TOSOT TS-H246JAL3
Electrical Schematic & Connection Guide
Since this is a single-phase ($1\phi$) unit, the electrical system relies on a Permanent Split Capacitor (PSC) motor. Below is the technical breakdown of the wiring logic for this 2-ton TOSOT unit:
- Compressor Wiring: * Common (C): Connects directly to the Overload Protector (Internal).
- Start (S): Connects to one side of the 50 $\mu$F Capacitor.
- Run (R): Connects to the Neutral line and the other side of the capacitor.
- Outdoor Fan Motor: Usually wired in parallel with the compressor power supply, using its own smaller capacitor (typically 5-7 $\mu$F).

Engineer’s Notice & Field Advice
- T3 Climate Advantage: This unit is rated for T3. As an expert, I recommend ensuring the outdoor unit has at least 50cm of clearance from any wall. T3 units move a massive amount of heat; restricting airflow will cause the amperage to spike above the rated 10A, leading to premature winding failure.
- Capacitor Maintenance: The 50 $\mu$F capacitor is the most common point of failure. If the compressor hums but doesn’t start (drawing high LRA), check the capacitor before condemning the compressor.
- Charging by Weight: Since the system uses 1.8 Kg of R22, always charge using a digital scale. Overcharging an R22 system in a T3 environment causes liquid slugging and destroys the valve plates.
