Airflow doesn't disturb the cooled air in show-case
helps energy saving.
1 Uniformly distribute the air onto the louver.
2 3 Avoid airflow rising up.
2 3 Avoid dust attachment.
Allowing long piping and versatility.
The PLFY not only brings outside air into your space, but the PLFY-P-NBMU-E2
can also branch over to air-condition an adjacent room.

Note:
1. As for drain pipe, please use VP-25 O.D. 1-1/4(32) PVC TUBE.
Drain pump is included.
Max. lifting height is 33-7/16 (850mm) from the ceiling.
2. As for suspension bolt, please use M10 or W3/8. (Procured at local site)
3. Electrical box may be removed for the service purpose.
Make sure to slack the electrical wire little bit for control/power wires connection.
4. The height of the indoor unit is able to be adjusted with the grille attached.
5. For the installation of the optional high efficiency filter or optional multi-functional
casement.
1 Add 5-5/16"(135mm) to the dimensions marked on the figure.
2 The optional high efficiency filter becomes optional multi-functional casement
and concomitant use.
6. When installing the branch ducts, be sure to insulate adequately.
Otherwise condensation and dripping may occur.
(It becomes the cause of dew drops/water dew.)
As for necessary installation / service space, please refer to the left figure.
