4.4.3 Installing the Hot Water Return Pipe
To preheat water with the NaviCirc, a hot water return pipe
should be installed. If there is no hot water return pipe where
the NaviCirc should be installed, install one. After installing the
hot water return pipe, install the 15 mm X ½” straight adapter
(provided with the NaviCirc) at the end of the pipe.

Note
●
When installing the 15 mm X ½” straight adapter,
the torque should be around 30 Nm.
●
Adjust the hot water pipe considering the
installation location of the NaviCirc as the flexible
hose is 500 mm long.
4.4.4 Connecting the Flexible Hoses
Connect the flexible hoses between the NaviCirc and water
pipes. The diameter of flexible hoseline is ½”.
CAUTION
●
Use the provided washers to seal the flexible hoses and
water pipes. Otherwise, a water leak may occur.
●
Connect the flexible hoses to the correct connections
of the NaviCirc and water pipes. Otherwise, the NaviCirc
may not function properly.
●
Ensure the flexible hoses do not bend. If they are bent,
the NaviCirc may not function properly and a noise may
occur while using it.
