Stopping during winter time
f Do not cut-off the power supply.
- This may result in water leakage or pipe damage
because pump will not operate to prevent
freezing. Do not cut-off the power supply for the
pump.
f Stop the operation with water pipe valve opened.
- Stop the operation with valve opened to make
water circulate when the pump operates. If the
water does not circulate, it may freeze and cause
product malfunction due to heat generated on
pump.
CaUtIon
• When outdoor temperature drops below zero during
winter, do not let water left in water pipe and water
side heat exchanger. It may cause plate type heat
exchanger freeze and get damage.
