All installations and services must be performed by qualified personnel.

Read the temperature at header assembly to calculate the superheat. Then read the suction pressure and then add the line loss of 2 lbs. for 25’ of tubing. Then convert pressure into temperature.

Next, subtract the converted suction temperature from the measured coil header temperature and the end result is the superheat.

EXAMPLE:

Measured Temp = 50oF

(Off header assembly at 10:00 or 2:00 position) See Figure I.

Measured Pressure = 71PSI + 2PSI = 73PSI which equates to a 43oF saturation temperature. (Measured from pressure port)

(Listed temperature for measured pressure according to R-22 temperature scale on manifold gauge or R-22 section of pressure temperature chart)

The difference equals the degrees superheat = 7oF

All 10 SEER models of Thermo Pride air conditioners should have a 3oF to 7oF superheat at an 85oF to 95oF outdoor temperature and a 70oF to 80oF indoor temperature. The superheat

temperature will not be accurate if the indoor temperature is not within the 70oF to 80oF range. Therefore, an indoor temperature within the above range must be achieved before an accurate superheat can be measured.

MEASURING TEMPERATURE DROP ACROSS THE “A” COIL:

The temperature drop across the coil should be around 15oF to 20oF difference between inlet and outlet air. This should be measured as close to the air handler as possible, to eliminate duct losses.

ELECTRICAL

All wiring must conform to the provisions of local codes or in the absence of local codes with the provisions of the National Electrical Code, ANSI/NFPA No. 70-Latest Edition and this instruction manual. Equivalent type wire must be used if any of the original wire supplied with the unit needs to be replaced A 10 amp time delayed fuse or circuit breaker is recommended.

NOTE: Condensing unit is not included in above amp rating.
