BEFORE YOU CALL A SERVICEMAN

1.Make sure thermostat temperature selector is set above room temperature for heating or below room temperature for cooling. If thermostat is equipped with heating/cool- ing sub-base, make sure system switch (see Figure 1) is set to “HEAT” for furnace operation or set to “COOL” for optional air- conditioning operation.

2.Check main household service panel to see if appropriate circuit disconnect(s) for appliance power supply is on.

3.Refer to instructions under Before Operating System for pre-operation checks.

4.Refer to instructions under Before Each Heating Season for maintenance proce- dures and recommended service checks.

5.Refer to owner’s manual provided with optional air conditioner or heat pump (if installed) for service and maintenance.

NOTE: All servicing of this heating appliance other than the normal maintenance described in this section must be done by authorized trained service personnel. Do not open the control panels (see Figure 1) at any time.

Please specify the complete model and serial numbers shown on the furnace data label (see Figure 1) for all warranty service and when or- dering replacement parts or optional equipment. Refer to the replacement parts list provided with the furnace for part numbers.

OPTIONAL AIR CONDITIONER AND HEAT PUMP

Your E3 Series electric furnace is approved for use with an optional central air conditioner or a heat pump. To adapt this heating appliance to a “total comfort system,” contact your nearest NORDYNE distributor.

Optional air conditioners and heat pumps are listed by Underwriters’ Laboratories (UL) or Environmental Testing Laboratories (ETL) and certiﬁ ed by ARI and the Canadian Standards Association (CSA), orWarnock Hersey or ETLC. These cooling systems include energy-sav- ing components to provide maximum cooling performance at electrical energy usage levels established by federal standards. Refer to the operation instruction label on your furnace for the optional air conditioning equipment approved for your heating appliance.

SECTION 2. INSTALLER INFORMATION GENERAL

These instructions and speciﬁ cations are pri- marily intended to assist qualiﬁ ed individuals experienced in the proper installation of home heating and air conditioning appliances. Some local codes require licensed personnel for the installation and service of this type of equip- ment. Approved installation, operation, and maintenance of this central heating system appliance must be in accordance with the listed speciﬁ cations contained in these instructions and other documents supplied with the furnace and/or optional air conditioning equipment. Refer to local authorities having jurisdiction for further information.

Before beginning installation, read these instruc- tions thoroughly. Follow all warnings and cautions in the instructions and on the unit.

Improper installation, service adjustment, or maintenance can cause explosion, ﬁ re, electri- cal shock or other conditions which may result in personal injury or property damage. Unless otherwise noted in these instructions, use only factory-authorized kits and accessories when modifying this product.

Overview of E3 Furnace

E3E(-) Series electric furnaces are available in two models.E3EH models are equipped with the standard two-speed blower. E3EH models can be easily converted for use with NORDYNE split- system air conditioners and heat pumps. E3EB models are air-conditioning ready; that is, they are equipped with a multi-speed (four-speed) blower, blower relay, and cabinet insulation kit. SeeTable 3 for cooling and heat pump availability with factory installed blower.

For typical unducted return air downﬂow applica- tions, an air-conditioner or heat-pump coil can be installed by mounting the coil directly on top of the furnace without adding sheet metal cavities or cutting and trimming wood panels.

A return air grille for closet or alcove installations is available. For downﬂ ow alcove installations, the grille (with frame provided) may be attached to the top of the furnace and all paneling and trim ﬂ ushed to it. This installation provides an access door for future installation of NORDYNE air conditioning or heat pump coils on top of the furnace.

E3 specifications

The Nordyne E3 is an innovative and efficient heating and cooling system designed to meet the demands of modern residential and commercial spaces. With a focus on energy efficiency and advanced technology, the E3 series offers a variety of features tailored to provide optimal comfort throughout the year.

One of the standout characteristics of the Nordyne E3 is its multi-stage heating and cooling capability. This system utilizes a two-stage compressor, which allows it to operate at different capacities based on the current temperature demand. By adjusting its output, the E3 can maintain a more consistent indoor climate while maximizing energy savings. This not only enhances comfort but also reduces energy bills over time.

The E3 series also includes a variable-speed blower motor, which significantly improves airflow management. This technology enables the system to operate quietly and efficiently, reducing energy consumption while providing precise temperature control. Homeowners can enjoy a comfortable environment without the disruptive noise often associated with traditional HVAC systems.

Another key feature of the Nordyne E3 is its advanced refrigerant technology. The system uses R-410A refrigerant, an environmentally friendly option that has a lower impact on ozone depletion compared to older refrigerants. This commitment to sustainability aligns with the growing demand for eco-friendly solutions in the HVAC industry.

Additionally, the Nordyne E3 incorporates integrated Wi-Fi connectivity, allowing users to control their system remotely via smartphone or tablet. This smart technology enables homeowners to adjust temperature settings, monitor energy usage, and schedule maintenance alerts from virtually anywhere.

Energy Star certification further highlights the E3’s commitment to energy efficiency. Systems bearing this label are rigorously tested to ensure they meet strict guidelines for energy consumption, providing peace of mind for consumers looking to reduce their carbon footprint.

In summary, the Nordyne E3 heating and cooling system stands out for its energy-efficient design, advanced technologies, and commitment to comfort. With features like multi-stage operation, variable-speed motors, eco-friendly refrigerants, and smart home compatibility, it represents a significant step forward in HVAC technology. Homeowners can rely on the E3 to create a comfortable living environment while also contributing to a more sustainable future.
