Safety and Warnings      AC Power can be dangerous or lethal if the proper safeguards are not understood or performed. If you are not sure of any aspect of this installation or proper safety when working with AC line voltages, please seek installation by a qualified HVAC or electrical professional. Turn off all power to the air conditioning system before proceeding. Read all instructions before starting installation.

Section 1: Installing EasyStart in most systems Step 1: Identify the components Run capacitor Contactor Figure 1 The two components shown in figure 1 will be used to connect your EasyStart. Locate these components in your air conditioner before proceeding. Some compressors will have additional components and may have a circuit board as well. Power comes in from the bottom of the contactor usually from a breaker or fuse panel on the dwelling.

Step 3: Identify the capacitor terminals Three terminal run capacitors HERM FAN C Many compressors have three Figure 2 terminal group capacitors as shown in figure 1. These capacitors feature labels on the top as indicated by the arrows above. Use the labels on these capacitors to identify where to make connections. Two terminal run capacitors Wire to contactor and capacitor Two terminal group caps are harder to identify the terminals because they are not labeled.
PAGE 5
Step 4: Removing start devices HERM terminal group There is only a single yellow wire connected to the HERM terminal in figure 4. Compressors with only one wire on the HERM terminal have no start components and can go on to the next step. If you find there is more than one wire on this group, you will need to identify which of these wires, if any, goes to a start device. Figure 4 One wire will always go to the compressor which you can verify using your factory wiring diagram or tracing them out.

Step 7: Connecting the BROWN wire Follow the wire that connects the C terminal on the run capacitor to the contactor. Disconnect the compressor “R” terminal wire located on the same side of the contactor. This wire is often a heavy gauge wire connected to the screw part of the contactor. It may also be on a quick connect as shown in figure 5. Connect the disconnected wire to the BROWN wire from EasyStart. Connect only these two wires together and not to anything else.

Step 9: Connecting the BLACK wire Contactors are “split” into two electrically separate halves with each half connected to a single voltage line of the incoming service. The red wires are both connected to one side of the contactor in the picture below and the black wires are connected on the other side of the contactor. The wire colors may be different in your installation.

Section 2: Comfort Alert control board systems Goodman GSCZ, Rheem RARL, Goodman GSXC and possibly others Step 1: DISCONNECT ALL POWER Step 2: Disconnect the red wire pointed to by the green arrow in figure 1. Pull it back out through the transformer pointed to by the blue arrow. Step 3: Thread the white EasyStart wire back through the transformer like the red wire that was removed and connect it to the connection terminal.

Step 4: Connect the disconnected red wire to the EasyStart brown wire using an end splice joint. Step 5: Connect the black EasyStart wire under the screw pointed to by the yellow arrow in figure 3. Figure 4 Step 6: Connect the orange wire to the terminal on the run capacitor indicated by the orange arrow in figure 4. Figure 5 ©2021 Micro-Air corp. 9 rev. 1.

Appendix 1: Compressor monitoring system changes This section details changes that should be made ONLY if you have a compressor monitoring system. These systems typically consist of a circuit board located inside the electrical box that incorporates LED’s or a display to indicate a fault. There should be an instruction in the electric box that shows the meaning of the faults. If you do not have such a board or have a board without LED’s or have no such instruction sheet, do not make these changes.

Models with Bluetooth See above appendix 1 description before performing this step. Bluetooth models must be connected to power to disable the starting delay before installation. Turn off the breaker to the air conditioner. Connect the black and white EasyStart wires to the line input side of the contactor indicated by the yellow arrows in figure 8. Tape or wire nut the EasyStart brown and orange wire ends so they cannot make electrical contact with anything. Turn on the breaker to the air conditioner.

Appendix 3: Maintenance The box and entry are water tight and can withstand normal rain events. The box should not be pressure washed since it is not rated for high power water jet cleaning. It can be washed with a mild soap and water solution.
