SAFETY CONSIDERATIONS

Installing and servicing of heating and air conditioning equipment can be hazardous due to system pressures and electrical components. Only

trained personnel should install or service heating and air conditioning equipment.

Untrained personnel can perform basic maintenance functions such as cleaning coils, or cleaning and replacing filters. All other operations should

be performed by trained personnel. When working on heating and air conditioning equipment, observe precautions in literature, on tags, and on

labels attached to the unit.

Follow all safety codes. Wear safety glasses and work gloves. Have a fire extinguisher available.

Recognize safety information. This is the safety-alert symbol

When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, and CAUTION. These words are used with the safety-alert symbol. DANGER identifies the

most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or

death. CAUTION is used to identify unsafe practices, which would result in minor personal injury or product and property damage. NOTE is used

to highlight suggestions which will result in enhanced installation, reliability, or operation.

INTRODUCTION

This instruction covers installation of Smart Heat electric heater packages Part No. KFCEH0101H10, KFCEH0201H15, and KFCEH0301H20 into

FA4, FB4, FC4, and FX4 fan coils. Check unit rating plates for compatibility of fan coil and electric heater combinations. See Table 1 for heater

package usage.

NOTE: The Smart Heat option is for use only on heat pumps, and is not approved for any other application.

DESCRIPTION AND USAGE

The Smart Heat electric heater package options allow the addition of accessory heaters and related controls to models FA4, FB4, FC4, and FX4

fan coils with heat pump outdoor units only. See Table 1 for heater package usage.

The Smart Heat electric heater package options enhance performance of heat pump by managing the electric heat. Heating elements are staged

on individually as required to maintain dwelling set point temperature. The controller will adjust the indoor blower speed tap to reduce airflow

in the ultra comfort mode.

The controller is not a substitute for good installation and ductwork practices. All ductwork should be free of air leakage and insulated.

Performance may not be satisfactory if good practices are not followed.

NOTE: Electric heaters require a minimum airflow. See Table 2 for minimum motor speed selection before installing. There is a 1-in. minimum

clearance to combustible materials for the first 36 in. of ductwork on all fan coils with 20-kw packages, and 024, 033, and 038 size fan coils with

15-kw heater packages.

WARNING: Before beginning any installation or modification, be sure the main electrical disconnect switch(es) is in

the OFF position. Tag the disconnect with a suitable warning label. Electrical shock can cause personal injury or death.

INSTALLATION

PROCEDURE 1—INSTALL ELECTRIC HEATER ASSEMBLY

NOTE: Ensure heater coils are not deformed or damaged during heater installation.

1. Make sure power is off.

2. Remove blower access panel of fan coil unit.
