2 P5417054● 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 putinto operation. If these devices are improperly adjusted or tampered with in any way, a serious accidentcan 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 allmain switches.● This unit is the pressurized system. Never loosen threaded joints while the system is under pressureand never open pressurized system parts.● Johnson Controls will not assume any liability for injuries or damage caused by not following stepsoutlined or described in this manual. Unauthorized modifications to Johnson Controls products areprohibited as they…◦ May create hazards which could result in death, serious injury, equipment damage or propertydamage;◦ 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 cycle duringinstallation 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 airfilter 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 moleculesattach themselves to the surface of the heat exchanger, the finned surfaces will repel water. As aresult, any amount of drainage moisture condensate can overflow from the condensate pan and couldrun inside of the electrical box, possibly causing electrical failures.● When installing the unit in a hospital or other facility where electromagnetic waves are generatedfrom nearby medical and/or electronic devices, be prepared for noise and electronic interferenceElectromagnetic Interference (EMI). Do not install where the waves can directly radiate into theelectrical 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 unitmay also adversely affect these same devices. Install the unit at least 10 ft. (3m) away from suchdevices.● When a wireless controller is used, locate at a distance of at least 3.3 ft. (1m) between the indoorunit and electric lighting. If not, the receiver part of the unit may have difficulty receiving operationcommands.● Do not install the unit in any location where animals and plants can come into direct contact with theoutlet 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 adaptor. If you do, you mayhave condensate 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 inrestaurants, and so forth. For these locations or social venues, use specialized units with oil-resistantfeatures built into them. In addition, use a specialized ceiling fan designed for restaurant use. Thesespecialized oil-resistant units can be ordered for such applications. However, in places where largequantities 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.Installation PrecautionsTo reduce the risk of serious injury or death, the following installationprecautions must be followed.● When installing the unit into…▫ A wall: Make sure the wall is strong enough to hold the unit’s weight. It may be necessary toconstruct a strong wood or metal frame to provide added support.
