R-32 Information (R-32 Units Only)
WARNING
This unit contains R-32, a class A2L refrigerant
that is ammable. This unit should only be
installed, serviced, repaired, and disposed of
by qualied personnel licensed or certied in
their jurisdiction to work with R-32 refrigerant.
Installation and maintenance must be done in
accordance with this manual. Improper handling
of this equipment can cause equipment damage
or personal injury.
Be aware that R-32 refrigerant may not contain an odor. Place in a well
ventilated area to prevent accumulation of refrigerant. Excessive refrigerant
leaks, in the event of an accident in a closed ambient space, can lead to
oxygen deciency.
Do not pierce or burn this unit.
Never use an open ame during service or repair. Never store in a room
with continuously operating ignition sources (for example: open ames, an
operating gas appliance, or and operating electric heater), where there is
ignitable dust suspension in the air, or where volatile ammables such as
thinner or gasoline are handled.
Only use pipes, nuts, and tools intended for exclusive use with R-32
refrigerant in compliance with national codes (ASHRAE15 or IRC).
Do not mix air or gas other than R-32 in the refrigerant system. If air enters
the refrigerant system, an excessively high pressure results, which may
cause equipment damage or injury.
For more information, consult “R-32 Guidelines (R-32 Units Only)” on page
87.
WARNING
When moving ammable A2L refrigerant to/from the unit from an auxiliary
tank, a grounding strap must be used. An electrical charge builds when
halo-carbon refrigerant travels in a rubber hose. A grounding strap must be
used between the auxiliary refrigerant tank and the unit’s end sheet (earth
ground), which will safely take the charge to the ground. A re risk could
occur if this procedure is not followed.
