WARNING

INTRODUCTION

Model FE4A, FE5A fan coils are designed to be installed with a
communicating User Interface. The FE4A, FE5A fan coils will

provide airflow at a rate commanded by the User Interface. The
nominal airflow/ton rate is 350 CFM/ton. The User Interface will

modify the commanded airflow under certain operating modes.

Refer to the User Interface literature for further system control
details. This fan coil will not respond to commands from a

common thermostat except under certain emergency situations
explained in this document. The instructions contained herein

provide guidance to successfully install this fan coil.
Model FE5A fan coil units are designed for upflow or downflow

applications only. Model FE4A fan coil units are designed for

flexibility and can be used for upflow, horizontal, or downflow
applications. These units are designed specifically for Puron

r

(R- 410A) refrigerant and must be used only with Puron

r

refrigerant air conditioners and heat pumps as shipped.
These units are designed to meet cabinet air leakage of less than

2% at 0.5 inches W.C. and cabinet air leakage less than 1.4% at 0.5
inches W.C. when tested in accordance with ASHRAE 193

standard. Because of this, units need special attention in the
condensate pan and drain connection area and when brazing

tubing.
These units are available for application in systems of 18,000
through

60,000

Btuh

nominal

cooling

capacities.

Factory- authorized, field- installed electric heater packages are
available in 5 through 30 kW. See Product Data for available

accessory kits.
