PEFY-P·VMA-E2 model
J Up to 700 mm
N Drain socket (accessory)
O Horizontal or slightly upgradient
[PEFY-P·VMA model]
1. Insert the drain socket (accessory) into the drain port (insertion margin: 32mm).
(Attach the hose with glue, and fix it with the band (small, accessory).)
2. Attach the drain pipe (O.D. ø32 PVC TUBE PV-25, field supply).
(Attach the pipe with glue, and fix it with the band (small, accessory).)
3. Perform insulation work on the drain pipe (O.D. ø32 PVC TUBE PV-25) and on
the socket (including elbow).
4. Check the drainage. (Refer to [Fig. 7.3.1])
5. Attach the insulating material, and fix it with the band (large, accessory) to insu-
late the drain port.

1. Insert the drain socket (accessory) into the drain port.
The connecting part between the indoor unit and the drain socket may be dis-
conncted 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).

8. Duct work
•
In connecting duct, insert canvas duct between unit and duct.
•
Use incombustible material for duct parts.
•
Provide full insulation to inlet duct flange and outlet duct to prevent condensa-
tion.
•
Be sure to change the position of air filter to the position where it can be serviced.

Procedure for changing the rear inlet to the bottom inlet.
Caution:
When the duct is connected to the inlet at the bottom of the unit, the sound
pressure level will be greater by approximately 10 dB than when the duct is
connected to the inlet at the back of the unit.
For this reason, it is recommended to connect the duct to the back inlet.
When using the inlet at the bottom of the unit, offset the position of the inlet on
the indoor unit relative to the inlet on the ceiling as shown in Figures <A> and
<B> to minimize noise.
[Fig. 8.0.2] (P.5)
A Filter
1. Remove air filter. (First remove filter lock screw.)
2. Remove the bottom plate.
3. Fit the bottom plate to the rear of the body. [Fig. 8.0.3] (P.5)
(Position of lug-holes on the plate are different from those for rear inlet.)
When the plate is attached on
the rear side, it exceeds the
height of the rear body panel.
Replicate the plate along
the slit when there is not
enough room above for the
entire unit.

7.3. Confirming drain discharge
Make sure that the drain-up mechanism operates normally for discharge
and that there is no water leakage from the connections.
•
Be sure to confirm the above in a period of heating operation.
•
Be sure to confirm the above before ceiling work is done in the case of a new con-
struction.
1. Remove the water supply port cover on the same side as the indoor unit piping.
2. Fill water into the feed water pump using a feed water tank. In filling, be sure to
put the end of the pump or tank in a drain pan. (If the insertion is incomplete,
water may flow over the machine.)
3. Perform the test run in cooling mode, or connect the connector to the ON side of
SWE on the Indoor controller board. (The drain pump and the fan are forced to
operate without any remote controller operation.) Make sure using a transparent
hose that drain is discharged.

4. After confirmation, cancel the test run mode, and turn off the main power. If the
connector is connected to the ON side of SWE, disconnect it and connect it to the
OFF side, and attach the water supply port cover into its original position.

Caution:
•
Inlet duct of 850 mm or more should be constructed.
To connect the air conditioner main body and the duct for potential equal-
ization.
•
To reduce the risk of injury from metal sheet edges, wear protective gloves.
•
To connect the air conditioner main body and the duct for potential equal-
ization.
•
The noise from the intake will increase dramatically if intake is fitted
directly beneath the main body. Intake should therefore be installed as far
away from the main body as possible.
Particular care is required when using it with bottom inlet specifications.
•
Install sufficient thermal insulation to prevent condensation forming on
outlet duct flanges and outlet ducts.
•
Keep the distance between the inlet grille and the fan over 850 mm. If it is
less than 850 mm, install a safety guard not to touch the fan.
•
To avoid electrical noise interference, do not run transmission lines at the
bottom of the unit.
