Coleman roof top heat pump
My Coleman heat pump calls for 115 volts 60 hz. It does not mention anything about amperes. What is the minimum amps required to safely run it? Will I cause damage to the unit powering it with 115 vol...

My Coleman Mach II heat pump has run OK on voltages ranging from 108 to 140 (nominal voltage for residential service in the U.S. is 120V, delivered at 60 cycles).
I don't have the manual for my Mach II heat pump handy, RV is over at storage, manuals are in it. Current Mach 15/Mach 3 Plus A/C (more recent than my 2003 model) wants 1650 watts for "standard conditions" at 115V, needs 1900 watts continuous at 103.5 V. Full load running current is specified at 15.3 amps, locked rotor (the highest you would see starting) is 63 amps.
These brief starting currents come from starting capacitor storage (so called "start kit" is standard equipment for Coleman) or as a brief voltage surge from external power lines; the needed amps get sucked out of inertial energy from the rotor in a conventional generator.
Numbers for your A/C are probably different, but in the same range. The products have not become much more efficient over the past 10-15 years, conversion to enviromentally friendly refrigerants have worked counter to improvements in compressor A/C technology (which mostly involve making the units way oversize and running at low loads)>
These A/Cs come from a company called RV Products, the Coleman name is licensed from the descendant of the original lantern company, which actually now makes nothing itself but sells a lot of licensed stuff through its outlet store in Wichita.
