Safety
Checking for Refrigerating Equipment

Checking for Electrical Devices

Ensure continuous ventilation throughout the work.
Safely disperse any released refrigerant during ventilation, preferably expelling
into the atmosphere outside.
When changing electrical components, must ensure they are suitable and meet
the correct specifications.
Must ensure to follow the guidelines provided by the manufacturer for
maintenance and service.
Must reach out to the manufacturer's technical support for help if there are any
unsure points.
When using flammable refrigerants during installation, please conduct below
checks:
1. Must ensure ventilation equipment and outlets are not obstructed and are
functioning properly.
2. Must check the secondary circuit for the presence of refrigerant if an indirect
cooling circuit is being used.
3. Must ensure the equipment markings are legible and visible and correct any
markings that are not legible.
4. Refrigeration pipes or components should not be exposed to corrosive
substances unless they are made of corrosion-resistant materials or are
properly protected.
Maintenance and repairs of electrical components should include initial safety
checks and component inspection procedures.
Initial safety checks should include but not limited to:
1. Safe discharge of capacitors to prevent sparking.
2. No live electrical components or wiring exposed during system charging,
recovery, or purging.
3. Continuity of earth bonding.
Must follow the guidelines provided by the manufacturer for maintenance and
service.
Must reach out to the manufacturer's technical support for help if there are any
unsure points.
If a fault that could compromise safety is present, do not connect the electrical
supply to the circuit until it is satisfactorily resolved.
If the fault cannot be immediately corrected but operation must continue,
implement a suitable temporary fix.
The equipment owner must be informed of any issues so that all parties are
aware.
Repairs to Sealed Components
Must disconnect all electrical supplies from the equipment before removing any
sealed covers during repairs.
