15 Servicing Mode
15.1. Test Run
1. Fill up the boiler tank with water. For details refer to boiler tanks installation instruction and operation instruction.
2. Set ON to the indoor unit and RCCB. Then, for control panel’s operation please refers to air-to-water heatpump’s operation
instruction.
3. For normal operation, pressure gauge reading should be in between 0.05 MPa and 0.2 MPa.
If necessary, adjust the water pump speed accordingly to obtain normal water pressure operating range. If adjust water pump
speed cannot solve the problem, contact your local authorized dealer.
15.2. Proper Pump Down Procedure
1. Make sure the OFF/ON control panel LED is OFF (no operation).
2. Press the “PUMPDW” switch on control panel to begin PUMP DOWN mode. Operate the system in PUMP DOWN mode for
10 ~ 15 minutes.
3. After 10-15 minutes, (after 1 or 2 minutes in case very low ambient temperatures (< 10
°
C)), fully close 2 way valve.
4. After 3 minutes, fully close 3 way valve.
5. Press the “OFF/ON” switch on control panel to stop PUMP DOWN mode.
6. Remove the refrigerant piping.
15.3. How To Adjust Water Flow Rate
• Before adjust the water flow rate, make sure that the total water volume in the installation is 30 litres minimum (07C3 & 09C3),
50 litres minimum (12C6, 14C6 & 16C6).
• The water flow rate can be adjusted with select the water pump speed on the water pump. The default setting is high speed (III).
Adjust it to moderate speed (II) and slow speed (I) if necessary (e.g. reduce the noise of running water).
Below graph shown the external static pressure (kPa) versus water flow rate (l/min).
• Flow rate characteristic of indoor unit is as per above mentioned.
15.4. Expansion Vessel Pre Pressure Checking
• Expansion Vessel with 10L air capacity and initial pressure of 1 bar is installed in this indoor unit.
• Total amount of water in system should be below 200L.
(Note: This amount of water is not include the tank unit volume)
• If total amount of water is over 200L, please add expansion vessel.
• Please keep the installation height difference of system water circuit within 7m.
(Inner volume of same indoor unit is about 5L)
