When transporting, be careful when picking up, moving and mounting these units. Although the 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 controller.
●
When installing the controller cabling 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 shall will not assume any liability for injuries or damage caused by not following steps outlined
or described in this manual. Unauthorized modifi 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 certifi cations;
◦
May violate OSHA standards;
●
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 controller at a distance of at least 3 ft. (approximately 1m) between the indoor unit and electric
lighting. Otherwise, the receiver part of the unit may have diffi culty 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 (fi lter).
●
During the test run, check the unit's operation temperature. If the unit is used in an environment where the
temperature exceeds the operation boundary, it may cause severe damage. Check the operation temperature
boundary in the manual. If there is no specifi ed temperature, use the unit within the operation temperature
boundary of 35° to 104°F (0 to 40°C).
●
Read this installation and maintenance manual for properly electrical wiring work.
Installation Precautions
●
If the remote sensors are not used with this controller, then do not install this controller...
▫
In a room where there is no thermostat.
▫
Where the unit is exposed to direct sunshine or direct light.
▫
Where the unit will be in close proximity to a heat source.
▫
Where hot/cold air from the outdoors, or a draft from elsewhere (such as air vents, diffusers or grilles) can
affect air circulation.
▫
In areas with poor air circulation and ventilation.
●
Perform a test run using the controller to ensure normal operation. Safety guards, shields, barriers, covers, and
protective devices must be in place while the compressor/unit is operating. During the test run, keep fi ngers and
clothing away from any moving parts.
After installation work for the system has been completed, explain the "Safety Precautions," use, and maintenance
of the unit to the customer according to the information in all manuals that accompanied the system. All manuals and
warranty information must be given to the user or left near the Indoor Unit.
