Making a good crimp Good crimps are essential for a long-lasting, reliable installation. There are many informative guides, videos and tool recommendations on the internet. Please consult this excellent reference if you are unfamiliar with crimping connectors or need to purchase a tool. Moderately tug on the crimp joint after making your crimp to be sure the joint was properly made. If the wire pulls out, the joint was not done correctly and must be redone.

Mach 1, 3, 3+, 10, 15 Mach 1, 3, 3+, 10, 15 high profile models Wiring diagram A Coleman AC may be factory configured four different ways as shown in the factory diagram above. The dash outlined block on the left where EasyStart is connected shows a PTCR and start capacitor. The right dashed block shows a start relay configuration. The dashed components inside each block show that those components may not be installed in either configuration. There may be 2 or 3 capacitors inside of the electric box.

Mach 1, 3, 3+, 10, 15 Mounting locations Figure 1 The blue arrows in Figure 1 above show possible mounting locations. This can vary depending on how the tubing is run in this part of the air conditioner. Use the double-sided tape included in the optional installation kit to secure EasyStart to the Air Conditioner. The wire exit should be pointing down or the box should be mounted parallel to the bottom of the cabinet. Clean and dry the selected mounting area.

Mach 1, 3, 3+, 10, 15 Identifying the wires The blue arrow to the left points to the top of the compressor. Three wires exit this cap colored BLACK, WHITE, and RED shown entering the electric box by the green arrow. Figure 3 Making the connections Use only end splice or jacketed spade connectors for connecting one wire to another. Wire nuts can come off in this high vibration environment and automotive connectors are not rated for line voltage.
PAGE 7
Mach 1, 3, 3+, 10, 15 White wire Place a yellow female quick-connect terminal on the WHITE wire from EasyStart and crimp tightly. Connect the WHITE wire from EasyStart to the run capacitor on the same terminal group as the yellow wire indicated by the yellow arrow in figure 6. Figure 6 Orange wire Place a blue female quick-connect terminal on the ORANGE wire from EasyStart and crimp it tightly. Connect the ORANGE wire to the red wire terminal group on run capacitor shown by the orange arrow in figure 7.
PAGE 8
Mach 1, 3, 3+, 10, 15 Black wire Follow the black wire from the compressor into the electrical box to where is connects to the purple wire pointed to by the orange arrow in figure 8. There is an end splice connector located at the junction of these two wires. Cut off this end splice connector. Strip about ½ inch (1.27cm) of insulation from both the black and purple wires. Strip ½ inch (1.27cm) from the BLACK wire from EasyStart and twist the three wires together.
PAGE 9
Mach 1, 3, 3+, 10, 15 Removing existing start components Some systems may use a start cap (orange arrow in figure 10) and PTCR (green arrow in figure 10). Previous owners may have also installed a hard start kit that replaces these components. These components form a circuit that connect from the yellow wire side of the run capacitor to the red wire side of the run capacitor. Figure 7 shows a single red wire connecting to the run capacitor.

Mach 8 Mach 8 low profile models. Model identification and wiring diagrams Two slightly different models of low-profile air conditioner were produced. They are identified here as style 1 and style 2. Diagrams are normally installed on the electric box inside cover. Style 1 Figure 11 shows the early model low profile unit. The picture is shown with the fan removed for easier access. Capacitors are mounted inside the metal box in the center of the AC unit.
PAGE 11
Mach 8 Style 2 Figure 13 shows a later low-profile unit. The capacitors are mounted outside the box as indicated by the blue arrow in the figure. Wiring connections to EasyStart will all be made inside the electric box in the center of the unit just under the fan. Figure 14 shows the wiring diagram shipped with this unit and modified to show EasyStart.

Mach 8 Mounting location Figure 20 The red arrows in Figure 20 show suggested mounting locations. Removing the fan will give better access to wiring and mounting. Clean and dry the selected mounting area. Use double sided foam tape provided in the installation kit to secure the enclosure to the air conditioner in one of the identified areas. 12 ©2022 Micro-Air Rev 1.

