Mitsubishi Electric CITY MULTI PVFY-P12NAMU-E Technical & Service Manual page 3

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 refrigerant 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.
When installing the unit in a small space, take appropriate
precautions to prevent leaked refrigerant from reaching the
limiting concentration.
Leaked refrigerant gas will displace oxygen and may cause
oxygen starvation. Consult your dealer before installing the
unit.
HWE1405A
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 a refrigerant
leak.
If leaked refrigerant is exposed to a heat source, such as a
fan heater, stove, or electric grill, toxic gases will be gener-
ated.
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.
