SECTION 2: SAFETY

MORTEX PRODUCTS INC. 501 TERMINAL RD FORT WORTH, TX 76106 Page 3
How The Air Handler Works – Heating Cycle
How the Furnace Works
This furnace must only be installed in the downow orientation.
The furnace is equipped with the controls necessary for proper
and safe operation. Figure 1 shows the furnace in the downow
position and the location of the circuit breakers and low
voltage fuse. The furnace is equipped with a blower assembly
and transformer for no-heat models or a blower assembly,
transformer, electric heat contactors, circuit breakers, and electric
heating elements for electric heat models.
The transformer provides 24 VAC for the operation of the furnace
controls and thermostat. When the thermostat calls for heat,
24 VAC is sent through the furnace low voltage terminal block
(LVTB) and the over-temperature limits to the contactor coil which
causes the contactor contacts to close. This sends 208/240 VAC to
the electric heating elements which causing them to heat up. The
furnace blower motor is then energized on the heating speed.
The blower draws cool air from the living space, passes it across
the heating elements, and circulates the warm air through the
ductwork to the living space. When the thermostat is satised, the
electric heating elements are de-energized and the blower motor
is de-energized. The furnace is now in“standby” awaiting the next
call for heat.
Visual Inspection of Furnace
The homeowner/user should visually inspect the furnace every
month for any defects or problems. The items to be inspected are:
1. The physical support of the furnace with no sagging cracks,
gaps, etc.
2. The furnace casing for any obvious signs of deterioration from
rust or corrosion.
3. The supply duct connection is sealed to the furnace casing. The
return connection (furnace base) is sealed to the oor base.
4. The furnace must be serviced by a qualied service technician
annually, preferably at the start of each heating season.
FIRE OR ELECTRICAL HAZARD
Servicing heating/cooling equipment can be hazardous
due to electrical components.
Only trained and qualified personnel can service or repair
heating/cooling equipment. The homeowner must never
try to perform service, repair or maintenance on this air
handler.
Untrained service personnel can perform only basic
maintenance functions such as cleaning of exterior
surfaces and replacing the air filters ONLY!
Observe all precautions in the manuals and on the
attached labels when working on this air handler.
SECTION 3: HOMEOWNER/USER INFORMATION
Figure 1: Circuit Breaker Locations
The Service Technician
If the furnace gives any indication of improper operation, a
service technician should be called to inspect and repair the
furnace. The service technician is allowed to perform the normal
routine care of the furnace and can detect potential problems
and then make corrections before trouble develops. Preventative
maintenance of this type will allow the furnace to operate with
minimal concerns to the homeowner/user and will provide years
of comfort.
Warranty and Responsibilities
It is the sole responsibility of the homeowner to make certain
the furnace has been properly installed and adjusted to operate
properly.
The manufacturer warrants the furnace to be free from defects
in material or workmanship for a stated time in the warranty
agreement. The manufacturer will not be responsible for any
repair costs to correct problems due to improper setup, improper
installation, improper furnace adjustments, adding parts that
are not listed for use with this furnace, improper operating
procedures by the homeowner/user or repairs performed by the
homeowner/ user.
Examples of service calls not covered by warranty:
1. Correcting faulty duct system in the home. This can be due
to an insufficient number of ducts or ducts that are too small to
provide proper air-flow through the air handler.
2. Correcting electrical wiring problems in the supply wiring to
the air handler.
3. Resetting circuit breakers or ON/OFF switches used for
servicing.
4. Problems caused by installation and operation of any outdoor
unit or air quality devises which are not approved for use with
this air handler.
5. Improper thermostat settings or calibrating the thermostat.
6. Problems caused by construction debris that has fallen into
the furnace.
7. Replacement of fuses.
8. Insufficient air-flow problems caused by dirty air filters.
9. Furnace malfunction or component premature failure caused
by restrictions in the return or supply ducts causing low air-flow.

