Note:
- Airflow data is for dry coil conditions only, tested without filters.
- For optimal performance, external static pressures of 0.2 in. W.C. to 0.6 in. W.C. are recommended.
Applications above 0.6 in. W.C. are not recommended.

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
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.
Installation verification
Before installation, review the installation aids that follow.
During installation, use these installation aids to verify
that tasks are completed as required.
TXV checklist
□ Is the coil metering device installed correctly?
□ Is the correct TXV installed according to the
Technical
Guide
or
Tabular Data Sheet
for the outdoor section?
□ Is the TXV temperature bulb positioned correctly?
□ Is the TXV temperature bulb insulated?
□ Is the equalizer line connected?
