Replacement Procedures
Service Manual
SKOPE OD1100N
Refrigerant identification
Correctly identifying the refrigerant is critical to maintain safety and the correct functioning of
the cabinet.
The cabinet rating label (located in the upper inside of the cabinet) states the refrigerant
type.
Warning labels are fitted to hydrocarbon refrigeration coolers to indicate the use of
hydrocarbon refrigerant.
Personal protective equipment (PPE)
Correctly wear or use all PPE required by local regulations and procedures during servicing.
Service equipment
Only use dedicated hydrocarbon service equipment which is hydrocarbon-compliant.
Electrical equipment that could be exposed to the refrigerant must be intrinsically safe.
In addition to standard tools for accessing and removing parts, specialist tools are required for
completing the refrigeration system service tasks in this manual:
Intrinsically safe refrigeration vacuum pump, rated by the manufacturer as suitable for use
with hydrocarbon refrigerant
Dedicated hydrocarbon gauge set
Flammable gas detector to warn if flammable refrigerant is present
Charging scales, rated by the manufacturer as suitable for use with hydrocarbon
refrigerant, accurate to 1 gram
Leak detector
A leak detector is used to track and locate the source of hydrocarbon gas leaks. It is:
recommended for servicing hydrocarbon units on-site.
required for servicing hydrocarbon units off-site.
Service vehicle
Must be suitable for transporting flammable gas.
Vehicle cargo area:
▪ Must be well ventilated to outside the vehicle only.
▪ Must have no ignition sources, nor any areas where the gas may pool.
Must be able to transport swap units.
Should carry minimum SKOPE hydrocarbon service parts.
On-site Work
The service technician must have required knowledge, skills, qualifications, and tools before
beginning any on
-
site work on the refrigeration sealed system.
Minimum knowledge and skills
Qualifications and certifications required by local/state regulatory bodies to service
hydrocarbon refrigeration systems
Safe working practices, including a safe working environment at all times
Minimum tools and equipment
Safety signage and/or barrier – suitable to create a safe work zone 1.5 m around the
cabinet
Hydrocarbon gas detector
Dedicated hydrocarbon gauge set
Bullet valves/line piercing valves suitable for a 6 mm tube

site Work
Hydrocarbon workshop
The following tools and equipment are required in the hydrocarbon workshop:
Dedicated area for hazardous work – suitable for servicing and releasing flammable
hydrocarbon refrigerant
