If temperatures are inadequate for charging by subcooling You must cover the equipment until you return You should charge by lineset length and return when temperatures are adequate You cannot run or add refrigerant to the equipment at all You can let the system run regardless of charge Question Title * 11. If you were choosing to size a unit to the heating load or to the cooling load, what else must you consider Only the Manual J calculation for the home How much money the customer wants to spend on accessories The ductwork limitations How many people live in the house Question Title * 12. Additional refrigerant charge is listed as 1 extra pound per 10 ft 0.6 oz/ft, but should be double checked Simply based on superheat Simply based on subcooling Question Title * 13. Questions 14-23 pertain to current Evolution Systems, do you understand Yes Question Title * 14. Communication wire from the air source to the outdoor unit uses C, D A, B, C, D A, B, and sometimes C B, D Question Title * 15. The manuals will tell you to wait 10 minutes after power down before handling the circuitry, why? Not all disconnects work correctly and powering down for 10 minutes will trip a breaker if something is wrong Since AC voltage flows both ways on a wire, you have to wait for the opposite direction to flow out The AC voltage charges capacitors at a higher voltage than your meter reads at the incoming lugs. So the capacitors need time to drain You don't, the factory is just making rules Question Title * 16. The PEV does what? Keep refrigerant pressures isolated from low to high sides Equalizes the pressures from the low and high sides Soft start the compressor Prevent the system from running when the pressures are equal Question Title * 17.
