A. Owner -Occupied Residential Installations: This warranty applies to heating and air conditioning units installed in owner -occupied residences and covers defects in materials and workmanship that appear under normal use and maintenance. Warranty coverage begins on the "installation date". The installation date is one of three dates depending on the circumstances of purchase: (1) For units installed in a newly constructed residence, the installation date is the date the owner purchases the residence from the builder. (2) For units installed in existing residences, the installation date is the date that the unit is originally installed. (3) If the date the owner purchases the residence from the builder or the date the unit is originally installed cannot be verified, the installation date is three months after the manufacture date noted on the unit. Registration is not required to obtain warranty coverage, but registration entitles the owner to the Registered Additional Term Warranty described in the following paragraph. If the unit is not registered, the warranty lasts for a period up to 5 YEARS (the "Initial Term Warranty"). California and Quebec residents do not need to register the product in order to get all of the rights and remedies of registered owners under this warranty, but Registered Additional Term Warranty coverage is only available to the original owner of this unit and his or her spouse. B. Non -Owner Occupied Residential Installations: This warranty applies to heating and air conditioning units installed in residences not occupied by the owner and covers defects in material and workmanship that appear under normal use and maintenance. Warranty coverage begins on the "installation date". The installation date is one of two dates: (1) The installation date is the date that the unit is originally installed. (2) If the date the unit is originally installed cannot be verified, the installation date is three months after the manufacture date. Registration is not required to obtain warranty coverage, but registration entitles the owner to the Registered Additional Term Warranty described in the following paragraph, If the unit is not registered, the warranty lasts for a period up to 5 YEARS (the "Initial Term Warranty"). C. Commercial Installations: This warranty applies to heating and air conditioning units installed in buildings other than residences and covers defects in materials and workmanship that appear under normal use and maintenance. Warranty coverage Daikin North America LLC — RA Multi -Zone Heat Pump WGS-2MXS18NMVJUA begins on the "installation date". The installation date is one of two dates: (1) The installation date is the date that the unit is originally installed (2) If the date the unit is originally installed cannot be verified, the installation date is three months after the manufacture date. The warranty lasts for a period up to 5 YEARS. 2.02 EXTENDED WARRANTY — A. Owner -Occupied Residential Installations: If the unit is properly registered online within 60 days after the installation date, an additional warranty (the "Registered Additional Term Warranty") is provided and lasts for as long as the original registered owner or his or her spouse ("registered owner") own and reside in the home in which the unit was originally installed for a period up to 12 YEARS after the installation date. To register, go to www.daikincomfort.com and click "PRODUCT Registration". Some states and provinces do not allow limitation of warranty coverage to registered owner, so the above limitation may not apply to you. Refer to the warranty certificate for complete warranty details. B. Non -Owner Occupied Residential Installations: If the unit is properly registered online within 60 days after the installation date, an additional warranty (the "Registered Additional Term Warranty") is provided and lasts for as long as the original registered owner ("registered owner") owns the residence in which the unit was originally installed, for a period up to 12 YEARS after the installation date. To register, go to www.daikincomfort.com and click "PRODUCT Registration". Neither the limited or extended warranties continue after the unit is removed from the location where it was originally installed. The replacement of a part under this warranty does not extend the warranty period. In other words, Daikin warrants a replacement part only for the period remaining in the applicable warranty that commenced on the installation date. 2.03 INSTALLATION REQUIREMENTS Installation must comply with installation manual.
