INTRODUCTION

AWARNING

To avoid the possibility of

electrical shock do not

open electrical box pan-

els.

TO OPERATE FURNACE

1. Be sure electrical power to fur-

nace is turned on at the house-

hold service box.

2. Set wall thermostat to the

desired temperature.

3. If furnace is equipped with Air

Conditioning, the System

Switch, located at the wall ther-

mostat, must be turned to

HEAT in order for the furnace

to operate in the heating mode.

WARNING

If you have an air condi-

tioner which does not

use the furnace blower

for air distribution and

operates completely

independent of the fur-

nace, the thermostat

system must have an

interlock to prevent the

furnace and air condi-

tioner from operating at

the same time. Such

operation could cause

equipment damage,

energy waste and over-

heating of the home.

The interlock system usually con-

tains a heat-cool switch which

must be turned to either HEAT or

COOL to activate either heating or

cooling operation.

If an interlock system has not been

provided, the electrical supply to

the furnace must be turned OFF at

the household service box, when

the air conditioner is being used.

When operating the furnace, the

electrical supply to the air condi-

tioner must be turned OFE

TO SHUT FURNACE OFF

1. Turn thermostat to its lowest

setting.

NOTE: Furnace will still operate if

room temperature falls below ther-

mostat setting.

2. For complete shut-down turn

off electrical power at the

household service box.

SEQUENCE OF

OPERATION

When room thermostat calls for

heat, 24-volt power is supplied to

the heating element switches. As

soon as the first heating element

switch closes, the blower starts

and power is supplied to the first

heating element. Each additional

element is staged on in succes-

sive intervals.

When the room thermostat is satis-

fied and no more heat is required,

the elements sequence off in the

reverse order and the blower will

then turn off.

LIMIT CONTROLS

Each element has an automatic

limit switch which is wired into the

circuit and shuts off power to that

element if the heat at that point

exceeds the allowable maximum

heat.

BLOWER REMOVAL

NOTE: Only authorized service

technicians should remove the

blower.

To remove blower from furnace,

turn off power at household service

box, turn furnace circuit breakers

OFF. Disconnect wiring to blower,

and remove five (5) screws holding

blower in furnace and slide blower

out from front of the furnace. See

Figure 1.

Re-install blower in reverse order

when assembling back into fur-

Race.

FURNACE OPERATION

CIRCUIT BREAKERS

Your electric furnace is equipped

with a unique safety feature -cir-

cuit breakers. These circuit break-

ers are located behind the door of

the furnace, near the bottom of the

furnace. See Fig. 1. tf a compo-

nent should fail inside the furnace,

the circuit breakers will prevent

damage that can be caused by an

electrical short. If the breakers

ever trip, they can be reset by first

turning off the power to the furnace

at the home's circuit breaker panel.

See Warning below. Then remove

the furnace door and reset the cir-

cuit breaker in the furnace. Re-

install the furnace door and turn

the power back on at the home's

breaker panel. If for some reason

these circuit breakers should trip

again, a service technician should

be contacted as a problem exists

inside the furnace. A list of autho-

rized service centers is provided

with every furnace and will assist

you in obtaining service for your

furnace.

AWARNINGI

You must first de-ener-

gize the furnace at the

main household power

supply and lock it.

LUBRICATION

The blower motor bearings are fac-

tory sealed. Additional lubrication

is not required.

BLOWER ASSEMBLY

Every electric furnace comes

equipped with a blower capable of

operating a heat pump or air condi-

tioner. With the addition of the

proper heat pump, you can enjoy

comfort and savings all year long.

An air conditioner will also work

with your furnace and will provide

cool summer days, at a very low

operating cost.

AIR FILTER

The filter supplied with the furnace

is of the throw-away type. Filters

need to be cleaned frequently.

Shake out all loose dirt, and use

vacuum cleaner to clean addition-

ally. This method of cleaning will

prolong life of filters. DO change

filters often since clean filters not

only provide added comfort, better

and cleaner environment, but

increase the efficiency of the fur-

nace as well.

FILTER LOCATION: The furnace's

front panel must be removed to

gain access to the filter of the

downflow furnace. (See Figure 1.)

However, the filter for the upflow

furnace* is located behind the

return air grill, adjacent to the fur-

nace closet or any other location in

the return air.

RETURN AIR

Return air must be provided back

to the circulating blower in order to

provide air distribution. DO NOT

OBSTRUCT ANY RETURN AIR

GRILLE. To do so will cause the

furnace heating elements to cycle

off and on repeatedly.

IMPORTANT:

WHILE YOU'RE AWAY

The power supply to your furnace

is equipped with either a fused or

breaker type disconnect. In case of

an overload, this will interrupt the

operation of your furnace until it is

reset or fuse replaced. For this

reason it is never practical to

assume that the furnace will oper-

ate unattended for long periods of

time, especially if there is a possi-

bility of damage to your property

because of freezing. So, if you

plan to be away, arrange for some-

one to check your home every day

or so.

AT THE BEGINNING OF

EACH HEATING SEASON

NOTE: Be sure electrical supply to

furnace is turned off at the house-

hold service box and furnace circuit

breakers before cleaning.

1. Replace filters as discussed

previously. Clean dust and lint

from in and around the fur-

nace. Clean dust and lint from

blower and blower compart-

ment.

2. If furnace fails to operate prop-

erly:

a.Be sure electrical power is

being supplied to furnace.

Check main household

power supply.

b.lf, after following this proce-

dure, the furnace still fails to

operate, shut off furnace and

contact your service techni-

cian.

YOUR AUTHORIZED

SERVICE TECHNICIAN

Your furnace's best friend is your

service technician. If the unit gives

any indication of improper opera-

tion, call your authorized service

technician, tf the service technician

is allowed to perform the normal

routine care of your furnace, he

many times can detect potential

difficulties and make corrections

before trouble develops. Preven-

tive maintenance of this type will

allow you to operate this unit with a

minimum of concern and, at the

same time, pay for itself in added

years of comfort.

OPTIONAL

AIR CONDITIONING

ACCESSORIES

This furnace is already equipped

with a blower and control system

to add-on air conditioning up to 4

tons and heat pump up to 3-1/2

tons. Insulation and coil shelf kit

(3500-8941 for downflow or 3500-

8961/A for upflow) must be

installed when adding on such

remote air conditioning systems.

[AWARNINGI

Failure to install this

insulation and coil shelf

kit could result in dam-

age to equipment and/or

personal injury. Liability

and warranty from the

manufacturer could also

be void.

NOTE: If the controls are located

at the top of the unit, the furnace is

an upflow furnace and the airflow is

forced up through the furnace and

into the airways.

HIGH PERFORMANCE

BLOWER ACCESSORY

PACKAGE

All EB furnaces are already

equipped with a blower and con-

trol system to add-on air condition-

ing up to 4-tons and heat pump up

to 3 1/2-tons. If the requirement is

to achieve more than specified

than the production blower inside

the furnace would have to be

replaced with an accessory blower

package 3500-7901". This acces-

sory blower package would deliver

air conditioning up to 5-tons, and

heat pump up to 4-tons. Acces-

sory package (3500-7901")

includes blower, insulation, coil

shelf, trap, clamps, etc. Please

refer to the installation instructions

packed with the accessory pack-

age for more information.

CAUTION

All areas around the fine

sets, drain hoses and

other openings in the fur-

nace should be sealed

airtight. Use some mold-

able compound or caulk-

ing to seal the area.

Failure to do so may

result in loss of perfor-

mance and premature

compressor failure.