MORTEX PRODUCTS INC. 501 TERMINAL RD FORT WORTH, TX 76106 Page 4
The homeowner should establish a clear understanding of these
responsibilities with the installer and /or service company so
there will be no misunderstanding of what will be covered under
warranty later.
While Homeowner or User is Away
The furnace is equipped with safety shutoff devices which are
designed to prevent it from overheating in case of a malfunction.
For this reason, it is never practical to assume the furnace will
operate unattended for long periods of time. Examples of a
malfunction that can cause significant damage to the home
would be:
1. The furnace blower motor fails and the heating elements
on the safety shutoff devices while the temperature inside
the home continues to drop. Water pipes will freeze and could
burst once their temperature falls below 32°F (0°C) resulting in
significant damage to the structure.
2. The furnace blower motor or outdoor unit fails in the summer
resulting in the temperature inside the home to rise above the
setpoint. If the temperature of the home rises above the rated
temperature of appliances, appliance failure can occur.
3. If the homeowner to be away from home for a long period of
time, they should have someone check on the home every day,
especially when the outside temperatures will be below 35°F
(1.7°C) or above 75°F (23.9°C) to ensure the furnace is operating
properly. This will help prevent water pipes from freezing or
appliances from failing.
If the Furnace Fails to Operate Properly
If any abnormalities are observed while the furnace is operating,
perform the following checks:
1. Check the setting on the thermostat to make sure the
thermostat is set above the room temperature.
2. Check to see if the electrical power is turned on at the circuit
breakers at the main electrical panel (circuit breaker box) or
check any switches that may be used for service disconnect
switches. These are often mistaken for light switches and are
turned off.
3. Make sure the air filters are clean, return grilles clean, are not
obstructed, and supply air registers are open.
4. If the cause of the malfunction is not obvious, the homeowner/
user must not attempt to service the furnace. A qualified
service company must be called to repair the furnace.
Should overheating occur turn the circuit breakers on
the control box and the main electrical service entrance
(Circuit Breaker Box) to the off position. Call qualified
service personnel to troubleshoot and repair the furnace.
DO NOT allow the furnace to continue to cycle on the
limit controls.

SECTION 3: FURNACE CONTROLS SECTION 4: SEQUENCE OF OPERATION
This section explains how the furnace control operate. Refer to
Figure 8 for component locations.
1. Limit Control(s) – Each electric heating element has a limit
switch directly in front of it to sense the heating element
temperature to prevent overheating. The limit switch opens
if the temperature rises above the set point and interrupts the
24 VAC signal to the heater contactor coil which disconnects
electrical power to the heating element.
2. Heater Contactor(s) –The contactors are controlled by
the thermostat. Upon a call for heat, 24 VAC is sent from the
thermostat “W” terminal to the contactor coil(s) causing the
contactor contacts to close which sends 208/240 VAC to the
electric heating elements. When the call for heat has been
satisfied, the contactor contacts open removing the 208/240
VAC from the heating elements.
3. Circuit Breaker(s) – The circuit breakers are designed as short
circuit protection for the electric heating elements and can also
be used to disconnect the electrical power to the furnace.
NOTE: The circuit breaker(s) are not intended to protect the
wiring from the main control panel (home circuit breaker box)
to the furnace, so the appropriate size breaker(s) or fuse(s) must
be selected (See furnace rating plate) and installed in the main
electrical panel to protect the electrical supply wiring and
furnace.
4. Transformer – The transformer is used to reduce the 208/240
VAC line voltage to 24 VAC which is used by the system control
circuit.
5. 3 Amp Low Voltage Fuse – This fuse is used for over-current
protection of the 24 VAC circuit and transformer.
Figure 8: Component Locations
Continuous Blower
When the thermostat fan switch is in the “ON”position
(continuous indoor fan operation), the circuit between the“R” and
“G”terminals in the thermostat is completed causing 24 VAC to be
sent through the GREEN wire to the “G” terminal on the furnace
low voltage terminal block (LVTB). This energizes the furnace
blower motor and air will be circulated through the ductwork
into the conditioned space. The indoor fan motor will operate
continuously until the thermostat fan switch is switched to the
“AUTO” position.
Intermittent Blower
When the thermostat fan switch is set in the “AUTO” position
(intermittent indoor fan operation), the indoor blower motor
is only energized when there is a call for cooling or heating
operation. Different motor speed taps are typically use for cooling
and heating operating. The indoor fan motor will operate until the
call for cooling or heating is satisfied.
Heating Cycle
When the thermostat is set in the “HEAT” mode and the fan switch
on the thermostat is set in the “AUTO” position, a call for heat
completes the circuit between the“R” and “W” terminals in the
thermostat and 24 VAC is sent from the“W” thermostat terminal
through the WHITE thermostat wire to the W” terminal on the low
voltage terminal block (LVTB).
24 VAC is sent from the LVTB “W” terminal through the limit
controls to the heater contactor coils which closes the contactor
contacts and energizes the heating elements with line voltage.
The blower motor heating speed lead is connected to the “W”
terminal on the LVTB so the blower is energized on the selected
heating speed tap.
The blower will continue to operate until the call for heat has
been satisfied. The electric heater contactor coil is de-energized
which opens the contactor contacts and de-energizes the heating
elements. The 24 VAC signal is also removed from the blower
motor heating speed tap which de-energizes the blower motor.
The furnace is now in standby mode awaiting the next heating
cycle.
The 12 kW, 15 kW and 20 kW models have a BLACK wire that can
be disconnected from the spade terminal on the back of the LVTB
“W” terminal and connected to the wire from the thermostat
“W2” terminal (2nd stage heat) for two-stage heating operation.
A thermostat that has the second stage (W2) heating feature
must be used. The 2nd stage heat cycle is enabled when the room
temperature falls approximately 3 below the thermostat set
point. Once the room temperature is within approximately 1 of
the thermostat set point, the 2nd stage of heat is de-energized
until the thermostat calls for the 2nd stage heat again.
For personal safety be sure to turn the electrical power
For personal safety, turn the electrical power“OFF” to the
furnace at the main electrical panel (circuit breaker box)
before performing service or maintenance on the furnace.
Homeowners/users should never attempt to perform any
servicing or maintenance which requires opening the furnace
control box covers.

