Equipment and Machinery Practice Cards

Vocabulary-style flashcards covering the verification, temperature requirements, maintenance, and storage rules for thermometers and deep freezers.

Thermometer Verification Procedure

Place the sensor needle in a cup filled with icy water and wait for the display to stabilize before use.

Standard Thermometer Accuracy Range

The thermometer is considered functional if the reading is $0 \text{ } ± \text{ } 1 \text{ } ^∘\text{C}$.

Decimal Thermometer Accuracy Range

If the sensor measures decimal values, the acceptable accuracy is $± 0.5 \text{ } ^∘\text{C}$.

Deep Freezer Operating Temperature

The required temperature range for freezer chambers, kitchen upright/wall/grill freezers, and potato dispensers is $-18 \text{ } \text{to} \text{ } -23 \text{ } ^∘\text{C}$.

Meat Freezer Cooldown Time

The required time for meat freezers to cool down to $-18 \text{ } ^∘\text{C}$ is $45 \text{ } \text{minutes}$.

Defrost Clock Minimum Time Points

The freezer chamber defrost clock must be set for a minimum of $4$ time points.

Defrost Clock Minimum Interval

At least $4 \text{ } \text{hours}$ must elapse between two scheduled defrost time points.

Recommended Defrost Cycles

The suggested time settings for the defrost clock are $6-12-18-24$ hours.

Deep Freezer Pallet Storage Height

Products must be stored on pallets at a distance of $15 \text{ } \text{cm}$ from the floor.

Freezer Wall Storage Clearance

Items must be kept at least $5 \text{ } \text{cm}$ away from the freezer wall.

Inter-Carton Storage Clearance

Products must be stored at least $2.5 \text{ } \text{cm}$ away from the cartons of other products.

Evaporator Storage Clearance

Items must be kept at least $30 \text{ } \text{cm}$ away from the evaporator in all directions.

Defrost Clock Resetting Conditions

The clock must be reset when switching to or from daylight saving time (summer/normal time) or after a power outage.
