Evaporator Fan High
Activated
2.7 A 2.6 A 2.7 A
Condenser fan and compressor are
turned off. With evaporator fan on high
speed, Amp draw is measured and
compared to voltage and frequency:
• CSR40:
2.2 Amps approx. at 50 Hz,
2.6 Amps approx. at 60 Hz
• CSR20SL and CSR40SL:
2.7 Amps approx. at 50 Hz,
3.2 Amps approx. at 60 Hz
Evaporator fan high speed amperes are
recorded in PTI log.

Probe Test
Activated
2.7 A 2.6 A 2.7 A
Evaporator fans operate on high speed
for 3 minutes. Then probe test runs until
temperature difference between sensors
stops increasing. Maximum temperature
difference allowed:
• Return/Evaporator: 1.5 C (2.7 F);
return air sensor temperature must be
0.5 C (1.0 F) above evaporator sensor
temperature
• Return/Supply: 0.8 C (1.4 F); return air
sensor temperature must be 0.5 C (1.0
F) above supply air temperature
• LH Supply/RH Supply (if equipped): 0.5
C (0.9 F)

Reverse Phase
Activated
0.8 A 0.7 A 0.8 A
Condenser fan stops. Reverse phase
selector relay is energized and condenser
motor is started in reverse for 2 seconds.
Amp draw difference between correct and
wrong motor rotation must be less than
0.2 amps.

Compressor Test
Activated
7.1 A 7.0 A 7.1 A
With condenser fan on and compressor
on, compressor is operated at 25%
capacity. Amp draw is measured and
compared to voltage. Evaporator
temperature and condenser coil
temperature are measured and recorded
with condenser fan amperes in PTI log.

Injection Valve Test
Activated
7.6 A 7.5 A 7.6 A
Condenser fan and compressor remain
on. Liquid injection valve is turned on.
Amp draw is measured and verified to be
a minimum of 0.2 amps higher that test
P1.09.
