11.2.6 Reconfirmation
WARNING
Be sure to switch off all power supply before performing each
of the below checkings.
11.2.6.1 Check Water Pressure
*(0.1 MPa
= 1 bar)
Water pressure should not lower than 0.05 MPa (with
inspects the Water Pressure Gauge
⑮
). If necessary
add water into Tank Unit (via Tube Connector
○
a ).
11.2.6.2 Check Pressure Relief Valve
⑬
Check for correct operation of Pressure Relief
Valve
⑬
by turning on the lever to become
horizontal.
If you do not hear a clacking sound (due to water
drainage), contact your local authorized dealer.
Push down the lever after finish checking.
In case the water keep on draining out from the
Tank Unit, switch off the system, and then contact
your local authorized dealer.
11.2.6.3 Expansion
Vessel
⑪
Pre
Pressure Checking
For Space Heating
Expansion Vessel
⑪
with 10 L air capacity and
initial pressure of 1 bar is installed in this Tank
Unit.
Total amount of water in system should be below
200 L. (Inner volume of Tank Unit’s piping is about
5 L)
If total amount of water is over 200 L, please add
another expansion vessel. (field supply)
Please keep the installation height difference of
system water circuit within 10 m.
11.2.6.4 Check
RCCB/ELCB
Ensure the RCCB/ELCB set to “ON” condition before
check RCCB/ELCB.
Turn on the power supply to the Tank Unit.
This testing could only be done when power is
supplied to the Tank Unit.
WARNING
Be careful not to touch parts other than RCCB/ELCB test
button when the power is supplied to Tank Unit. Else,
electrical shock may happen. Before obtaining access to
terminals, all supply circuits must be disconnected.
Push the “TEST” button on the RCCB/ELCB. The
lever would turn down and indicate “0”, if it
functions normal.
Contact authorized dealer if the RCCB/ELCB
malfunction.
Turn off the power supply to the Tank Unit.
If RCCB/ELCB functions normal, set the lever to
“ON” again after testing finish.

mounted to the Tank Unit
can be moved to the room and serve as Room
Thermostat.
11.2.7.1 Installation
Location
Install at the height of 1 to 1.5 m from the floor
(Location where average room temperature can
be detected).
Install vertically against the wall.
Avoid the following locations for installation.
1 By the window, etc. exposed to direct sunlight
or direct air.
2 In the shadow or backside of objects deviated
from the room airflow.
3 Location where condensation occurs (The
Remote Controller is not moisture proof or drip
proof.)
4 Location near heat source.
5 Uneven surface.
Keep distance of 1 m or more from the TV, radio
and PC. (Cause of fuzzy image or noise)
