Replacement Procedures
Service Manual
SKOPE Reflex Upright Fridge, Freezer, Combo
Dedicated hydrocarbon gauges.
Intrinsically safe hydrocarbon combustible gas leak detector.
Intrinsically safe scales to 1gm accuracy.
Well ventilated work area.
Gas Detector A gas detector is required and must be used when servicing HC cartridges.
A gas detector is a safety device for Hydrocarbon gas to warn the technician
that hazardous flammable gas is present.
Leak Detector A leak detector is recommended for servicing HC cartridges. It is used to
track and locate the source of Hydrocarbon gas leaks.
On-Site Work The service technician must have required knowledge, skills and tools to
proceed with on-site refrigeration sealed system diagnostics.
Minimum knowledge and skills
Experience and qualifications suitable for work on a flammable
refrigeration system.
Performs no unsafe activity.
Fully complies with SKOPE HC service policy.
Minimum tools and equipment
Hydrocarbon gas detector
Safety signage - suitable to create a safe work zone 1.5m around the
cabinet.
Refrigeration gauge set - suitable for R290 flammable refrigerant.
Service vehicle
Suitable for transporting flammable gas (being HC refrigeration
systems). Vehicle storage area must be well ventilated externally,
and not ventilated into the vehicle. There must be no ignition sources
in the storage area, nor any areas where the gas may pool.
Must be able to transport cartridges.
Should carry minimum SKOPE HC service parts.
Not Cooling
Fault
If a customer reports a ‘not cooling’ fault, and it has been established that
the cabinet is not cooling, follow the procedure on page 40 when making the
service visit.
Hydrocarbon
Workshop
The following tools and equipment are required in the hydrocarbon
workshop:
Hydrocarbon leak detector.
Dedicated hazardous workshop area - suitable for servicing and
release of flammable refrigerant.
Refrigeration gauge set - suitable for R290 flammable refrigerant.
Dry nitrogen - suitable for purging and high pressure testing.
Refrigeration vacuum pump rated as suitable for use with R290 (by
vacuum pump supplier).
Charging scales rated as suitable for use with R290 (by scales
supplier), accuracy to 1.0gm.
R290 refrigerant supply cylinder.
Raising the
Front Panel
When working on the cabinet top/cartridge area with the front panel swung/
rotated up, the front panel must be restrained so that it does not accidentally
fall. The front panel can also be unscrewed and removed during servicing.
