the water over heating. When
the Overload Protector 0 trip
at high water temperature,
take below steps to reset it.
1. Take out OLP Cover.
2. Use a test pen to push
the centre button gently
in order to reset the
Overload protector 0.
3. Fix the OLP Cover to the original fi xing condition.
CHECK WATER PRESSURE
Water pressure should not lower than 0.05 MPa (with inspects the
pressure gauge). 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 2
•
Take out the cover c with remove the
mounting screw for access to the pressure
relief valve 2.
•
Check for correction operation of pressure
relief valve by turn up the lever to become
horizontal (Refer to fi gure of "Pressure
relief valve 2")
•
If you do not hear a clacking sound (due

HOW TO ADJUST WATER FLOW RATE
Before adjust the water fl ow rate, make sure that the total water
volume in the installation is 50 litres minimum for heating side. The
default setting is SPEED 6 for WH-MXC16G9E8. Please ensure
the minimum fl ow rate is not less than 13 l/min and not more than
50 l/min.
The available external static pressure (kPa) in function of the water
fl ow rate (l/min) is shown in the P-Q graph. Depend on the hydraulic
system pressure loss and type, the water fl ow 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 confi rm the menu.
3. Press SELECT button then press / button to change pump
