6Servicing Hydrocarbon

Service Manual

SKOPE TMF-N ActiveCore Series

1Servicing Hydrocarbon

Overview

This ActiveCore freezer range utilises 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:

Flammable refrigerant.

Venting of hydrocarbon and compressor oil.

Asphyxiation.

Do not interfere with the refrigeration system. All refrigeration maintenance

and repairs must be undertaken according to the SKOPE HC Service

Requirements below.

See “SKOPE HC Service Requirements” on page 7 for more information

including examples of hazardous activities.

Electrical safety precautions

Correct wiring routing is as important as use of correct components for

compliance with safety and radio interference regulations. In order to

maintainsafety andcompliancewith regulations,any wiringthatis disturbed

during servicing must be replaced and secured in its original position.

SKOPE TMF-N ActiveCore Series

Servicing Hydrocarbon

Service Manual

SKOPE HC Service Requirements

Servicing must only be performed byApproved SKOPE Service Technicians, and must meet all

requirements in the SKOPE HC 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.

3Electronic Controller

Overview

The freezer is fitted with a Wellington Drive SCS Connect electronic

controller. The controller is located above the door/s and visible from the

outside of the freezer.

Controller servicing can be performed via the controller faceplate, or the

SCS Connect Field app.

This does not control the cabinet body and door heater elements

Apps

SCS Connect

Field App The SCS Connect Field app is designed for service techs, and provides

access to the controller from mobile devices with Bluetooth capability. The

app provides information on data logging, alarm notification and diagnostic

control.

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 SCS Connect Track app is used to upload data from freezers fitted with

a Wellington SCS Connect electronic controller.
