Daikin Air Conditioner RWEQ264TAYCU

The plate-type heat exchanger has a structure that does not permit dismantling and cleaning, or replacing any parts. Please pay attention carefully to the quality of water to be used for the plate-type heat exchanger in order to prevent corrosion and sticking of scale

The water to be used for the plate-type heat exchanger should have at least the quality as specified in the table of "4.4.1 Water quality requirements" on page 15

When using any corrosion prevention agent, scale depressant agent, etc., such agent should have no corrosive features against stainless steel and copper

2 Management of condenser water flow rate

If the condenser water flow rate is not enough, it will result in freezing damage to the plate-type heat exchanger. Check for any clogging of the strainer, any air being caught, any reduction in the flow rate due to failure of the circulation pump by measuring the temperature and pressure differences at the inlet and outlet ports of the plate-type heat exchanger

If the aged difference in the temperature or pressure has increased beyond the proper range, the flow rate should have decreased. Stop the operation and remove the cause before restarting the operation

3 Steps to be taken if a freeze-protection device is activated

If the freeze-protection device is activated during operation, be sure to remove the cause before restarting the operation. If the freeze-protection device has been once activated, a partial freezing has already occurred
