d) Please turn on the power supply after fi lling the tank until full.
2. Switch ON the power supply of the Tank Unit. Set the Tank
Unit RCCB /ELCB to "ON" condition. Then, please refer to the
Operation Instruction for operation of Remote Controller 1.
3. For normal operation, Water Pressure Gauge d reading should
be in between 0.05 MPa and 0.3 MPa. If necessary, adjust the
Water Pump 2 SPEED accordingly to obtain normal water
pressure operating range. If adjust Water Pump 2 SPEED
cannot solve the problem, contact your local authorized dealer.
4. After test run, please clean the Magnetic Water Filter Set 6.
Reinstall it after fi nish cleaning.
CHECK WATER FLOW OF WATER CIRCUIT
Confi rm the maximum water fl ow during main pump operation not
less than 15 l/min.
*Water fl ow can be check through service setup (Pump Max Speed)
[Heating operation at low water temperature with lower water fl ow
may trigger "H75" during defrost process.]
RESET OVERLOAD PROTECTOR 9
Overload Protector 9 a serves the safety purpose to prevent the
water over heating. When the Overload Protector 9 a trip at high
water temperature, take below steps to reset it.
1. Take out the cover.
2. Use a test pen to push the centre button gently in order to reset
the Overload Protector 9.
3. Fix the cover to the original fi xing condition.
MAINTENANCE

•
In order to ensure safety and optimal performance of the Tank
Unit, seasonal inspections on the Tank Unit, functional check
of RCCB/ELCB, fi eld wiring and piping have to be carried out
at regular intervals. This maintenance should be carried out by
authorized dealer. Contact dealer for scheduled inspection.
Maintenance for Magnetic Water Filter Set
1. Turn OFF power supply.
2. Set the two valves for the Magnetic Water Filter Set 6 to "CLOSE".
3. Drain the Space Heating / Cooling circuit water with set the
Pressure Relief Valve b lever UP, so that water pressure drop
below 0.5 bar.
4. Take off the clip, then gently pull out the mesh. Beware of small
amount water drain out from it.
5. Clean the mesh with warm water to remove all the stain. Use soft
brush if necessary.
6. Remove the bolt with magnet on brass cap with screwdriver to
remove all iron powder.
7. Reinstall the magnet and mesh to the Magnetic Water Filter Set
6 and set back the clip on it.
8. Set the two valves for the Magnetic Water Filter Set 6 to "OPEN".
9. Re-charging the water to Space Heating / Cooling circuit
(refer Section 5 for details.)
10. Turn ON power supply.

Maintenance for Safety Relief Valve k
•
It is strongly recommended to operate the valve by turn the knob
counter clockwise to ensure free water fl ow through discharge
pipe at regular intervals to ensure it is not blocked and to remove
lime deposit.
PROPER PUMP DOWN PROCEDURE
WARNING
Strictly follow the steps below for proper pump down procedure.
Explosion may occur if the steps are not followed as per sequence.

Service setup menu in the Remote Controller and select Pump
down operation to turn it ON. (See APPENDIX for detail)
2. After 10~15 minutes, (after 1 or 2 minutes in case very low
ambient temperatures (< 10°C)), fully close 2 way valve on
Outdoor Unit.
3. After 3 minutes, fully close 3 way valve on Outdoor Unit.
4. Press the "OFF/ON" switch on the Remote Controller 1 to
stop pump down operation.
5. Remove the refrigerant piping.
