Servicing Hydrocarbon
Service Manual
1 Servicing Hydrocarbon
Overview
This cabinet uses hydrocarbon (HC) R290 as its refrigerant. R290 is a natural refrigerant that
has a very low environmental impact.
Special service requirements are needed, as R290 is a flammable refrigerant.
Safety hazards
The main hydrocarbon safety hazards are:
• Flammability
• Venting of hydrocarbon and compressor oil
• Asphyxiation
Service requirements
Do not interfere with the refrigeration system. All refrigeration maintenance and repairs must
be undertaken according to the SKOPE Hydrocarbon Service Requirements. See the “SKOPE
Hydrocarbon Service Requirements” below for more information, including examples of
hazardous activities.
Electrical safety precautions
To comply with safety and radio interference regulations, make sure you route wiring correctly
and use the correct components. In order to maintain safety and compliance with regulations,
any wiring that is disturbed during servicing must be replaced and secured in its original
position.

xMUST – Not modify or alter the design of SKOPE equipment in any way
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

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.
