e:: The following procedures are for initial settings. Sometimes conditions such as high or low ambient

temperatures may require that the settings be fine-tuned for optimum performance.

0 units are equipped with a compressor pressure regulator (CPR) valve located in the accumulator module

mounted on the back of the evaporator (See illustration below). It is used to limit the suction pressure during heat.

1. Install a gauge manifold set on the suction service port located on the upper suction tube in the evaporator to

monitor suction pressure going to the CPR valve (See illustration below).

2. Attach an additional compound gauge to the accumulator suction service port to monitor suction pressure after the

CPR valve (See illustration below).

3. Place a jumper wire between the 12 and CHB wires at the defrost termination switch to verify the unit will run in

defrost.

4. Start the unit and run it in defrost on the roadside compressor until the pressure on the gauge manifold set attached

to the suction service port in the evaporator stabilizes at a pressure above 45 psig (310 kPa).

5. Check the suction pressure on the compound gauge at the accumulator suction service port. It should be 24 ± 2 psig

(165 ± 14 kPa). If the setting is incorrect, remove the protective cap and adjust the compressor pressure regulator
valve to the correct setting.

6. Remove the gauge manifold set and the additional compound gauge when finished with the test.
