United HVAC Motors Manual

IT IS OUR HIGHEST HONOR TO PRESENT THIS REMANUFACTURED MOTOR TO YOU!

YOU MUST READ THIS MANUAL IN ITS ENTIRETYFAILURE TO DO SO WILL VOID WARRANTY.

This motor has been remanufactured to the original specifications using ONLY the highest quality OEM parts available. We remanufactured this motor “to order” immediately before shipping. It was then tested using the manufacture’s computer program for 4+ hours and read PASS/OK on all 34 tests.For some reason if the item is not working for you – please make sure to review entire manual. If you are still having problems, we have a dedicated technical support staff available to help you get the motor running. We will run you though the steps listed in the manual.Need help installing or technical questions?

Replacing the ECM Control Module (X13 Only)

Before replacing the electronic-control module, you must test the motor module to ensure it is not also damaged. Installing a new control on a failed motor will result in no operation, improper operation and/or potential failure of the new control. Procedures for testing the motor module is included below.

Disconnect AC power from the HVAC system.Carefully notate which wires you removed and where they were attached to.

ONLY after the system AC power has been off for 5 minutes, remove the two (2) hex-head screws from the back of the control. Unplug the 3-pin connector from the inside of the control by squeezing the latch and gently pulling on the connector you’re ready to test the motor. (See Figure to Right)

MOTOR MODULE TESTS

A. The Winding Test

Set ohm meter to the highest possible setting and measure resistance between each of the three motor leads to the unpainted part of the end shield (or x-brace on model Eon & 3.0).The motor passes the test if the meter indicates greater than 100k ohms. (See Figure to Right)

B. The Phase-to-Phase Test (see Figure 6 below)

A. The Winding TestSet ohm meter to lowest possible setting and measure the motor phase to phase resistance by checking these combinations of the 3-pin motor connector with an ohm meter: (See Figure to Right)

Lead 1 to lead 2

Lead 1 to lead 3

Lead 2 to lead 3

For the purpose of this test, either end of the 3-pin plug is lead 1. Resistance values should be less than 20 ohms and each of the three values should be the same (plus or minus 10%). If the measured resistance is outside of these parameters, the motor fails the test.

1/3 HP Approximately 22.7 Ohm1/2 HP Approximately 13.5 Ohm3/4 HP Approximately 7.8 Ohm1 HP Approximately 5.8 Ohm

C. If the motor passes both of these tests and the shaft spins freely when rotated by hand,then the motor is ok and only the module must be replaced.

D. If the motor fails either of these tests or does not spin freely when rotated by hand,replace the motor and control module (CALL US AT 813-440-8108 to order a motor). Insert the 3-pin connector back into the new control module. A slight click will be heard when inserted properly. This connector is keyed for proper connection.

Attach the new control module with the plug connections oriented down insert the appropriate bolts and tighten. Due to model replacements, some motors may need to be rotated in their mount to orient the plug connectors properly.

Reconnect AC power from the HVAC system. Carefully replace wires you removed to where you notated they were attached to.

The connectors are keyed.

Observe proper orientation. Be certain to form a drip loop so that water cannot enter the motor by draining down the cables (See Figure to Right)

HOW TO REVERSE MOTOR (3-Phase DC Motor)

  1. Turn off Breaker
  2. Remove Module from Motor
  3. Identify 3 Wires from Motor to Module
  4. Cut Red & Black Wires (Switch them)
  5. Use Butt Splices to Reattach Reversed
