Overview
APPLICATION RANGE
Table 1 lists the typical application ranges for the equipment cov-
ered in this document. This document contains guidance for the
mechanical and basic electrical installation for the 50LC*H pack-
aged high outdoor air system. See Fig. 1 for model number no-
menclature. See Fig. 2 and 3 for unit dimensional drawings and
for service clearance dimensions.
Additional control setup and sensor installation is required before
equipment start-up and operation can be performed. Consult the
48/50LC*H Controls, Start-up, Operation, and Troubleshooting
manual for additional instruction.
