f
Check flow rate of chilled/heating water.
- Low flow rate of chilled/heating water may cause freezing. Check inlet/outlet of water side heat exchanger
for blocked strainer, noise occurred by vapor in filter impeller, decreasing flow rate by circulating pump
malfunction by measuring temperature or pressure difference. If flow rate decreased, stop the operation
and restart after removing the cause.
- Refer to page 68 for usage range.
f
For pump integrated models, daily and periodic check for pump is necessary.
