bafeboards.

Note:

Itis advisable to make a piping loopnear outdoor unit so as to reduce

vibrationtransmittedfromthere.

Note:

Whenoperatingtheairconditionerinlowoutsidetemperature,besure

tofollowtheinstructionsdescribedbelow.

• Neverinstalltheoutdoorunitinaplacewhereitsairinlet/outletside

maybeexposeddirectlytowind.

• Topreventexposuretowind,installtheoutdoorunitwithitsairinlet

sidefacingthewall.

•

Topreventexposuretowind,itisrecommendedtoinstallabafe

boardontheairoutletsideoftheoutdoorunit.

Avoidthefollowingplacesforinstallationwhereairconditionertrouble

isliabletooccur.

• Whereammablegascouldleak.

• Wherethereismuchmachineoil.
