In a multi zone AC system is it necessary to run both air handlers when pulling pink antifreeze through the system. I don't think raw water goes to air handlers only the condenser which services both air handlers, so is it ok to turn on just one air unit when winterizing, Thanks.

Yes, turn on any one AC. It will activate the pump and circulate to all units, assuming a single pump. You'll still need to pour pink into each of the three AC drip pans however.

I blow mine out with my compressor... I don't turn on the AC when winterizing it... It takes only about 5 minutes... I did have to install a garnden hose fitting between the strainer and pump...
