EZ Series WM
Islandaire “The Perfect Fit” units are designed to exactly replace the original, existing chassis! No field modification kits or builder renovations are required. Islandaire units are designed for optimal efficiency and reliability. This unit has the ability to have the piping and the controls “reversed” in the field. If you order the wrong side for piping and controls, no problem. Just reverse them in the field saving time and money. This appliance is intended for new construction or replacement of McQuay and Singer water source heat pumps. Please confirm that the electrical rating of this appliance matches the electrical supply available before beginning installation.
