These instructions do not cover all variations in systems or 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 
purchaser’s purposes, the matter should be referred to your installing dealer or local distributor.

Note:

 The manufacturer recommends installing only approved matched indoor and outdoor systems. All of the manufacture’s split 

systems are AHRI rated only with TXV/EEV indoor systems. Some of the benefits of installing approved matched indoor and out-

door split systems are maximum efficiency, optimum performance and the best overall system reliability.
