14.1 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.
4 After test run, please clean the external filter. Reinstall it after finish cleaning.
14.2 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 3 way
valve (Liquid Side).
4 After 3 minutes, fully close 3 way valve (Gas Side).
5 Press the “OFF/ON” switch on control panel to stop PUMP DOWN mode.
6 Remove the refrigerant piping.
14.3 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
(UD09CE) and 50 litres minimum (UD12CE, UD14CE & UD16CE).
The water flow rate can be adjusted with select the water pump speed on the water pump. The default setting is
moderate speed (II). Adjust it to high speed (III) 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.
14.4 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)
