Reconfirmation; Check Water Pressure; Check Pressure Relief Valve; Expansion Vessel Pre Pressure Checking - Panasonic WH-ADC0916H9E8 Service Manual

Reconfirmation

Be sure to switch off all power supply before performing each
of the below checkings.

Check Water Pressure

= 1 bar)
Water pressure should not lower than 0.05 MPa (with
inspects the Water Pressure Gauge). If necessary add
water into Tank Unit (via Tube Connector g).

Check Pressure Relief Valve


Check for correct operation of Pressure Relief
Valve 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.
Expansion Vessel Pre Pressure
Checking
For Space Heating / Cooling

Expansion Vessel 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.
Check RCCB
Ensure the RCCB set to "ON" condition before check
RCCB.
Turn on the power supply to the Tank Unit.
This testing could only be done when power is
supplied to the Tank
Be careful not to touch parts other than RCCB test button
when the power is supplied to Tank Unit. Else, electrical
shock may happen.

Push the "TEST" button on the RCCB. The lever
would turn down and indicate "0", if it functions
normal.

Contact authorized dealer if the RCCB
malfunction.

Turn off the power supply to the Tank Unit.

If RCCB functions normal, set the lever to "ON"
again after testing finish.
