SKOPE TME-N ActiveCore

Servicing Hydrocarbon

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.

Service Manual

SKOPE TME-N ActiveCore

SKOPE HC Service Requirements

Servicing must only be performed by Approved SKOPE Service Technicians, and must meet all requirements in the

SKOPE HC Service Policy (available from SKOPE), including the following:

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.

Door Handles

Fitting Door

Handles

For transit purposes the door handles may be packed separately inside the cabinet. If the door

handles are packed separately, follow the steps below to fit them to the door/s.

Procedure 1: To fit a door handle

1. Remove the handle/s from inside the cabinet by carefully cutting the cable ties securing the

handle, and remove the packaging.

A metal spring clip is fitted inside the handle mounts

at each end of the handle.

2. Ensure that the spring clips point up.

3. Place BOTH handle mounts simultaneously

onto both door brackets.

4. Then push the handle down onto the brackets,

until the handle locks into place.

Troubleshooting

• If the handle does not lock into place, check that the spring clips are pointing up and try again.

• If only one end of the handle locks into place, unscrew the door handle (see over page), and refit

ensuring both of the handle mounts are located onto the brackets before pushing the handle down

and locking into place.

Removing

Door Handles

The door handles can be removed for transporting and moving the cabinet through doorways,

or for refitting.

Shelves

The cabinet is fitted with five layers of wire shelves which may be positioned at different heights

to suit various products.

Shelf Clips Each wire shelf is held in place with four shelf clips, which clip in the shelf support strips and

slide up and down to the required shelf position.

The support strips are numbered to help place the shelf clips. You can see the numbers in the

bottom left hand corner of the shelf clip.

Procedure 2: To remove a door handle

1. Open the door, and peel back the door gasket from behind the handle mounts on the inside of the

door frame.

2. Unscrew the handle mounts through the holes on the inside of the door frame (top and bottom

screws only), and remove the handle.

3. Remove the bracket/s from the handle mount

by pressing the bracket in and down until it

unclips from the handle mount.

4. Fit and screw the bracket/s back onto the door.

Ensure the catches are pointing up as

pictured.

5. Refit the door gasket by clipping it back into place on the inside of the door frame. If the gasket is

out of shape after refitting it, a hair drier can be used to heat and reshape it.
