 9.52 f 12.7 f 15.88 f 19.05 l After i leakag l Do dr l For ne hangi 1.
