The Master Frost C/M-800 is an ice maker designed for commercial use, offering efficient ice production and a range of features for easy operation and maintenance. This manual provides comprehensive instructions for installation, operation, troubleshooting, and warranty information.

Function Description

The primary function of the Master Frost C/M-800 is to produce ice. The ice maker operates by freezing water in a controlled environment, forming ice pieces that are then harvested and stored in an integrated bin. The machine is designed for continuous operation, ensuring a steady supply of ice for various commercial needs.

Important Technical Specifications

The Master Frost C/M-800 model has the following key technical specifications:

Production Capacity: 24 hours / 80 kg
Height: 880 mm
Width: 710 mm
Depth: 580 mm
Compressor: 651 W
Voltage: V 220 - 240/1/50 Hz
Cooling Gas: R452A
Water Inlet: Ø 3/4-GAS
Water Outlet: Ø 24 mm
Bin Capacity: 35-40 kg
Net Weight: 59 kg
Gross Weight: 63 kg

The power supply connection for the ice maker must have its own fuse. For the C/M-800 model, a 10 Amps fuse is required. Other models, such as C/M-1200, C/M-1600, and C/M-2800, require a 16 Amps fuse.

The ambient working temperature for optimal performance should not exceed 32 Celsius or be beneath 10 Celsius. If the ice maker operates in a warm ambient temperature over 42 Celsius and starts and stops within a few seconds, there is a risk of destroying the compressor.

Usage Features

The Master Frost C/M-800 is designed for user-friendly operation with several features to ensure efficient ice production:

Installation: The ice maker should be placed on a stable surface, ensuring proper ventilation. A minimum distance of 25-30 cm from the air-duct grilles is recommended to allow free airflow. It should not be placed near heat sources. The unit comes with all necessary components for installation, including an inlet and outlet for water. The water drain should be lower than the outlet of the ice maker to ensure proper drainage. After connecting the power cord and water supply, the machine will start the cycle after approximately 2 minutes.

Adjustment Switches: The ice maker features adjustment switches located behind the front cover. These switches allow users to fine-tune the ice piece size and volume. A screwdriver can be used to turn the switch for increasing or decreasing the volume of ice in each piece.

Minimum weight for C models is 17 grams and maximum 32 grams.
Minimum weight for M models is 20 grams and maximum 28 grams.

Operation Indicators: The ice maker has indicators for its operational status. If the machine stops due to marginal adjustments, it will produce a large mass of ice. In such a case, the ice mass must be removed, and the water melted by pouring hot water on top of the ice maker. Adjustments should then be made gradually. The ice maker will stop working when it reaches the point where the user has selected a quantity of ice to be taken.

Safety Precautions:

Never pour water on the ice maker or the power cord to avoid electric shock.
Do not place the ice maker in a position that allows the drain to be higher than the outlet of the water.
Do not leave a child to reach the ice maker with the intent to play with it.
After installation, destroy any plastic bag to prevent suffocation hazards for children.
The power supply must be connected with an efficient earthing system to prevent electrical shock.

Maintenance Features

Regular maintenance is crucial for the longevity and optimal performance of the Master Frost C/M-800. The manual outlines several maintenance tips and troubleshooting steps:

Cleaning:

Condenser Cleaning: Once a month, the condenser should be cleaned. The front cover needs to be removed, and the condenser cleaned with UP and DOWN movements. Do not supply the ice maker with water from a tank that is exposed to the sun.
Water Storage, Distributor, and Sprayers Cleaning: To clean these components, first disconnect the power, then open the door. Pull up the white flags, which are behind the water storage. Take off the sliding conveyor. Place hands down of the distributor and lift it first. Rotate it 60° and pull it out gently. Disconnect the distributors pipe from the pumps pipe. Clean the ice maker. Clean the sprayers with a toothbrush or a mix of water and vinegar.
Descaling: For quick cleaning of the ice maker, a mixture of water and vinegar can be used. Connect a 1.2 m Ø1/2" pipe to the outlet of the distributor. The other side of the long pipe should be placed in the water storage. Start the ice maker, let it run for 10 minutes, and then stop it. After that, wash the water storage with water and dry it. Connect everything back to its first place. The machine can then function again.

Troubleshooting: The manual provides a detailed troubleshooting guide for common issues:

Ice maker doesn't work:
- Check the plug – if there is any power.
- Check for short circuit – check fuses.
- Check if the storage is full of ice. If so, remove ice to perform production.
Ice maker works but doesn't produce ice/or is melting in the storage:
- Check the sliding conveyor. It might have moved from its position, preventing ice to fall in the storage. Light the water storage (behind flags). Light the sliding conveyor or slightly up step of water storage.
- Check the drain. The water may come back to storage and melt the ice. If so, install the ice maker higher from the drain.
- Unscrew the back cover, on the left you will find a black pipe. Squeeze it so any obstacle will remove.
Produced ice is unformed/bad shaped:
- Clean the distributor and sprayers (refer to TIPS section).
- Check for possible rubbish in the filter of the electro valve or pump.
- Check the pump.
- Check the electro valve.
Ice maker is working for long hours without producing ice:
- Lift the front cover of the device and with the brush clean with UP and DOWN movements only the condenser (The component it is first to your disposal).
- Check the working temperature of the ice maker. If it is over 42 Celsius, reduce the ambient working temperature, or install the ice maker somewhere else.
- If nothing of the above changes the problem, call for assistance from authorized personnel because the ice maker has lost its refrigerant (FREON (R452A)) due to transportation, hit, or from long use.
