Thepressureresistanceofthecharginghosehasbeen
raisedtomatchthehigherpressureofR410A.Thehose
materialhasalsobeenchangedtosuitHFCuse,and
thesizeofthefittinghasbeenchangedtomatchthe

6.Vacuumpumpadaptor
WhenusingavacuumpumpforR410A,itisnecessary
toinstallanelectromagneticvalvetopreventthe
vacuumpumpoilfromflowingbackintothecharging
hose.Thevacuumpumpadaptorisinstalledforthat
purpose.ifthevacuumpumpoil(mineraloil)becomes
mixedwithR410A,itwilldamagetheunit.

Theleakdetectorandhalidetorchthatwereusedwith
CFCandHCFCcannotbeusedwithR410A(because
thereisnochlorineintherefrigerant).
