14.4 Proper Pump Down Procedure
Strictly follow the steps below for proper pump down procedure. Explosion may occur if the steps are not
followed as per sequence.
1. Press the “SERVICE” switch on remote control to enter SERVICE mode. Operate the system in Sr : 01 mode
for pump down operation.
2. After 10~15 minutes, (after 1 or 2 minutes in case very low ambient temperatures (< 10°C)), fully close 2 way
valve.
3. After 3 minutes, fully close 3 way valve.
4. Press the “OFF/ON” switch on remote control to stop pump down operation.
5. Remove the refrigerant piping.
14.5 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 for
heating side. The default setting is SPEED 3 (Only for WH-MDC06G3E5) and SPEED 6 for WH-MDC09G3E5.
Please ensure the minimum flow rate is not less than 9 l/min and not more than 35 l/min.
The available external static pressure (kPa) in function of the water flow rate (l/min) is shown in the P-Q graph.
Depend on the hydraulic system pressure loss and type, the water flow rate can be adjusted by remote control.
1 When the Air-to-Water Heatpump is in stop operation, press SERVICE button for 5 seconds.
2 Press /button to select menu S02 (PUMP SPEED ADJUST MODE) and press SET button to confirm the
menu.
3 Press SELECT button then press /button to change pump speed and press SET button to confirm the
pump speed.
4 Press OFF/ON button to exit PUMP SPEED ADJUST MODE.
During PUMP SPEED ADJUST MODE, we can select AIR PURGE function by pressing FORCE button.
In AIR PURGE function, the pump will operate ON and OFF for 10 minutes to purge the air in the hydraulic system.
Press again the FORCE button to exit AIR PURGE function. PUMP SPEED ADJUST
MODE will stop operation.

14.6 Expansion Vessel Pre Pressure Checking
Expansion Vessel with 10 L air capacity and initial pressure of 1 bar is installed in this Mono bloc unit.
Total amount of water in system should be below 200 L.
(Note: This amount of water is not include the tank unit volume)
If total amount of water is more than 200 L, please install additional expansion vessel (field supply).
Please keep the installation height difference of system water circuit within 10 m.
(Inner volume of same Mono bloc unit is about 5 L)
