5.3. Drain check (Fig. 5-7)
Pour water in the drain pan and check that it comes out the drain pipe end, after
confirmation, reinstall the panel.
6.1. Precautions
Warning:
Electrical work should be done by qualified electrical engineers in accordance
with "Engineering Standards For Electrical Installation" and supplied installa-
tion 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.
I
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 controller, trans-
mission cables) is brought in direct contact with the power cable outside the unit.
4. Ensure that there is no slack on all wire connections.
5. Some cables (power, remote controller, transmission cables) above the ceiling
may be bitten by mice. Use as many metal pipes as possible to insert the cables
into them for protection.
6. Never connect the power cable to leads for the transmission cables. Otherwise
the cables would be broken.
7. Be sure to connect control cables to the indoor unit, remote controller, and the
outdoor unit.
8. Put the unit to the ground on the indoor unit side.
9. Select control cables from the conditions given in "Types of control cable".
Caution:
Be sure to put the unit to the ground on the indoor unit side also. Do not con-
nect the earth cable to any gas pipe, water pipe, lightening rod, or telephone
earth cable. Incomplete grounding may cause a risk of electric shock.
Working process
I PKFY-P06/P08NAMU-E (Fig. 6-1)
1. Remove the front panel, then remove the corner box from the lower right corner of
the indoor unit.
2. Install each wire into the unit.
3. Remove the tapping screw (1), and then remove the electric parts cover.
4. Connect each wire properly to the terminal block.
• In consideration of future servicing, please leave some leeway for the wiring length.
• Route the wires as shown in the illustration.
(Do not route the wires in front of the address board cover.)
• If using the MA remote controller, connect it to the connector for the accessory
remote controller cable ¢.
5. Put all the parts back the way they were.

(PG connection or the like.)
A means for the disconnection of the supply with an isolation switch, or similar de-
vice, in all active conductors shall be incorporated in the fixed wiring.

1. Remove the corner box.
2. Install each wire into the unit.
3. Open the front grill, remove the tapping screw (1), and then remove the terminal
block cover.
