Daikin FVXS25FV1B [9/18] Flaring the pipe end
7 ■English
Indoor Unit Installation (1)
4-2. Installation
• Secure using 6 screws for floor installations. (Do not forget to secure to the rear wall.)
• For wall installations, secure the mounting plate using 5 screws and the indoor unit using 4 screws.
• The mounting plate should be installed on a wall which can support the weight of the indoor unit.
1) Temporarily secure the mounting plate to the wall, make sure that the panel is completely level, and mark the boring
points on the wall.
2) Secure the mounting plate to the wall with screws.
3) Once refrigerant piping and drain piping connections are complete, fill in the gap of the through hole with putty.
A gap can lead to condensation on the refrigerant pipe, and drain pipe, and the entry of insects into the pipes.
4) Attach the front panel and front grille in their original positions once all connections are complete.
5.
Flaring the pipe end
1) Cut the pipe end with a pipe cutter.
2) Remove burrs with the cut surface facing downward so that the chips do not enter the pipe.
3) Fit the flare nut on the pipe.
4) Flare the pipe.
5) Check that the flaring is properly made.
WARNING
1) Do not use mineral oil on flared part.
2) Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.
3) Never use piping which has been used for previous installations. Only use parts which are delivered with the unit.
4) Do never install a drier to this R410A unit in order to guarantee its lifetime.
5) The drying material may dissolve and damage the system.
6) Incomplete flaring may cause refrigerant gas leakage.
