WARNING
This equipment must be properly earthed.
Earth lead wire shall be Yellow/Green (Y/G) in
colour and should be longer than other lead wires
as shown in the figure for electrical safety in case
of slipping.
11.3.5 Piping Insulation
1 Please carry out insulation at pipe connection portion as mentioned in Indoor/Outdoor Unit Installation
Diagram. Please wrap the insulated piping end to prevent water from going inside the piping.
2 If drain hose or connecting piping is in the room (where dew may form), please increase the insulation by
using POLY-E FOAM with thickness 1/4" (6 mm) or above.
11.3.5.1 Cutting and flaring the piping
1 Please cut using pipe cutter and then remove the burrs.
2 Remove the burrs by using reamer. If burrs are not removed, gas leakage may be caused. Turn the piping
end down to avoid the metal powder entering the pipe.
3 Please make flare after inserting the flare nut onto the copper pipes.
