Servicing Hydrocarbon
Service Manual
1 Servicing Hydrocarbon
Overview
This cooler uses hydrocarbon (HC) R290 propane as its refrigerant. R290 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:
• Flammability
• Venting of R290 and compressor oil
• Asphyxiation
SKOPE does not recommend performing hazardous activities on the refrigeration system.
See “Refrigeration Cassette” on page 33 for more information including examples of
hazardous activities.

Service Manual
SKOPE TME650/1000N-3C
Service Mode Service mode can be accessed and used via the SCS Connect Field app (see “SCS Connect
Field App and Track App” on page 10), or the controller faceplate (see below).
Note: A 9 digit pin code is required to access service mode via the controller buttons. Contact
your User Manager to receive your activation code.
There are 5 main service mode categories when accessing and using service mode via the
controller faceplate:
Parameters
Provides access to and editing of individual controller parameters.
It is not recommended that parameters are changed unless absolutely necessary. If incorrect
parameter settings are suspected, reload the complete parameter set.
Reset
Returns the controller back to factory settings. Parameter set must be reloaded after
performing a reset.
Manual test
Allows inspection of input values from sensors, and check the effects of output adjustments to
peripherals, and to run preset test routines.
Statistics
Displays logged values and event counts to assist with fine tuning and diagnostics.
About
Lists the properties of the refrigeration system and the controller, including cooler model
codes, firmware, hardware and software versions.
SCS Connect Field App and Track App
Connecting Follow the procedures below to install and set up the app, and connect to a controller.
Note: The SCS Connect Field app and Track app are separate from the SKOPE-connect app.
Procedure 5: To enable and use service mode via the controller faceplate
1. Press and hold the up and down buttons simultaneously until prompted to enter the 9 digit pin
code.
2. Enter service mode pin code.
3. Use the up, down, back/abort and next/enter buttons to navigate to the desired category.

App
Categories
Various options are available in the app menu to provide information about the connected
controller and its cooler. Available menu option depend on the user’s access level.
Home screen
The home screen shows a graphic representation of the current state of the cooler being
controlled.
Procedure 6: To install the SCS Connect Field app
1. Download and install the Connect Field app or Track app from Google Play or Apple Store (search
for “scs wellington”).
2. When you first run the app, you will be requested to enter an activation code. Contact your Service
Manager or SKOPE to receive your activation code (you must be connected to the internet at the
time of activation).
3. Your activation code is unique to you, and determines your personal access level for the app.
NEVER share it with anyone else. The same code will give you access to all SCS apps you are
authorised to use.
4. Once activation is complete, you must define a 4-digit PIN code. This can be any code unique to
you. Each time you start the app, you will be required to enter this same PIN code. This is to
prevent other people accessing the app from unlocked phones.
5. You can see which databases you are activated for from the “Settings” screen. You can be activated
on more than one database at the same time. Simply select ACTIVATE ANOTHER DATABASE,
and enter the new database’s unique activation code, as in Step 2.
Procedure 7: To connect to a controller
1. Check that the Bluetooth logo on the top right of the controller faceplate is lit, indicating that the
controller is ready to connect to a device.
1. Note: A flashing Bluetooth logo indicates that the controller is currently connected to a device.
2. Open the SCS Connect Field app.
3. Select a controller to connect to from the list of visible controllers.
4. Note: This list is filtered by your activation permissions, so devices you are not authorised to
connect to will not be displayed.
5. Select “connect” to connect to the controller.
6. Check that the Bluetooth logo on the top right of the controller faceplate is flashing, indicating that
the controller is connected.

parameters are not applied until DISCONNECT has been selected from the menu (after
loading the new parameter set).
Load parameter file
Allows reloading of the default parameter set, or changing to a new parameter set. See
“Replacing the Controller” on page 35 for instructions. Note: Updated parameters are not
applied until DISCONNECT has been selected from the menu (after loading new parameter
set).
Statistics

and alarms.
SCS info
Controller version and cooler asset information.
SCS setup
Add or change SCS info (see above).
Disconnect
Disconnect from currently connected controller.
Settings
Change app general settings.
Faults and Alarms
The following tables explain 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 cabinet is connected to the power supply and has warm product, check the SCS Connect
Field app for an 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 fault and alarm descriptions and possible causes and actions. The
service tech type column refers to the service technician skill level required to complete a task.
Refer to the SKOPE HC Service Policy for service tech type details.

6 Replacement Procedures
Lighting
The cooler is fitted with LED modular interior and sign lights. Ensure the light is replaced with
the same light type. Fluorescent or LED tubes cannot be used in place of LED modular lights.
Refer to the table below for replacement light specifications.
The lighting is made up of three components which are replaceable:
• LED modular light
• Light power supply (1 per cabinet)
• Interior wiring loom (1 per door)
Power is supplied to the lights by the power supply (located in the cabinet electrics panel above
the door/s) via the wiring loom/s which run down the sidelight channel.
Lighting components are all non-serviceable items. If a component is faulty, it should be
removed and a SKOPE OEM new replacement component fitted.
Refer to the diagnostics table below to determine which component may be at fault, and the
procedures over the next few pages for component replacement instructions.
Ensure the cabinet is isolated from the power supply before cleaning or removing parts.
IMPORTANT
Replace the light with the same SKOPE OEM part.
DO NOT use alternative LED strip or tube lights, or fluorescent
tubes.

Doors
Alignment
Adjustment
If a door is out of alignment, realign it by loosening the top hinge bracket fixing screws, and
move the top of the door as required.
Height
Adjustment
A height adjustment block is fitted below the bottom hinge. As standard, the notched edges on
the bottom of the hinge and the top of the height adjustment block align to set the door to the
correct level. If the door is not at the correct height when at the standard setting, follow the
steps below to adjust the height.
Note: On three door models, the height of the middle door cannot be adjusted.
Replacing the
Gasket
The one-piece door gasket clips into the door frame and runs around the perimeter of the door.
Remove the gasket by peeling it from the door frame, starting at a corner.
If the gasket is out of shape after refitting, use a hair dryer to heat and reshape it.
Removing and
Refitting the
Door
For ease of servicing and to reverse the hinging, the door can be removed from the cabinet.
Refer to image below for door hinging components.
WARNING
For safe door operation the door bottom hinge bracket must
always be fitted with a split pin.
Procedure 12: To adjust the door height
1. Isolate the chiller from the power supply.
2. Loosen the bottom hinge and remove the height
adjustment block.
3. Set the door to the correct height, rotate and refit the height adjustment block to the most
appropriate setting and tighten up the bottom hinge screws.
