CSR Motor Wiring Diagram:

Electrtic Motor Type: The type of motor being used in the ULTRA-2 HP dispenser is known as CSR motor (Capacitive Start & Run).

The CSR version uses a start and run capacitor with an external thermal protector. The start capacitor is in series with the compressor motor start winding. A potential starting relay coil is wired across the start winding which can sense change in voltage. The start- ing winding voltage will increase along with motor speed. When the voltage has reached a point, the re- lay contacts will open, de-energizing the start winding capacitor.

Capacitor Ratings:

Start Capacitor: 243-292 MFD 165V 50/60HZ

Run Capacitor: 35 +/-5% MFD 425V 50/60HZ

Refrigerant Charge:

Type: R404A

Amount: 11 oz.

Design Pressure: High 430 & Low 80
