INSTALLATION

IMPORTANT: Follow all applicable local and national
electrical codes when installing this accessory.

Follow all local and NEC (National Electrical Code)
codes. If a single power source is to be used, size the wire to
include power exhaust MCA and MOCP. (See Table 5.)

NOTE: For R-410A units, refer to unit nameplate for MCA and
MOCP for installed power exhaust. For R-22 units, use the cal­culations detailed below.

Check MCA and MOCP when power exhaust is powered
through the unit (must be in accordance with NEC and/or lo­cal codes). Determine the new MCA including the power ex­haust using the following formula:

MCA New = MCA unit only + MCA of Power Exhaust

For example, using a R-22 gas heat, electric cooling, 6-ton
unit with MCA = 28.9 and MOCP = 35, with
CRPWREXH030A01 power exhaust:

MCA New = 28.9 amps + 1.5 amps = 30.4 amps

If the new MCA does not exceed the published MOCP, the
MOCP would not change. The MOCP in this example is 35
amps, the MCA New is below 35, therefore the MOCP is ac­ceptable. If “MCA New” is larger than the published MOCP,
raise the MOCP to the next larger size. For separate power,
the MOCP for the power exhaust will be 15 amps per NEC.

NOTE: For 575-v installations, a field-supplied and installed
transformer (part no. HT01AH859) must be used with 208/230v
power exhaust.

The vertical power exhaust can be used with 3 different
types of economizers. While the physical installation of the
power exhaust assembly stays the same, the wiring differs
among the three economizers types. These instructions de­scribe the installation and wiring for each type. The 3 types
are:

• EconoMi$er IV with controller W7212

• EconoMi$er2 without controller. It is generally used with
a separate PremierLink controller or a field-supplied
building management system.

• EconoMi$er X with controller W7220.

WARNING

Electrical shock can cause personal injury and death.
Before beginning any modification, be certain that the

main-line electrical disconnect switch is in the OFF posi­tion. Close the main gas supply shutoff valve. Tag discon­nect switch and gas valve with suitable warning labels.

NOTE: Before installing, ensure voltage of power exhaust
agrees with power supply to equipment.

1. Turn off unit power supply and install lockout tag. For
gas units, turn off the gas supply

2. Remove the power exhaust knockout plugs located on
the lower left side of the EconoMi$er accessory. (See
Fig. 2.)

Fig. 2 — Power Exhaust Knockout Location

3. Remove the RTU unit filter panel to allow access to the
inside of the rooftop.

4. The panel covering the horizontal return opening on the
unit may also be removed for easier access and installa­tion. Be sure to replace this panel when installation is
complete.

5. Install the vertical economizer per the instructions pro­vided with the economizer. Do not install the rainhood
shipped with the economizer. Set aside the aluminum air
filter for use with the power exhaust.

6. Remove fan shield so power exhaust can lay flat without
bending the shield or damaging the roof.

7. Remove the shipping blocks from the bottom of the
accessory vertical power exhaust. (See Fig. 3.)

Fig. 3 — Shipping Block Removal

8. There may be a hinged door panel in place of the filter
panel. Open the hinged door, remove the screws and
hinges, remove the door and set it aside. Keep all screws

and hinges.

9. Place the power exhaust close to the EconoMi$er to
allow for wiring harness connection.

CAUTION

Failure to follow this caution may result in equipment dam­age.

Be careful to route wires to avoid pinching or cutting
during assembly. It can be difficult to protect the wires
while attaching the power exhaust to the unit.

10. Follow the wiring instructions specific to the
EconoMi$er. Be sure power exhaust wiring does not
interfere with damper operation.

Power Exhaust Wiring with EconoMi$er IV and
EconoMi$er X

Follow these instructions if using the vertical power ex-

haust with EconoMi$er IV or EconoMi$er X accessories.

1. The 2-wire low voltage harness from the power exhaust
and the 24 to 36 in. (610 or 915 mm) low voltage exten­sion harness are plugged together for shipping. Unplug
these 2 harnesses for installation.

2. Insert the 2-wire low voltage harness plug from the
power exhaust into the top knockout on the EconoMi$er.
(See Fig. 2.)

3. From the rear of the EconoMi$er, connect the 24-in.
(601mm) low voltage extension harness plug to the
power exhaust harness.

