PERFORMANCE CHARTS
AIR HANDLER INSTALLATION
N.B. Cut off power supply at circuit breaker/fuse before proceeding with
the installation.
Please note that each air handler is factory inspected before shipping in
order to ensure that every component is operating efficiently.
The SCV series air handler is available in several models of various
capacities (from 400 to 2200 CFM). Since they are multi-position units, all
models adapt easily to many applications and are suitable for horizontal,
flow and downflow operations as shown in Fig. 5. In all cases, the air inlet
can be connected on the left, and right, bottom or back side of the unit. The
discharge is always onnected on the top side of the air handler. When
installed in vertical downflow position (top side facing down), use only a
‘‘L’’ or ‘‘T’’ shaped plenum, without openings or registers directly below the
unit.
LOCATION
You must install the air handler on a dry and solid base or in a suspended
ceiling. The area must be free of flammable liquids or vapors and combustible
materials. If you choose to suspend the unit, you must assemble the four (4)
‘’L’’ brackets (M-SCV39Z0) into the matching corner slots as shown in the
figure below. You must indicate to the air handler’s user the location of the
switches and disconnects. He must be able to quickly identify them in case of
an emergency. Moreover, the air handler should be located, as centrally as
possible, in the area to ventilate, in order to optimize air distribution in
all rooms.
CLEARANCE
The air handler is approved for ‘‘zero-inch’’ clearance. It means that you can
install it directly against a wall. Ducts for models of 1400 CFM and less can
also be installed with a zero-inch clearance (0 inches). However, ducts for
models of 2200 CFM and more must have a 1-inch clearance for the first 36
inches of the duct. Beyond 37 inches, this clearance can be reduced to 0
inches. If you have any questions concerning clearances, please refer to the
codes effective in your region Since it is necessary to open the door in the
front to perform the air handler maintenance inspection, you must leave at
least a 24-inch clearance in front of this door.
DUCTS
Ducts must be designed to deliver airflows to the specified external static
pressure. You should insulate the ducts crossing non-heated areas.
Moreover, use flexible return and supply connectors in order to avoid
vibrations as much as possible. To make your air handler even quieter, follow
these instructions:
- Cover the vertical return and supply ducts with soundproofing material
- Install at most one or two elbows between registers and the return and supply connectors
- Install flexible hangers to suspend the ducts
- Install baffles in elbows with a small radius of curvature
OPTIONAL ACCESSORIES
The air handler is equipped with all devices required for the addition of an
air-conditioner or heat pump (except the heat-cool thermostat). The
refrigerant and drainage pipes must be installed either in the air handler’s
supply or return duct and should not prevent you from removing the front door
of the air handler. You can also install a thermostat with an outdoor sensor
or a two-stage thermostat to control your air handler. For this type of
installation, refer to the instructions supplied with the thermostat as well
as the air handler’s wiring diagram.
N.B. Please note that if one of these accessories is installed, you must refer
to the appropriate guide.
CONTROL BOX INSTALLATION & ELECTRICAL CONNECTIONS
Note that this product must be connected by a qualified electrician
according to the electrical and building codes effective in your region.
This air handler must be connected to a 120 or 240/208-volt power source,
depending on the model. For 240V power supply, either copper or aluminum wires
can be used, except for 2200 CFM models where only copper wires can be used.
If you want to energize the air handler at 208 VAC, you must modify a
connection on the transformer’s terminal block: replace the wire connected to
L2/N with the wire not connected (isolated). Refer to the local and national
electrical codes to know which wire size, fuses and circuit breakers are
required. You can also connect a 24 VAC humidifier directly to the 24 VAC
power supply of the air handler, e.g. on the R and C terminals of the terminal
block.
NO CONTROL
When the air handler is used with no controller (model # SCV-P-xx0x), the
power cable must be wired through one of the two Ø7/8’’ KOE (electrical
knockouts), located on either side (right and left) of the air handler, and
connected to the appropriate wires in the junction box, as shown in Fig. 7. We
suggest the operator add an external switch or relay to control the air
handler unit:
LOW VOLTAGE CONTROL
When the air handler is used with low voltage control (model # SCV-P-xx4x),
the power cable must be wired through one of the two Ø 7/8’’ KOE (electrical
knockouts), located on either side (right and left) of the air handler, and
connected to the appropriate terminal blocks in the junction box, as shown in
Fig. 8. The low voltage control gives the installer the possibility to control
the air handler unit with a low voltage contact, e.g. a 24V thermostat. In
this case, the installer must use a different knock-out than the one used with
the power cable (high voltage) and must connect the external low voltage wires
to the appropriate terminal blocks in the junction box, as shown in Fig.