SECTION 5: TROUBLESHOOTING
The following checks should be made before troubleshooting
the furnace controls for a no-heat issue.
1. Check all of the circuit breakers in the main electrical panel and
on the furnace control box cover to make sure they are in the
“ON”position and have not tripped.
2. Check the 3-amp low voltage fuse on the left side of the control
box. If the fuse is blown, check the wiring with an ohmmeter for
a short to ground. If shorted, repair the short and replace the fuse.
3. Check any electrical switches that are external to the furnace to
make sure they are turned on.
4. Check all wiring connections make sure they are securely fastened.
If the furnace still will not operate, check the following.
1. Check to see if the voltage is above 200 volts for a 208 VAC
power supply and above 220 volts for a 240 VAC power supply.
If there is no voltage or the voltage is low, check the circuit
breakers in the main electrical panel or the electrical supply
wiring to the furnace.
2. If the blower is operating, but there is no heat, check the heater
contactors to be sure they are closing or check the limit controls
to make sure they are not open.
3. If the motor is not running, check for 208 - 240 VAC on the L1
and L2 contactor terminals. Check for 24 VAC at the motor
speed tap terminals connected between the low voltage
terminal block (LVTB) “G”and “C” terminals for continuous fan
operation, between the LVTB “W” and “C” terminals for heating
operation, or between the LVTB “Y” and “C” terminals for cooling
operation.
4. If 240 VAC is present on the L1 and L2 contactor terminals
and 24 VAC is present on the motor speed tap terminals and the
motor is still not operating, replace the motor.
5. Refer to Figure 9 and Table 1 for the motor terminal connections.
To avoid personal injury or property damage, make certain
that the motor leads cannot contact non-insulated metal
components of the unit.
Table 1: Constant Torque Motor Terminal Connections
Heating Element Not Heating
Check for 208 - 240 VAC between terminals T1 and T2 of the
heater contactor(s). If 208 - 240 VAC is present, check the
resistance across the heating element terminals. If the heating
element resistance is infinity (open circuit) for any heating
element, replace the defective heating element.
The heater design is as follows:
• The 5kW and 6kW models have one 5 kW or 6kW heating
element.
• The 8kW and 10 kW models have a heater assembly with two
4kW or 5 kW heating elements.
• The 12kW model has a heater assembly with two 6kW heating
elements.
• The 15 kW model has one heater assembly with two 5 kW
heating elements and one heater assembly with one 5 kW
heating element.
• The 20 kW model has two heater assemblies, each with two 5 kW
heating elements.
Cooling Cycle
When the thermostat is set in the “COOL” mode and the fan
switch on the thermostat is set in the “AUTO” position, a call for
heat completes the circuit between the“R” and“Y” terminals in
the thermostat and 24 VAC is sent from the“Y” thermostat
terminal through the YELLOW thermostat wire to the“Y” terminal
on the low voltage terminal block (LVTB). The blower motor
cooling speed lead is connected to the “Y” terminal on the LVTB
so the blower is energized on the selected cooling speed tap.
The blower will continue to operate until the call for cooling has
been satisfied. The 24 VAC signal is removed from the blower motor
cooling speed tap which de-energizes the blower motor. The
furnace is now in standby mode awaiting the next cooling cycle. Figure 9: Constant Torque Motor Terminals

make any noises or vibrate during operation.
21. When the blower check is complete, set the thermostat to the
desired mode and temperature.
To avoid personal injury, take precautions to not touch
non-insulated electrical components.
Avoid wearing loose clothing or any items that can become
caught in moving parts, such as the blower wheel. This can
cause serious personal injury.
The correct heating element amp draw is approximately as
follows:
4 kW Heating Element = 16.7 amps
5 kW Heating Element = 20.8 amps
6 kW Heating Element = 25.0 amps
If the heating element current draw is below the amps shown
above or at 0.0, replace the heating element.
If 208 - 240 VAC is not present between the T1 and T2 terminals
(load) of a heater contactor, but there is 208-240 VAC present
between terminals L1 and L2 (line) of that heater contactor,
check for an open limit control and replace the open limit
control if it has failed open.
If 208-240 VAC is not present between the T1 and T2 terminals
(load) of a heater contactor, but 208-240 VAC is present between
the terminals L1 and L2 (line) of the heater contactor(s) and
there is 24 VAC across the coil of that contactor, replace the
heater contactor.
