SKOPE Reflex 1-Door Underbench Fridge and Freezer
Servicing Hydrocarbon
Service Manual
1 Servicing Hydrocarbon
Overview
This appliance uses hydrocarbon (HC) as its refrigerant (Fridge: R600a, Freezer: R290).
Hydrocarbon refrigerants have a very low environmental impact.
Special service requirements are needed, as hydrocarbon refrigerants are flammable.
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.

6Servicing Hydrocarbon
Service Manual
SKOPE Reflex 1-Door Underbench Fridge and Freezer
SKOPE HC Service Requirements
Servicing must only be performed by Approved SKOPE Service Technicians, and must meet all requirements in the
SKOPE Hydrocarbon Service Policy (available from SKOPE), including the following:
Hydrocarbon work – SKOPE Service Policy
It is the responsibility of the service technician to follow SKOPE’s Hydrocarbon equipment service policy
and by accepting a service work order they agree to the following (where applicable):
xMUST – Ensure all workers are trained in the SAFETY of hydrocarbon products to the appropriate
level for the work required.
xMUST – Follow all Local Safety Regulations relevant to flammable refrigerant gases.
oAustralia should reference - AIRAH Flammable Refrigerants – Safety Guide
oNew Zealand should reference – Flammable Refrigerant Safety Documentation
(Refrigerant License NZ)
xMUST – Adhere to all on-site (workplace) Health and Safety requirements
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
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.

Service Manual
SKOPE Reflex 1-Door Underbench Fridge and Freezer
4 Electronic Controller
Overview
The cabinet is fitted with a Wellington Drive SCS Connect electronic controller. The controller
is located above the door and is visible from the outside of the cabinet.
Apps
SCS Connect
Field App
The Wellington Drive Field app for mobile devices allows technicians to connect and interact
with SKOPE equipment that utilise the Wellington Drive SCS Connect electronic controller.
The app allows technicians to:
• View the current state of cabinet components (temperatures, compressor and fan motor
states).
• View a 7-day history of those states.
• Manually change component states.
• Update and change controller parameters.
• Update controller firmware.
All technicians who service SKOPE equipment fitted with the Wellington Drive SCS Connect
electronic controller are required to have the Wellington Drive Field app installed on their
Bluetooth enabled mobile device. SKOPE also recommend that all technicians have the
Wellington Drive Track app installed.
See “SCS Connect Field App and Track App” on page 12 for information on setting up and
using the app.
SCS Connect
Track App
The Wellington Drive Track app for mobile devices transfers data from SKOPE equipment that
utilise the SCS Connect controller to a cloud based server.
The app works automatically in the background. When the app detects a controller, it connects
via Bluetooth to receive data from the controller and send data to the cloud. If no mobile data
connection is available, the app stores data until a connection becomes available.
SKOPE recommend that all technicians who service SKOPE equipment fitted with the
Wellington Drive SCS Connect electronic controller have the Wellington Drive Track app
installed on their Bluetooth enabled mobile device.
SKOPE
Connect App
The SKOPE-connect app is designed for end-users only, and provides wireless access to the
controller from mobile devices with Bluetooth capability.
The app allows end users to adjust some electronic controller settings including energy saving
modes, open/close hours and preset temperature set points for specific product.

Service Manual
Faults and Alarms
If a fault occurs, it is logged, the Fault - Alarm indicator is lit on the controller faceplate, and a
message may be displayed. Faults do not affect product temperature, and do not require
action from the shop owner, unless they turn into an alarm.
If an alarm occurs, it is logged, the Fault - Alarm indicator is lit, 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. Faults and alarms can be cleared by the shop owner by power-cycling
the cabinet. However the fault or alarm will only clear if the problem has been fixed. If the
problem still exists after a power-cycle, a service technician will need to fix the problem.
If the cabinet 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 cabinet 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 (available from SKOPE) for service tech type details.