8.
WITH A LOCAL CONTROL BOX
When the air handler is used with a local controller (model # SCV-x-xx1x), the
installer can connect the unit by passing through a knock-out Ø7/8’’, located
on either side (left and right) of the air handler cabinet, and connect to the
terminal block as shown in Fig. 9. When the air handler is properly connected,
the installer can connect the controller to the thermostat by passing through
a different electrical knock-out Ø7/8’’ than the one used with the power cable
(high voltage). The detailed functions of the local control board connections
of the thermostat are explained in the following section.
CIR-019 CONTROL BOARD FUNCTIONS
The CIR-019 control board is used with all air handler models using a PSC
motor (model # SCV-P-xxxx). The following figure represents the control
board:
Input and output descriptions
The terminal block of the control unit fan housing (shown on the right side of
Fig. 9) has the following inputs and outputs:
- R: 24Vac output (18VA Max) can supply an external controller or thermostat
- C: Common internal transformer
- 3: High-speed control signal (24Vac)
- 2: Medium speed control signal (24Vac)
- 1: Low-speed control signal (24Vac)
Priority input controls
The highest selected speed is systematically prioritized. For example, if the
input of the low speed and medium are activated simultaneously, the medium
speed will be prioritized.
TYPICAL THERMOSTAT CONNECTION
The following figure shows a typical connection with a 24Vac thermostat. For
more clarity, the air handler cabinet is not shown on this fig. If needed,
refer to Fig. 9 to see the entire connection path.
TYPICAL HEAT PUMP CONNECTION

TYPICAL HEAT PUMP AND ECOBOOT™ CONNECTION
The following fig. 13 shows a typical connection with a 24Vac thermostat with
heat pump and Ecoboot™ heating system (SAB, SEB & SUB series). For more
clarity, the air handler cabinet is not shown in the figure. If needed, refer
to Fig. 9 to see the entire connection path.
CIR-028 CONTROL BOARD FUNCTIONS
The CIR-028 control board is used with all air handler models using an ECM
motor with a local control box. The following figure represents the control
board:
Input and output descriptions
The terminal block of the control unit fan housing (shown on the right side of
Fig. 14) has the following inputs and outputs:
- R: 24Vac output (18VA max) can supply an external controller or thermostat
- C: Common internal transformer
- 1: Airflow #1 control signal (24Vac)
- 2: Airflow #2 control signal (24Vac)
- 3: Airflow #3 control signal (24Vac)
Priority input controls
Input controls activate speed airflow prioritizing the highest selected. If
the airflow #1 input is adjusted to 500 CFM and airflow #2 is set to 700 CFM,
and both are activated simultaneously, airflow #2 set to 700CFM will be
prioritized.
Airflow adjustment
The control board has three (3) independently adjustable inputs (see Fig. 13).
To adjust the corresponding input to the desired airflow, turn the knob to the
desired airflow. Pilot lights indicate which, if any, input is activated. It
should be noted that only the highest active airflow will be prioritized.
TYPICAL THERMOSTAT CONNECTION
The following figure shows a typical connection with a 24Vac thermostat. For

CONTROL BOX REMOTE INSTALLATION
When the air handler is used with a remote control box (model # SCV-E-xx2&3x),
both assemblies are installed remotely from one another with a maximum
distance in between determined by the length of cable harness linking them
both (HAR-091 for 120’’ long and HAR-092 for 48’’ long). This alternate
configuration does not require any changes to the unit’s high voltage wiring
(refer to Fig. 9). The installer must remove the rectangle knock-out plate
located on either side (left and right) of the cabinet and install the plate
and connector assembly with two metal screws, as shown in Fig. 18
below.
The installer must determine the location of the remote control box and install it on the wall with four (4) screws, as shown in Fig. 19.
The installer must connect the air handler to the deported control box with the appropriate harness (part # HAR-091 for 120’’ length and HAR-092 for 48’’ length), as shown in Fig. 20.