Mach 8 Identifying the wires (Style 1 and Style 2) The blue arrow to the left points to the top of the compressor in Figure 21. Three wires exit this cap colored BLACK, WHITE, and RED. These wires enter the electric box as shown by the green arrow in Figure 16. The connections these wires make inside the electric box will be used to connect EasyStart in the next installation steps.
PAGE 14
Mach 8 Making the connections Use only end splice or jacketed spade connectors for connecting one wire to another. Wire nuts can come off in this high vibration environment and automotive connectors are not rated for line voltage. Style 2 1 2 4 3 5 6 Figure 22: Style 2 electric box Brown wire Follow the white wire from the compressor into the electric box. Continue to follow the wire to the connector block and unplug the wire from the connector block (see arrow 2 in Figure 22).
PAGE 15
Mach 8 Disconnect the start capacitor If your unit has a start capacitor is must be disconnected. Not all units have start capacitors so first determine if your unit has one. Follow the red wire from the compressor into the electric box (arrow 5 in Figure 22). If this wire leads to a PTCR you have a start capacitor that must be removed. If you do not have a start capacitor, you can continue to the next step placing the orange wire. First locate the start capacitor.
PAGE 16
Mach 8 Style 1 1 2 3 4 5 6 7 Figure 23: Style 1 electric box Brown wire Follow the white wire from the compressor into the electric box. Continue to follow the wire to the run capacitor (arrow 1 in Figure 23) and unplug the wire from the capacitor. Install the yellow male quick connect on the BROWN wire from EasyStart and crimp the connector. Connect the unplugged white wire into the BROWN wire from EasyStart.
PAGE 17
Mach 8 Disconnect the start capacitor If your unit has a start capacitor is must be disconnected. Not all units have start capacitors so first determine if your unit has one. Follow the red wire from the compressor into the electric box (arrow 2 in Figure 23). If this wire leads to a PTCR (pointed to by arrow 3 in Figure 23) you have a start capacitor that must be removed. If you do not have a start capacitor, you can continue to the next step placing the orange wire. First locate the start capacitor.

Other Models Other Models There are a few other models of Coleman air conditioners we should mention. The process of wiring them is comparable to the Mach 1 and similar units. Use these diagrams along with the component identification shown in the Mach 1 section to identify and connect EasyStart. Wiring colors are the same with all models we have come across so far.
PAGE 19
Other Models Polar Cub #1 Outdoor Temp Board Only This instruction is for units without start components. If the run capacitor has more than one red wire on the run capacitor as shown below, please use figure 33. The red X by the run capacitor indicates the white wire is disconnected from the white/yellow wire terminal group and reconnected to the BROWN wire from EasyStart using a splice joint. The white wire (shown in blue for contrast) is connected where the compressor white wire was removed.
PAGE 20
Other Models Figure 31 shows the outdoor temperature relay board. The black wire on the relay shown by the orange arrow is the wire of interest on the N.O. connection in the schematic of Figure 30, to which the EasyStart BLACK wire will connect. First, disconnect the black wire from the relay. If the connector on the existing black wire is unjacketed, cut it off and crimp on tightly a blue female connector as it is in Figure 31.
PAGE 21
Other Models Pressure Switch Relay – with or without components on Pin 7 These models have a pressure switch relay that the compressor black wire connects to. A typical schematic is shown in Figure 33. Red X indicates wires and components that are to be removed. Not all systems have these components. If the run capacitor has only a single red wire on the terminal group opposite the white/yellow wire group then there are no start components.
PAGE 22
Other Models Figure 34 shows the pressure switch relay by the green arrow and a different angle in Figure 35. The black wire on the relay shown by the orange arrow in Figures 34 and 35 is the wire of interest on the Pin 2 connection in the schematic of Figure 33, to which the EasyStart BLACK wire will connect. First, disconnect the black wire from the relay. If the connector on the existing black wire is unjacketed, cut it off and crimp on tightly a blue female connector as it is in Figure 34.
PAGE 23
Other Models Polar Cub #2 This version is an alternate wiring supplied with some models. The red X’s in the PTCR, start capacitor, YEL, and RED wires are all components that must be removed if they are installed. Not all systems have these components. If the run capacitor has only a single red wire on the HERM terminal or a single red wire on the terminal group opposite the white/yellow wire group then there is no start components its red X’s can be ignored.
PAGE 24
Other Models TSR Mach 3 The TSR Mach 3 is an older model that is still similar to other models here. The diagram is included because it is drawn visibly different from the other models. The wiring is however the same. Figure 37 24 ©2022 Micro-Air Rev 1.
PAGE 25
Other Models High efficiency two ton This unit is actually two compressors in one box therefore two EasyStart units are required. The box is typically “basement” or under coach mounted. As with other models, start components are removed by removing the red and yellow wires from the run capacitor that go to the PTCR and start capacitor. Figure 38 25 ©2022 Micro-Air Rev 1.
PAGE 26
Units with Freeze Switch on Compressor Figure 39 shows EasyStart wiring where a freeze switch in a heat pump model is directly connected to the compressor. Red X indicates wires and components that are to be removed. Not all systems have these components. If the run capacitor has only a single red wire on the terminal group opposite the white/yellow wire group then there are no start components.
PAGE 27
Learn process EasyStart “Learns” the start characteristic for your compressor over the first five starts. We recommend that these starts are done on a 20 amp or greater utility power source with all other loads in the RV turned off. Installations that do not have access to utility power can do the learn process on a generator, but with some risk and it is not recommended. Generators must have a continuous rated output capable of supporting the air conditioner.
PAGE 28
Troubleshooting FAQ How do I know I installed it correctly? EasyStart has a few characteristics that can help you determine that. First, the compressor should start more quietly than it did before. Lights will dim much less and if you have a volt or current meter you should see a measurable difference. Second, if you turn off the compressor at the thermostat when it is running then turn it on right away, EasyStart will prevent the compressor from starting for five minutes.
