6 Check the rated flow rate of cold / hot water and the
pressure loss inside the heat exchanger.
CAUTION
• If the rated flow rate is not supplied, it may cause
performance degradation and product malfunction.

Step 9 Installing the drain pipe
-
• D rain hoses and PVC pipes are sold separately.
• Before installing the drain pipe, be sure to check if
-
drainage is good.

2 Tighten the metal clamp as shown in the figure.
3 Wrap the metal clamp and the drain hose with a
sealing pad for insulation, and then fix them with a
clamp.
4 Fully insulate the drain pipe inside the building (on
site).
If the drain pipe is sloped insufficiently, install the
drain pipe vertically from the hose connection port
(on site).
5 When connecting the drain hose to the drain socket,
connect the drain hose by pushing it up.

Be sure to bond the drain
hose and the main pipe.
When tightening the clamp,
tighten as tight as possible so
that the eight holes are visible.
