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 (propane) gas as the refrigerant.
R-290 (propane) 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
Installation &
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
