these instructions thoroughly and follow all warnings or cautions attached to the unit. Consult local building codes and National Electrical Code

(NEC) for special requirements.

INTRODUCTION

Models FA4B, FB4B, FC4C, and FH4B are designed for flexibility and can be used for upflow, horizontal, or downflow (kit required and

manufactured and mobile home) applications. These units are designed to meet the low air leak requirements currently in effect. Because of this,

the units need special attention in the condensate pan and drain connection area and when brazing tubing. These units are available for systems

of 18,000 through 60,000 Btuh nominal cooling capacity. Factory authorized electric heater packages are available in sizes 3 through 30kw. See

Product Data Literature for available accessory kits.

HEATER PACKAGES

This unit may or may not be equipped with an electric heater package. For units not equipped with factory installed heat, a factory approved, field

installed UL listed heater package is available from your equipment supplier. See unit rating plate for a list of factory approved heaters. Heaters

that are not factory approved could cause damage which would not be covered under the equipment warranty. If fan coil contains a factory installed

heater package, minimum circuit ampacity (MCA) and maximum fuse/breaker may be different than units with a same size field installed accessory

heater. The difference is not an error and is due to calculation difference per UL guidelines.

INSTALLATION

PROCEDURE 1—CHECK EQUIPMENT

Unpack unit and move to final location. Remove carton taking care not to damage unit.

Inspect equipment for damage prior to installation. File claim with shipping company if shipment is damaged or incomplete. Locate unit rating

plate which contains proper installation information. Check rating plate to be sure unit matches job specifications.

PROCEDURE 2—MOUNT UNIT

Unit can stand or lie on floor, or hang from ceiling or wall. Allow space for wiring, piping, and servicing unit.

IMPORTANT: When unit is installed over a finished ceiling and/or living area, building codes may require a field-supplied secondary condensate

pan to be installed under the entire unit. Some localities may allow as an alternative, the running of a separate, secondary condensate line. Consult

local codes for additional restrictions or precautions.

A. Upflow Installation

If return air is to be ducted through a floor, set unit on floor over opening and use 1/8- to 1/4-in. thick fireproof resilient gasket between duct,

unit, and floor.

Side return is a field option on slope coil models. Cut opening per dimensions. (See Fig. 1.) A field-supplied bottom closure is required.
