40MUAA: Installation Instructions

INTRODUCTION

The Air Handler models are R-410A Fan Coils designed for
installation flexibility allowing multi-position installation up-flow,
down-flow, horizontal right and horizontal left.
All fan coils have a DC fan motor with variable speeds for efficiency.
The units have been designed for up-flow, down-flow, and horizontal
orientations, including manufactured and mobile home applications.
These units require a field supplied air filter and electrical disconnect
and are designed specifically matching for R-410A refrigerant heat
pumps. These units are available for 18,000 through 60,000 BTUh
systems with nominal cooling capacity (depending on the local codes)
("Step 8 - Electrical Connections" on page 20)
