Unit has two separate breakers that are not tied or ganged
15 Amp breaker on Leg 1 (120) and a second 15 Amp breaker on Leg 2 (120).
I believe the Rheem spec for this model is 20 Amp minimum and 30 amp maximum for circuit protection.
Besides being under the minimum (15 amp) size breakers should they be tied.

Actually, it's
30-amp minimum, 35-amp-maximum. (see the attached chart I took from the spec sheet at
http://www.winmech.com/r11_834_rev2_...4_rrna2to3.pdf )
So...unit 1 breaker looks just fine. Unit 2, assuming it's exactly the same model, should have a similar 30 to 35-amp breaker...and with the handle tie (
any 240-volt circuit is a hazard without the handle tie). Even though the RLA (rated load amps) for the unit is only 15-amps, I'm really surprised that it can actually start up and function without the surge tripping the 15-amp breakers.
