1 There was a change in many of the Main Box components at the end of 2006. The majority of the component changes occurred
in the power panel. The only components that changed in the control panel were several of the relays. See the following
page for relays used in units built 1/07 & later. If the unit was built between 10/06 & 12/06 contact Daikin McQuay Parts to
verify which controls are installed.
2 All R20 options are detailed here but for units with gas heat, the R20 is located in the gas heat control box (see section G).
