CHARGING THE WATER
7
• Make sure all the piping installations are properly done before
carry out below steps.
1. Start filling water (with pressure more than 1 bar (0.1MPa)) to
the Space Heating /Cooling circuit via Tube Connector g.
2. Stop filling water if the free water flow through Pressure Relief
Valve drain pipe. (Check the Outdoor Unit)
3. Turn ON the Indoor Unit.
4. Remote control menu Installer setup
pump maximum speed
5. Make sure Water Pump d is running.
6. Check and make sure no water leaking at the tube connecting
points.

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 0.5 bar (with inspects the Water
Pressure Sensor b). If necessary add water into Indoor Unit.
Fill with water from Tube Connector g.
Service setup
Turn on the pump.
Pressure Relief Valve drain pipe
Pressure Relief Valve
WARNING
*(1 bar = 0.1 MPa)
CHECK PRESSURE RELIEF VALVE
* Pressure Relief Valve is mounted in the Outdoor Unit.
1. Confi rm that the pressure relief valve is working properly, pull the
lever horizontal direction.
2. Release the lever when water comes out of the drain pipe of the
pressure relief valve.
(While the air continues to come out of the drain pipe, keep
raising the lever to completely discharge the air.)
3. Confi rm that the water from the drain pipe stops.
4. If water is leaking, pull the lever several times and return it to
make sure the water stops.
5. If water keeps coming out of the drain, drain water.
Turn off the system and contact your local authorized dealer.
CHECK AIR ACCUMULATION
•
Open the air vent plugs on the heating panel, fan convector, etc.,
and remove the air accumulated in the equipment and piping.
•
If the outdoor unit and the indoor unit are installed on different
fl oors, open the air vent plug on the water plug of the outdoor unit
and the air vent plug on the heater bottle inside the indoor unit to
remove the air. (be careful, water will come out)
EXPANSION VESSEL a PRE PRESSURE CHECKING
[Upper limit water volume of the system]
•
The Indoor Unit has a build-in Expansion Vessel with 10 L air
volume and initial pressure of 1 bar. (1bar = 100kPa = 0.1MPa)
•
Total amount of water in the system should be below 200 L.
•
Inner volume of Indoor Unit piping is about 5L.
•
If the total amount of water is more than 200 L, please add
expansion vessel (fi eld supply).
•
Please keep the installation height difference of system water
circuit within 10 m. (Extra pump may be required)
•
The expansion vessel volume 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 fi lling pressure = (100) kPa

P : System maximum pressure

- ( ) Please confi rm at actual place
- The gas volume of the sealed type expansion vessel is presented by <V>.
 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
