your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air
conditioner can cut fingers, 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 the power supply and use accepted lockout and tag out procedures at all
main switches.
● This unit is a 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 modifications to Johnson Controls' products are
prohibited as they…
◦ May create hazards that could result in death, serious injury or equipment damage
◦ Will void product warranties
◦ May invalidate product regulatory certifications
◦ May violate OSHA standards
Take the following precautions to reduce the risk of property damage.
●
Be careful that moisture, dust, or variant refrigerant compounds not enter the refrigerant system
during installation work. Foreign matter could damage internal components or cause blockages.
●
If air filters are required on this unit, do not operate the unit without the air filter set in place. If the air
filter is not installed, dust may accumulate and breakdown may result.
●
Do not install this unit in any place where silicon gases can coalesce. If the silicon gas molecules
attach themselves to the surface of the heat exchanger, the finned surfaces repel water. As a result,
any amount of drainage moisture condensate can overflow from the condensate pan and could run
inside of the electrical box, possibly causing electrical failures.
●
When installing the unit in a hospital or other facility where electromagnetic waves are generated from
nearby medical and/or electronic devices, be prepared for noise and electromagnetic interference
(EMI). Do not install where the waves can directly radiate into the electrical box, controller cable,
or controller. Inverters, appliances, high-frequency medical equipment, and radio communications
equipment may cause the unit to malfunction. The operation of the unit may also adversely affect
these same devices. Install the unit at least 10 ft. (3m) away from such devices.
●
When a wireless controller is used, locate at a distance of at least 3.3 ft. (1m) between the indoor unit
and electric lighting. Otherwise, the receiver part of the unit may have difficulty receiving operation
commands.
●
If the wired controller is installed in a location where electromagnetic radiation is generated, make
sure that the wired controller is shielded and cables are sleeved inside conduit tubing.
●
If there is a source of electrical interference near the power source, install noise suppression
equipment (filter).
●
Do not install the unit in any location where animals and plants can come into direct contact with the
outlet air stream. Exposure could adversely affect the animals and plants.
●
Do not install the unit with any downward slope to the side of the drain adapter. If you do, you may
have condensate water flowing back, which may cause leaks.
●
Be sure the condensate hose discharges water properly. If connected incorrectly, it may cause leaks.
●
Do not install the unit in any place where oil can seep onto the units, such as table or seating areas in
restaurants, and so forth. For these locations or social venues, use specialized units with oil-resistant
features built into them. In addition, use a specialized ceiling fan designed for restaurant use. These
specialized oil-resistant units can be ordered for such applications. However, in places where large
quantities of oil can splash onto the unit, such as a factory, even the specialized units cannot be used.
These products should not be installed in such locations.
