I recently had a brand new Rheem 4 ton/13SEER heat pump system installed in a new house. The outside unit (compressor) is set on a concrete pad in a corner so that the side clearance is 12" on one long side, 6" on the short side, and open to the outside on the other long side. The 4th side is a solid access panel. I mentioned to the installer that it looked a little close on the 6" side, and he said it was no big deal. Also the unit has about a 2" slope from side to side... so it is not level. He also said this was close enough..? I asked for the condenser paperwork and he said it was inside the unit..? At any rate, I need some re-assurance that the clearance and out of level condenser will be OK. I don't want to buy another one for a long time. Thanks! Donbunker

Get to the paperwork for exact factory clearence requirements. Many units are different so make sure to check yours under the correct model on the paperwork.The install instructions should be left with the customer when the job is done so could be he did leave them inside the unit. If not I would contact a responsible party at the company and demand your papers because you paid for them since they came with your unit.

BTW units are to be close to level. Drainage is built in at the factory.

An install manual is located here:

Achiever by Ruud 4 Ton 13 Seer Variable Speed Air Conditioning System with Heat Pump :: Air Conditioning/Heat Pump :: AC Direct, Inc.

Page 7 has some distances. The 6" distance MIGHT be OK. Capacity will be lost if under 12". 4" is minimum.


Page 9 says: Ensure it is level.

The compressor will not get the proper lubercation if it isn't.

This may not be your model.
