Tjernlund 950-0625 SS1 Motor Kit 8504016 Rev. A 11/99 - Manual

MODEL (950-0625) SS1 REPLACEMENT MOTOR WITH WHEEL KIT INSTRUCTIONS
Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage.
IMPORTANT:
Motor replacement will depend on which of the three date code periods the SideShot was manufactured during. For SideShots with
date codes prior to “9226”, (black FASCO motor with 2 wire leads), design enhancements have made replacements of these motors
obsolete. It is necessary to replace the entire Plenum Section part # 950-0670 which includes the motor and electrical controls.
SideShots with date codes after “9518”, (gray MAGNETEK motor with 2 wire leads)
For the steps following below, refer to diagram A.
1. Remove electrical box cover and disconnect (2) motor leads.
2. Remove and save (1) motor bracket screw from electrical box.
3. Holding the motor, apply firm pressure towards the plenum of the SideShot and
remove and save the (6) motor mount nuts. Note: Hold the assembly firmly;
failure to do so could damage internal parts.
4. Slide motor/wheel assembly from Plenum. Grasp only the motor casing;
do not damage wheel, shaft or other components on Plenum. Do not rest
assembly on wheel.
5. Install new motor/wheel assembly into Plenum with leads facing electrical box. Use caution when inserting motor/wheel
assembly into Plenum to avoid wheel damage. Firmly fasten motor to plenum using (6) nuts removed in step 3 above.
6. Route wires from motor into electrical box. Slip BLACK onto terminal “M” and WHITE onto terminal “L2” of terminal strip.
7. Reinstall (1) motor bracket screw removed from step 2 above.
8. Reestablish power and run SideShot through heating cycle to verify proper operation.
SideShots with a date code between “9226” and “9517”, (gray MAGNETEK motor with 3 wire leads)
For the steps following below, refer to diagram B.
1. Remove electrical box cover and remove (3) motor leads.
2. Remove and save (2) motor & electrical box brace screws.
3. Remove and save (2) nuts from inlet collar on
housing inside plenum. Note: Removal of plenum
access cover plate will allow for removal of inlet
collar nuts with 11/32” box end wrench.
4. Push down electrical box about 1/4” so motor mount plate
can clear junction box. Once motor mount plate has
cleared the studs it can be rotated so motor mount plate flat
aligns up with junction box for easier removal.
5. Holding the motor, apply firm pressure towards the
plenum of the SideShot and remove and save the (6)
motor mount nuts. Note: An 11/32” box end wrench
is used for nut directly under electrical box. Note:
Hold the assembly firmly; failure to do so could
damage internal parts.
