Frequently Asked Questions - EWAT350B-SLA2-VFDFAN DAIKIN
How do I start the Daikin EWAT350B chiller?
To start the chiller, ensure the power supply is connected and the main switch is turned on. Navigate to the controller menu and select 'Start', then confirm. The unit will automatically perform a pre-start check and begin operation. Refer to the manual for detailed operational steps.
What type of refrigerant does this unit use?
This chiller uses R410A refrigerant. R410A is a HFC blend that is ozone-friendly and widely used in modern HVAC systems.
How often should I perform maintenance?
Regular maintenance is recommended every 6 to 12 months. Key tasks include cleaning the condenser coils, checking refrigerant pressure, and inspecting the water filter and electrical connections. Annual maintenance by a certified technician is advised.
What are the electrical requirements?
The chiller requires a 400V, three-phase, 50Hz power supply. It has a maximum power consumption of around 100 kW (check nameplate). A dedicated electrical circuit with appropriate circuit breaker is necessary.
How noisy is the unit?
The sound pressure level is approximately 75 dB(A) at 1 meter. At a distance of 10 meters, this drops to about 55 dB(A). The VFD-driven fans help reduce noise during partial load operation.
Can I install it indoors?
This model is designed for outdoor installation. It must be placed in an area with adequate airflow and clearance for condenser coils. Indoor installation would require ducting for exhaust and is not recommended.
What should I do if an error code appears on the display?
Refer to the error code table in the manual. Common issues include high pressure, low pressure, or fan failure. Reset the unit by turning off the main switch for 5 minutes. If the error persists, contact a certified Daikin service professional.
What is the recommended water flow rate?
The nominal water flow rate is 60 m³/h. The flow rate should be adjusted according to the cooling capacity and temperature difference. Proper flow is essential to prevent evaporator freezing.
How do I clean the condenser coils?
Clean the coils at least once a year. Use a soft brush or low-pressure water to remove dirt and debris. Avoid bending the fins. For stubborn dirt, use a coil cleaner solution and rinse thoroughly.
Is a permit required for installation?
Installation may require a local permit depending on regulations. Always check with local authorities. The unit must be installed by licensed HVAC technicians to ensure compliance with electrical and safety codes.
