Replace The Remote Controller Cover
•
Replace the existing Remote controller cover with Remote controller
cover 6 to close the hole left after remove the Remote controller.
1. Release the Remote controller cover's hooks from behind the
front plate.

CHARGING THE WATER
•
Make sure all the piping installations are properly done before
carry out below steps.
1. Turn the plug on the Air Purge Valve 9 outlet anticlockwise by
one complete turn from fully closed position.

3. Start filling water (with pressure more than 0.1 MPa (1 bar)) to
the Indoor Unit via water inlet. Stop filling water if the free water
flow through Pressure Relief Valve drain hose.
4. Turn ON the power supply and make sure Water Pump f is
running.
5. Check and make sure no water leaking at the tube connecting
points.

RECONFIRMATION
WARNING
Be sure to switch off all power supply before performing each of
the below checkings. Before obtaining access to terminals, all
supply circuits must be disconnected.
CHECK WATER PRESSURE
Water pressure should not lower than 0.05 MPa (with inspects the
Water Pressure Gauge d). If necessary add tap water into Tank
Unit. Refer to Tank unit installation instruction for details on how to
add water.
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 finish checking.
•
In case the water keeps drained out from the unit, switch off the
system, and then contact your local authorized dealer.
EXPANSION VESSEL b PRE PRESSURE CHECKING
[Upper limit water volume of the system]
The indoor unit has a build-in Expansion Vessel with 10 L air
capacity and initial pressure of 1 bar.
Total amount of water in the system should be below 260 L.
If the total amount of water is more than 260 L, please add
expansion vessel (field supply).
The expansion vessel capacity required for the system can be
calculated from the formula below.
V =
1 -
V : Required gas volume <expansion vessel volume L>
Vo : System total water volume <L>
: Water expansion rate 5

P : Expansion tank filling pressure = (100) kPa

P : System maximum pressure

It's advised to add 10% margin for required gas volume of calculation.

[Adjustment of the initial pressure of the expansion vessel when
there is a difference in installation height]
If the height difference between the indoor unit and the highest
point of the system water circuit (H) is more than 7m, please adjust
the initial pressure of the expansion vessel (Pg) according to the
following formula.
Pg= (H*10+30) kPa
