Removing and Installing Staggered Coils
Staggered coils have two banks of coils positioned a few
inches apart in the direction of airflow. Both coils are secured
to the unit on the connection and opposite connection end of
the unit.
1. Disconnect all piping and remove the brass plugs for the
vents and drains located in the connections.
2. Panels on both the connection and opposite connection
end of the coil section need to be removed to access bolts
holding the coils in place. Each coil is held in place with
bolts located in the corners of the coil side plates. Remove
the bolts then lift and pull the coil out the side.
3. The bottom coil is fastened to the air block off plate. The
screws attaching this plate to the coil must also be
removed. Once fasteners holding the coil in place are
removed, the coil can be pulled out either side of the unit.
4. Install coils in reverse order of removal.
