Important: This Document is customer property and is to remain with this unit. Please return to service information
pack upon completion of work.
Important: These instructions do not cover all variations
in systems nor provide for every possible contingency to
be met in connection with the installation. Should further
information be desired or should particular problems
arise which are not covered sufficiently for the pur-
chaser’s purposes, the matter should be referred to your
installing dealer or local distributor.
Note: The manufacturer recommends installing ONLY
AHRI approved, matched indoor and outdoor systems.
Some of the benefits of installing approved matched
indoor and outdoor split systems are maximum efficien-
cy, optimum performance, and the best overall system
reliability.
Note: All AHRI ratings use a 90 second fan off delay.
Use your branded thermostat or separate relay to enable
this delay.
Note: Condensation may occur on the surface of the air
handler when installed in an unconditioned space. When
units are installed in unconditioned spaces, verify that
all electrical and refrigerant line penetrations on the air
handler are sealed completely.
Important: The GAF2 air handlers will only use the fol-
lowing internal electric heaters:
