Safety Precautions
Read before installation and performing electrical work
Thoroughly read the following safety precautions prior to installation.
Observe these safety precautions for your safety. This equipment may have
adverse effects on the equipment on the same power supply system. Contact the
local power authority before connecting to the system.
Symbol explanations
WARNING
This symbol indicates that failure to follow the instructions exactly as
stated poses the risk of serious injury or death.
CAUTION
This symbol indicates that failure to follow the instructions exactly as
stated poses the risk of serious injury or damage to the unit.
Indicates an action that must be avoided.
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.)
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.
Doing so may cause the unit or pipes to burst, or result in explosion or fire
during use, during repair, or at the time of disposal of the unit. It may also
be in violation of applicable laws. Mitsubishi Electric Trane HVAC US LLC
cannot be held responsible for malfunctions or accidents resulting from the
use of the wrong type of refrigerant.
Ask your dealer or a qualified technician to install the unit.
Improper installation by the user may result in water leakage, electric shock,
or fire.
Properly install the unit on a surface that can withstand its weight.
Unit installed on an unstable surface may fall and cause injury.
Only use specified cables. Securely connect each cable so that the terminals
do not carry the weight of the cable.
Improperly connected cables may produce heat and start a fire.
Take appropriate safety measures against wind gusts and earthquakes to prevent
the unit from toppling over. Improper installation may cause the unit to
topple over and cause injury or damage to the unit.
Only use accessories (i.e., air cleaners, humidifiers, electric heaters)
recommended by Mitsubishi Electric Trane HVAC US LLC.
Do not make any modifications or alterations to the unit. Consult your dealer
for repair. Improper repair may result in water leakage, electric shock, or
fire.
Do not touch the heat exchanger fins with bare hands. The fins are sharp and
pose a risk of cuts.
Properly install the unit according to the instructions in the Installation
Manual. Improper installation may result in water leakage, electric shock, or
fire.

GB
Have all electrical work performed by an authorized electrician 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.
Disconnect all electric power supplies before accessing of electric parts
(inner of control box, fan motor, drain pump etc.)
Touching electric parts result in electric shock.
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 infiltrate and pose
a risk of electric shock, smoke, or fire.
Consult your dealer or a qualified technician when moving or reinstalling the
unit. Improper installation may result in water leakage, electric shock, or
fire.
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
recommended by Mitsubishi Electric Trane HVAC US LLC may result in smoke,
fire, or explosion.
After completing the service work, check for a water leak.
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
outside the specification may damage the refrigerant circuit.
Install the unit so that external force is not applied to the water pipes.

- Indoor unit has been Thermo ON in Cool/Dry mode for at least 16 min. 2)
When the water inlet temp (TH22) or water outlet temp (TH23) is 33.8°F or
less, continuously for 3 min.
Released condition: Anti-freezing control is cancelled when ANY one of the following conditions is satisfied, and an additional 3 minutes have passed. 1) Water inlet temp (TH22) and water outlet temp (TH23) are 50°F or above continuously for 1 min. 2) The condition of the Thermo OFF has become complete by thermal-regulating (unit satisfies by set point). 3) The operation mode becomes a mode other than COOL or Dry. 4) The operation is stopped (unit is turned off). 5) Three min have passed from start of anti-freezing control. Thermo OFF = The IC coil is not actively cooling or heating. Thermo ON = The IC coil is actively cooling or heating.

depends on the settings of the remote controller. The heater turns on
regardless of the fan speed. *5 The fan stops and the heater turns off,
depending on the type of error.
- If a heater is installed in the duct, do not use CN22. By doing so, the fan will turn off when the heater is on, which may result in fire.
(2) Back-up heating will not be performed when the heater turns on while demand control is performed (not a request item). (3) This is applicable only to the R410 series. Make the settings for the following dip switches on the outdoor unit control board
before switching on the power.

5. External static pressure Five levels of external static pressure are
available for selection. Set the setting either by using the switches on the
control board (SW21-1, SW21-2, and SW21-5) or from the function selection
screen on the remote controller.
Note: When the static pressure setting was set from the remote controller, the
actual setting and the switch setting on the control board may not match
because the latest setting from the remote controller overrides the previous
setting. To check the latest static pressure setting, check it on the remote
controller, not on the switch. If the static pressure setting for the duct is
lower than that for the unit, the fan of the unit may repeat start/stop, and
the outdoor unit may remain in a stopped state. Match the static pressure
settings for the unit to that for the duct.
