RECONFIRMATION
6
Be sure to switch off all power supply before performing each of
the below checkings.
CHECK WATER PRESSURE
Water pressure should not lower than 0.05 MPa (with inspects the
Water Pressure Gauge e). If necessary add water into Tank Unit
(via Tube Connector g).
g
CHECK PRESSURE RELIEF VALVE c
• Check for correct operation of Pressure Relief Valve c 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 fi nish checking.
•
In case the water keep on draining out from the Tank Unit, switch
off the system, and then contact your local authorized dealer.
EXPANSION VESSEL a PRE PRESSURE CHECKING
For Space Heating / Cooling
• Expansion Vessel a 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. (fi eld supply)
•
Please keep the installation height difference of system water
circuit within 10 m.
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.
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.
•
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 fi nish.
