I have this same AC the problem i faced with it was no proper cooling....so the ac technician upon inspection advised me to cut the frame grill at the back as the hot air was properly being circulated because of the enclosed frame at the back....then i cut out the back side of the frame with angle grinder cutter and the whole condensor unit was visible....after that the ac worked very well no problem till now....and now in the new models of o genral ac the back side grill which was fully covered has been removed by the company and is exposed to open for better hot air circulation at the back side of the ac 👍
