serious injury.
Indicates a hazardous situation that, if not avoided, could result in minor or moderate
injury.
Indicates information considered important, but not hazard-related (for example,
messages relating to property damage).
General Precautions
To reduce the risk of serious injury or death, read these instructions thoroughly
and follow all warnings or cautions included in all manuals that accompanied the
product and are attached to the unit. Refer back to these safety instructions as
needed.
● This system should be installed by personnel certied by Johnson Controls, Inc. Personnel must be qualied
according to local, state and national building and safety codes and regulations. Incorrect installation could
cause leaks, electric shock, re or explosion. In areas where Seismic ‘’Performance requirements are
specied, the appropriate measures should be taken during installation to guard against possible damage
or injury that might occur in an earthquake. If the unit is not installed correctly, injuries may occur due to a
falling unit.
P5417055
1
● Use appropriate Personal Protective Equipment (PPE), such as gloves and protective goggles and, where
appropriate, have a gas mask nearby. Also use electrical protection equipment and tools suited for electrical
operation purposes. Keep a wet cloth and a re extinguisher nearby during brazing. Use care in handling,
rigging, and setting of bulky equipment
.
● When transporting, be careful when picking up, moving and mounting these units. Although the unit may
be packed using plastic straps, do not use them for transporting the unit from one location to another. Do
not stand on or put any material on the unit. Get a partner to help, and bend with your knees when lifting
to reduce strain on your back. Sharp edges or thin aluminum ns on the air conditioner can cut ngers, so
wear protective gloves.
● Do not touch or adjust any safety devices inside the indoor or outdoor units. All safety features,
disengagement, and interlocks must be in place and functioning correctly before the equipment is put into
operation. If these devices are improperly adjusted or tampered with in any way, a serious accident can
occur. Never bypass or jump-out any safety device or switch.
● Before servicing, turn-OFF current at the power source and use accepted lockout and tag out procedures
at all main switches.
● This unit is the pressurized system. Never loosen threaded joints while the system is under pressure and
never open pressurized system parts.
● Johnson Controls will not assume any liability for injuries or damage caused by not following steps outlined
or described in this manual. Unauthorized modications to Johnson Controls products are prohibited as

Operation
NOTICE
● Do not insert ngers or objects into air inlet/outlet. Injury can result from rotating fan blades or energized
electrical components.
● Do not touch the wired controller with wet hands. Failure of the wired controller or an electrical shock can
result.
● Hair spray, insecticides, lacquers, and other pressurized substances should not be used within 3.3ft (1m)
of any air conditioning unit. They can react with energized electrical components and cause re.
● Do not install the indoor unit anywhere discharge airow can pass directly toward nearby heating
equipment (space heaters). It may interfere with the combustion process in these units.
● When the indoor unit is operating with heating equipment, ventilate a room sufciently. Any leaked
refrigerant gas that happens to come into contact with any heat source can become toxic on contact and
can cause suffocation in the immediate area.
● Shut down at the main power source if the GFCI (Ground Fault Circuit Interrupter) activates frequently.
Contact your distributor or contractor immediately. Failure to act accordingly can result in serious injury
and damage to the unit.
● CAUTION! If you smell anything burning, shut down the unit and turn OFF the power at the main power
source. Contact the re department and your installer or electrical contractor.
● Make sure that a test for leakage of refrigerant gases has been performed. The refrigerant used for this
unit (HFC R410A) is a non-ammable, non-toxic, and odorless gas. However if refrigerant should leak
and make contact with sparks, re will erupt and generate toxic gas. Also, the uorocarbon, which is
heavier than air will cover the oor surface and can cause suffocation.
● If uorocarbon gas should leak, turn OFF all heating equipment and ventilate the room immediately. Mop
down or vacuum oor areas of residual toxic particulate.
● CAUTION! Do not operate indoor units with the electrical box and switch panel open and exposed.
Incidental contact with energized electrical components can prove fatal.
● Air circulation should be optimized to achieve the best distribution pattern and not settled into isolated
pockets that can make people uncomfortable.

Repair / Relocation
NOTICE
● When the air conditioner is to be repaired or transported to a new location, contact your distributor or
contractor. If the repair and the installation are not completed, electric shock or re can result.
Others
● Turn OFF all power at the main power source before performing maintenance work. Failure to do so can
result in damage to internal components with severe or fatal electrical shock.
● Insulate all electrical components and connections from exposure to moisture. Failure to do so can result
in an electrical short, or re.
● Do not tamper with or attempt to "repair" electrical wiring or connections. Call your installer or electrical
contractor. Serious or fatal injury can occur.
● Perform all maintenance work on a rm and stable platform to minimize the risk of injury.
● Do not attempt to "clean" indoor unit components with liquid or powdered cleaning agents during
maintenance. Electric shock, sparks, ame, and serious or fatal injury can occur.
● System piping is charged with refrigerant and highly pressurized.
● Hold the air lter and the air inlet grille securely when attaching or removing it. Carelessness can result in
accident or injury.
● When cleaning the lens surface of the motion sensor, do not make unnecessary contact as the lens can
be easily scratched.

3. Before Operation
NOTICE
Apply power to the outdoor unit(s) at least 12 hours prior to system operation to allow for preheating
of the compressor oil. Do not start the system immediately without preheating the compressor.
Otherwise, the compressor can be damaged. Check that the outdoor unit is free of ice and snow
cover. If snow covered, remove with hot water at (122°F or 50°C). If hot water temperature is higher
than 122oF (50oC), it can cause damage to plastic parts.
● When the system is restarted after a shutdown longer than approximately three months, it is recommended
that the system be checked by your service contractor.
● Turn OFF at the main switch when the system has been off for a long period of time.
If the main switch is not turned OFF, electricity is consumed, because the oil heater is always energized
during periods of compressor stoppage.
