Installation Requirements for Direct-Cooling Block Ice Machines
Buying a direct-cooling block ice machine is just the first step. Every detail in the installation process directly affects the equipment’s lifespan, ice-making efficiency, and electricity costs. Today’s guide will help you turn the manufacturer’s installation requirements into an easy-to-understand checklist.
1. Core Operating Parameters of the Equipment
（1）. Suitable Refrigerants
Supports R22 / R404A / R507A
Note: The specific refrigerant for each model should follow the plate on the equipment. Do not replace the refrigerant arbitrarily to avoid system high-pressure faults or compressor burnout.
（2） Operating Environment Temperature
Suitable ambient temperature: 5℃～40℃
The equipment should be placed indoors with ventilation. Long-term exposure to high-temperature, closed environments can directly reduce ice production, increase energy consumption, and trigger frequent safety shutdowns.
（3） Compatible Power Supply Voltage
220V / 60Hz / 3P
380V / 50Hz / 3P
415V / 50Hz / 3P
440V / 60Hz / 3P
Note: The actual power standard should follow the equipment nameplate. Incorrect voltage may cause electrical control failures or the compressor not to start.
2. Site and Placement Requirements
Indoor placement, with a factory ceiling height of no less than 4 meters.
It is recommended to have a passage of more than 1.2 meters around the equipment, and leave at least 250mm at the back for heat dissipation. If the ambient temperature exceeds 35°C, it is suggested to install an exhaust fan for forced ventilation.
3. Electrical Installation
Independent Power Supply: A dedicated distribution cabinet must be installed from the transformer to the machine, equipped with a leakage protection switch inside.
Cable Selection: Use copper-core cables. Do not simply estimate by “total power ÷ 2.” The correct method is to calculate according to the equipment’s rated current and cable length (increase the cross-section if over 30 meters) to ensure voltage fluctuations do not exceed ±10%.
Grounding must be reliable, and fuses and leakage protection should be provided.
4. Water System (Key Factor Affecting Ice-Making Efficiency)
Ice-Making Water Tank: The volume should be no less than 0.8 times the daily production, and the bottom of the tank should not be higher than 1.2 meters from the machine placement floor.
Inlet and Return Pipes: The water inlet for de-icing must be 2 cm higher than the water outlet (measured horizontally).
For machines using hot-fluoride de-icing, the body must be placed strictly level, otherwise it may cause de-icing malfunctions.
Water Quality Treatment: Tap water is preferred. If using groundwater or deep well water, a water softener must be installed, otherwise scale will significantly increase energy consumption (1mm of scale increases energy consumption by 6%~8%), and in severe cases, it may damage the evaporator. Regularly clean the condenser and water supply pipes with food-grade citric acid (1%~2% concentration).
5. Installation Notes
Water Collection: Within 0.5~1 meter around the machine, build a low brick wall about 10 cm high to collect the cold water discharged during de-icing for recycling, saving both water and energy.
Good Ventilation: Do not store items near the condenser. Regularly clean dust with a vacuum or small brush to prevent poor heat dissipation.
Compressor Protection: If the machine stops due to water shortage, excessive ice, or power failure, wait at least 5 minutes between restarts to avoid damage from frequent stopping and starting.
6. Delivery Acceptance Checklist
After receiving the equipment, check each item:
- Appearance intact, no transport damage
- All accessories complete, no damage
- Machine screws tightened, no loosening
- Electrical components intact, connections secure
- Voltage and refrigerant on the nameplate match the actual values
