DESCRIPTION
The XCOP1 is a Constant Operating Pressure Control that will modulate the speed of an RT-Series Rooftop exhaust fan to maintain a user adjustable negative pressure set point. The set point is adjusted through a pot mounted on the COP circuit board. The
operating range of the XCOP1 control is -0.10 to -1.0” w.c.. Do not use with any other series of Tjernlund Inducers/Venters.
Pressure is measured in a chase or duct at the farthest point from the exhaust fan with the included sensing tube and tubing which
connects to the pressure sensing port on the XCOP1. As exhaust volume increases within the duct/chase the resulting reduction in
measured pressure causes the XCOP1 control to increase power to the fan. It speeds up to handle the additional exhaust volume
and slows down when the exhaust volume is reduced, modulating fan speed to maintain a constant exhaust pressure.
GENERAL INFORMATION
Each XCOP1 is electrically factory line tested before shipment.
After opening carton, inspect thoroughly for hidden damage. If any damage is found notify freight carrier and your distributor
immediately and file a concealed damage claim.
INSTALLATION RESTRICTIONS
1. Do not use the XCOP1 to control the draft of gas or oil fired heating equipment. Draft applications for gas and oil heaters require
the burner interlock of the Draft Cop model DCOP1 controller.
2. The XCOP1 is intended for indoor installation only. Do not mount the XCOP1 on a heat source that exceeds 140OF (60OC).
3. The maximum distance wire can be ran from the RT-Series Fan junction box to the XCOP1 control is 250 feet.
CAUTIONS
The XCOP1 must be installed by a qualified installer (an individual properly licensed and/or trained) in accordance with all local
codes or, in their absence, in accordance with the National Electrical Code. Failure to install, maintain and/or operate the XCOP1
in accordance with manufacturer's instructions may result in conditions which can produce bodily injury and property damage.
1. Disconnect power supply from the XCOP1 when making wiring connections and servicing the XCOP1. Failure to do so may
result in personal injury and/or equipment damage.
2. All installation restrictions and instructions in the RT-Series Fan installation instructions must be followed when using the
XCOP1.
3. Make certain power source is adequate for the XCOP1 and RT-Series Fan requirements. Do not add equipment to a circuit
when the total electrical load is unknown.

SIZING A COMMON VENT MANIFOLD SERVING MULTIPLE DRYERS
The most important step towards assuring that individual dryers vented into a common manifold exhaust smoothly is to size the
manifold large enough to reduce the affects that velocity in the manifold has on the junctions of the dryer vent connections.
Exhaust moving too quickly in a common vent manifold can amplify the exhaust at vent connectors by aspirating across the connector opening and creating an amplified siphon affect. With a properly sized common vent manifold, velocities are maintained
below the point where they have a significant affect on the exhaust of the individual dryer connections.
It is important to note that these sizing recommendations are for the common vent manifold only and that the typically smaller minimum vent diameter listed in the RT-Series Fan selection table may be used for the remainder of the horizontal vent and chimney.
The larger diameter vent manifold should extend at least 2 diameters beyond the last dryer connection point.
1. When in doubt, get help from Tjernlund Tech Service at 800-255-4208, push 0 and ask for technical assistance or email
fanmail@tjfans.com with details of the job.
2. When possible use 45O Manifold Tee connections to the common vent manifold in the direction of the RT-Series Fan instead of
90O Tee connections.
3. If possible, locate larger exhaust volume vent connections closer to the RT-Series Fan. This reduces the affect of their exhaust
on smaller volume connections.
4. The size of the common vent manifold should be at least 90% of the total area of all individual vent connections. See example
below.

Example: A vent layout is required for a job that consists of 3 dryers with 6” diameter outlets.
Add these areas together:
3 x 0.1964 = 0.5892
Total Area = 0.5892 Square Feet x 0.90 (90%) = 0.530. In looking at the table above, this area is greater than an 8" diameter pipe
but smaller than a 10" diameter pipe. 10" diameter vent is the minimum size the common vent manifold diameter should be. It is
perfectly acceptable to be larger than this area if desired. It is also acceptable to have this area be reduced as the vent system
works backward towards the appliance furthest from the RT-Series Fan. In this example, the common vent manifold should extend
at least 20" past the connection point of the dryer farthest from the RT-Series Fan.
XCOP1 INSTALLATION
Do not mount the XCOP1 junction box on a heat source that exceeds 140OF (60OC). Examples of improper mounting surfaces
include vent pipe, top of heater casing or any place where radiant or convective heat would cause the junction box temperature to
exceed 140OF (60OC). The XCOP1 is intended for indoor installation only.
Using the key hole slots on the back of the XCOP1 junction box as a template, mark 4 holes on the mounting surface, drill pilot
holes if necessary, and secure junction box using provided screws.E

