The following are the Taylor-recommended settings for
various components within these models. The Model
C152 and C161 uses R404A.
Expansion Valve—Low Side (Suction)
Soft Serve
C152—Air-Cooled: 20 to 22 psi (138-152 kPa) for a
normal product of 16°F to 18°F (-8.8°C to -7.7°C).
C161—Air-Cooled: 21 psi (145 kPa) for a normal product
of 16°F to 18°F (-8.8°C to -7.7°C). Set each side
separately at 15 psi to 16 psi (103 kPa to 110 kPa).
C161—Water-Cooled: 21 psi (145 kPa) for a normal
product of 16°F to 18°F (-8.8°C to -7.7°C). Set each side
separately at 15 psi to16 psi (103 kPa to 110 kPa).
Expansion Valve Adjustment
1. Place your gauge on the access valve on the suction
line (located at the compressor).
2. Adjust the pressure higher or lower by turning the
adjustment screw. Clockwise turns raise the
pressure, and counterclockwise turns lower the
pressure.
3. Make expansion valve adjustments with mix in the
cylinder and with the freezer in the Auto mode. Allow
adequate time for the pressure to stabilize.
4. For Model C161, repeat this procedure for the other
side of the machine. The expansion valve on each
side of the machine must be set separately.
Expansion Valve—High Side (Discharge)
High side pressure varies for air-cooled machines
depending on the ambient temperature.
