Indicates important instructions.
Indicates a parts that requires grounding.
Indicates that caution must be taken with rotating parts. (This symbol is on the main unit label.) <Color: Yellow>
Indicates that the parts that are marked with this symbol pose a risk of electric shock. (This symbol is on the main
unit label.) <Color: Yellow>
WARNING
Carefully read the labels affixed to the main unit.
WARNING
Do not use refrigerant other than the type indicated in the
manuals provided with the unit and on the nameplate.

Precautions for handling units for use with water
WARNING
Have all electrical work performed by an authorized electri-
cian according to the local regulations and the instructions
in this manual. Use a dedicated circuit.
Insufficient power supply capacity or improper installation
of the unit may result in malfunctions of the unit, electric
shock, or fire.
Keep electrical parts away from water.
Wet electrical parts pose a risk of electric shock, smoke, or
fire.
Securely attach the control box cover.
If the cover is not installed properly, dust or water may infil-
trate and pose a risk of electric shock, smoke, or fire.
Only use the type of water that is indicated on the unit when
installing or relocating the unit.
Infiltration of any other types of refrigerant or air into the unit
may adversely affect the refrigerant cycle and may cause
the pipes to burst or explode.
Consult your dealer or a qualified technician when moving
or reinstalling the unit.
Improper installation may result in water leakage, electric
shock, or fire.
After completing the service work, check for water leakage.
ITo avoid water damage to the furnishings, check for water
leak at the completion of all work.
Do not try to defeat the safety features of the unit.
Forced operation of the pressure switch or the temperature
switch by defeating the safety features for these devices, or
the use of accessories other than the ones that are recom-
mended by Mitsubishi Electric may result in smoke, fire, or
explosion.
Consult your dealer for proper disposal method.
CAUTION
Do not use the existing water piping.
Store the piping materials indoors, and keep both ends of
the pipes sealed until immediately before installation. Keep
the joints wrapped in plastic bags. If dust or dirt enters the
water circuit, it may damage the heat exchanger and cause
water leakage.
Only use water.
Only use clean water as a refrigerant. The use of water out-
side the specification may damage the refrigerant circuit.

[Maintenance access space] Secure enough access space to allow for the maintenance, inspection, and replacement of the motor, fan, drain pump, heat exchanger, and electric box in one of the following ways. Select an installation site for the indoor unit so that its maintenance access space will not be obstructed by beams or other objects.
(1) When a space of 300mm or more is available below the unit between the unit and the ceiling. (Fig.1) ·Create access door 1 and 2 (450×450mm each) as shown in Fig.2. (Access door 2 is not required if enough space is available below the unit for a maintenance worker to work in.)
(2) When a space of less than 300mm is available below the unit between the unit and the ceiling. (At least 20mm of space should be left below the unit as shown in Fig.3.) ·Create access door 1 diagonally below the electric box and access door 3 below the unit as shown in Fig.4. or ·Create access door 4 below the electric box and the unit as shown in Fig.5.
