When stopping the unit for long period.

If you do not use the unit for more than on month, shut the main power off and drain off from the

heat pump unit and the hot water storage unit as well.

The method for draining off, please consult with the installer or the dealer.

Request

When draining off, please shut off the power in advance according to the following procedure.

①

Stop the heat pump unit

Select the [Service & Maintenance] on the menu screen and select the [System off] on the

[Service & maintenance] menu screen.



The service password is required.

②

Shut off the power breaker of the heat pump unit and hot water storage unit.

When power failure occurs

If power failure occurs and water may freeze, shut off the main power and drain off from the heat

pump unit and the hot water storage unit as well.

Measure for anti-freezing water in winter

If the ambient temperature around the unit becomes below 0°C, the water pipe may freeze and it

may cause damage of the heat pump unit.

Please consult with the dealer and be sure to take proper measure for anti-freezing. And if the

water may freeze, please keep the power on supplying to the unit, even if the unit is pausing,

because the heat pump unit may start operation for anti-freezing.

CAUTION

If shutting the power breaker off during operation of the heat pump unit, it may cause
malfunction of the heat pump unit
