Check Rear Door Heat Exchanger Lift Block
Verify the Rear Door Heat Exchanger lift safety block (A) is properly installed and positioned. The lift safety block is located on the inside of the Rear Door Heat Exchanger near the upper hinge. It should be in position under the upper hinge to prevent the door from being lifted off the hinges while connecting or disconnecting the hoses to the RDHx.
If necessary, use the IBM Torque Tool to loosen the screw (B) holding the lift safety block and rotate it into the proper position. Secure the screw tightly.