PRESSURE SENSING TUBE LOCATION
MULTIPLE DRYERS JOINED IN A COMMON HORIZONTAL DUCT
The sensing tube should be installed in the cap of a tee or at the rear of a common exhaust manifold, in back of the vent connector
that is farthest from the RT-Series Fan. The tee is necessary so that only static pressure is measured, (See Diagram A). If the
pressure sensing tube is installed in the side of a duct it will also measure velocity pressure, giving an incorrect signal back to the
XCOP1 Control. If mounting on the side of the duct is unavoidable, the sensing tube should be flush to the interior wall of the duct.
Avoid sampling near or in elbows. Duct connections should be sealed to prevent leakage or entrainment. Installer must provide
access for lint clean out.

The sensing tube should be installed to sample the chase pressure at a point below the lowest duct connection but above any
point in the clean out that may accumulate moisture or lint. If
sampling pressure in the side of a chase the sensing tube end
should be flush to the interior wall of the chase, (See Diagram B).
Duct connections should be sealed to prevent leakage or entrainment of air. Installer must provide access for lint clean out.

ADJUSTING THE PRESSURE (EXHAUST) SET POINT
1. Verify that slot on set point adjustment pot for the COP controller is aligned with the "20" hash mark, (See Diagram D).
2. Provide power to the XCOP1 by turning on circuit breaker or disconnect or activating dryers if using a dryer duct pressure switch.
3. Verify that the RT-Series Fan activates by seeing the draft pressure increase (more negative) on your draft gauge as measured
with a tee at draft sensing position, (See Diagram E). Gradually adjust the pot on the XCOP1 controller circuit board clockwise.
The RT-Series Fan should speed up increasing the negative exhaust pressure. Slowly adjust the pot on the XCOP1 controller
counter-clockwise until the exhaust pressure is maintained at -0.10" w.c.. NOTE: Turning the adjustment pot too far counterclockwise will cause the RT-Series Fan to stall or not be able to start. Readjust clockwise if necessary.

ADJUSTMENT OF BALANCING BAFFLE(S) FOR KITCHEN AND BATH FANS
IMPORTANT: Balancing Baffles must not be used for dryer applications due to the potential for lint buildup.
1. With all balancing baffles closed and starting with connection at lowest floor drill a small sampling hole in duct connection to the
chase 1 foot behind the Balancing Baffle (opposite side of chase connection).
2. With the XCOP1, RT-Series Fan and Bath/kitchen fans connected to the duct operating, gradually open the Balancing Baffle
until desired negative exhaust pressure is measured and lock in place. Typically a measurement of a -0.02 to -0.05" w.c. is
adequate.
3. Repeat steps 1 and 2 for each floor, moving up towards the RT-Series Fan.
TROUBLESHOOTING ELECTRICAL PROBLEMS
It is necessary to measure voltage during troubleshooting. Extreme caution must be exercised to prevent injury. If you are
unable to determine the defective part with the use of this guide, call your Tjernlund distributor or Tjernlund Products direct at
1-800-255-4208 for further assistance.
RT-SERIES FAN MOTOR DOES NOT OPERATE
Verify the XCOP1 control has power by checking for 115 VAC at the input power terminal strip positions L1 and N. If no voltage is
measured check circuit breaker, disconnect switch or any other switch between disconnect and XCOP1 control.
Voltage present: Verify wiring connections between XCOP1 and RT-Series Fan. Check adjustment pot on XCOP1. Too low of an
adjustment may stall RT-Series Fan. Adjust clockwise to see if RT-Series Fan speeds up. If RT-Series Fan does not speed up and
5
there is 115 VAC across the T6 and T9 terminals on XCOP1 control, verify that RT-Series Fan motor capacitor is good.
Disconnect the wire from capacitor that is connected to the ORG Motor terminal on XCOP1 control. Reconnect Orange wire from
RT-Series Fan capacitor in 4 x 4 electrical box to the Orange wire that should be capped off coming from RT-Series Fan whip.
Remove the Red and White/Red leads that were connected to the MOTOR RED and WHT/RED connection on XCOP1 and provide 115 VAC to them. If motor runs, replace COP control circuit board part number 950-8805. If motor does not run, verify capacitor is good. Replace RT-Series Fan capacitor or motor if necessary.
