•
Provide a 50 mesh or more water strainer at the water inlet side of
water piping. Otherwise, damage to the plate heat exchanger may
occur. In the plate heat exchanger, water flows through a narrow
space between the plates.Therefore, there is a possibility that
freezing or corrosion may occur if foreign particles or dust clog the
flow of water between the plates.
This is not required when cooling mode is not used.
