To ensure the deliv ery of purer and healthie r water, a micro-pro cesso r is insta lled in the
purif ier that perf orms the following functi ons:-
UV Sta biliza tion D elay: T o ensur e that the UV lamp is pre-h eated a nd is w orking at its
optim um before it st arts disi nfecti ng water, th e contro ller prov ides a two seco nd delay
to UV lamp when a purifie r is switched on. Duri ng this perio d, only UV lamp is on and all
other electr ical devices of purifier are switched off and no water flows through.
Purif icatio n Delay : To en sure th at the w ater l ying id le in t he inte rnal pi pes an d the UV
chamb er is thorou ghly disinfe cted before being pass ed onto the storag e tank, the
syste m provide s approxi matel y 5 seconds Pur ificat ion Dela y when the pur ifier is
switc hed on. Du ring thi s period , all ele ctrica l device s except U V lamp ar e switch ed off
and UV lamp kills the micro-org anisms presen t in water inside the UV chamber . After this
delay , a ll other electric al device s s uch as sole noid valve etc., get a ctivat ed and the
