Good to know
- Indoor units and line sets are sold separately: one air handler or ceiling cassette and one line set per room. Add up the indoor units' BTUs; they shouldn't go past what this condenser supports.
- Uses R-454B refrigerant, like the rest of the 5th Gen DIY line. It can't be mixed with 4th Gen (R-410A) units or line sets.
- The condenser is hardwired to a 230V circuit. Follow your local electrical code for the hookup; in most provinces that means a licensed electrician.
- Not sure what pairs with what? The System Builder matches indoor units, outdoor units and line sets for you.
