Refrigeration installation South Africa
Freezer installation involves removing packaging, connecting the freezer to power, and allowing it to settle before adding food.
Steps
Remove packaging: Take off all packaging before starting installation.
Connect to power: Ensure the freezer is connected to a grounded 120 volt circuit with a 3-prong grounding outlet.
Let it settle: After installation, allow the freezer to sit for at least 24 hours before plugging it in. This allows the fluid inside the freezer to settle after being shaken during transport.
Add food: Once the freezer has stabilized, you can add food.
Additional considerations
The freezer should be on a dedicated circuit.
The ideal setting for a freezer is -18°C.
Frozen foods stored at 0°F (-18°C) or below can be kept indefinitely.
Chiller installation includes foundation, electrical, piping, and other work.
Foundation
Meet foundation requirements
Ensure a solid, level surface
Anchor the unit
Use safety chains, clevis connectors, and a lifting beam
Electrical
Install circuit breakers, if needed
Connect the unit to the terminal block
Use wiring sizes per NEC
Ground the unit
Install power load and grounding parts according to construction regulations
Piping
Install properly sized pipes
Connect the pipes securely
Use metal or reinforced hose connections
Install a fluid strainer
Install taps for thermometers and gauges
Install isolation and balancing valves
Install vents and drains
Install pressure relief valves
Install backflow prevention valves
Other work
Ensure the unit is positioned for proper airflow and heat transfer
Equip the unit with vibration isolators
Reserve ventilation space around the unit
Design and install freezing and cooling water systems
Equip the chilled and cooling water circuit with Y-type filters
Cover the chilled water piping system with insulation
Refrigeration repair can involve fixing issues with the components of a refrigeration system, such as the compressor, condenser, evaporator, and expansion valve.
Common refrigeration problems leaking, being too warm, and broken water dispenser.
Refrigeration repair tips
Check the condenser and evaporator fans
Check the door seal
Clean the interior and exterior
Inspect refrigerant levels
Clean condenser coils
Clean drain lines
Test defrost cycle
Monitor temperature settings
Refrigeration system components
Compressor: Moves the refrigerant through a system of valves and chambers
Condenser: Part of the refrigeration cycle that condenses the refrigerant
Expansion valve: Also called a throttle valve or meteric device, this part of the refrigeration cycle expands the refrigerant
Evaporator: Part of the refrigeration cycle that evaporates the refrigerant
Refrigeration cycle
The refrigeration cycle absorbs heat from indoor air and dispels it outdoors. The cycle consists of four main processes: compression, condensation, expansion, and evaporation.
