11.2.6 Reconfirmation
Be sure to switch off all power supply before performing each
of the below checkings.
11.2.6.1 Check Water Pressure
= 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
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.

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
