Technical Specifications Summary

Key technical specifications including power, output, and dimensions.

The Lindr CWP 300 V Green Line is a professional flow-through cooler primarily designed for winemaking, though it can also be used for fermenting must. This versatile device not only cools but also features a water heater, allowing for manual switching between cooling and heating modes. Its robust design and specific functionalities cater to the needs of winemakers for chilling or fermenting wine. The unit is equipped with a drain valve for easy water drainage and a water gauge for monitoring the water level, enhancing user convenience and operational control. The cooling system utilizes R290 (propane) as an environmentally friendly refrigerant.

Usage Features:

The CWP 300 V Green Line is designed for ease of use and precise control over temperature.

Controls and Adjustment:
- Cooling/Heating Mode Switch: A three-position switch (0 = off, I = cooling, II = heating) allows users to select the desired operational mode. In cooling mode, it's recommended to set a lower temperature on the cooling thermostat (no. 3) than on the pump control thermostat (no. 4). Conversely, in heating mode, a higher temperature is recommended on the heating thermostat (no. 3) than on the pump control thermostat (no. 4).
- Low Water Level Indicator: A red warning light on the front of the device indicates low water level in the tank, automatically turning off the device for safety. The device restarts automatically once water is refilled.
- Dixell XR20CX Thermostat (no. 3): Used for setting the water temperature within the cooler.
- Dixell XR20CX Thermostat + External Sensor (no. 4): This thermostat regulates the pump and can measure the temperature of the cooled product. The circulation pump activates if the temperature deviates from the set value and switches off automatically once the target temperature is achieved within the specified range.
- Antifreeze Recommendation: If setting the thermostat (no. 3) within the -6 to 0°C range, the cooling circuit must be filled with an eco-friendly antifreeze mixture based on monopropylene glycol, suitable for all heating and cooling systems.
Installation and Placement:
- The cooler should be placed on a stable, level surface with a maximum permitted inclination of 2 degrees.
- Unobstructed air circulation is crucial for proper operation and maximum output. Minimum required distance of vents from an obstacle is 50 cm; in places without vents, 7 cm.
- The device must not be placed in an enclosed space, near heat sources, or exposed to direct sunlight.
- Ensure sufficient free space for air circulation, heat dissipation, and fresh air supply.
- The power socket must be easily accessible for immediate unplugging in case of emergency.
Filling the Tank and Interconnecting with Exchanger:
- Fill the plastic tank up to the MAX mark with clean water or antifreeze.
- Interconnect the appliance with the heat exchanger (not included) using speed fittings.
- After connecting the heat exchanger and starting the pump, check and top up the water level as it may drop.
- Do not tamper with or move the device while it contains water to prevent overflowing.
Putting into Operation:
- Fill the tank with clean water (or antifreeze).
- Connect the water inlet and outlet to the heat exchanger.
- Set the desired mode (cooling – heating) using the switch.
- Set the target water temperature and the target temperature for pump regulation.
- Check all connections for leaks. If a leak is found, turn off the device and fix it, or contact a service center if unsure.
Speed Fittings:
- Installation: Grasp the rapid coupling and insert the hose all the way (approx. 20 mm) into the speed fitting body. The hose end must be straight; moisten it if it doesn't go in easily.
- Removal: Hold the grey ring tight against the speed fitting body and pull out the hose. Do not pull the hose without holding the ring, as this can damage the hose. Hoses must not be pressurized during removal.

Maintenance Features:

Regular maintenance is essential for the device's longevity and optimal performance.

Inspection Before Every Use:
- Perform a visual check of the device.
- Check the lead-in cable for damage.
- Inspect the condenser for cleanliness; clean more frequently than once a month if excessively polluted.
- Check the water level in the tank.
- Do not use the device if any defects or malfunctions are found.
Periodic Checks:
- Daily: Check the water level in the tank.
- Weekly: Check the lead-in cable for damage and ensure the plug is firmly in the socket. Verify that the device is not exposed to radiant heat and that air circulation is not obstructed.
- Monthly: Check and regularly clean the cooling unit's condenser. Check water purity in the chiller tank; change if necessary.
- Annually: Have an engineering inspector check the electrical safety of the device.
Cleaning the Condenser:
- The condenser must be cleaned at least once a month by professional personnel, using compressed air or a brush.
- ALWAYS disconnect the appliance from the power supply before any intervention to prevent electrical injury.
General Maintenance:
- The condenser must be checked for cleanliness every month. Any dirt found must be cleaned with compressed air or wiped off to prevent reduced cooling output or damage to the cooler.
- Wipe the device only with a soft, lightly moistened cloth.
Troubleshooting (Table of Malfunctions):
- Device too noisy: Check for contact with foreign objects or sunken objects in the fan compartment. Remove obstructions.
- Device does not work: Check if the power cable is plugged in and undamaged. Ensure the main switch is on and the thermostat is correctly set.
- Device turned on but does not cool: Check for obstructed air vents and a dirty condenser. Clear obstructions and clean the condenser.
- Speed fittings issues: If the hose is poorly inserted, unplug it, check for sharp edges, and reinsert correctly. If scratches are on the hose, shorten it with a knife if necessary.
- If issues persist after these steps, contact a service center, providing details such as type of defect, product type, production year, and serial number.
Spare Parts: Always use original components. When ordering, provide the product type, production year, and serial number. The manufacturer is not responsible for non-original or non-recommended components.
Environmental Protection: The product must not be disposed of in communal waste. Electrical waste in the Czech Republic is handled via the Rema System (www.remasystem.cz). In other countries, waste sorting is subject to local regulations, promoting recycling and reuse to protect the environment.
