3.5 SERVOMOTOR INSTALLATION AND CONNECTION
Your Max Caddy furnace is equipped with a servomotor. You need to secure it in place in the two pre-drilled holes
using two screws as shown below.
Once installed, you need to install the chain that links the air inlet damper to the servomotor as shown below. For
more information regarding this installation, refer to the furnace owner’s manual. The chain that links the air inlet
damper to the motor must have a play of 1/8”and must be secured in place by the hook. When there is no call for
heat, the air inlet damper must be completely closed and the chain must be hooked to the servo-motor at the
“8 o’clock” position (see Detail A and B). This way, the air inlet damper should be about 3/4" open and the chain at
the “10 o’clock” position when there is a call for heat (see Detail C and D). Refer to the electric wiring diagram in
section 7 for the electrical connections.
