WARNING
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 f). If necessary add water into Tank Unit (via Tube

CHECK PRESSURE RELIEF VALVE d
•
Check for correct operation of Pressure Relief Valve d 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 b PRE PRESSURE CHECKING
For Space Heating / Cooling
•
Expansion Vessel b 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
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 Unit.
WARNING
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 fi nish.
TEST RUN
7
1. Before test run, make sure below items have been checked:-
a) Pipework are properly done.
b) Electric cable connecting work are properly done.
c) Tank Unit is fi lled up with water and trapped air is released.
d) Please turn on the power supply after fi lling the tank until full.
e) In order to check whether the tank is full, switch heater once for about
10 min.
2. Switch ON the power supply of the Tank Unit. Set the Tank Unit RCCB
to "ON" condition. Then, please refer to the Operation Instruction for
operation of Control Panel 1.
3. For normal operation, Water Pressure Gauge f reading should be in
between 0.05 MPa and 0.3 MPa. If necessary, adjust the Water Pump
2 SPEED accordingly to obtain normal water pressure operating
range. If adjust Water Pump 2 SPEED cannot solve the problem,
contact your local authorized dealer.
4. After test run, please clean the Water Filter Set 6. Reinstall it after
fi nish cleaning.
