INTRODUCTION

This instruction covers the installation of downflow base kits on models EBP, EBX, EBV and EBW fan coils. (See Table 1.) The
device is designed to provide a means of eliminating open passage through building structure (per UL and NFPA 90B), and
provides a 1-in. clearance between plenum and initial penetration of structure.
DESCRIPTION AND USAGE

The downfiow base kit is required in downflow installations of fan coils. The kit maintains 1-in. minimum clearance between
unit discharge plenum, ductwork, and combustible materials and also provides a gap-free seal with the floor. Before installing

the downflow base, convert the fan-coil unit for downflow installation by positioning unit with filter section at top and rotating
coil 180 degrees. See downflow bracket kit Installation Instructions for details.

INSTALLATION

1. Cut a hole in floor large enough for clearance of downflow base brackets. See Fig. 1 and Table 1to determine clearance

dimensions.

2. Set downflow base on floor with brackets inserted into hole.

3. Fasten base firmly to floor with screws through base flanges.

4. Set unit on downflow base inserting unit discharge duct flange through hole in base.

5. Connect ductwork to unit discharge duct flange.