CIR-020 CONTROL BOARD FEATURES
The CIR-020 is the electronic board used in the remote control box. The
following figure represents the control board with the location of its
different features:
FIG. 21
Input and output descriptions
The terminal block of the control unit fan housing (shown on the right side of
Fig. 21) has the following inputs and outputs:
- R (output): 24Vac (18VA max) can supply an external controller or thermostat
- C: common internal transformer
- 0-10V (input): signal proportional control 0-10V or 4-20 mA (with jumper)
- 0V (input): signal common 0-10V or 4-20 mA (with jumper)
- W1+ (input): signal control 24V (AC or DC)
- W- (input): signal common W1+
- W2+ (input): signal control 24V (AC or DC)
- W2- (input): signal common W2+
- G+ (input): signal control 24V (AC or DC)
- G- (input): signal common G+
- Y1+ (input): signal control 24V (AC or DC)
- Y1- (input): signal common Y1+
- Y2+ (input): signal control 24V (AC or DC)
- Y2- (input): signal common Y2+
- X1+ (input): signal control 24V (AC or DC)
- X1- (input): signal common X1+
- X2+ (input): signal control 24V (AC or DC)
- X2- (input): signal common X2+
Inputs (W1, W2, G, Y1, Y2, X1, and X2) are all inherently identical except for
their respective settings which are to be specified by the installer.
Therefore, their respective tags only serve to differentiate them in the
settings menu. There is no limitation for use or modification. However, the
name can’t be changed in the screen. For example, a control having an output
W3 could be connected to the input Y1. Therefore, the input programmed would
appear in Y1 menu.
Jumper descriptions
Jumpers are located just beside the terminal block on the control board (refer
to Fig.21) with the following descriptions:
- 24Vac jumper conversion 0-10V to 4-20mA (let jumper location J21 empty for 0-10V control or install jumper for 4-20mA control)
- Jumper junction between the input common 0-10V and the common of the air handler’s transformer
- Jumper junction between the input common W1 and the common of the air handler’s transformer
- Jumper junction between the input common W2 and the common of the air handler’s transformer
- Jumper junction between the input common G and the common of the air handler’s transformer
- Jumper junction between the input common Y1 and the common of the air handler’s transformer
- Jumper junction between the input common Y2 and the common of the air handler’s transformer
- Jumper junction between the input common X1 and the common of the air handler’s transformer
- Jumper junction between the input common X2 and the common of the air handler’s transformer
MENU button and adjusting knob
Fan control mode can be selected by pressing and holding the “MENU” button for
16 seconds, located just under the display screen (refer to Fig.
21). The control mode menu will be displayed (see figure below) to allow the
operator to choose the appropriate mode, CFM or H2O (“wc) or RPM by using the
rotating adjustment knob, located just under the “MENU” button (refer to Fig.
21). After selecting the mode, the operator must press the mode button to
validate the selection. When a mode is selected, each input is configured for
the selected mode. The active input with the highest value overrides all other
inputs.
To access the programming menu entries, the installer must press the “MENU”
button. By pressing this button, the installer can browse through all
programmable fan control inputs. To change a setting, the installer must turn
the adjustment knob to obtain the desired value. When the desired value is
obtained, the installer can press the “MENU” button to continue browsing. If
the same value is displayed for 8 seconds without being selected, the
interface will revert back to the main menu.
FIG. 24
The “0-10v” analog mode requires the selection of the upper limit CFM value
which will be associated to 10V. The “0-10v” input can also be converted to
accept a 4-20 mA signal.
FIG. 25
Pressure and temperature sensor
The use of a remote pressure sensor is required with the “H2O (“wc)” mode. A
temperature probe can also be used as an optional device. For this
application, the two probes need to be connected as shown in the figure below.
To be properly connected, the installer needs to secure the cable by using a
tie-wrap.
USB
For future applications.
Continuous ventilation switch
The fan control may be realized locally with the rocker switch on top of the
remote control (refer to Fig. 21). When this selector is in central position,
continuous ventilation is deactivated, whereas the “LO” and “HI” positions
activate the continuous ventilation. These two positions are programmable in
the input menu, as shown in Fig. 27:
FIG. 27
TYPICAL THERMOSTAT CONNECTION
The following figure shows a typical connection with a 24Vac thermostat using
the transformer of the air handler. In this example, the input “W1-” is not
connected since it is related to the controller with the jumper.
The following figure shows a connection with two (2) 24Vac thermostats, one using the transformer of the air handler and the other one using an external transformer. When wired to an external transformer, the thermostat “C” must to be connected in the input “Y1-”. If a “C” wire from an external system is connected to the control fan, the jumper needs to be removed (see Fig. 29).
TYPICAL HEAT PUMP CONNECTION
The following fig. 30 shows a typical connection with a 24 Vac thermostat with
a heat pump. For more clarity, the air handler cabinet is not shown on this
fig. If needed, refer to Fig. 20 to see the entire connection path.
FIG. 30
TYPICAL HEAT PUMP AND ECOBOOT™ CONNECTION
The following figure shows a typical connection with a 24Vac thermostat with a
heat pump and Ecoboot™ (SAB, SEB & SUB series) heating system.
