Test Run; The Following Phenomena Do Not Represent Trouble (Emergency); Information On Rating Plate - Mitsubishi Electric CITY MULTI PUHY-P850YSGM-A Manual De Instalación

1. Use a separate power supply for the outdoor unit and indoor unit.
2. Bear in mind ambient conditions (ambient temperature,direct sunlight, rain water,etc.) when proceeding with the wiring and connections.
3. The wire size is the minimum value for metal conduit wiring. The power cord size should be 1 rank thicker consideration of voltage drops.
Make sure the power-supply voltage does not drop more than 10 %.
4. Specific wiring requirements should adhere to the wiring regulations of the region.
5. Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord (design 245 IEC57). For example,
use wiring such as YZW.
6. A switch with at least 3 mm contact separation in each pole shall be provided by the Air conditioner installation.
Warning:
• Be sure to use specified wires to connect so that no external force is imparted to terminal connections. If connections are not fixed firmly, it may cause
heating or fire.
• Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.
Caution:
• An earth leakage breaker must be attached to the power supply.
• Do not use anything other than breaker and fuse with correct capacity. Using fuse and wire or copper wire with too large capacity may cause a malfunction
of unit or fire.
Note:
• This device is intended for the connection to a power supply system with a maximum permissible system impedance shown in the above table at the
interface point (power service box) of the user's supply.
• The user has to ensure that this device is connected only to a power supply system which fulfils the requirement above.
If necessary, the user can ask the public power supply company for the system impedance at the interface point.

12. Test run

12.1. The following phenomena do not represent trouble (emergency)

Phenomenon
Indoor unit does not the perform cooling (heat-
ing) operation.
The auto vane runs freely.
Fan setting changes during heating.
Fan stops during heating operation.
Fan does not stop while operation has been
stopped.
No setting of fan while start SW has been
turned on.
Indoor unit remote controller shows "HO" in-
dicator for about five minutes when turning
ON universal power supply.
Drain pump does not stop while unit has been
stopped.
Drain pump continues to operate while unit
has been stopped.

When another indoor unit is performing the heating (cooling) operation, the cool-
ing (heating) operation is not performed.
Because of the control operation of auto vane, it may change over to horizontal
blow automatically from the downward blow in cooling in case the downward
blow operation has been continued for 1 hour. At defrosting in heating, hot adjust-
ing and thermostat OFF, it automatically changes over to horizontal blow.
Ultra-low speed operation is commenced at thermostat OFF.
Light air automatically changes over to set value by time or piping temperature at
thermostat ON.
The fan is to stop during defrosting.
Fan is to run for 1 minute after stopping to exhaust residual heat (only in heating).
Ultra low-speed operation for 5 minutes after SW ON or until piping temperature
becomes 35°C, low speed operation for 2 minutes thereafter, and then set notch
is commenced. (Hot adjust control)
System is being driven.
Operate remote controller again after "HO" disappear.
After a stop of cooling operation, unit continues to operate drain pump for three
minutes and then stops it.
Unit continues to operate drain pump if drainage is generated, even during a
stop.
