DO NOT BYPASS SAFETY DEVICES
Scroll equipped units should never be used to evacuate
the air conditioning system. Vacuums this low can cause
internal electrical arcing resulting in a damaged or failed
compressor.
DO NOT USE MEANS TO ACCELERATE THE DEFROSTING
PROCESS OR TO CLEAN, OTHER THAN THOSE
RECOMMENDED BY THE MANUFACTURER.
THE APPLIANCE SHALL BE STORED IN A ROOM WITHOUT
CONTINUOUSLY OPERATING IGNITION SOURCES (FOR
EXAMPLE: OPEN FLAMES, AN OPERATING GAS APPLIANCE
OR AN OPERATING ELECTRIC HEATER).
DO NOT PIERCE OR BURN.
BE AWARE THAT REFRIGERANTS MAY NOT CONTAIN AN
ODOR.
Note: This appliance is suitable for outdoor use.
Installation Clearances
Special consideration must be given to location of the con-
densing unit(s) in regard to structures, obstructions, other
units, and any/all other factors that may interfere with air
circulation. Where possible, the top of the unit should be
completely unobstructed; however, if vertical conditions
require placement beneath an obstruction there should
be a minimum of 60 inches between the top of the unit
and the obstruction(s). Ensure there is not a potential for
refrigerant to pool should a leak occur in the unit. The spec-
ified dimensions meet requirements for air circulation only.
Consult all appropriate regulatory codes prior to determining
final clearances.
Another important consideration in selecting a location for
the unit(s) is the angle to obstructions. Either side adjacent
the valves can be placed toward the structure provided the
side away from the structure maintains minimum service
clearance. Corner installations are strongly discouraged.
