Mitsubishi CITY MULTI PURY-EM-YNW-A1(-BS) Series Installation Manual page 5

Do not touch the refrigerant pipes and refrigerant line components with bare hands during
and immediately after operation.
- The refrigerant in the pipes will be very hot or very cold, resulting in frostbite or burns.
Do not touch the electrical parts with bare hands during and immediately after operation.
- Doing so may result in burns.
Ventilate the room while servicing the unit.
- If the refrigerant leaks, oxygen deficiency may result. If the leaked refrigerant comes in contact
with a heat source, toxic gas will be generated.
If you notice any abnormality (e.g., a burning smell), stop the operation, turn off the power
switch, and consult your dealer.
- Continuing the operation may result in electric shock, malfunction, or fire.
Properly install all required covers and panels on the terminal box and the control box.
- If dust or water enters the unit, this may result in electric shock or fire.
Periodically check the unit base for damage.
- If the damage is left uncorrected, the unit will fall and cause serious injury.
Consult your dealer for the proper disposal of the unit.
- The refrigerant oil and the refrigerant in the unit will pose a risk of environmental pollution, fire,
or explosion.
Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer.
The unit shall be stored in a room without continuously operating ignition sources (for
example: open flames, an operating gas appliance or an operating electric heater.)
Do not pierce or burn.
Be aware that refrigerants may not contain an odour.
The unit shall be stored in a space where any possible leakage of refrigerant will not
accumulate.
When installing an HBC controller, take safety measures in accordance with the European
Standard, based on the system refrigerant amount and the room volume as shown in the
figure below. (The installation restrictions can be simply found by using the flowchart
provided on a separate sheet.)
