x MUST – Follow all best practice work activities for servicing hydrocarbon refrigerants (SKOPE

recommend attending specific hydrocarbon refrigeration handling training courses). Nitrogen must be used for purging system before commencing “Hot Work” – brazing.

x MUST – Adhere to relevant SKOPE Service Manual. If any contradiction, the local Regulations take

precedence over SKOPE requirements

x MUST – Work only in suitable, safe and compliant work spaces. Personal Protective Equipment

must always be used when working on Hydrocarbon equipment.

x MUST – Service people diagnosing refrigeration faults must always carry and utilise Flammable

Gas detectors when working on Hydrocarbon equipment.

x MUST – Prior to any service work; know where and how to safely and quickly isolate power supply

to cabinet

x MUST – Not perform any Hot Work (brazing etc.) in the field. These are to be completed in a

SKOPE approved hydrocarbon workshop (in a dedicated specific Hazardous Work Area for Hot Work)

x MUST – Not transport a refrigeration system with an active leak. If there is an active leak the

refrigerant must be safely removed (with use of Bullet Piercing Valve or Line Tap valves) before transporting. Valves must be removed at the hydrocarbon service depot once repair is completed.

x MUST – All hydrocarbon workshop areas must have emergency plans; that includes suitable

evacuation and fire control plans and equipment.

x MUST – Only use refrigerant grade hydrocarbon, to precise mass specified on removable

refrigeration system serial label.

x MUST – Be accurate refrigerant charge; The refrigerant mass is ultra-low charge and must only be

measured in by accurate scales to +/- 1.0gram. Refrigerant MUST not be overcharged; or added to an already charged system.

x MUST – Use identical drier replacement; as any change will affect gas charge volume; and effect

reliability compliance and safety.

x MUST – Any pipework replacement, must be identical to OEM parts. x MUST – Not introduce a sparking device inside a cabinet or inside a removable refrigeration

system. Battery drills should not be used.

x MUST – Not perform any activity that could stress a refrigeration pipe (unless in a workshop) x MUST – Have the Wellington Drive SCS Field app installed on a Bluetooth enabled device carried

by the service technician. The app should be utilised for safe, accurate diagnosis of the system and it is required to complete a controller replacement in the field.

x RECOMMENDED – Have the Wellington Drive SCS Track app installed on a Bluetooth enabled

device carried by the service technician. This passive app collects system data from the Wellington Drive SCS Connect Controller and transmit it to the cloud.

Service Manual

Faults and Alarms

The following table explains faults and alarms that the electronic controller may log and display.

If a fault occurs, the fault - alarm indicator is lit on the controller faceplate, but no message is displayed. Faults do not affect product temperature, and require no action from the shop owner.

Alarms are logged and the alarm message is displayed on the controller faceplate. Alarms may result in abnormal product temperature.

Some faults and alarms can be cleared by the shop owner, and others can only be cleared by a service technician.

If the cooler is connected to the power supply and has warm product, check the SCS Connect Field App for active fault or alarm, and investigate. If the cooler does not have an active fault or alarm, check the app statistics to determine if and when the controller signalled a fault or alarm.

Refer to the tables below for faults and alarm descriptions and possible causes and actions. The service tech type column refers to the service tech skill level required to complete a task. Refer to the SKOPE HC Service Policy for service tech type details.

instructions available on the instruction sheet attached to the back of the sign panel, or on page 41 of this service manual.

Diagnostics The following diagnostic test is useful for workshop diagnosis of a short of

gas situation. Perform the test before opening the refrigeration system.

It is beneficial to have a correctly operating unit running beside the unit being serviced to compare behaviour.

Note: These diagnostic procedures are indicative only.

Refrigeration system diagnostic test (perform in suitable workshop)

1. Isolate the chiller from the power supply and remove the refrigeration unit, and remove the unit cover.

2. Place unit on bench and connect service probe to red plug on unit.

3. Connect the refrigeration unit to the power supply and allow to run for approximately 10 minutes until the evaporator temperature stabilises.

4. Refer to the table below to determine if the system charge is correct. A system with the correct refrigerant charge will frost back towards the compressor. The point where the frost stops is affected by the ambient temperature. The table below details the frost stop point on a correctly charged system running on the bench.

5. If the suction pipe frosts to the appropriate frost stop point, the charge is likely correct. If the frost does not go back to the point shown there may be a capillary blockage or compressor fault.

6. Use the table below to determine whether the system is short of refrigerant or a blocked capillary.

7. After fault has been diagnosed and repaired, reassemble the refrigeration system and test run.
