WARNINGS:
» If the information in these instructions are not followed exactly, a fire or explosion
may result, causing property damage, personal injury or death.
» Installation and service must be performed by a qualified installer or service agency.
» READ THE ENTIRE MANUAL BEFORE INSTALLING OR USING THIS EQUIPMENT.
» The unit uses R-290 gas as the refrigerant. R-290 is flammable and heavier than
air. It collects first in low areas but can be circulated by the fans. If propane gas
is present or even suspected, do not allow untrained personnel to attempt to find
the cause. The propane gas used in the unit has no odor. The lack of smell does
not indicate a lack of escaped gas. If a leak is detected, immediately evacuate all
persons from the store, and contact the local fire department to advise them that
a propane leak has occurred. Do not let any persons back into the store until the
qualified service technician has arrived and that technician advises that it is safe to
return to the store. No open flames, cigarettes, or other possible sources of ignition
should be used inside or in the vicinity of the units.
» FAILURE TO ABIDE BY THIS WARNING COULD RESULT IN AN EXPLOSION,
DEATH, INJURY AND PROPERTY DAMAGE.
