Introduction The imPower motor is a permanent magnet alternating current (PMAC) electronically commutated motor (ECM), leveraging over 20 years of ECM technical and manufacturing experience. The PMAC machine is inherently more efficiency than its induction counterpart, resulting in energy consumption savings of up to 85%. This imPower motor is designed to safely replace existing full-rated pool filter pump motors rated at 3/4 HP 1.65SF or up-rated motors at 1.0HP 1.25SF.
Operation imPower motors are configured with Constant Speed, meaning they simply maintain the speed (RPM) they are configured for in each application. This reduces the effect filter cleanliness and product load have on the operation of the motor, unlike traditional induction motors. The motor only uses the power (current) necessary to operate at its programmed speed, and has the ability to automatically increase or decrease power to maintain that speed.
Installation and service of this motor should be attempted only by trained service technicians familiar with the Evergreen instructions and training manual. This motor should be installed in accordance with accepted practices and installation instructions, and in compliance with all national and local codes. Remove the Existing Motor from Pump When servicing the pool pump filter motor, always disconnect the main power from the unit. It is also good practice to confirm the power is off with a meter.
Topside Interface Overview The topside interface on the imPower motor provides functionality to change amongst three distinct preset speeds via either a button press or by a remote timer / automation controller. Green display LED’s will light to indicate the currently selected speed as well as to indicate power is applied to the motor. A red Error LED is also included to show a fault identified by the on-board diagnostic system.
Installation and service of this motor should be attempted only by trained service technicians familiar with the Evergreen instructions and training manual. This motor should be installed in accordance with accepted practices and installation instructions, and in compliance with all national and local codes. Single Speed Connection with Timer Always disconnect the main power from the unit prior to servicing the pool pump filter motor.
Step 7: Carefully fold the extra wires inside the terminal box and place the top control panel back on top of the terminal box. Step 8: Tighten the three screws into the terminal box while applying light pressure to the top control enclosure. Step 9: Replace and tighten the screws to mount the seal plate onto the motor. Step 10: Put a NEW pump seal into the seal plate and onto the motor shaft. Handle and lubricate seal per manufacturer’s specifications. Step 11: Replace the impeller.
3. The user can override the operational speed currently running via the buttons on the top control panel after the mandatory initial two-minute prime cycle. The override will continue until the timer removes power or another button is pressed. The standard operation identified in Note 1 can be resumed if the power is turned off at the timer and turned back on.
Installation and service of this motor should be attempted only by trained service technicians familiar with the Evergreen instructions and training manual. This motor should be installed in accordance with accepted practices and installation instructions, and in compliance with all national and local Speed codes. Connections with Timer Two Always disconnect the main power from the unit prior to servicing the pool pump filter motor. It is also good practice to confirm the power is off with a voltage meter.
Step 5: Remove the three screws holding the top control enclosure onto the motor. Carefully lift the top panel and turn it over to expose the inside of the terminal box. Step 6: Run the High Speed Black, Low Speed Red, L2, and Ground wires from the conduit cable through the opening on the right side of the motor. Step 7: Connect the wire for Circuit 1 from the timer to the opening directly across from the BLACK wire on the terminal block (refer to Figure 10).
Step 16: Replace the impeller. Make sure that the impeller can spin freely in the housing. Step 17: Replace the diffuser. Step 18: Replace and tighten the bolts that retain the motor/seal plate assembly to the pump. Step 19: Connect the appropriately sized ground conductor to the supplied grounding/bonding lug. Step 20: Open the inlet and outlet valve.
Installation and service of this motor should be attempted only by trained service technicians familiar with the Evergreen instructions and training manual. This motor should be installed in accordance with accepted practices and installation instructions, and in compliance with all national and Automation local codes. Controller Signal Line Connection Always disconnect the main power from the unit prior to servicing the pool pump filter motor.
Figure 13 Step 9: Figure 14 Plug the connector end of the low voltage cable (P/N 391-200-01 or P/N 391-200-02) into the connector on the underside of the top control enclosure as seen in Figure 13. Step 10: Carefully fold the extra wires inside the terminal box and place the top control panel back on top of the terminal box and tighten the three topside enclosure screws. Step 11: Carefully pull the low voltage cable to reduce the amount of excess cable inside the connection box.
Step 13: Wire the low voltage cable to the automation controller. The speed connections and their corresponding lead colors are shown in Figure 17. The (+) marking denotes the positive side controller connection and the (-) denotes the negative side controller connection. High Speed: BLACK (+) WHITE (-) Medium Speed: BROWN (+) BLUE (-) Low Speed: RED (+) GREEN (-) Figure 17 Step 14: Replace any access panels on the controller that were removed.
Notes: 1. The automation controller allows for the programmable operation of all three speeds. The motor will start on high speed for each speed selection and operate through its two-minute prime cycle before reacting to any controller inputs. The on time and speeds should be set so that the pool can meet the total number of turns as required by local/ state regulations. 2.
Automatic Reduced Speed Selection The imPower motor has been programmed with a feature called the Automatic Reduced Speed Selection function that allows for the maximum energy savings via multi-speed operation despite using a standard single-speed timer. This feature also applies to a multi-speed timer where the Circuit 2 speed can either be assigned to medium or low speed. The reduced default speed is factory set to switch to low speed operation after the initial two-hour high speed operational period.
Default Reduced Speed Operation: 1. For a standard single speed timer connection, the motor will run high speed for the duration of the two hour initial operation. After this time period, the speed will convert to the new default speed. 2. For a modified single speed timer connection, the motor will run high speed for the duration of the two-minute initial operation. After this time period, the speed will convert to the new default speed. 3.
Software Error Code Matrix The imPower control panel has a red error display LED to indicate operation issues. Normal operation is indicated by a single flash of this LED upon startup. Any subsequent blink sequence of this LED indicates that a fault has been registered by the motor control, with the explanation of these faults given in the below table. This table also includes the cause for this fault as well as some potential actions to potentially resolve the issue.
Blinks Faults Software Cause Action 6 Output shaft seized Motor failed to start. Motor was stopped. - Manually rotate the shaft via the shaft access in the fan cover - Inspect all equipment in-line with the pump for obstructions or locked pump parts. 7 Self check One or more of the self-tests failed either at start up or while running. - Turn the power off at the timer / breaker and allow motor to remain off for at least 15 minutes before reapplying power.
Troubleshooting Guide 1. Issue: Motor will not automatically turn-down to the reduced speed after two hours when connected to a single speed timer. Action: Any command to change speeds after the initial mandatory twominute prime cycle will over-ride the automatic turn-down function. Turn the motor off at the timer / breaker, wait one minute, then turn the power back on. The software will have reset in this time and should operate as required. 2.
5. Issue: Insufficient flow from water features Action: Assuming this issue was not pre-existing, the programmed low speed on the imPower likely does not provide sufficient flow / pressure to provide desired water feature action. Change the speed to medium and determine if this solves the issue. If it does, change the default reduced speed to medium per the appropriate procedure outlined in this guide. 6.
