7.4. Drain piping work

• Ensure that the drain piping is downward (pitch of more than 1/100) to the outdoor
(discharge) side. Do not provide any trap or irregularity on the way.
• Ensure that any cross-wise drain piping is less than 20 m (excluding the difference
of elevation). If the drain piping is long, provide metal braces to prevent it from
waving. Never provide any air vent pipe. Otherwise drain may be ejected.
• Use a hard vinyl chloride pipe VP-25 (with an external diameter of 32 mm) for
drain piping.
• Ensure that collected pipes are 10 cm lower than the unit body's drain port.
• Do not provide any odor trap at the drain discharge port.
• Put the end of the drain piping in a position where no odor is generated.
• Do not put the end of the drain piping in any drain where ionic gases are generated.

8. Duct work

• When connecting ducts, insert a canvas duct between the main body and the
duct.
• Use non-combustible duct components.
• Install sufficient thermal insulation to prevent condensation forming on air inlet
and air outlet duct flanges, and air outlet ducts.

9. Electrical wiring

Precautions on electrical wiring
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 ca-
pacity or has an installation failure, it may cause a risk of electric shock or fire.
1. Be sure to install an earth leakage breaker to the power.
2. 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.
3. Ensure that there is no slack on all wire connections.
4. Some cables (power, remote controller, transmission cables) above the ceiling
may be bitten by mouses. Use as many metal pipes as possible to insert the
cables into them for protection.
5. Never connect the power cable to leads for the transmission cables. Otherwise
the cables would be broken.
6. Be sure to connect control cables to the indoor unit, remote controller, and the out-
door unit.
7. Put the unit to the ground on the outdoor unit side.
Caution:
• Be sure to put the unit to the ground on the outdoor unit side. 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.
• If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
Types of control cables
1. Wiring transmission cables
Note:
• Transmission cables shall not be lighter than polychloroprene sheathed
flexible cord. (Design 245 IEC 57)
• Cable diameter
2
More than 1.5 mm
• Cable length
Less than 80 m.
• Circuit rating
S1 - S2: 230V AC
S2 - S3: 24V DC
* The figures are not always against the ground.
S3 terminal has 24V DC against S2 terminal. However between S3 and S1, these
terminals are not electrically insulated by the transformer or other device.
2. Remote controller cables
Types of cables Sheathed 2-core cable (unshielded) CVV
Cable diameter 0.3 to 1.25 mm
Length Less than 500 m

1. Insert the drain hose (accessory) into the drain port.
(The drain hose must not be bent more than 45° to prevent the hose from break-
ing or clogging.)
The connecting part between the indoor unit and the drain hose may be discon-
nected at the maintenance. Fix the part with the accessory band, not be adhered.
2. Attach the drain pipe (O.D. ø32 PVC TUBE, field supply).
(Attach the pipe with glue for the hard vinyl chloride pipe, and fix it with the band
(small, accessory).)
3. Perform insulation work on the drain pipe (O.D. ø32 PVC TUBE) and on the
socket (including elbow).

Always install horizontal.

9.1. Power supply wiring

• Power supply cords of appliances shall not be lighter than design 245 IEC 57 or
227 IEC 57.
• A switch with at least 3 mm contact separation in each pole shall be provided by
the Air conditioner installation.
Power cable size: more than 1.6 mm

C Indoor unit
[Selecting non-fuse breaker (NF) or earth leakage breaker (NV)]
To select NF or NV instead of a combination of Class B fuse with switch, use the fol-
lowing:
• In the case of Class B fuse rated 15 A or 20 A,
NF model name (MITSUBISHI): NF30-CS (15 A) (20 A)
NV model name (MITSUBISHI): NV30-CA (15 A) (20 A)
Use an earth leakage breaker with a sensitivity of less than 30 mA 0.1 s.
Caution:
Do not use anything other than the correct capacity breaker and fuse. Using fuse,
wire or copper wire with too large capacity may cause a risk of malfunction or fire.
9.2. Connecting remote controller, indoor
and outdoor transmission cables
Warning:
• The compressor will not operate unless the indoor/outdoor transmission
phase connection is correct.
• The connection wiring between the outdoor and indoor units can be
extended up to a maximum of 50 meters, and the total extension including
the crossover wiring between rooms is a maximum of 80 m.
• Connect indoor unit TB4 and terminal block for indoor-outdoor transmission line.

Cable 3-core 1.5 mm , in conformity with design 245 IEC 57.
• Install a remote controller following the manual supplied with the remote controller.
• Connect the "1" and "2" on indoor unit TB15 to a MA remote controller. (Non-polar-
ized 2-wire)
• Connect the remote controller's transmission cable within 10 m using a 0.75 mm
core cable. If the distance is more than 10 m, use a 1.25 mm