FIG. 31
ELECTRICAL CONNECTION OF THE THERMOSTAT
The thermostat must be mounted on a connection box, at approximately 1.5 m (5
feet) above floor level, on a section of the wall exempt from pipes or air
ducts. Do not install the thermostat in a location with fluctuating
temperature measurements.
For example:
- close to a window, on an external wall, or close to a door leading outside
- exposed directly to the light or heat of the sun, a lamp, a fireplace or any other heat source
- close or in front of an air outlet
- close to concealed ducts or a chimney
- in a location with poor airflow (e.g. behind a door), or with frequent air draft conditions (e.g. head of stairs)
Seal wall openings in order to minimize the drafts which can alter temperature measurements. Read the thermostat user guide carefully.
MAINTENANCE
N.B. In order for the warranty to be valid, the unit must be cleaned
regularly.
Cut off power supply at circuit breaker/fuse before cleaning the unit. Use a
soft rag for dusting. When cleaning, use only a damp rag and non-abrasive dish
soap. Do not use abrasive or chemical cleaners because they may damage the
finishing. If the unit is used in a very dusty location, use a vacuum brush to
remove dust and other foreign objects.
Do not use cleaning products identified with these symbols:
N.B.
Note that there is an electrical current linked to the unit even if the
thermostat is set off. This means that there is a risk of electric shock as
long as the unit is energized.
PREVENTIVE MAINTENANCE
Do not try to repair your air handler yourself. Call a qualified technician.
However, before calling a technician, check the following points.
- Make sure fuses or circuit breakers are activated.
- Adjust the controls to create a demand for ventilation. If ventilation does not start, cut off the power supply and call a technician.
N.B. When calling a technician for maintenance or to order a replacement part, specify the model of your air handler as well as its serial number.
BLOWER
The blower motor is sealed and permanently lubricated, so it is not necessary
to lubricate it.
Even if you change the filter frequently, the blower’s blades and motors will
become dust laden after a few months. The entire blower assembly should be
inspected annually. If needed, vacuum out the dust. If you cannot clean the
blower without removing it from the air handler, this service must be
performed by a qualified technician.

CONDITIONS, EXCLUSIONS AND DISCLAIMER OF LIABILITY
This warranty is exclusive and in lieu of all other representations and
warranties (except of title), expressed or implied, and Stelpro expressly
disclaims and excludes any implied warranty of merchantability or implied
warranty of fitness for a particular purpose. Stelpro’s liability with respect
to products is limited as provided above.
Stelpro shall not be subject to any other obligations or liabilities
whatsoever, whether based on contract, tort or other theories of law, with
respect to goods or services furnished by it, or any undertakings, acts or
omissions relating thereto. Without limiting the generality of the foregoing,
Stelpro expressly disclaims any liability for property or personal injury
damages, penalties, special or punitive damages, damages for lost profits,
loss of use of equipment, cost of capital, cost of substitute products,
facilities or services, shutdowns, slowdowns, or for other types of economic
loss or for claims of a dealer’s customers or any third party for such
damages. Stelpro specifically disclaims all consequential, incidental and
contingent damages whatsoever.
This warranty does not cover any damages or failures resulting from: 1) a
faulty installation or improper storage; 2) an abusive or abnormal use, lack
of maintenance, improper maintenance (other than that prescribed by Stelpro)
or a use other than that for which the unit was designed; 3) a natural
disaster or an event out of Stelpro’s control, including, but not limited to,
hurricanes, tornadoes, earthquakes, terrorist attacks, wars, overvoltage,
flooding, water damages, etc. This warranty does not cover any accidental or
intentional losses or damages, nor does it cover damages caused by negligence
of the user or owner of the product. Moreover, it does not cover the cost of

The warranty is limited to the repair or the replacement of the unit or the
refund of its purchase price, at the discretion of Stelpro. Any parts replaced
or repaired within the warranty period with the written authorization of
Stelpro will be warranted for the remainder of the original warranty period.
This warranty will be considered null and void and Stelpro will have the right
to refuse any claims if products have been altered without the written
authorization of Stelpro and if the nameplate numbers have been removed or
modified. This warranty does not cover scratches, dents, corrosion or
discoloration caused by excessive heat, chemical cleaning products and
abrasive agents. It does not cover any damage that occurred during the
shipping. Some states and provinces do not allow the exclusion or limitation
of incidental or consequential damages and some of them do not allow
limitations on how long an implied warranty lasts, so these exclusions or
limitations may not apply to you. This warranty gives you specific legal
rights and you may have other rights which vary from state to state or from
province to province.
