Can I replace a 10 ton single circuit, AC only condensing unit with two 5 ton split systems condensers?
I have a situation where I cant replace the existing R-22 evaporator and a R22 condensing unit is not available.
I plan on running the units in tandem. What controls should I have to make this work? How can I ensure proper and equal oil return? The old unit is 230V 3phase, 5/8 LL and 1 3/8 suction line.
Any input would help.
