Service Manual
1 Servicing Hydrocarbon
Overview
This cooler uses hydrocarbon (HC) R290 propane as its refrigerant. Hydrocarbon is a natural
refrigerant that has a very low environmental impact.
Special service requirements are needed as hydrocarbon is a flammable refrigerant.
Safety hazards
The main hydrocarbon safety hazards are:
• Flammable refrigerant.
• Venting of hydrocarbon and compressor oil.
• Asphyxiation.
SKOPE does not recommend performing hazardous activities on the refrigeration system.
See “Refrigeration Cartridge” on page 38 for more information including examples of
hazardous activities.

xMUST – In cases where the refrigeration system is not readily removable from the cabinet; then the
entire cabinet MUST be sent to the Hydrocarbon workshop for repair.
xMUST – ONLY use SKOPE OEM Spare Parts; or identical replacement parts. Any variation in
replacement part may render the system non-compliant and unsafe.
xMUST – 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.
xMUST – Adhere to relevant SKOPE Service Manual. If any contradiction, the local Regulations take
precedence over SKOPE requirements
xMUST – Work only in suitable, safe and compliant work spaces. Personal Protective Equipment
must always be used when working on Hydrocarbon equipment.
xMUST – Service people diagnosing refrigeration faults must always carry and utilise Flammable Gas
detectors when working on Hydrocarbon equipment.
xMUST – Prior to any service work; know where and how to safely and quickly isolate power supply
to cabinet
xMUST – Not perform any Hot Work (brazing etc.) in the field. These are to be completed in a suitable
service depot / workshop (in a dedicated specific Hazardous Work Area compliant to local
flammable gas regulations)
xMUST – Not transport a refrigeration system with a known 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.
xMUST – All hydrocarbon workshop areas must have emergency plans; that includes suitable
evacuation and fire control plans and equipment.
xMUST – Only use refrigerant grade hydrocarbon, to precise mass specified on removable
refrigeration system serial label.
xMUST – 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.
xMUST – Use identical drier replacement; as any change will affect gas charge volume; and effect
reliability compliance and safety.
xMUST – Any pipework replacement, must be identical to genuine SKOPE parts.
xMUST – Not introduce a sparking device inside a cabinet or inside a removable refrigeration system.
Battery drills should not be used.
xMUST – Not perform any activity that could stress a refrigeration pipe (unless in a workshop).
xMUST – Get customer authorisation to permanently swap a removable refrigeration system.
xMUST – Have the Wellington Drive SCS Field app installed on a Bluetooth enabled device carried by
the service technician (exception is for cabinets that do not utilise the Wellington Drive Controller).
The app should be utilised for safe, accurate diagnosis of the system and it is required to complete
a controller replacement in the field.
xRECOMMENDED – 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.
xLogistics companies may be used to transport a complete refrigerator where no separation of the
refrigeration system occurs. Logistics companies are not required to be contracted to this SKOPE
Service Policy.

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.
SCS info Displays information about the cabinet and the
controller version.
SCS setup Allows you to add or change SCS info (see above).
Disconnect Allows you to disconnect from the currently
connected controller.
Settings
Allows you to change the app's general settings and
see which databases you have activated. You can
have more than one database activated at the same
time.
To add a new database, select ACTIVATE
ANOTHER DATABASE, and enter the new
database's unique activation code.
