Instructing the homeowner

When the installation is complete, do the following:
• Assist the homeowner with registering
the unit warranty using the warranty card
included with the unit or (preferably) online at
www.upgproductregistration.com. It is best practice
to complete a startup sheet showing the critical
readings of the unit at the time of commissioning.
This startup sheet can be uploaded as part of the
online registration process.
• Instruct the homeowner that the indoor coil drain
pan must be inspected and cleaned regularly to
prevent odors and ensure proper drainage.
