'For remote mounting only
tSuitable for mounting on unit chassis
SLIDE CHASSIS INTO SLEEVE — Chassis is heavy.
Portable lifting device must be used. Exercise caution
to be sure forks do not damage chassis components (such
as drain connections) while lifting and installing. Guide
chassis into sleeve on indoor side by first placing chassis
guide channels onto lower corners of sleeve. Slide chassis
into sleeve until center partition perimeter meets gasket
provided around outer edge of sleeve. Check electrical
plugs for alignment as chassis is slid into place.
tMinimum voltage Is 197 when outdoor ambient temperature exceeds
105 F
^iFiold wiring to be sized per NEC or local codes Use copper wire only
"Maximum dual element fuse size
ttThese units require 2 separate supply circuits Refer to both branch
circuit charts for complete electrical data Two-circuitfused disconnect
must be field supplied
NOTE: Dual values in this table (for example: Electric Heater Amps:
9 4/12 5) apply to 208- and 230-volt connections, respectively

A WARNING
Do not release chassis until installed and bolted
completely into sleeve as it may fall out without
