- Installing the New Atlas Motor
- Removing the Old Motor
- 1 Disconnect motor wires in the junction box. Mark wires in junction box so that you can be sure of connecting the new motor correctly.
- 2 Remove the belt.
- 3 Disconnect motor conduit at the expansion union. Refer to Figure 1.
- 4 Remove the two shoulder bolts on the bottom of the motor deck plate. Remove the washers, cupped washers and rubber mounts. Refer to Figure 2. Retain all hardware.
- 5 While place something underneath the motor to prevent it from dropping suddenly, remove the two flanged screws from the top of the motor deck plate, and retain the hardware.
- 6 Remove the motor from the unit.
- 7 Remove the motor from the motor deck plate and retain the hardware.
- Installing the New Motor
- 1 Attach the new motor to the motor deck plate and tighten the four nuts.
- 2 Transfer the motor conduit from the old motor to the new.
- 3 Insert the motor and deck plate assembly into the unit.
- 4 Thread the motor wiring through the conduits into the junction box.
- 5 Insert the two flanged screws through the slots in the top of the deck plate through the clinch- nuts on the pump mounting plate flange.
- 6 Replace the rubber mounts, cupped washers and washers and the shoulder bolts in the slots on the bottom of the deck plate and thread the shoulder bolts into the clinch-nuts in the bottom frame plate.
- 7 Connect the expansion union and tighten the conduit.
- 8 Attach the new motor pulley to the motor shaft, align it with the pump pulley and tighten.
- 9 Using the proper tool, such as a crow bar, lift the motor up and place the new belt onto the pulleys.
- 10 Using the proper tool, such as a crow bar, push the motor down enough to adjust the tension on the belt to 45 lbs. If tension gauge is unavailable, adjust the tension until there is about 1/2 inch of play midway between the pulleys.
- 11 Tighten the two screws on the top of the deck plate.
- 12 Tighten the two shoulder bolts on the bottom of the deck plate.
- 13 Check belt alignment and tension. Readjust, if necessary.
- 14 Connect the motor wires in the junction box.
- 15 Ensure that the voltage on the motor is set correctly by checking the motor power select switch in front of the motor. Adjust, if necessary. Refer to Figure 3.
- Verifying Performance
- Removing the Old Motor
- Optimizing the Adjustment on the Bypass Spring Preload
- 1 Remove the adjustment cap on the pumping unit. Refer to Figure 4, which shows adjustment cap removed.
- 2 If the amperage from the initial test is low, turn the adjustment screw clockwise and increase the preload (and thus the flowrate and motor load).
- 3 Check the amperage at full flow and at bypass (both must be checked to verify proper loading on the motor).
- 4 Adjust the screw to obtain just below the maximum amperage setting (4.9 amps on a 220-volt system and 9.5 amps on a 110-volt system).
- 5 Replace the adjustment screw cap. Disconnect the amp probe, replace the junction box cover and button-up the unit.
