WARNING - INCORRECT HANDLING CAN RESULT IN ELECTRICAL INJURY, DEVICE MALFUNCTION AND DAMAGE
THOROUGHLY READ THE FOLLOWING SAFETY PRECAUTIONS BEFORE EACH USE OF THIS PRODUCT (THE "DEVICE").
Do not expose the device to, or immerse the device in, water. Doing so could lead to electrical shock to a person, device malfunction or
•
device damage.
Do not install the device in a bathroom, kitchen, or any room where steam could form. Condensation could develop on or around the device and
•
cause electrical shock to a person, device malfunction and device damage.
Do not install the device in a location where a gas leak could occur.
•
Do not expose the device to heat or radiation, including direct sunlight, or install the device in a location where the temperature could be greater
•
than 40°C (104°F) or less than 0°C (32°F). Doing any of these things could result in device deformation or device malfunction.
Always ensure the device is installed in an area without exposure to high frequency noise.
•
Power generators, inverters, and high-frequency or radio communication equipment may interfere with the operation of this device.
•
All electrical work should be performed by a qualitied technician and in accordance with applicable laws and the instructions outlined in this
•
manual.
Use standard wiring with the proper current capacity to avoid current leak, excessive heat, and fire.
•
Use only specified cables and wiring; securely connect each so that the terminals do not bear any weight.
•
Include slack in the power supply wiring. Tension in the wiring may cause it to excessively heat up and break, which could result in a fire.
•
Improperly connected or short-circuited cables or wiring may produce heat and cause device malfunction, device damage, and fire.
•
Capacity shortage to the power supply circuit or improper installation may result in electrical shock or fire.
•
Do not modify or alter this device or cable in any manner whatsoever.
•
3. Installation
Thermostat may be configured for use with a conventional system. For mode settings please refer to
WWW.MITSUBISHITECHINFO.CA website M & P Series Indoor Unit Function Mode Setting chart in Application / Misc section
•
Make all connections with 18 AWG thermostat wire.
•
