Replacement Hard Start Capacitor Relay for BOJACK SPP5 - Increases Compressor Torque by 300%

The SPP5 Hard Start Air Conditioner Relay or Capacitor Kit is specifically designed for permanent split capacitor single-phase air conditioning and heat pump systems. Starting capacitors are essential in refrigeration compressors, heat pumps, and other heavy-duty motors that need to be frequently started, providing 300% starting torque.

If your compressor is having trouble starting, consider installing the hard-start capacitor before attempting anything else. Starting an air conditioner or heat pump compressor, whether it's reciprocating or scroll, requires an additional electrical "shock" to kickstart the system. This kit is suitable for heat pump or condenser split systems with (TXV) installed, as well as for older units that have become stuck and non-functional.

When installing, note that the two-wire hard-start kit should be connected in parallel with the run capacitor for Permanently Split Capacitor (PSC) type compressors. For Capacitor Start Induction Run (CSIR) type compressors, connect it to the start and run terminals on the compressor - a third connection to the common wire is unnecessary. Remember to check the model number on the compressor to determine the unit's tonnage.

The package includes one SPP5 Hard Start Air Conditioner Relay or Capacitor Kit, which can save the compressor from aging by boosting starting torque by 300%. This kit is suitable for air conditioner compressors ranging from 4,000 BTU window units to 120,000 BTU commercial units. The motor starting capacitor and PTC thermistor are connected in series, simplifying the installation process with no loose parts or complicated wiring.

This kit is a replacement for various part numbers, including TJSPP5, AP5648661, ERPP5, HS300, HS5, HS520, HS600, MA-XP5, TJ90HS5, and WXS-5. It is widely used in refrigeration compressors, heat pumps, and other heavy-duty motors that require frequent starting.