4. For EconoMi$er IV: Route the other end of the low volt-
age extension harness to the EconoMi$er IV controller.
(See Fig. 4.) The harness is connected to the controller
by connecting the tan wire to the tan wire 24 VAC COM
terminal on the controller. The terminal on the gray wire
is connected to terminal EF1 on the controller. See Fig. 6
and 7 for EconoMi$er wiring diagrams. Install the gray
jumper wire on the controller from the exhaust fan termi­nal (EF), to the 24 VAC HOT terminals. The gray jumper
is shipped wire tied to the control harness.
For EconoMi$er X: Route the other end of the low volt­age extension harness to the EconoMi$er X 12 pin plug,
(PL6). (See Fig. 5.) The gray wire from the low voltage
extension harness connects to the yellow wire coming
from terminal 8 in the 12 pin plug. The tan wire from the
low voltage extension harness connect to the brown wire
coming from terminal 4 in the 12 pin plug. See Fig. 6 and
7 for EconoMi$er X wiring diagrams.

5. The high voltage harness from the power exhaust and the
high voltage extension harness are plugged together for
shipping. Unplug these 2 harnesses for installation.

6. Insert the high voltage harness plug from the power
exhaust into the bottom knockout on the EconoMi$er.
(See Fig. 2 and 4.)
R-410A Rooftop Models Only: For single point wiring
application, connect the power exhaust power wire har­ness to the compressor contactor or indoor fan contactor

If a single power source is to be used, size wire to include
power exhaust MCA and MOCP.

For R-410A units, refer to the unit nameplate for MCA and
MOCP for installed power exhaust.

For R-22 units use the following calculations
Check MCA and MOCP when power exhaust is powered

through the unit. Determine the new MCA including the power
exhaust using the following formula:

MCA New = MCA unit only + MCA of Power Exhaust
For example, using an electric cooling, 6-ton R-22 unit with

MCA = 28.9 and MOCP = 35, with CRPWREXJ030A01 power exhaust.
MCA New = 28.9 amps + 1.5 amps = 30.4 amps
If the new MCA does not go over the MOCP published, then MOCP would

not change. The MOCP in this example is 35 amps, the MCA New is below
35, therefore the MOCP is OK. If “MCA NEW” is larger than the published
MOCP, raise the MOCP to the next larger size. For separate power, the
MOCP for the power exhaust will be 15 amps per NEC.

NOTES:

1. The power exhaust comes with a short (24 in. or 36 in.) low voltage extension harness. EconoMi$er 2 includes a longer low voltage har­ness which is to be used to route back through the unit to the RTU controller in the RTU control box. Use separate knockout for high and
low voltage wires.

2. Low voltage wires with EconoMi$er X attach to wire leads on the EconoMi$er X plug.

3. Ensure main power line, disconnect, and fuse/breaker are sized per National Electric Code.

Power Exhaust Wiring with EconoMi$er and
PremierLink Controller or RTU-MP/OPEN

Use these instructions when installing the vertical power
exhaust with EconoMi$er2 and PremierLink or RTU-MP/
OPEN controller.

1. A low voltage extension harness is supplied with the

EconoMi$er2 (without controller) beginning with unit
serial number 2703Gxxxxx. Prior to serial 2703Gxxxxx,
the supplied low voltage extension harness is not long
enough to reach the PremierLink control board and will
have to be field extended.
The two-wire low voltage harness and the low voltage
extension harness are wire tied together for shipping.
Separate the harnesses for installation and discard the
short low voltage extension harness supplied with power
exhaust.

2. Insert the 2-wire low voltage harness plug from the

power exhaust into the top knockout on the
EconoMi$er2 accessory. (See Fig. 2 and 9.)

3. From the rear of the EconoMi$er2 accessory, connect the

low voltage extension harness plug to the two-wire har­ness from the power exhaust. (See Fig. 9.)

4. Route the other end of the low voltage extension harness

to the PremierLink controller. (See Fig. 9.)

5. The high voltage harness from the power exhaust and the

high voltage extension harness are plugged together for
shipping. Unplug these 2 harnesses for installation.

6. Insert the high voltage harness plug from the power

exhaust into the bottom knockout on the EconoMi$er2
accessory. (See Fig. 2 and 9.)

7. From the rear of the EconoMi$er2 accessory, connect the

long high voltage extension harness plug to the power
exhaust harness. (See Fig. 9.)

8. Route the other end of the long high voltage extension
harness through the HVAC unit to the control box. (See
Fig. 8.) The harness must be routed through the grom­mets provided in the unit. Do not drill routing holes. Be
careful not to route the power exhaust harness on top of
the indoor coil.

