INDOOR ENTERING
WET BULB CURVES
TOP TO BOTTOM
71, 67, 63 AND 59 DEG F.
COOLING PERFORMANCE CAN BE CHECKED WHEN THE OUTDOOR TEMP IS ABOVE 55F.
* WHEN USING PRESSURE CURVES TO VERIFY TYPICAL PERFORMANCE, ALWAYS RUN THE SYSTEM WITH ONE OF THE
TEST MODES FOUND IN THE 950/850 COMFORT CONTROL. CHARGING MODE - COOLING.
TO CHECK COOLING PERFORMANCE, SELECT THE PROPER INDOOR CFM, ALLOW PRESSURES TO STABLIZE. MEASURE INDOOR
WET BULB TEMPERATURE, OUTDOOR TEMPERATURE, LIQUID AND SUCTION PRESSURES. ON THE PLOTS, LOCATE OUTDOOR
TEMPERATURE (1); LOCATE INDOOR WET BULB (2); FIND INTERSECTION OF OD TEMP. & ID W.B. (3); READ LIQUID (4) OR SUCTION
(5) PRESSURE IN LEFT COLUMN.
EXAMPLE: (1) OUTDOOR TEMP. 82 F.
(2) INDOOR WET BULB 67 F.
(3) AT INTERSECTION
(4) LIQUID PRESSURE @ 1450 CFM IS 312 PSIG
(5) SUCTION PRESSURE @ 1450 CFM IS 137 PSIG
ACTUAL:
LIQUID PRESSURE SHOULD BE +/- 10 PSI OF CHART
SUCTION PRESSURE SHOULD BE +/- 3 PSIG OF CHART
INTERCONNECTING LINES
GAS - 1-1/8” O.D.
LIQUID - 3/8”O.D.
