Press the tab in the middle of the terminals to remove them.

Check that the terminals are securely locked in place after insertion.

3. Faston terminals have a locking function.

4. The symbols of the field connecting terminals are as follows.

1. The broken lines indicate the optional parts,field-supplied parts,and field work.

2. Dashed lines indicate sub box

5. The method of input signal of operation can choose one of optinal remote controller

6. Leave a space of at least 5 cm between the low voltage external wiring

use a separate cabtyre cable for the following wiring.

this will damage the circuit board.

7. When cabtyre cable is used for the control cable wiring,

(a) Optional remote controller wiring

(b) No-voltage contact input wiring

(c) No-voltage contact output wiring

Using the same cabtyre cable may cause malfunctions

and damage to the unit.

Connect the shield to the earth terminal.

Thread the wiring to the external water temperature sensor
through parts b) through d) as shown in the figure at right. Attach
M4 terminals (not supplied) to the wirings, and connect them to
e) and f) (terminals A and B).

After the wiring is connected, securely tighten the tightening
screw d), and then caulk the gap between the wiring a) and the
tightening screw to keep water from entering.

2. Flow sensor installation

Install the flow sensor on the pipe by following steps (1) through (3) below.
Install the flow sensor between the secondary-side pump and the heat exchanger.
Refer to the Installation/Operation Manual of QAHV-N560YA-HPB for details.

(1) Install an O-ring on the flow sensor and coupler 2 (OUT-side).

When installing the
quick fastener, use
caution not to let it
come in contact with
the wiring.

Hold the wiring with a cable tie.

Place a cable tie
over the protective
tube to hold the
wiring on the pipe.

Thread the cable tie
through the hole on
the quick fastener,
and hold the wiring
in place.

* The end with a smaller bore is the IN-side. Be sure to install

them in the correct orientation.

Attach the coupler to the pipe so that

the IN-side of the coupler faces up

and the OUT-side of the coupler

faces down. (Water flows from top

to bottom.) The incline of the pipe

should not exceed 5 degrees.

Keep the sensor away from water.

The flow sensor is 71.5 mm long.

Keep an appropriate distance

between the couplers.

Fit the flow sensor to the coupler.

Insert the flow sensor into the couplers,
and then fit the quick fasteners where
the flow sensor and the couplers are
connected to each other. Keep the
quick fasteners out of contact with the
wiring so as not to damage the wiring.
Hold the wiring to the quick fastener
with a (short) cable tie as shown in the
figure to keep the wiring from being
damaged.
Extend the length of the wiring as
necessary, using a terminal block.
Keep the wiring and the terminal block
dry.

Connect the flow sensor
wiring to the terminal block
inside the BOX. The numbers
on the wirings correspond to
the numbers on the terminal
block.
Connect each wiring to the
correct terminal.
When done, hold the excess
wiring with the supplied cable
tie (long).
Also, hold the wirings in
place with a cable tie (long)
where indicated as B in the
figure to keep them out of
contact with the pipes and
other components.

(4) Close the panel.

Using a screwdriver, re-place the SERVICE PANEL and the CONTROL BOX (SUB) cover.

4. Cautionary notes

Note the following when performing wiring work.

Turn off the power before performing wiring work to avoid electrocution.
Watch for sharp edges of sheet metal.
Keep external wiring at least 5 cm away from wiring that carries 100 V or higher.
Do not bundle the wiring together with strong current wiring.
Connect wiring in a way that minimizes electrical noise interference. Shield the wiring to minimize external effects.
Install the flow sensor indoors, and insulate it as necessary to keep it from being exposed to subzero temperatures.
Keep the wiring and the terminal block dry.
