- Page 13 12. Examine the heater termination thermostat (HTT) for proper positioning/damage (Refer to Figure 11). Replace as necessary. Figure 11 Heater Termination Thermostat 13. Examine internal valves, solenoid coils, as required per unit model number checking for proper positioning, physical damage, leaks or corrosion.
- Page 14 Front of Unit Refer to the Warnings and Notes section in this manual before proceeding with these instructions. Remove All Exterior Panels 1. Examine unit for traces of oil residue. Leak check the unit, includ- ing the compressor, using an electronic leak detector. Leaks are typically found as a dirty/oily residue on compressor joints, high pressure switch connection, pressure transducers (if fitted), piping connections etc.
- Page 15 3. Ensure that the remote monitoring and interrogation sockets are secure and free from damage and corrosion and caps are properly tethered to the unit (Refer to Figure 13). Repair/replace as required. Figure 13 Interrogation Socket 4. Inspect the compressor and mounting plate for severe corrosion, and check compressor shock mount for damage (cracks).

It may be necessary to remove the condenser fan for complete access. Figure 17 Condensate Defrost Drain Tube Model/Serial Number plate Flexible condensate defrost drain tube 9.
- Page 19 11. Examine the water-cooled condenser (if equipped, refer to Figure 19): a. Periodic paint touch up of the water-cooled condenser may be required. b. Determine whether the water-cooled condenser is scaled. Refer to the operation & service manual for specific details on cleaning and maintenance of the water-cooled condenser.
- Page 20 12. Examine power cables: a. Check the cable to make sure it is securely attached to the unit and the clamp is in position. b. Replace or repair the cable if damaged or crushed in any man- ner. Replace the cable if more than one repair joint is found. c.
- Page 21 14. Remove left and right hand evaporator access panels. Ensure the evaporator motor mounting brackets or the evaporator motor stator brackets are properly torqued. Refer to the operation & service manual for specific torque values. Locating operation & service manuals is explained in the Purpose section.
- Page 22 OPERATIONAL INSPECTION Refer to Warnings and Notes on page 2 before proceeding. 1. Remove the Lock Out/Tag Out device and plug unit in to power supply. Check that voltage is good on all 3 phases. 2. Install the manifold gauge set using good system hygiene practices. For PrimeLINE units, operating pressures can be viewed by going to code 12 (Suction Pressure) and code 14 (Discharge Pressure).
- Page 23 5. Enter a DataCORDER Trip Start (Refer to Figure 23). Consult the instruction label on the face of the unit for correct procedure. Figure 23 DataCORDER Trip start 6. Check the discharge and suction pressures on manifold gauge set (or through codes), consult the operation &...
- Page 24 Figure 24 PTI Tests 10. Check the unit’s TXV and EEV superheat setting. Consult the operation & service manual for the correct superheat setting and procedure. Valve settings should not be adjusted if incorrect superheat is observed then the valve or sensors must be replaced. Note: For PrimeLINE units, the superheat can be observed at code 54.
