CHARGE THE WATER
For Domestic Hot Water Tank
1. Set the Domestic Hot Water Tank Discharge (Drain Tap)
g
to “CLOSE”.

2. Set all Tap / Shower “OPEN”.
3. Start fi lling water to the Domestic Hot Water Tank via Tube Connector
i
.
After 20~40min, water should fl ow out from Tap / Shower.
Else, please contact your local authorized dealer.
4. Check and make sure no water leaking at the tube connecting points.
5. Set the Domestic Hot Water Tank Discharge (Drain Tap)
g
to
“OPEN” for 10 seconds to release air from this pipeline. Then set
it “CLOSE”.
6. Turn the Safety Relief Valve
o
knob counterclockwise slightly and
hold for 10 seconds to release air from this pipeline. Then recover
the knob to original position.
7. Ensure Step 5 & 6 is carried out each time after charging water to
Domestic Hot Water Tank.
8. To prevent back pressure from happening to the Safety Relief
Valve
o
, do turn the Safety Relief Valve
o
knob counterclockwise.
For Space Heating / Cooling
1. Turn the plug on the Air Purge Valve
d
outlet anticlockwise by one
complete turn from fully closed position.

3. Start fi lling water (with pressure more than 0.1 MPa (1 bar)) to the
Space Heating / Cooling circuit via Tube Connector
a
. Stop fi lling water
if the free water fl ow through Pressure Relief Valve
e
discharge hose.
4. Turn ON the Tank Unit and make sure Water Pump
4
is running.
5. Check and make sure no water leaking at the tube connecting points.
6. The water may drip from this discharge hose. Therefore must guide
the hose without close or block the outlet of the hose.

2. An isolating device must be connected to the power supply cable.
•
Isolating device (disconnecting means) should have minimum
3.0 mm contact gap.
•
Connect the approved polychloroprene sheathed power
supply 1 cord and power supply 2 cord and type designation
60245 IEC 57 or heavier cord to the terminal board, and to the
other end of the cord to isolating device (Disconnecting means).
