The Micro-Air EasyStart is a device designed to mitigate the high startup current demands of air conditioner compressors. Installation requires careful attention to wiring and component identification, and may necessitate replacing triac switches with relays in certain applications. This article details the installation process, wiring procedures, and initial setup based on available documentation. The EasyStart is suitable for installation by professional HVAC technicians, RV shop personnel, or experienced DIY homeowners.
Understanding the EasyStart System
The EasyStart device aims to reduce stress on compressors during startup, potentially extending their lifespan and enabling operation on limited power sources like generators. Improper installation can lead to damage to the EasyStart itself, the compressor, or related electrical components. Therefore, a thorough understanding of the installation instructions is crucial. The documentation emphasizes the importance of disconnecting power to the compressor’s electrical system before beginning any work.
Identifying System Components
Prior to installation, users must identify key components within the air conditioning system. According to the provided documentation, these include:
- The start capacitor, typically housed in a plastic container.
- The run capacitor, typically housed in a metal container, with two or three terminal connections.
- The start relay or compressor start device, which may not be present in all systems.
- The control board switched-L1 output or the main contactor compressor L1 output, which connects to the compressor common.
Consulting the manufacturer’s installation manual and wiring diagram is essential for accurate identification of these components.
Wiring Procedures
The installation process involves connecting several wires from the EasyStart to the existing electrical system. The following steps outline the wiring procedure, as detailed in the provided documentation:
- Connect the white wire from the EasyStart to the same terminal on the run capacitor as the existing white (run winding) wire.
- Connect the orange wire from the EasyStart to the terminal on the run capacitor that connects to the compressor start winding, typically labeled "COMP", "C", or "H". This terminal often has orange or pink wires connected to it.
- Connect the black wire from the EasyStart to the switched-L1 connection from the control board or main contactor, which typically has a black or purple wire connected to the compressor common (C) terminal.
- Remove any unused or disconnected wires and close all electrical boxes and panels.
Important Installation Considerations
The documentation highlights a critical consideration regarding systems utilizing a high-current triac to switch power to the compressor. In such cases, the triac must be replaced with a relay. Failure to do so can result in damage to both the EasyStart and other connected devices. A compatible replacement relay is available from the Micro-Air webstore.
Mounting the EasyStart
Once wiring is complete, the EasyStart unit must be securely mounted. The device features four mounting holes on its flange. Mounting options include double-sided foam tape, screws, and zip ties. Caution is advised when using screws or drilling, as refrigerant tubes can be easily punctured. The unit should be located close to the original system’s electric box, considering the length of the wire harness.
Initial System Startup and Learning Mode
After installation and mounting, the system circuit breaker should be turned on. A heating or cooling cycle should then be initiated using the thermostat. The EasyStart will automatically enter a learning mode during the next five start cycles. This process does not require any user intervention and is performed during normal operation. Once the learning process is complete, the EasyStart can operate on either shore power or generator power.
Bluetooth Connectivity and App Usage
The EasyStart can be connected to a smartphone via Bluetooth using the EasyStart Bluetooth App. The connection process involves the following steps:
- Turn on the air conditioner.
- Type “EasyStart_” (with capitalized E and S) into the app.
- Tap “done” or “return”.
- Tap the “Connect to EasyStart” button. The app will automatically locate and populate the EasyStart’s unique ID.
Users are advised to record the new ID number for future reference. The app also provides access to features such as Flex installation instructions and the relearn function.
Compatibility with Various Air Conditioner Models
The provided documentation lists several air conditioner models with which the EasyStart has been successfully installed or tested. These include:
- Air Force RCSS6000U(16K) Portable AC
