Hindi po inuunat yung yero na takip ng styro, may turnilyo po sa baba ya. Tsaka dapat naka layo yung main board. Hindi binabalot na plastic dahil prone pa rin mabasa. I don't know pero ako hindi ako natuwa sa way ng pag linis. Pasensya na po sa aking opinion.

Nakaharang ba talaga sa harap ng filter yung parang battery sir? Dati kasi malinis yung harap ng aircon, walang wiring na nakalabas..

[@TelluricHelix]

Ilang oras po nilinis?

[@homeraker5474]

Mabilis naman po. Mga 1 hour or less.
