applyadditionalinsulation.
● Payattentiontothefollowingpointswhenthe
CH-Boxisinstalledinahospitalorotherfacility
wherethereareelectronicwavesfrommedical
equipment.
(A) DonotinstalltheCH-Boxwherethe
electromagneticwaveisdirectlyradiatedto
theelectricalboxorcommunicationcable.
(B) InstalltheCH-Boxandcomponentsasfar
aspracticableoratleast3m(10ft)fromthe
electromagneticwaveradiator.
(C) Installanoiselterwhenthepowersupply
emitsharmfulnoises.
● Ensuretheinstallationplaceisconvenient
fortherefrigerantpipingorelectricalwiring
