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.
IMPORTANT
Keep in store for future reference!
