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 140
O
F (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.
