Note 1. At the time of product shipment, the front side piping specification serves as the local drainage connection. When connecting on the rear side, please remove the rear side plug sealing corks, and attach to a front side. Ensure there is no leak after the attachment has been fitted.

2. Take notice of service space as Fig. A (In case of single setting, 600mm or more of back space as front space makes easier access when servicing the unit from the rear side.)3. In case the temperature around the heat source unit has possibility to drop under 0°C, be careful for the following point to prevent the pipe burst by the water pipe freeze-up.

• Circulate the water all the time even if the heat source unit is not in operation.• Drain the water from inside of the heat source unit when the heat source unit will not operate for a long term.
