I am working with a portable AC unit that needs to keep a small computer room cool. If the power goes out to the building the AC will shutoff and won't comeback ON automatically.
My question is: can i bypass (jumper) the main ON/OFF switch so once the power turns back ON the AC will do as well.
Or is there a better solution?
The cost of a single central AC just for that room is way too expensive for this small start up company.

Is the on/off switch a momentary switch? If not, then leaving the switch in the on position should restart the unit when power returns.
Aside from the technical issues, do you really want to modify the equipment? I would think the LIABILITY INSURANCE would be rather significant if something did not go well.

Contact the manufacturer. There may be some sort of user menu where you can set the machine to start up after a restoration of power. The same idea but different application, as the sleep timer on a TV set.
Can the A/C be connected to a home automation system? If so, perhaps the connection point allows remote operation.
Does the A/C unit use a remote control? Perhaps the remote could be hacked?

I think Larry's first response is the only real answer for you. See what the manufacturer says. You really want to be using the approved solution. I am sure you can jumper something out to make it go but that might be outside the scope of your insurance.

Small UPS depending on how long the power is going to be off?

Actually being a AC it need a large UPS. Contact the manufacturer and see if they make an 'auto restart' kit.

I contacted the manufacturer they could not help me. The unit doesn't have an auto ON function. I think i will push them to go to a small central AC unit just for that room.
Too bad the building owner doesn't allow a wall mounted unit.
Thank you all for your replies.

Niko: You said a 'small computer room'?
Is that room a 'IT' classified room? (Article 645)
I suggest that you check into that Article. As you said a 'small start-up' company, but your building dept may have issues with that 'room'.
It all depnds on what it is 'called' and by whom.
A seperate system works in an 'IT' room by Art 645, but there qre other requirements.
