ERSONNEL

As a professional installer, you have an obligation to know

the product better than the customer. This includes all safety

precautions and related items.

Prior to actual installation, thoroughly familiarize yourself

with this Instruction Manual. Pay special attention to all

safety warnings. Often during installation or repair, it is

possible to place yourself in a position which is more haz-

ardous than when the unit is in operation.

Remember, it is your responsibility to install the product

safely and to know it well enough to be able to instruct a

customer in its safe use.

Safety is a matter of common sense...a matter of thinking

before acting. Most dealers have a list of specific good safety

practices...follow them.

The precautions listed in this Installation Manual are intended

as supplemental to existing practices. However, if there is

a direct conflict between existing practices and the con-

tent of this manual, the precautions listed here take prece-

dence.

AFETY

RECAUTIONS

The following symbols and labels are used throughout this

manual to indicate immediate or potential safety hazards.

It is the owner’s and installer’s responsibility to read and

comply with all safety information and instructions accom-

panying these symbols. Failure to heed safety information

increases the risk of personal injury, property damage, and/

or product damage.

CARBON MONOXIDE POISONING HAZARD

Special Warning for Installation of Furnace or Air Handling Units in

Enclosed Areas such as Garages, Utility Rooms or Parking Areas

Carbon monoxide producing devices (such as an automobile, space

heater, gas water heater, etc.) should not be operated in enclosed areas

such as unventilated garages, utility rooms or parking areas because of

the danger of carbon monoxide (CO) poisoning resulting from the exhaust

emissions. If a furnace or air handler is installed in an enclosed area such

as a garage, utility room or parking area and a carbon monoxide producing

device is operated therein, there must be adequate, direct outside

ventilation.

This ventilation is necessary to avoid the danger of CO poisoning which

can occur if a carbon monoxide producing device continues to operate in

the enclosed area. Carbon monoxide emissions can be (re)circulated

throughout the structure if the furnace or air handler is operating in any

mode.

CO can cause serious illness including permanent brain damage or death.

This document provides installation instructions for the HKS Electric Heat Kit, emphasizing safety precautions and proper installation procedures for professional installers.

Function Description:

The HKS Electric Heat Kit is designed to be installed into specific models of air handlers (ARUFXX14YY, ARPTXX14YY, ASUFXX14YY, ASPTXX14YY, AVPTXX14YY, DVXXPTC14YY) to provide supplemental electric heating. The kit integrates with the air handler's electrical system to deliver heat as needed, controlled by a room thermostat. It includes heating elements, circuit breakers (for some models), and necessary wiring components to ensure safe and effective operation. The installation process involves mounting the heat kit within the air handler, connecting high and low voltage wiring, and performing a start-up sequence to verify functionality.

Important Technical Specifications:

Compatibility: Designed for specific ARUFXX14YY, ARPTXX14YY, ASUFXX14YY, ASPTXX14YY, AVPTXX14YY, and DVXXPTC14YY air handler models. The "XX" in the model numbers refers to the two-digit size, and "YY" refers to revision letters.
Electrical Requirements: The kit requires connection to a high voltage power supply. For two power supply electric heat kits, installers must check the air handler rating plate for Minimum Circuit Ampacity and Maximum Overcurrent Protection electrical ratings for each circuit.
Circuit Breakers: Some electric heat kits include circuit breakers. For 25kW applications, circuit breakers are supplied separately and must be attached to the heater plate. For downflow applications with circuit breakers, they must be rotated 180 degrees so the "ON" position is up.
Wiring: The kit includes lugs for high voltage power supply connections and a female multi-pin connector for low voltage connections. For three-phase applications, terminal block leads must be wired to the transformer as per the wiring diagram.
Ventilation (Carbon Monoxide Warning): While the electric heat kit itself does not produce carbon monoxide, the manual includes a critical warning regarding installation in enclosed areas (garages, utility rooms, parking areas) where other carbon monoxide producing devices (e.g., automobiles, space heaters, gas water heaters) might be present. Adequate, direct outside ventilation is required in such scenarios to prevent CO poisoning, as the air handler could recirculate CO emissions throughout the structure.
Installation Height (Garages): When installed in a garage, the heating element must be at least 18 inches above the floor to prevent personal injury or death.
Conductor Material: Only copper conductors should be used to avoid property damage or personal injury due to fire.

Usage Features:

Supplemental Heating: Provides electric heating to complement the air handler's primary function, ensuring comfort in various conditions.
Thermostat Control: Operation is governed by a room thermostat, allowing users to set desired temperatures and activate emergency heat functions.
Staged Heating: For kits with more than 10kW, the heating elements turn on in stages, with the first 10kW activating within 10-30 seconds of a call for heat, and additional stages activating subsequently.
Airflow Direction: The electric heat kit must be installed with the airflow decal pointing in the correct direction to ensure proper operation and heat distribution.

Maintenance Features:

Professional Installation: The manual explicitly states that only individuals meeting the requirements of an "Entry Level Technician" (as specified by AHRI) should install or repair the unit. This ensures proper installation and reduces the likelihood of product damage, personal injury, or death.
Pre-Installation Inspection: Installers are required to thoroughly inspect the kit upon arrival for any damage, loose screws, or wires, and to document any issues with the carrier.
Electrical Safety: Emphasizes disconnecting all power before servicing and being aware of multiple power sources to prevent electrical shock, property damage, personal injury, or death.
Wiring Diagram: For 25kW and three-phase heat kit applications, a wiring diagram is provided and must be installed in a prominently visible location on the exterior of the unit. Installers must also mark the diagram to indicate the number of heater element rows installed.
Start-Up Procedure: A detailed start-up sequence is provided to verify proper electrical connections, circuit breaker functionality, blower operation, and heating element activation, including specific timing for heat stages. An ammeter is required during start-up to monitor power supply.
Troubleshooting: If the blower or electric heat does not cycle appropriately during start-up, installers are instructed to disconnect all power supplies and troubleshoot according to service manual instructions.
Quality Assurance: The manufacturer highlights that their systems are designed and manufactured with high-quality standards, run-tested before leaving the factory, and use quality materials and components to reduce frequent causes of product failure, implying a focus on reliability and ease of service.