9. Wire the end of the high voltage harness extension to the
power exhaust power source.

10. Field-Installed PremierLink Control (See Fig. 10): Con-
nect the gray wire from the low voltage extension har­ness to J8-3 and the tan wire to common terminal.
Common is available from PremierLink terminal J1 or
the common side of the unit control power transformer
(the brown leads that go to unit ground). The other end of
the harness is connected to the power exhaust wiring.
NOTE: When the PremierLink board is configured for a
heat pump, it does not require the HS3/EXH/RVS, allow­ing this terminal to be used for the power exhaust.
Factory-Installed PremierLink Control: The Premier­Link J8-3 terminal is factory wired to a terminal board
TB2-15 (Small and Large Cabinet) or TB3-15 (Extra
Large Cabinet) located in the low voltage section to the
left of the control box. The gray wire from the harness
should be routed and wired to TB2-15 or TB3-15. The
tan wire should be routed and wired to the Central Termi­nal Board Thermostat Terminal C (Common).
RTU-MP/OPEN Control: Connect the gray wire from
the low voltage harness extension to J11-3 and the tan
wire to the Central Terminal Board Thermostat Terminal
C (Common).

door): Install the gasketing (provided) on the back of
power exhaust side mating flanges. (See Fig. 11.)
NOTE: This step does not apply to units with a hinged
door.

#10 x

/4 in. long screws provided. Make sure wiring har-

nesses are properly secured. (See Fig. 12.)

5. Locate the aluminum filter shipped with the economizer.
Open the filter clips under the top hood of the power
exhaust. Slide aluminum filter into the outside air open­ing of the power exhaust. Filter will slide past filter clips.
Close filter clips, which will lock filter in place.

6. Reinstall the fan shield.

7. Return power to unit and remove lockout tag.

8. Test power exhaust operation by setting the power
exhaust set point on the economizer controller to 0%.
Power exhaust performance is shown in Fig. 13.

9. Adjust the power exhaust set point on the economizer
controller to the desired activation point per unit sche­matic.

10. For units with a standard filter access panel, reinstall the
unit filter access door.
For units with a hinged access door (Small and Large
Cabinet), install the hinged door seal angle included in
the power exhaust kit using the instructions in this
instruction. Do not proceed unless the sealing angle is
installed. Units with a hinged door that do not have a
sealing angle may not have a watertight seal.

Follow these instructions if the unit has a hinged panel in­stead of a standard filter panel. Hinged Door Angle CRPE­CONV003A00 is for small cabinets and CRPE­CONV004A00 is for large cabinets.

NOTE: A separate hinged door angle kit must be ordered for the
extra-large cabinet.

1. Find the sealing angle and three screws provided in the

power exhaust kit.

2. Attach the sealing angle to the top of the power exhaust

hood using the screws provided. Refer to Fig. 14 and 15.
Note that the gasketing flange will be facing out.

3. If there are NO pre-drilled holes in the Power Exhaust

hood: Lay the hinged panel, insulation side up, on top of
the hood so that the hinge screw holes align with the pre­drilled screw holes in the sealing angle. (For hoods with
pre-drilled holes, skip to Step 7.)

4. Check the alignment of the hinged door with the side of

the filter opening to be sure it will close properly.

5. Use a pencil to mark the hood where the screw holes will

be.

6. Remove the hinged door and drill four (4)

where the marks are.
NOTE: The sealing angle will be in place; use the holes
in it as a guide.

7. Place the door and hinges back on the unit. Screw

through the door hinges and sealing angle into the
flanged top of the hood using the 4 screws set aside when
the hinged door was removed. (See Fig. 16.)

8. Close the hinged door and adjust handle if necessary.

PremierLink™ — Operational Notes for Testing
Purposes

If the “continuous power exhaust” function is disabled, the
power exhaust fan will operate during EconoMi$er purge cy­cles when the EconoMi$er damper position is above the con­figured minimum value. If enabled, the power exhaust fan
will follow the supply fan's operation for PremierLink ver­sion 1.2 and will follow the occupancy configuration for Pre­mierLink version 1.3.

The PremierLink “Auxiliary Output” function defines the
specific use of the auxiliary output (HS3/EXH/RVS) for the
power exhaust. The output will be energized or deenergized
by the appropriate algorithm that uses that specific output.

A setting of 1 = Exhaust fan output.

The Power Exhaust set point in the set point table deter­mines the power exhaust damper “percent open” when the
power exhaust is energized. The damper percentage set point
has a 10% hysteresis.

If “Continuous” in the service configuration table is set to
“enable”, the power exhaust output will energize when occu­pied (for PremierLink controls version 1.3 and later) and will
be energized when the supply fan relay is on (for versions pri­or to 1.3).
