The unit must be installed according to the instructions in order to minimize the risk of damages by earthquakes,
typhoons or strong winds. An improperly installed unit may fall down and cause damages or injuries. The unit must
be securely installed on a structure that can sustain its weight. If the unit is mounted on an unstable structure, it
may fall down and cause damage or injury.
All electric work must be performed by a qualified electrician according to local regulations and the instructions
given in this manual. The units must be powered by dedicated power lines and the correct voltage and circuit
breakers must be used. Power lines with insufficient capacity or incorrect electrical work may results in electric
shock or fire. Only the specified cables can be used for wiring, Connections must be made securely without tension
on the terminals. If cables are connected or installed improperly, it may result in overheating or fire. Terminal block
cover panel of the outdoor unit must be firmly fixed. If the cover panel is mounted improperly, dust and moisture
may enter the unit, and it may cause electric shock or fire. Make sure to use accessories authorized by Mitsubishi
Electric and ask an installer or authorized electrician to install them. If accessories are improperly installed, it may

an installer or an authorized electrician.
After installation has been completed, make sure that refrigerant does not leak. If refrigerant leaks and comes into
contact with a flame, poisonous gases will be released.
Use clean water which meets water quality standards. The deterioration of water quality may result in the system
breakdown or water leakage.
Never use anything other than water as a medium. It may cause a fire or an explosion.
Do not use heated water that is produced by the heat pump directly for drinking or cooking. There is a risk to
damage your health. There is also a risk that installing the water heat exchanger may corrode if the necessary water
quality for the air to water heat pump system cannot be maintained. If you wish to use the heated or cooled water
from the heat pump for these purposes, take measures such as to isolate the second heat exchanger within the
water piping system.
BEFORE INSTALLATION CAUTION:
Do not use the unit in an unusual environment. If the heat pump is installed exposed to steam, volatile oil (including
machine oil), sulphuric gas, exposed to briny air, or covered with snow, the performance can be significantly
reduced and the internal parts can be damaged.
