    Confused WaterFurnace W2A 4 ton Questions

    3 Questions about this GeoThermal heatpump.

    1. Why is the Low Pressure Safety switch located in the discharge line next to the high pressure safety switch?

    2. After the compressor, and after the Pressure Switches mentioned above the discharge line forms about a 2 foot drop to form a V and then rises to the reversing valve. Is this an oil trap?

    3. or what is the purpose of this and is the reversing valve above the compressor to reduce oil trapping?

    Thanks for your help here. Dan
