Press and hold down the A [FILTER] and B [TEST] buttons at the same time for two seconds or longer.
After a while, the function selection display disappears and the remote controller returns to the air conditioner off display.
* Do not operate the air conditioner from the remote controller for 30 seconds after the end of function selection.
Note:
When the functions of an indoor unit were changed by function selection after the end of installation, always indicate the set contents by entering a
mark in the appropriate check field of Table 1 and Table 2.

Precautions on electrical wiring
Warning:
• Electrical work should be done by qualified electrical engineers in ac-
cordance with "Engineering Standards For Electrical Installation" and sup-
plied installation manuals. Special circuits should also be used. If the
power circuit lacks capacity or has an installation failure, it may cause a
risk of electric shock or fire.
• Always use the designated cable for wiring, and connect it correctly. Se-
cure it so that the cable applies no external pressure to the terminal con-
nection. If the connection is faulty or the cable is not fully secured, over-
heating or fire could result.
• Be sure to use specified cables and connect them firmly so that no exter-
nal wiring force is exerted on terminal connections. Loose connections
may cause heat or fire.
1. Be sure to take power from the special branch circuit.
2. Be sure to install an earth leakage breaker to the power.
3. Install the unit to prevent that any of the control circuit cables (remote control-
ler) is brought in direct contact with the power cable outside the unit.
4. Ensure that there is no slack on all wire connections.
5. Remote controller cable above the ceiling may be bitten by mice. Use as many
metal pipes as possible to insert the cable into them for protection. Where the
remote controller cable is exposed, protect the cable by running it through a
metal pipe.
6. Never connect the power cable to leads for the remote controller cables. Other-
wise the cables would be broken.
7. Fix power source wiring to control box by using buffer bushing for tensible force
(PG connection or the like).
8. Set up the unit so that the wiring for the remote controller and the M-NET
(MELANS) wiring do not produce electrical interference with the power supply
cable. (Do not route them together in the same conduit.)
9. Be sure to provide designated grounding work to the unit.
10. Give some allowance to wiring for electrical part box of the unit, because the
box is sometimes removed at the time of service work.

Caution:
• Be sure to put the unit to the ground on the outdoor unit side. Do not
connect the earth cable to any gas pipe, water pipe, lightening rod, or
telephone earth cable. Incomplete grounding may cause a risk of electric
shock.
• Some installation sites may required installation of an earth leakage
breaker. Failure to install it may result in an electric shock.
• Always use an earth leakage breaker and fuse with the specified capac-
ity. Use of a fuse with a capacity larger than that specified, or use of a
piece of wire or copper wire may cause breakdown or fire.
• Depending on the location of the unit, a current leakage breaker may be
required. If a current leakage breaker is not installed, electric shock could
result.
• Do not use breakers or fuses with a capacity different from the correct
one. If large-capacity fuses, wire, or copper wiring are used, accident or
fire may result.
The following table is an example. The selection of other capacities should be
determined in accordance with the relevant standards.

a maximum permissible system impedance ZMAX of 0.07
Ω
0.05 : PRH-P250 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 fulfills the requirement above.
If necessary, the user can the ask the public power supply company for
the system impedance at the interface point.
