• Ensure all compressor control circuits and contactors are functioning and compressors are running satisfactory. Visually inspect to ensure all compressor fixings are in place and secure in line with the Copeland maintenance documentation.

• Are all compressors operational and compressor feet are secure? Please report any defects found stating which system / pack and take photos where required.

  Yes

  No

  N/A

• Using a spanner (Torque if available) to check the tightness of the Rota Lock service valve connection on to the compressor body. Use manufacturers settings if Torque spanner is being used.

• Are all Rota Lock service valve connection tight and no visible corrosion to valve connection? Please report any defects found stating which system / pack and take photos where required. Correct any faults if possible and make SME / Ops aware of any serious concerns.

  Yes

  No

  N/A

• Using an Amp meter, check heater is operational when compressor is NOT running.

• Are all the Crank Case heaters operational where fitted? Please report any defects and change heaters where required.

  Yes

  No

  N/A

• Take oil sample (one shot test). SOP required which should cover the next step if the oil is out of spec. It should also cover the disposal of the old oil. Add to SOP that, if there are no sample points, these should be fitted when taking the oil sample. SOP required

• After carrying out oil test was there any defects found i.e. discolouration, acid traces or wax particles? Photos must be taken of oil test and colour

  No

  Yes

  N/A

• Check refrigerant levels are sufficient for correct operation. Ensure oil level is correct in all compressors and oil reservoir.

• Are the refrigerant levels above 10%? If the levels are below this amount please confirm with SME / Ops prior to adding any refrigerant to the system and report findings. Photos must be taken of all gas levels (sight-glass or level indicator)

  Yes

  No

  N/A

• Are the Oil levels correct? If the levels are below this amount please confirm with SME / Ops prior to adding any oil to the system and report findings. Photos must be taken of all gas levels (sight-glass or level indicator)

  Yes

  No

  N/A

• Using a differential or calibrated gauge, check the pressure differential between the suction and reservoir, for coalescent separators check pressure drop across internal filter

• When checking pressure differential did you find any issues which would cause oil return problems? Please report issues found and identify the system / pack.

  No

  Yes

  N/A

• Check and test HP, LP and oil control switches, trip main plant controller and let plant run in back up.

• When checking H.P switches please ensure we have them set below PRV activation point (normally 24.4bar). On the L.P. it would be recommended to stop the system at 0.3bar and oil switches should activate on low oil. Did any of the above prove to be faulty? Please report the issues found and take photos where required. *Ensure the packs are not left in backup*

  No

  Yes

  N/A

• Using a calibrated gauge, check suction and discharge pressure transducers are reading correctly, Calibrate or replace as required.

• Once the transducers have been checked and calibrated did any fail which need replacement?

  No

  Yes

  N/A

• Check all plant set points and parameters against commissioning data and/ or manufacturers settings. ( R404a, R448a, R407a system the discharge is required to be set at 11bar), ( R404a and R448a HT Suction should be set at 3.4bar and LT set at 0.8bar), (R407a HT suction should be set at 2.7bar)

• After checking all of the set points on the systems did you find any issues? Please report any findings and add photos where required

  No

  Yes

  N/A

• Check for pressure drop across suction filter.

• If we find there is a pressure drop on the suction filter please remove the filter using SOP. Was there any suction filters found in any of the systems?

  No

  Yes

  No

  Yes

  N/A

• Visually inspect all pressure vessels (Receiver) in line with PSSR regulations, Ensure vessels are in satisfactory condition with no corrosion.
