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.
٨When installing drain pipe, use VP-20 for the pipe goes up the closest to the unit, and
VP-25 or higher number product for farther pipes.
٨Make 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.
٨The flexible drain hose is intended to absorb a small difference at installation of the unit
or drain pipes. Intentional bending, expanding may cause the flexible hose broken and
water leakage.
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.)
٨Pay 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:
٨Make 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.
٨When 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.
٨Make 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.
3. Make sure to make descending slope of greater than 1/100 and do not make up-down bend
