• Discharge temperatures should be between 140° F - 221° F during normal operation. If over 221° F, check for low refrigerant and verify liquid service valve isopen.• Compressor will stop if discharge temperature reaches 248° F. If below 140° F for long periods, the system is most likely overcharged.

** NOTE: Operation data must be obtained using SNET Pro 2 service software and MIM-C02N communication converter. **

Indoor Unit DataCooling trial operation

Average indoor SH (EVA_OUT - EVA_IN):

• Indoor EEV steps will range between 0 ~ 2,000. Under normal operation and conditions the indoor unit EEV(s) should stay within 250 ~1400 steps.

• If more than 50% of indoor unit EEV's SH ((EVA_OUT) - (EVA_IN)) > 11° F and EEV step of those units > 1400, the system maybeundercharged.• If a small percentage of indoor unit EEV steps are > 1400 under standard operating and space conditions, verify the distance from the first Y-

(EVA_OUT - EVA_IN) should equal approximately 0 ~ 7 after sufficient system operation times. This value will vary initially based on outdoor conditions and indoor conditions.

MAIN unit SUB1 unit SUB2 unit NOTES

• When IPM board temperatures ≥ 194° F the system will modify operation to prevent overheating. No errors will occur until temperatures reach 212° F.Capacity can decrease during protection without any visual indication of protection occurring if below 212° F.

NOTES

• Low pressure range during cooling test operation: 85 ~ 128 PSI. When outdoor temperatures and indoor loads are high, this value may be higher.• Low pressure range during heating test operation: 71 ~ 106 PSI. This is a basic reference as ambient temperatures will change this value.• High pressure range during cooling test operation: 355 ~ 469 PSI. This value can increase with ambient temperatures (max. 512 PSI)• High pressure range during heating test operation: 355 ~ 455 PSI. This value can decrease when outside ambient temperature is below 32° F or indoortemperature is below 68° F.

• Under normal operation and conditions, EVA_IN temperature should be between 45° F - 57° F for all indoor units• Under normal operation and conditions, EVA_OUT temperature should be between 45° F - 57° F for all indoor units

Samsung DVM S System Startup Checklist, Operation Log, and Operation Reference

Indoor Unit Data (continued)Heating trial operation

• Under normal operation and conditions, EVA_OUT temperature should be between 113° F - 194° F for all indoor units.• Under normal operation and conditions, EVA_IN temperature should be between 91° F - 122° F for all indoor units.• Under normal operation and conditions, diffuser temperatures should be 105°F or greater.• EEV position will vary based on indoor and outdoor conditions.

Average EVA_IN temperature:

• If only a small number of indoor unit EVA_IN and EVA_OUT temperatures are lower than normal under standard operating and spaceconditions, verify the distance from the first Y-joint to each unit is within Samsung pipe limitations.• If all indoor unit EVA_IN temperatures are lower than 91.4 ° F, outside ambient temperature is below 41° F, and high pressure is below 356PSI, the system maybe oversized or overcharged.
