Introduction
Running Specifications
Expansion Valve Setting
R404A
340--12: 38 -- 39 PSI (262 -- 268 kPa.)
340--27, 341 & 342: 35 -- 36 PSI (241 -- 248 kPa.)
Low Side Pressure
Low side pressure = expansion valve setting.
To adjust the low side pressure, place the gauge on the
low side suction port at the compressor . With the
compressor running, turn the adjustment knob of the
automatic expansion valve clockwise to raise low side
pressure and counterclockwise to lower pressure.
High Side Pressure
Air Cooled: The following chart indicates normal
operating head pressures at various ambient
temperatures:
Ambient Temperature Normal Operating Head
Pressures
F. C. PSI
70_ 21.1_ 240 -- 270
(1,655 -- 1,862 kPa.)
80_ 26.7_ 270 -- 300
(1,862 -- 2,069 kPa.)
90_ 32.2_ 300 -- 340
(2,069 -- 2,344 kPa.)
100_ 37.8_ 340 -- 380
(2,344 -- 2,620 kPa.)
E.P.R. Valve Setting (Dairy Un its, Only)
38 -- 40 PSIG (262 -- 276 kPa.) for normal product at
temperatures of 27_ to 30_F(--2.8_Cto--1.1_C).
1 PSI (7 kPa) lower for every 2_F(1.1_C) colder
product.
1 PSI (7 kPa) higher for every 2_F(1.1_C) warmer
product.
Note: If product in the freezing cylinder contains
alcohol (liquor) the expansion valve pressure setting
may have to be reduced approximately 10 PSI (70
kPa) to attain the desired product consistency. It may
be necessary to reduce the pressure setting further,
depending on the level of alcohol content.
