Introduction - Carrier Performance 40MBDQ Series Installation Instructions Manual

INTRODUCTION

The Ducted Slim models are R-410A fan coils designed with
application flexibility in mind. The 9K-48K sizes can be
mounted horizontally or vertically (upflow) while the 58K size
can be mounted only horizontally.
A rear and bottom return is available for field modification on
the 9K-48K sizes to match the different applications.
All these fan coils have a DC fan motor with variable speeds
for efficiency and comfort. The static pressure can be manually
set up or use the constant air volume control.
The ducted fan coil unit is shipped with a condensate lift pump
providing a maximum lift of 29.5in (750mm).

NOTES:
- If the outdoor unit is higher than the indoor unit, prevent rain
from flowing into the indoor unit along the connection pipe by
creating a downward arc in the connection pipe before it
enters the wall and enters the indoor unit. Doing so helps
ensure rain drips from the connection pipe before it enters the
wall.
- Piping and the interconnecting wiring are field supplied.
- Fig. 3 is a sketch. Different models may differ slightly.
