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, including this central controller, should be installed by personnel certi fi ed by Johnson Controls,
Inc. Personnel must be quali fi ed according to local, state and national building and safety codes and
regulations. Incorrect installation could cause leaks, electric shock, fi re or an explosion. In areas where
Seismic Performance requirements are speci fi ed, 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 appropriately, injuries may occur because of the falling unit.
● Use appropriate Personal Protective Equipment (PPE), such as gloves, protective goggles and electrical
protection equipment and tools suited for electrical operation purposes.
● When transporting, be careful while picking up, moving and mounting these units.
Although the central controller may be packed using plastic straps, do not use them for transporting from one
location to another. Do not stand on or put any material on the central controller.
● When installing the central controller cables to the units, 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, wire around, or jump-out any safety device or switch.
● Use only Johnson Controls recommended, provided as standardized, or replacement parts.
● Johnson Controls will not assume any liability for injuries or damage caused by not following steps outlined or
described in this manual. Unauthorized modi
fi cations to Johnson Controls products are prohibited as they…
◦ May create hazards which could result in death, serious injury or equipment damage;
◦ Will void product warranties;
◦ May invalidate product regulatory certi fi cations;
◦ May violate OSHA standards;
Take the following precautions to reduce the risk of property damage.
● Do not touch the main circuit board or electronic components in the controller or remote devices. Make sure that
dust and/or steam does not accumulate on the circuit board.
● 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 electronic interference “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. (approximately 3m) away from such devices.
● Locate the wireless controller at a distance of at least three feet (approximately 1m) between the indoor unit and
electric lighting. Otherwise, the receiver part of the unit may have dif
fi culty receiving operation commands.
